     DETAILED DESCRIPTION 
     Reference will now be made in detail to representative embodiments illustrated in the accompanying drawings. It should be understood that the following description is not intended to limit the embodiments to one preferred embodiment. To the contrary, it is intended to cover alternatives, modifications, and equivalents as can be included within the spirit and scope of the described embodiments as defined by the appended claims. 
     The embodiments described herein are generally directed to electronic devices, such as smartphones and tablet computers, having enclosures that are formed from glass. Conventionally, glass has been used in such devices to provide a transparent window over a touchscreen on a front of the device. Described herein, however, are electronic devices with enclosures that use glass to define multiple sides of the enclosure. For example, an enclosure that takes the general form of a rectangular prism may include a glass front, a glass back, and one or more glass sides. In some cases, substantially the entire enclosure (e.g., all exterior surfaces of the enclosure) is formed of glass, including the front, back, and all sides of the enclosure. In such cases, the enclosure may appear visually and tactilely seamless, such that the entire enclosure may appear to be formed from a single piece of glass (even though it may be formed from multiple separate pieces attached together). 
     Enclosures having glass defining multiple sides of the enclosure may facilitate or enable numerous additional functions and uses that are not realized with conventional enclosures. For example, glass backs and glass sides may be transparent, allowing the electronic device to include additional displays that are viewable through the sides and/or the back. Moreover, the side- and back-viewable displays may be made touch and/or force sensitive using touch- and/or force-sensing systems, effectively turning the side and back surfaces into additional input devices or surfaces with which a user may interact to control the electronic device. 
     The physical distinctions between the front, back, and side surfaces of the glass enclosures may indicate functional distinctions of the touchscreens, or display regions, corresponding to those surfaces. For example, while a front-facing touchscreen may present or define a main display region (e.g., for displaying application windows, games, grids of selectable icons), a side-facing touchscreen may display an auxiliary display region (e.g., for displaying affordances that control functions of the electronic device such as speaker volume, ring/silent, screen brightness, or the like). A back surface may display an additional auxiliary display region, which may include different content than the front or side surface(s). For enclosures having alternative shapes, such as cylinders or triangular prisms, the distinct sides and/or surfaces of those enclosures may indicate or suggest similar functional distinctions. The physical distinctions between the various surfaces may thus help to indicate functional distinctions between the user interfaces or affordances presented on the corresponding displays. 
     While the physical distinctions between the surfaces can be used to define or delineate functionally different regions of the device, an enclosure with multiple glass sides (and displays that are visible through the multiple glass sides) may also be used to erase or blend the distinctions between the various surfaces of the device. For example, under certain conditions, such a device may display graphical outputs (e.g., images, videos, etc.) that span multiple displays and sides of the device. For example, a single displayed graphical output (e.g., image, user interface, etc.) may wrap or extend over a front side, one or more peripheral sides, and a back side of the device, thus contributing to the unified appearance of the multiple sides. As another example, a primary user interface may extend over a front side, one or more peripheral sides, and a back side of the device (or, in the context of a cylindrical enclosure, the primary user interface may extend around the round cylindrical wall of the enclosure). This may allow icons to move across multiple surfaces when swiped, and may even allow icons or other graphical outputs to appear as a ribbon-like user interface that wraps around the device. For example, a user interface may be continuously scrollable in a left-right direction such that an icon or other graphical output may be scrolled off of a front side, over a peripheral side and on to a back side. If the user interface is further scrolled, the icon or other graphical output may be scrolled over another peripheral side to return to the front side. Similar scrolling effects may be realized in other directions as well (e.g., up-down, diagonally, etc.), producing a continuous scroll phenomenon around the entire device. In the case of a cylindrical enclosure, for example, the user interface may continuously scroll around the cylindrical wall. Accordingly, while in some cases the various surfaces of a device may be used to help distinguish different areas (e.g., based on the type of graphical outputs or functions provided on those areas), an enclosure with multiple transparent glass sides or surfaces, and corresponding displays, may also minimize such distinctions to form a functionally and visually unified display region that spans multiple surfaces. 
     As noted above, in some cases, all or substantially all of the exterior surfaces of an enclosure may be formed from glass, and may further include a display region associated with substantially all of the exterior surfaces. In such cases, distinctions between the top and bottom or front and back of the device may effectively disappear. For example, where a device includes transparent glass surfaces and corresponding displays for both the front and back surfaces, either surface may be used as a primary interface surface at any given time, effectively eliminating the traditional notion of a physical “front” and a “back” of the device. Indeed, the “front” and “back” of the device may be defined not by any particular physical characteristic of the device itself, but rather by which surface is facing a user or being interacted with at a given time (or by the content that is being presented on a particular face or faces). 
       FIGS. 1A-1B  show front and back views of an example electronic device  100  in accordance with the concepts described herein. The electronic device  100  may include an enclosure  102  formed of glass. The enclosure  102  may define a first major side  104  (e.g., resembling a conventional “front” of the device), a second major side  106  (e.g., resembling a conventional “back” of the device), and first, second, third, and fourth peripheral sides  108 ,  110 ,  112 ,  114 , respectively, all of which may be formed from glass and which may be transparent. The glass enclosure  102  may be formed from a single (e.g., monolithic) glass member or multiple glass members attached together. Techniques for forming such enclosures are described in greater detail herein. 
     As used herein, the term “monolithic” may be used to refer to a component or object that is formed from a single piece of material, and may have a uniform or substantially uniform material composition throughout. For example, an enclosure member formed of a single, continuous piece of glass with a uniform composition may be referred to as a monolithic enclosure member. A monolithic component may include chemically strengthened regions, coatings, and other treatments and may still be considered to have a substantially uniform material composition. Monolithic components or objects may also be referred to herein as unitary components or objects. By contrast, non-monolithic structures may include those formed by bonding two separate components together (e.g., with a distinct material, such as an adhesive). 
     The electronic device  100  may also include a display  116  within the enclosure  102 . The display  116  may display graphical output that is visible through the first and second major sides  104 ,  106  and the peripheral sides of the enclosure  102 . For example, the display  116  may include a first major display side  132  (visible through the first major side  104  of the enclosure  102 ), a second major display side  134  ( FIG. 1B , visible through the second major side  106  of the enclosure  102 ), and first, second, third, and fourth peripheral display sides  136 ,  138 ,  140 ,  142  (visible through the first, second, third, and fourth peripheral sides  108 ,  110 ,  112 ,  114 , respectively). 
     The display  116  may include a single display member (e.g., a flexible substrate or display component, or a stack-up of flexible layers) that is wrapped or folded to define surfaces that direct images through all the sides of the enclosure. In another example, the display  116  may include multiple display members or panels that are assembled or fitted together to produce a substantially omni-directional visual output. The electronic device  100  may also include touch- and/or force-sensing systems associated with, on, beneath, and/or integrated into any or all of the sides of the enclosure, thus allowing any or all of the viewable regions of the display  116  to act as input devices (e.g., touchscreens) with which a user can control and/or interact with the electronic device  100 . 
     In order to produce a device with multiple displays viewable through multiple transparent sides—including embodiments where displays are visible through each of the six main sides of the device—the enclosure  102  must be sufficiently transparent and visually seamless to facilitate adequate visibility and to reduce or eliminate optical disturbances or artifacts. Thus, the enclosure  102  may be formed using techniques that reduce the number and/or visibility of seams between different glass components, and that reduce or eliminate visible physical structures, frames, and/or stiffeners, that are visible through the glass. For example, glass components that define three, four, five, or even six of the main sides of the device may be used to help increase the number of walls that are defined by a single, monolithic glass structure. Moreover, where glass members must be joined together, the seams may be formed and bonded in a way that reduces the visibility of the seams. Other techniques for forming, reinforcing, stiffening, and/or assembling the device  100  (and the enclosure  102  more particularly) are discussed herein. 
     Because substantially the entire enclosure  102  is transparent, the display  116 , and more particularly graphical outputs displayed by the display  116 , may be viewed through any surface of the enclosure  102 . Moreover, by virtue of the display  116  being visible through each of the sides of the enclosure  102 , the display  116  may be essentially the only component of the device that is visible through the sides of the enclosure  102 . This may provide a distinctive aesthetic appearance, whereby the display  116  appears suspended within a solid glass body. In some cases, the enclosure  102  may be configured so that when the display  116  is active, the glass enclosure  102  appears to vanish, such that the device appears to be a display with no external enclosure. Moreover, due to the symmetry of the enclosure  102  and the omni-directional visual output that may be facilitated by the display  116 , the electronic device  100  may appear to lack constraints on how the device may be handled and interacted with. For example, there may be no dedicated or visually distinguishable “front” or “top” of the device. Further, as described herein, the device may dynamically change its operation based on how it is handled and/or being used, allowing the device to provide the same functionality and user experience no matter how the device is handled. 
       FIGS. 1A-1B  show the display  116  displaying various graphical outputs, with the different sides of the enclosure  102  defining or suggesting differences in the type or function of graphical output displayed on the various sides. For example,  FIG. 1A  shows a first graphical output being displayed through the first major side  104 , a second graphical output being displayed through the first peripheral side  108 , and a third graphical output being displayed through the fourth peripheral side  114 . As shown, the first graphical output may be a main page of a graphical user interface (GUI) of the device  100 , which may display multiple icons  117  that a user may select to launch applications, programs, or the like. The second graphical output is shown displaying other information, in this case a region or window  124  showing updates on stock prices, and a region or window  125  showing weather data. The third graphical output includes affordances that may control device functions, such as speaker volume affordances  130 , a WiFi affordance  131 , and an “airplane mode” affordance  127 . Affordances may control device functions and may also provide information about the status of the device and/or the device function that is controlled by an affordance. For example, the WiFi affordance  131  may allow a user to activate or deactivate a wireless radio, and may also have a color that indicates the status of the wireless radio (e.g., a blue color indicating that the radio is active and a yellow color indicating that the radio is inactive). Any of the graphical outputs on these display regions may be non-moving (e.g., static images), or they may be dynamic (e.g., animated icons, scrolling text, or other moving/changing images). It will be understood that these particular graphical outputs, and their relative appearances and locations on the display  116 , are examples, and other graphical outputs may be displayed on these (or other) regions of the device. 
     Though the display  116  may be or may appear to be continuous across adjacent surfaces, the display regions may be distinguishable by a user as having different functional purposes based on the physical distinctions between the various sides of the enclosure. For example, a user may easily differentiate between the types of functions and information presented through the first major side  104  and the fourth peripheral side  114  based on the physical distinctiveness of those surfaces. However, while different functional regions may be physically differentiated by the various sides of the device, the continuity of the display between the various display regions reduces visual boundaries between the regions and produces a more integrated display appearance. 
     The appearance of continuity between display regions may be enhanced by images (e.g., background images) that span multiple display regions or sides of the device. For example, a single, continuous background image may extend across two, three, four, five, or all six of the sides of the device. For example, the single background image in  FIGS. 1A-1B  includes a tree  128  that extends across multiple display regions. More particularly, the tree  128  extends from the first major side  104 , over the fourth peripheral side  114 , and onto the second major side  106  ( FIG. 1B ). Other aspects or displayed items of the background image may extend across other sides, and indeed a single, seamless image may be presented that extends over multiple sides of the device. Displaying a continuous background image in this fashion may further the appearance of a single, continuous display. At the same time, displaying distinct graphical outputs on each side of the device, such as the icons  115  and affordances  130 , leverages the physical distinctions between the various sides to reinforce the concept of distinct functional and/or informational regions being afforded on different sides of the device. 
     While in some cases the side surfaces may be used to define distinct functional display regions (as described in greater detail herein), the device  100  may selectively join or unify functional display regions to eliminate functional distinctions and use a greater amount of the display for a single purpose. For example, when the device  100  is being used to display a movie, the peripheral sides of the device  100  may display a video image or a border around the video image, and other graphical outputs may therefore be removed from the peripheral sides. As another example, if the device  100  is being used to show thumbnails of photographs, the displayed thumbnails may extend onto the peripheral sides of the enclosure  102  (and may be scrollable over the peripheral and main sides of the enclosure  102 ), making essentially the entire device (or at least 5 sides of the device) into a single functional display region. The continuity of the display  116  across various surfaces (e.g., surfaces corresponding to the main and peripheral sides of the enclosure  102 ) may thus be dynamically changed to suit various contexts and functions of the device, and distinct functional regions may be created or eliminated based on the context of the device. 
       FIG. 1B  shows another view of the device  100 , with the second major side  106  facing up. Due to the symmetrical nature of the enclosure  102  and the omni-directional display  116 , the second major side  106  may visually indistinguishable from the first major side  104 . Nevertheless, in some cases (such as a dynamic determination that the device  100  is being held by a user such that the second major side  106  is the back of the device  100 ), the second major side  106  may be used to display different graphical outputs than the first major side  104 . For example, as shown in  FIG. 1B , the second major side  106  displays graphical outputs including a logo  120  and a device status identifier  122 . These graphical outputs may be selected in response to the device  100  determining that the first major side  104  is being used as a primary interface surface for the device  100 , and they may change based on the changing status of the device. For example, the “on call” device status identifier  122  shown in  FIG. 1B  may change to an “available” status indicator upon termination of a voice call. Similarly, all of the graphical outputs on the second major side  106  may be replaced with a primary user interface screen upon determination that a user has flipped the device in his or her hand and has begun using the second major side  106  as the primary interface surface of the device. 
     As suggested above, because both the first and second major sides  104 ,  106  may be associated with a display, either side may serve as a primary or main interface surface of the device  100 . The side that serves as the primary interface surface may be dynamically selected in any suitable way. In some cases the physical orientation or a physical relationship between the device  100  and another object (e.g., a user) may determine which side will display the primary interface surface. For example, a biometric sensing system (e.g., a face recognition system) may determine which major side is being viewed by a user, and the device  100  may establish that major side as the primary interface surface. As another example, a touch sensing system (optionally along with accelerometers, gyroscopes, or the like) may determine how a device is being held in a user&#39;s hand, and establish the side that is not occluded by a user&#39;s grip as the primary interface surface. In other cases, the primary interface surface may alternate between the major sides on a time-based schedule (e.g., switching at a set interval). In yet other cases, the side that acts as the primary interface surface may be selected by a user, and the selection may persist until the user changes the selection or allows the device to automatically determine which major side to designate as the primary interface surface. In yet other cases, the side that acts as the primary interface surface may be determined by an active application or function. For example, in a device with a speaker and/or microphone on only one side, that side may be selected as the primary interface surface when a voice calling application or function is active. That same device, however may allow either main side to be designated as the primary interface surface when an internet browser application is active. 
     In order to facilitate use of the device  100  in multiple orientations (e.g., such that the device has no dedicated top or front, and the active “front” of the device  100  can be dynamically determined), hardware components of the device  100  may be arranged symmetrically about the device  100 . For example, as described herein, both of the major sides  104 ,  106  of the device  100  may include a speaker and a microphone that are configured to output and capture audio, respectively, based on the particular side that is being used as the front or primary interface surface of the device  100 . In some cases, each major side  104 ,  106  has a speaker and a microphone at each end (e.g., corresponding to a conventional top and bottom of the device  100 ) so that the device has no distinct top or bottom, and can be rotated 180 degrees while still maintaining full functionality. That is, not only can either major side  104 ,  106  be dynamically selected as the “front” of the device  100 , but either end of the device  100  can be dynamically selected as the “top” of the device. In this way the device  100  may provide substantially identical functionality no matter which side is facing the user and which side is oriented as a “top” of the device. Examples of symmetrical hardware arrangements are discussed herein. Further, while the foregoing example relates to symmetrically positioned speakers and microphones, other hardware may also be arranged to facilitate the orientation independent usability of the device, such as cameras, projectors, flashes, sensors, etc. 
       FIG. 2  shows a cross-sectional view of a device  200 , which may be an embodiment of the device  100  described herein, as viewed along line A-A in  FIG. 1B .  FIG. 2  shows representative components within the interior volume of an enclosure  201  of the device  200 . The enclosure  201  may be similar and/or identical to the enclosure  102  described with respect to  FIGS. 1A-1B . As described above, the enclosure  201  may define an interior volume, and a display  216  (which may be the same as or similar to the display  116  in  FIGS. 1A-1B ) may be positioned in the interior volume and visible through the sides of the enclosure  201 .  FIG. 2  illustrates how light (e.g., corresponding to images produced by the display  216 ) may be emitted and visible through multiple sides and portions of the enclosure  201 . For example, arrows  202  indicate light and/or images being displayed through the major sides of the enclosure  201 , while arrows  204  indicate light and/or images being displayed through peripheral sides of the enclosure  201 . Further, light and/or images may be displayed through corner or transition regions between the major and peripheral sides of the enclosure  201 , as shown by arrows  206 . 
     As shown, the display  216  may conform to and optionally contact the inside surface of the enclosure  201 . For example, the shape of the interior surface of the enclosure  201  may be substantially identical to the shape of the exterior-facing surface of the display  216 . In other cases, all or portions of the display  216  may be offset from the inside surface of the enclosure  201 . For example, some or all of the display  216  may be set apart from the inside surface by an air gap. As another example, a transparent material (e.g., a liquid, transparent film, adhesive, or other suitable material or component) may be positioned between the inside surface of the enclosure  201 . Such interstitial materials may be part of a touch and/or force sensing system. Display components and touch and/or force sensing systems may be at least partially integrated, structurally and/or functionally, to define a touchscreen display assembly. The display  216  may be a touchscreen display assembly, or a portion thereof. Indeed, any display or display component described herein may be integrated with touch and/or force sensing systems to define a touchscreen display assembly. 
     The device  200  may also include internal device components  208 , which are within the interior volume of the enclosure  201  and are at least partially surrounded by the display  216 . The internal device components  208  may include various interconnected components, including but not limited to circuit boards, processors, memory, sensors, cameras, batteries, wireless (e.g., inductive) charging components, wires, and structural frames and/or supports. Example arrangements and techniques for assembling these internal device components  208  within an interior volume of a glass enclosure  201  are described herein. 
     Cross-hatching in  FIG. 2 , and in any cross-sectional views herein, is used to identify boundaries, borders, and/or interfaces between various components and/or members. Cross-hatching does not necessarily indicate or suggest that any component or member is formed of or includes any particular material, and different cross-hatching patterns, when applied to different components or members, does not necessarily indicate that those components or members are formed of different materials. For example, different cross-hatching patterns may be applied to two different glass members that are formed of glass having identical compositions. 
       FIG. 3  depicts an example schematic diagram of an electronic device  300 . The electronic device  300  may represent the electronic device  100 , and it may also apply to any electronic device described herein. The device  300  includes one or more processing units  301  that are configured to access a memory  302  having instructions stored thereon. The instructions or computer programs may be configured to perform one or more of the operations or functions described with respect to the device  300 . For example, the instructions may be configured to control or coordinate the operation of one or more displays  308 , one or more touch sensors  303 , one or more force sensors  305 , one or more communication channels  304 , one or more microphones  309 , one or more speakers  310 , one or more cameras  311 , one or more sensors  312 , and/or one or more haptic feedback devices  306 . 
     The processing units  301  of  FIG. 3  may be implemented as any electronic device capable of processing, receiving, or transmitting data or instructions. For example, the processing units  301  may include one or more of: a microprocessor, a central processing unit (CPU), an application-specific integrated circuit (ASIC), a digital signal processor (DSP), or combinations of such devices. As described herein, the term “processor” is meant to encompass a single processor or processing unit, multiple processors, multiple processing units, or other suitably configured computing element or elements. 
     The memory  302  can store electronic data that can be used by the device  300 . For example, a memory can store electrical data or content such as, for example, audio and video files, images, documents and applications, device settings and user preferences, timing and control signals or data for the various modules, data structures or databases, and so on. The memory  302  can be configured as any type of memory. By way of example only, the memory can be implemented as random access memory, read-only memory, Flash memory, removable memory, or other types of storage elements, or combinations of such devices. 
     The touch sensors  303  may detect various types of touch-based inputs and generate signals or data that are able to be accessed using processor instructions. The touch sensors  303  may use any suitable components and may rely on any suitable phenomena to detect physical inputs. For example, the touch sensors  303  may be capacitive touch sensors, resistive touch sensors, acoustic wave sensors, or the like. The touch sensors  303  may include any suitable components for detecting touch-based inputs and generating signals or data that are able to be accessed using processor instructions, including electrodes (e.g., electrode layers), physical components (e.g., substrates, spacing layers, structural supports, compressible elements, etc.) processors, circuitry, firmware, and the like. The touch sensors  303  may be integrated with or otherwise configured to detect touch inputs applied to any portion of the device  300 . For example, the touch sensors  303  may be configured to detect touch inputs applied to any portion of the device  300  that includes a display (and may be integrated with a display). In some cases, as described herein, that may include substantially the entire exterior surface of the device  300 , such as where the device  300  includes a substantially omni-directional display arrangement. More particularly, the touch sensors  303  may be configured to detect touch inputs applied to one or both of the major sides and one, two, three, or four of the peripheral sides of an electronic device (e.g., the device  100 ). The touch sensors  303  may operate in conjunction with the force sensors  305  to generate signals or data in response to touch inputs. 
     The force sensors  305  may detect various types of force-based inputs and generate signals or data that are able to be accessed using processor instructions. The force sensors  305  may use any suitable components and may rely on any suitable phenomena to detect physical inputs. For example, the force sensors  305  may be strain-based sensors, piezoelectric-based sensors, piezoresistive-based sensors, capacitive sensors, resistive sensors, or the like. The force sensors  305  may include any suitable components for detecting force-based inputs and generating signals or data that are able to be accessed using processor instructions, including electrodes (e.g., electrode layers), physical components (e.g., substrates, spacing layers, structural supports, compressible elements, etc.) processors, circuitry, firmware, and the like. The force sensors  305  may be used in conjunction with various input mechanisms to detect various types of inputs. For example, the force sensors  305  may be used to detect presses or other force inputs that satisfy a force threshold (which may represent a more forceful input than is typical for a standard “touch” input) Like the touch sensors  303 , the force sensors  305  may be integrated with or otherwise configured to detect force inputs applied to any portion of the device  300 . For example, the force sensors  305  may be configured to detect force inputs applied to any portion of the device  300  that includes a display (and may be integrated with a display). In some cases, as described herein, that may include substantially the entire exterior surface of the device  300 , such as where the device  300  includes a substantially omni-directional display arrangement. The force sensors  305  may operate in conjunction with the touch sensors  303  to generate signals or data in response to touch- and/or force-based inputs. 
     The device  300  may also include one or more haptic devices  306 . The haptic device  306  may include one or more of a variety of haptic technologies such as, but not necessarily limited to, rotational haptic devices, linear actuators, piezoelectric devices, vibration elements, and so on. In general, the haptic device  306  may be configured to provide punctuated and distinct feedback to a user of the device. More particularly, the haptic device  306  may be adapted to produce a knock or tap sensation and/or a vibration sensation. Such haptic outputs may be provided in response to detection of touch and/or force inputs, and may be imparted to a user through the exterior surface of the device  300  (e.g., via a glass or other surface that acts as a touch- and/or force-sensitive display or surface). 
     The one or more communication channels  304  may include one or more wireless interface(s) that are adapted to provide communication between the processing unit(s)  301  and an external device. In general, the one or more communication channels  304  may be configured to transmit and receive data and/or signals that may be interpreted by instructions executed on the processing units  301 . In some cases, the external device is part of an external communication network that is configured to exchange data with wireless devices. Generally, the wireless interface may include, without limitation, radio frequency, optical, acoustic, and/or magnetic signals and may be configured to operate over a wireless interface or protocol. Example wireless interfaces include radio frequency cellular interfaces, fiber optic interfaces, acoustic interfaces, Bluetooth interfaces, infrared interfaces, USB interfaces, Wi-Fi interfaces, TCP/IP interfaces, network communications interfaces, or any conventional communication interfaces. 
     As shown in  FIG. 3 , the device  300  may include a battery  307  that is used to store and provide power to the other components of the device  300 . The battery  307  may be a rechargeable power supply that is configured to provide power to the device  300  while it is being used by the user. 
     The device  300  may also include one or more displays  308 . As described herein, the displays may be configured to display graphical output any or all of the sides of the device  300 . The one or more displays  308  may be coupled together or otherwise arranged and controlled to provide coordinated graphical outputs. For example, adjacent displays  308  (or, in cases where a single display member is folded, adjacent edges of a single display member) may be configured to appear as a single seamless display region. In such cases, the graphical output of the one or more displays  308  may be coordinated so that each display (or portion thereof) displays a portion of a single graphical output or graphical region. This may produce the appearance of a single, seamless display even when a graphical output extends across a seam between two displays. Further, the displays  308  may be configured so that the device  300  may be used in multiple orientations, as described herein. The displays  308  may use any suitable display technology, including liquid crystal displays (LCD), an organic light emitting diodes (OLED), active-matrix organic light-emitting diode displays (AMOLED), or the like. 
     The device  300  may also provide audio input functionality via one or more microphones  309 . The microphones  309  may capture sound for voice calls, video calls, audio recordings, video recordings, and the like. In cases where the device  300  is configured to be used in multiple orientations, while providing substantially identical functionality regardless of its orientation, the audio input functionality may be provided by multiple microphones  309 . The multiple microphones may be positioned on or in the device  300  so that regardless of how the device is being held, a microphone is positioned in a suitable location to capture audio. For example, a device  300  may include four microphones, each positioned so that if the device  300  is held to a user&#39;s ear in a manner that is traditional for a telephone call, a microphone is positioned near the user&#39;s mouth. As another example, a device may include two microphones, one positioned on each of the shorter peripheral sides, which may also result in a microphone being positioned near a user&#39;s mouth regardless of how the device is held. Example positions for multiple microphones are discussed herein. 
     The device  300  may also provide audio output functionality via one or more speakers  310 . The speakers  310  may produce sound from voice calls, video calls, streaming or local audio content, streaming or local video content, or the like. Similar to the microphones that provide audio input functionality, in cases where the device  300  is configured to be used in multiple orientations while providing substantially identical functionality regardless of its orientation the audio output functionality may be provided by multiple speakers  310 . The multiple microphones may be positioned on or in the device  300  so that regardless of how the device is being held, a speaker is positioned in a suitable location to produce audio for a user. For example, a device  300  may include four speakers, each positioned so that if the device  300  is held to a user&#39;s ear in a manner that is traditional for a telephone call, a speaker is positioned near the user&#39;s ear. As another example, a device may include two speakers, one positioned on each of the shorter peripheral sides, which may also result in a speaker being positioned near a user&#39;s ear regardless of how the device is held. Example positions for multiple speakers are discussed herein. 
     The device  300  may also include one or more cameras  311 . Similar to the audio input and output functionality, multiple cameras  311  may be used so that a camera is suitably positioned regardless of how the device is being held. For example, substantially identical cameras may be positioned on each major side of the device, and optionally two cameras may be positioned on each major side (e.g., one near the traditional “top” of the device and one near the traditional “bottom”). The one or more cameras  311  may capture still or video images that are stored on the device  300 . The one or more cameras  311  may also include cameras or other image sensors for a biometric sensing system (e.g., a face recognition system). 
     The device  300  may also include one or more additional sensors  312  to receive inputs (e.g., from a user or another computer, device, system, network, etc.) or to detect any suitable property or parameter of the device, the environment surrounding the device, people or things interacting with the device (or nearby the device), or the like. For example, a device may include accelerometers, temperature sensors, position/orientation sensors, biometric sensors (e.g., fingerprint sensors, photoplethysmographs, blood-oxygen sensors, blood sugar sensors, or the like), eye-tracking sensors, retinal scanners, humidity sensors, buttons, switches, lid-closure sensors, or the like. Such sensors and/or input devices may be configured and/or positioned to function effectively regardless of the position or orientation in which the device  300  is held, as described above with respect to the speakers  310  and microphones  309 . 
     To the extent that multiple functionalities, operations, and structures described with reference to  FIG. 3  are disclosed as being part of, incorporated into, or performed by the device  300 , it should be understood that various embodiments may omit any or all such described functionalities, operations, and structures. Thus, different embodiments of the device  300  may have some, none, or all of the various capabilities, apparatuses, physical features, modes, and operating parameters discussed herein. 
     As noted above, the display of a device (e.g., the display  116  of the device  100 ) may be functionally (e.g., programmatically) segmented into various display regions, which may correspond to different physically distinct sides, surfaces, or portions of the enclosure (e.g., the enclosure  102 ).  FIGS. 4A-4B  are top and bottom perspective views, respectively, of a device  400 , showing example display regions. (The device  400  may be an embodiment of the device  100  in  FIGS. 1A-1B , and may include or incorporate any or all aspects of that device.) 
     The device  400  includes an enclosure  401 , a first main display region  402 , peripheral display regions  404 - 1  through  404 - 4 , and corner display regions  406 - 1  through  406 - 4 . The device  400  may also include a second main display region  408  ( FIG. 4B ), which may be opposite the first main display region  402 . The display regions in  FIGS. 4A-4B  are shown on the exterior surface of the enclosure  401  (which may be an embodiment of the enclosure  102 ), as the graphical outputs produced by an underlying display (e.g., the display  116 ,  FIGS. 1A-1B ) may be visible through those surfaces of the device  400 . 
     These display regions may generally correspond to the physical sides and corners of the enclosure  401 . For example, each region may be primarily viewable through a portion of the enclosure  401  that is physically identifiable or recognizable as a different side. In some cases, as shown and described in greater detail herein, the boundaries of the display regions may correspond to or follow the actual physical geometry of the enclosure  401 . For example, the first main display region  402  may correspond to a substantially planar segment of a display  416  (which may be an embodiment of the display  116  in  FIGS. 1A-1B ) that underlies a substantially planar first major side of the enclosure  401 , while the peripheral display regions  404  may correspond to curved (or flat) portions of the display  416  that underlie or are adjacent the curved peripheral sides of the enclosure  401 . In some cases, the boundaries of the display regions shown in  FIGS. 4A-4B  may be adjusted or changed (or eliminated) based on the context or operational state of the device, as described herein. Moreover, these display regions may be functional and/or programmatic in nature, and as such may not correspond to any seams, borders, or other physical or visible delineations in the enclosure  401  itself. 
     As noted above, the various display regions may be used to define regions of distinct types of content, such as with the first main display region  402  displaying a graphical output corresponding to a primary graphical user interface, and a peripheral display region (e.g.,  404 - 3 ) displaying a graphical output including affordances and basic device information. Of course, as noted above, these display regions may be combined (e.g., the boundaries between them may be removed or ignored) to produce unified display regions that span multiple sides of the device  400 . 
     The corner display regions  406  may also be functionally distinct from other display regions. For example, the corner display regions  406  may be used to display graphical outputs that provide additional information about the device or any operational aspect or state of the device. In some cases, the corner display regions  406  may display a color from a color gradient (e.g., from green to yellow to red) to signify the battery level or signal strength of the device (or to signify any other suitable value or parameter, such as weather, temperature, remaining time on a timer, or the like). In other cases, the corner display regions  406  may display affordances that may control some aspect of the device (e.g., to answer or terminate a call, change speaker volume, change power or display settings, or the like). 
       FIGS. 4A-4B  illustrate different display regions in a device that resembles a rectangular prism with rounded sides. However, similar concepts may be applied to devices and/or enclosures of other shapes as well.  FIGS. 4C-4E  show example devices of various other shapes and/or configurations, and which may use glass enclosures and displays that are viewable through multiple sides and/or surfaces of the enclosure. 
       FIG. 4C  is a perspective view of a device  420  having a generally cylindrical enclosure  422 . The enclosure  422  may be formed of glass, as described with respect to other enclosures herein, and may be transparent along all or substantially all of the surfaces. Due to the cylindrical shape of the enclosure  422 , the enclosure may not have six separate sides, as may be the case with substantially rectangular enclosures, but instead may have two circular bases  426 ,  430  and a cylindrical wall  428 , all or a subset of which may be transparent or substantially transparent. Thus,  FIG. 4C  illustrates an example device that is transparent on all sides, even though the geometry of the enclosure may be considered to have fewer than six distinct sides. 
     Similar to the device  400 , described above, the device  420  may have a display  424  with display regions that correspond to or are otherwise distinguishable based on the geometry of the enclosure  422 . For example, the device  400  may include a main display region  436  that extends completely or substantially completely around the circumference of the cylindrical wall portion of the device  400 . The device  400  may also include peripheral display regions  434 - 1 ,  434 - 2 , and base display regions  432 - 1 ,  432 - 2 . The different display regions of the device  400  may correspond to distinctive physical features of the enclosure  422 , such as the physically different surface regions defined by the cylindrical wall, the bases, and the curved transition between the cylindrical wall and the bases. Further, as described above, the physical distinctions between the surface regions may reinforce or indicate different functional areas of the device  420 . For example, affordances such as volume controls, ring/mute affordances, WiFi affordances, and the like, may be displayed on one or both of the peripheral display regions  434 - 1 ,  434 - 2 , while the main display region  436  may display a main page of a GUI, and the base display regions  432 - 1 ,  432 - 2  display informational content such as stock tickers, time and date, weather information, and the like. 
       FIG. 4D  is a perspective view of a device  440  having an enclosure  442  in the shape of an elliptic cylinder. The enclosure  442  may be formed of glass, as described with respect to other enclosures herein, and may be transparent along all or substantially all of the surfaces. The enclosure  442  may have two elliptical bases  446 ,  450  and a cylindrical wall  448 , all or a subset of which may be transparent or substantially transparent. 
     Similar to the device  400 , described above, the device  420  may have a display  444  with display regions that correspond to or are otherwise distinguishable based on the geometry of the enclosure  442 . For example, the device  440  may include a main display region  456  that extends completely or substantially completely around the circumference of the cylindrical wall portion of the device  440 . The device  440  may also include peripheral display regions  454 - 1 ,  454 - 2 , and base display regions  452 - 1 ,  452 - 2 . The different display regions of the device  440  may correspond to distinctive physical features of the enclosure  442 , such as the physically different surface regions defined by the cylindrical wall, the elliptical bases, and the curved transition between the cylindrical wall and the elliptical bases. Further, as described above, the physical distinctions between the surface regions may reinforce or indicate different functional areas of the device  440 . For example, affordances such as volume controls, ring/mute affordances, WiFi affordances, and the like, may be displayed on one or both of the peripheral display regions  454 - 1 ,  454 - 2 , while the main display region  456  may display a main page of a GUI, and the base display regions  452 - 1 ,  452 - 2  display informational content such as stock tickers, time and date, weather information, and the like. 
       FIG. 4E  is a perspective view of a device  460  having an enclosure  462  in the shape of an octagonal prism. The enclosure  462  may be formed of glass, as described with respect to other enclosures herein, and may be transparent along all or substantially all of the surfaces. The enclosure  462  may have two octagonal bases  468 ,  470 , and a main wall  472  that includes eight segments or facets, each corresponding to one of the sides of the octagonal bases. Like the other enclosures described herein, all or a subset of the sides and bases may be transparent or substantially transparent. 
     Similar to the device  400 , described above, the device  460  may have a display  464  with display regions that correspond to or are otherwise distinguishable based on the geometry of the enclosure  462 . For example, the display  464  may have a display region corresponding to each facet or segment of the main wall  472 , as well as a display region corresponding to each of the octagonal bases. Accordingly, as described above, the physical distinctions between the various sides and facets of the enclosure  462  may reinforce or indicate different functional areas of the device  460 . For example, affordances such as volume controls, ring/mute affordances, WiFi affordances, and the like, may be displayed on the display regions corresponding to the smaller facets of the main wall  472 , while the display regions corresponding to the larger facets of the main wall  472  may display a main page of a GUI, and the display regions corresponding to the octagonal bases of the enclosure  462  may display informational content such as stock tickers, time and date, weather information, and the like. 
     While  FIGS. 4C-4E  show enclosures having various shapes that differ from the generally rectangular prism shapes shown in other figures, it will be understood that the concepts described with respect to enclosures of one shape may be applied to enclosures of any other shape shown herein. For example, while  FIGS. 6A-9B and 10A-15  include enclosures having substantially cuboid shapes to illustrate techniques of joining glass components together, the same techniques may be applied to join glass components of enclosures of other shapes, such as triangular prisms, cylinders, or any other shape. 
     In  FIGS. 1A-1B , the device  100  is shown without any openings or apertures through the enclosure  102  to allow for speaker outputs, charging ports, physical buttons/switches, or the like. Moreover, these figures show the device  100  without any openings through the display  116  to allow for speaker openings, charging ports, camera lenses, light projectors/flashes, or the like. In such cases, the device  100  may include systems that provide these types of functionalities without requiring openings in the display  116  and/or the enclosure  102 . For example, sound (e.g., for videos, telephone calls, or the like) may be produced by piezoelectric or other acoustic actuators inside the display  116  that transmit sound through the enclosure  102 , optionally using the enclosure  102  as a sound-producing component (e.g., as a speaker diaphragm). The device  100  may also include wireless charging components within (e.g., surrounded by) the interior volume defined by the display  116 , facilitating device charging through the display and the enclosure and obviating the need for charging ports. The display  116  may also include transparent areas (or areas that can be either an active display area or a transparent area) that may be aligned with internal cameras, projectors, flashes, or other optical components to allow such components to receive and/or transmit light through the enclosure  102 . 
     The foregoing figures illustrate several examples of devices in which a glass enclosure provides visibility through all of its sides to a display that displays graphical output through all of the major sides of the enclosure. In some cases, advantages and benefits of glass enclosures may be realized in embodiments where not every side is transparent and associated with a display, however. In some cases, only two, three, four, or five of the sides of the enclosure may be transparent and associated with an underlying display. For example, a device may have transparent first and second major sides (e.g., sides  104 ,  106  in  FIG. 1A , which may correspond to front and back sides of a device) and transparent second, third, and fourth peripheral sides (e.g., sides  110 ,  112 ,  114  in  FIG. 1A ), while the first peripheral side (e.g., side  108  in  FIG. 1A ), which may act as or appear to be the “bottom” of the device, may not have an associated display and/or may not be transparent. As another example, both the first peripheral side  108  (e.g., the “bottom” of the device) and the third peripheral side  112  (e.g., the “top” of the device) may lack an associated display and/or may not be transparent. In such cases, the sides that lack a display or that are not transparent may be used to hide seams between enclosure components and/or incorporate opaque regions (e.g., masks), openings for chargers, speakers, microphones, cameras, or the like. 
     Moreover, while some embodiments of the described devices are capable of use in multiple different orientations (e.g., allowing either major side to act as the front, and either of the short sides of the device to act as the top), other configurations may maintain some fixed cardinality. For example, in some cases, a speaker is located proximate one end of the device (e.g., a “top”) and a microphone is located proximate an opposite end (e.g., a “bottom”), similar to conventional telephones. In such cases, certain functions (e.g., voice communications in which a device is held adjacent a user&#39;s head) may require that the device be held or used in a certain orientation. 
     As noted above, a device with transparent sides may use an enclosure formed entirely or partially of glass (or other suitable materials, as described below). For a device with multiple sides formed of transparent glass (e.g., three, four, five, or six sides), assembling an enclosure by attaching distinct glass panels together may not produce an enclosure of suitable strength and/or transparency. For example, the enclosure may require internal structures to ensure proper alignment between the various panels and to join the panels. Moreover, the seams between adjacent panels may interfere with the visibility of the underlying displays. In order to avoid these and other potential drawbacks, a glass enclosure may be formed using various techniques that may reduce or minimize the number or visibility of seams or joints between glass components while producing a suitably strong enclosure to protect the internal components of the electronic device and otherwise be sufficiently resistant to breakage or damage. 
     The glass enclosures described herein may be formed of any suitable glass, including soda lime glass, aluminosilicate glass, borosilicate glass, chemically strengthened glass, or any other suitable type of glass. Other transparent materials may be used to form enclosures that may be used with devices as described herein, such as polymers, sapphire, transparent ceramics, fused quartz, or the like. 
       FIGS. 5A and 5B  are front and perspective views, respectively, of a glass enclosure  500  for an electronic device. The glass enclosure  500  may define substantially all of the exterior surfaces of the electronic device. For example, the glass enclosure  500  is shown as defining six sides, corresponding to the first and second major sides and the four peripheral sides, as described above with respect to  FIG. 1A . The glass enclosure  500  may define an interior volume in which components of the electronic device are received (e.g., processors, memory, display(s), battery, sensors, cameras, circuitry, and the like). For clarity and ease of reference, the glass enclosure  500  is shown in a simplified shape as compared to the enclosures shown in  FIGS. 1A-1B . However, it will be understood that the shape of the glass enclosure  500  is merely for illustration, and that the glass enclosure  500  may represent other enclosure shapes and configurations, including enclosures with continuous contoured corners (e.g., including the corners  504  between two peripheral sides, as well as the corners  506  between a major side and a peripheral side). 
       FIGS. 6A-15  illustrate various ways in which a six-sided glass enclosure  500  may be formed. These configurations may help produce enclosures that are particularly suited to provide multiple transparent side walls through which displays can be viewed and interacted with. For example, these configurations may position seams or joints between various glass members or components in locations where they are less visible or otherwise less likely to interfere with viewing and interacting with an underlying display. Moreover, these configurations may aid in the assembly of components within the interior volume of the enclosure by forming parting lines and/or openings in suitable locations to allow for components to be inserted in the enclosure during or after the enclosures are assembled or bonded. 
     In  FIGS. 6A-15 , where two or more glass components are joined, they may be attached to one another in any suitable manner. For example, glass components may be joined together using glass frit bonding, adhesive, epoxy, fusion bonding (e.g., laser welding), ultrasonic welding, or any other suitable joining technique or medium. In some cases, the glass components may have interlocks or other engagement structures that mechanically engage to retain components together. Such engagement structures may be used instead of or in addition to other joining techniques (e.g., frit bonding, fusion bonding, adhesive bonding, and so on). Several examples of joints between different glass components are described herein with respect to  FIGS. 6A-15 . As noted, any of these techniques may be used singly or in various combinations to join components shown in the following figures. For example, in some cases additive manufacturing (e.g., 3-D printing) may be 
     In some cases, instead of joining two or more pre-formed enclosure components to form the enclosure, the enclosure material may be formed using additive manufacturing and/or three dimensional printing processes, such as selective laser sintering, stereolithogrophy, or the like. In some cases, the enclosure may be formed around internal components of a device. For example, internal electrical components may positioned in an additive manufacturing apparatus, and all or part of an enclosure may formed around the electrical components, thereby at least partially enclosing the electrical components within the enclosure. Subsequent processing steps may then be performed with respect to the device, including polishing, lapping, or otherwise processing the resultant enclosure, forming openings in the enclosure, and the like. 
     Any of the techniques described herein for forming enclosures may be used singly or in various combinations. For example, additive manufacturing (e.g., 3-D printing) may be used to form an entire seamless enclosure. In other cases, additive manufacturing may be used to form two or more enclosure components that may subsequently be joined together (e.g., with frit bonding, adhesive, or the like) to form the enclosure. Other techniques are also contemplated. 
       FIGS. 6A-6B  show perspective views of an enclosure  600 , with  FIG. 6A  showing the enclosure  600  in an unassembled state, and  FIG. 6B  showing the enclosure  600  in an assembled state. The enclosure  600  includes a first glass member  602  and a second glass member  604 , either or both of which may be monolithic glass members. The first glass member  602  defines a first major side  606  (e.g., a transparent front portion) and substantially all of the peripheral sides  608  of the enclosure  600 . The first glass member  602  thus defines substantially all of five sides of both the exterior surface of the enclosure  600  and of an interior cavity or volume in which internal components of a device may be positioned. 
     The second glass member  604  defines a second major side  610  (e.g., a transparent back portion) of the enclosure  600 . When the first glass member  602  and the second glass member  604  are joined, the sides  605  of the second glass member  604  may define a portion of the peripheral sides  608  of the enclosure  600 . As shown in  FIG. 6B , when joined, a seam  612  may be formed between the first glass member  602  and the second glass member  604 . Because the first glass member  602  defines substantially all of the peripheral sides of the enclosure (e.g., substantially all of each peripheral side, extending from the first major side almost the entire way to the second major side), the seam  612  may be positioned away from the middle of the peripheral sides. This configuration may place the seam  612  out of the main viewing area of any displays that may be viewable through the peripheral sides. In some cases, as described with respect to  FIG. 21C , the joining regions of the first and second members  602 ,  604  may be mitered or angled, so that the seam  612  is not visible on the peripheral sides, but rather is positioned directly on the corner between the peripheral sides  608  and the second major side  610  of the enclosure  600 . As noted above, the first and second glass members  602 ,  604  may be joined using any suitable technique, including techniques that hide or otherwise minimize the visibility of the seam  612 . 
       FIG. 6C  is a detail view of a peripheral side of the enclosure  600 , corresponding to the area  614  in  FIG. 6B . As shown in  FIG. 6C , the seam  612  is located closer to the second major side  610  than the first major side  606 .  FIG. 6D  is a detail view, corresponding to the area  614 , of another example embodiment of the enclosure  600 , in which a seam  616  is located closer to the first major side  606  than the second major side  610 .  FIG. 6E  is a detail view, corresponding to the area  614 , of another example embodiment of the enclosure  600 , in which a seam  618  is substantially equidistant from the first major side  606  and the second major side  610 . The positioning of the seam may be determined based on any suitable factors or considerations, such as positioning displays and/or display regions, locations of seams in the underlying displays, and the like. As noted above and described in greater detail herein, techniques for hiding or reducing the visibility of a seam (e.g., the seams  612 ,  616 ,  618 ) may be used, including contoured or angled joint surfaces, transparent bonding materials, post-bonding finishing and/or polishing, or the like. 
       FIGS. 7A-7B  show perspective views of an enclosure  700 , with  FIG. 7A  showing the enclosure  700  in an unassembled state, and  FIG. 7B  showing the enclosure  700  in an assembled state. The enclosure  700  includes a first glass member  702  and a second glass member  704  (either or both of which may be monolithic glass members). The first glass member  702  defines a first major side  706  and includes walls or portions  703  that define substantially all of two substantially parallel peripheral sides (sides  710 ,  FIG. 7B ). The first glass member  702  may define none of or only a small portion of the other two peripheral sides (sides  714 ,  FIG. 7B ), thus defining notches  707  that receive corresponding walls  711  of the second glass member  704 . The walls  711  of the second glass member  704  thus define substantially all of the remaining peripheral sides  714  ( FIG. 7B ) of the assembled enclosure  700 . 
     The shapes of the first and second glass members  702 ,  704 , and in particular the configuration in which each member defines substantially all of two opposite side walls, results in a seam  712  that does not follow a single linear path. Moreover, on each side of the enclosure  700 , the seam  712  is positioned proximate to a corner of the enclosure  700  rather than extending through a middle of the surface or otherwise being positioned along a surface or wall through which a display is configured to be viewed. Furthermore, both the first and the second glass members  702 ,  704  each define substantially all of three adjacent of the sides of the enclosure  700 . Thus, a single, unbroken glass component (e.g., the first glass member  702 ) may define the first major side  706  and the two peripheral sides  710  on opposite sides of the first major side  706 . In embodiments where displays are viewable through each of these sides, the continuous configuration of the sides (e.g., having no seams) may help provide clear, undistorted, uninterrupted viewing and/or interaction surfaces. 
     The enclosure  700  may be used in embodiments where displays are viewable through only three sides of the enclosure  700  (e.g., a front side and two peripheral sides, corresponding to the sides that are defined by a monolithic piece of glass), as all of the seams may be placed outside of the viewable regions of the front- and side-facing displays. Moreover, because each of the glass members defines at least two opposite (optionally parallel) peripheral walls extending from the main portion of the glass member, both glass members may be stiffer and/or stronger than a simple, substantially featureless sheet. 
       FIGS. 8A-8B  show perspective views of an enclosure  800 , with  FIG. 8A  showing the enclosure  800  in an unassembled state, and  FIG. 8B  showing the enclosure  800  in an assembled state. The enclosure  800  includes a first glass member  802  and a second glass member  804  (either or both of which may be monolithic). The first glass member  802  may be a substantially flat and/or featureless sheet that forms a portion of a first major side  806  ( FIG. 8B ). The second glass member  804  defines a second major side  808  and walls that define the peripheral sides  810  of the enclosure  800 . The second glass member  804  also defines a portion  807  of the first major side  806 . Thus, the portion  807  of the second glass member  804  may define an opening  809  that is configured to receive the first glass member  802  (e.g., the first glass member  802  may be positioned in the opening  809  and secured to the second glass member  804 ). 
     As shown in  FIG. 8B , once assembled together, the enclosure  800  may have a seam  812  where the first and second glass members  802 ,  804  were joined together. Because the seam  812  may be inset from the corners of the first major side  806 , the first major side may not be associated with an underlying display, and instead the second major side  808 , defined by the second glass member  804 , may be used as the primary interface and display surface of a device that uses the enclosure  800 . In other cases, a display may be associated with a portion of the first major side  806  that does not include the seam, such as a peripheral area or a central area. In yet other cases, a first display may extend around the interior surface of the enclosure  800  and is visible through the first main side  806 , the peripheral sides  810 , and the peripheral portion  807  of the second glass member  804 , while a second display having substantially the same size and shape of the first glass member  802  is beneath and visible through the second glass member  802 . 
       FIGS. 9A and 9B  show perspective views of an enclosure  900 , with  FIG. 9A  showing the enclosure  900  in an unassembled state, and  FIG. 9B  showing the enclosure  900  in an assembled state. The enclosure  900  includes a first glass member  902  and a second glass member  904  (either or both of which may be monolithic). The first glass member  902  may define a wall  906  that forms a portion (and in some cases substantially all) of a first major side  926  ( FIG. 9B ) and an opposite wall that defines a portion of a second major side opposite (e.g., parallel to) the first major side  926 . The first glass member  902  may also include walls  909  that form a portion of two peripheral sides  920  ( FIG. 9B ), and a wall  903  that defines all of another peripheral side  921  ( FIG. 9B ) of the enclosure  900 . The second glass member  904  may have a similar shape as the first glass member  902 , and may include walls  905  that form another portion of two peripheral sides  920  ( FIG. 9B ), and a wall  901  that defines all of another peripheral side  921  ( FIG. 9B ) of the enclosure  900 . Both the first and second glass members  902 ,  904  may define a portion of an interior cavity or volume in which components of an electronic device may be positioned. 
     The first and second glass members  902 ,  904  may be coupled to one another to form the complete enclosure  900 , which may produce a seam  922  ( FIG. 9B ) that extends around the enclosure  900 . In some cases, displays within the enclosure  900  may be positioned so that that seam does not extend over active display regions. For example, a device using the enclosure  900  may include displays that are visible through only the walls of the first glass member  902 , and thus the seam  922  may not be visible or may not interfere with viewing the displays. In such cases, some or all of the second glass member  904  may be masked, painted, coated, or otherwise made opaque or translucent to cover or occlude underlying components, such as charging components, communication ports, wires, flex circuits, audio ports, cameras, projectors, sensors, or the like. 
     As shown in  FIG. 9A , the first and second glass members  902 ,  904  each define a certain proportion of the outer surface of the enclosure  900 . The sizes of these members in  FIG. 9A , however, are merely exemplary, and they may have other dimensions and thus make up different proportions of the outer surface of the enclosure  900 . For example, the first and second glass members  902 ,  904  may each define substantially half of the outer surface of the enclosure  900 , resulting in a seam  922  that substantially bisects the enclosure  900 . Other configurations are also contemplated. 
     As shown in  FIG. 9A , the first and second glass members  902 ,  904  may be coupled to one another along a butt joint, where substantially perpendicular faces of glass are placed in contact or in proximity to one another and bonded, adhered, fused, or otherwise secured to one another. Other types of joints for attaching the first and second glass members  902 ,  904  are also contemplated, as described with respect to  FIGS. 19A-20B . 
       FIGS. 9C-9D  show perspective views of an enclosure  930 , with  FIG. 9C  showing the enclosure  930  in an unassembled state, and  FIG. 9D  showing the enclosure  930  in an assembled state. While the shape of the enclosure  900  is or resembles a rectangular prism, the enclosure  930  is substantially cylindrical, and may correspond to or be an embodiment of the enclosure  422  of  FIG. 4C . The enclosure  930  includes a first glass member  932  and a second glass member  934 . The first glass member  932  may be substantially cylindrical and may define all or substantially all of a cylindrical wall  933  and a base  935  of the enclosure  930 . The second glass member  934  may form define another base  937  of the enclosure, and may define part of the cylindrical wall  933 . Both the first and second glass members  932 ,  934  may define a portion of an interior cavity or volume in which components of an electronic device may be positioned. 
     The first and second glass members  932 ,  934  may be coupled to one another to form the complete enclosure  930 , which may produce a seam  936  ( FIG. 9D ) that extends around the enclosure  930 . As shown in  FIG. 9C , the first and second glass members  932 ,  934  each define a certain proportion of the outer surface of the enclosure  930 . The sizes of these members in  FIG. 9C , however, are merely exemplary, and they may have other dimensions and thus make up different proportions of the outer surface of the enclosure  930 . For example, the first and second glass members  932 ,  934  may each define substantially half of the outer surface of the enclosure  930 , resulting in a seam  936  that substantially bisects the enclosure  930 . Other configurations are also contemplated. 
     Similar to the discussion with respect to  FIG. 9A , the first and second glass members  932 ,  934  may be coupled to one another along a butt joint, where substantially perpendicular faces of glass are placed in contact or in proximity to one another and bonded, adhered, fused, or otherwise secured to one another. Other types of joints for attaching the first and second glass members  932 ,  934  are also contemplated, as described with respect to  FIGS. 19A-20B . 
       FIGS. 10A-10B  show perspective views of an enclosure  1000 , with  FIG. 10A  showing the enclosure  1000  in an unassembled state, and  FIG. 10B  showing the enclosure  1000  in an assembled state. The enclosure  1000  includes a first glass member  1002  and a second glass member  1004 , which may be substantially similar to the first and second glass members  902 ,  904  in  FIGS. 9A-9B . However, the second glass member  1004  may include a ledge  1016  (which may be a segment of glass having a reduced thickness relative to an adjacent portion of the second glass member  1004 ) that is received within the first glass member  1002 . The first glass member  1002  may define a reduced thickness region  1018  around the opening of an aperture  1017 , and the ledge  1016  may be received on and/or contact the reduced thickness region  1018 . Once assembled, the first and second glass members  1002 ,  1004  may be joined using any suitable technique to define an enclosure that appears substantially similar to the enclosure shown in  FIGS. 9A-9B . Moreover, the first and second glass members  1002 ,  1004  may define substantially continuous and/or planar exterior and interior surfaces in the regions of the ledge  1016  and the reduced thickness region  1018 . More particularly, the ledge  1016  and reduced thickness region  1018  may be configured and sized so that, when assembled, the wall thickness of the first and second glass members  1002 ,  1004  in the area of the seam  1022  is substantially constant and there is no ledge or discontinuity on the inner and/or exterior surfaces where the two members meet. 
       FIGS. 11A-11B  show perspective views of an enclosure  1100 , with  FIG. 11A  showing the enclosure  1100  in an unassembled state, and  FIG. 11B  showing the enclosure  1100  in an assembled state. The enclosure  1100  includes a first glass member  1102  and a second glass member  1104  (either or both of which may be monolithic). The first glass member  1102  may define a first major side  1101  and a second major side (opposite and/or parallel to the first major side), as well as all or substantially all of three peripheral sides  1105  of the enclosure  1100 . The first glass member  1102  may define an opening  1103  at an end of the enclosure, and a second glass member  1104  may be coupled to the first glass member  1102  to close or cover the opening  1103  (and optionally seal the enclosure) and define a fourth peripheral side  1107  of the enclosure  1100 . 
     The second glass member  1104  may be inserted into the opening  1103  such that end portions of the first glass member  1102  define part of the fourth peripheral side  1107  (as shown in  FIG. 11B ), and a seam  1112  is positioned on the fourth peripheral side  1107 . In other embodiments, it may abut the first glass member  1102  such that sides of the second glass member  1104  define portions of the first and second major sides and the peripheral sides  1105  of the enclosure. In some cases, the first and/or second glass members  1102 ,  1104  may be configured so that a seam is positioned on or along a rounded corner or region between the sides defined by the first glass member  1102  and the fourth peripheral side  1107  defined by the second glass member  1104 . The enclosure  1100  may be used in embodiments where there is no display visible through the peripheral side  1107 . In such cases, the seam between the first and second glass members  1102 ,  1104  may have little or no effect on the visibility of the displays within the enclosure  1100 , as the seam may not overlie or otherwise interrupt a viewing surface. Moreover, as noted above, the second glass member  1104  (and optionally part of the first glass member  1102  proximate the second glass member  1104 ) may be masked, painted, coated, or otherwise made opaque or translucent to cover or occlude underlying components, such as charging components, communication ports, wires, flex circuits, audio ports, cameras, projectors, sensors, or the like. 
       FIGS. 12A-12B  show perspective views of an enclosure  1200 , with  FIG. 12A  showing the enclosure  1200  in an unassembled state, and  FIG. 12B  showing the enclosure  1200  in an assembled state. The enclosure  1200  includes a first glass member  1202  and a second glass member  1204  (either or both of which may be monolithic). The first glass member  1202  may define a first major side  1201  and a second major side (opposite and/or parallel to the first major side), as well as all or substantially all of three peripheral sides  1205  of the enclosure  1200 . The first glass member  1202  may define an opening  1203  at an end of the enclosure, and a second glass member  1204  may be coupled to the first glass member  1202  to close or cover the opening  1203  (and optionally seal the enclosure) and define a fourth peripheral side  1207  of the enclosure  1200 . The enclosure  1200  is similar to the enclosure  1100 , but instead of the opening being positioned along a short side of the enclosure (as in the enclosure  1100 ), the enclosure  1200  has its opening positioned along a long side of the enclosure  1200 . This configuration may provide a larger opening for inserting electronic device components, such as displays, display assemblies, batteries, processors, and the like. 
     Similar to the description relating to the enclosure  1100 , the second glass member  1204  may be inserted into the opening  1203  such that end portions of the first glass member  1202  define part of the fourth peripheral side  1207  (as shown in  FIG. 12B ), and a seam  1212  is positioned on the fourth peripheral side  1207 . In other embodiments, it may abut the first glass member  1202  such that sides of the second glass member  1204  define portions of the first and second major sides and the peripheral sides  1205  of the enclosure. In some cases, the first and/or second glass members  1202 ,  1204  may be configured so that a seam is positioned on or along a rounded corner or region between the sides defined by the first glass member  1202  and the fourth peripheral side  1207  defined by the second glass member  1204 . 
       FIGS. 10A-12B  describe enclosures in which a first glass member that defines the major sides of the enclosure has one open end, and a second glass member is attached to the first glass member to define one of the peripheral sides of the enclosure. In some cases, multiple ends of the first glass member are open, and multiple second glass members may be attached to the first glass member to enclose the enclosure and define the peripheral sides of the enclosure. For example, the first glass member may resemble a tube or other hollow structure with two opposing open ends. Two second glass members (which may be similar or identical the single-instances of the second glass members shown in  FIGS. 10A-12B ) may be attached to the first glass member to define opposite peripheral sides of the enclosure. 
       FIGS. 13A-13B  show perspective views of an enclosure  1300 , with  FIG. 13A  showing the enclosure  1300  in an unassembled state, and  FIG. 13B  showing the enclosure  1300  in an assembled state. The enclosure  1300  includes a first glass member  1302  and a second glass member  1304  (either or both of which may be monolithic). The first glass member  1302  defines a first major side  1306  and includes walls or portions  1303  that define substantially all of two adjacent peripheral sides (sides  1310 ,  FIG. 13B ). The first glass member  1302  may define none of or only a small portion of the other two peripheral sides (sides  1314 ,  FIG. 13B ). The walls  1311  of the second glass member  1304  thus define substantially all of the remaining peripheral sides  1314  ( FIG. 13B ) of the assembled enclosure  1300 . 
     Similar to the enclosure  800  described with reference to  FIGS. 8A-8B , the shapes of the first and second glass members  1302 ,  1304  result in a seam  1312  ( FIG. 13B ) that does not follow a single linear path. Moreover, on each side of the enclosure  1300 , the seam  1312  is positioned proximate to a corner of the enclosure  1300  rather than extending through a middle of the surface or otherwise being positioned along a surface or wall through which a display is configured to be viewed. 
       FIGS. 14A-14B  show perspective views of an enclosure  1400 , with  FIG. 14A  showing the enclosure  1400  in an unassembled state, and  FIG. 14B  showing the enclosure  1400  in an assembled state. The enclosure  1400  includes a first glass member  1402  and a second glass member  1404  (either or both of which may be monolithic). The first glass member  1402  defines a first major side  1406  and a second major side opposite the first major side  1406 , and includes walls defining all of at least three peripheral sides  1410 , and a wall  1405  defining a portion of a fourth peripheral side  1414  ( FIG. 14B ). The wall  1405  defines a slot or opening  1407  through which components of the electronic device may be introduced into the interior volume defined (at least partially) by the first glass member  1402 . 
     The second glass member  1404  may be received in the opening  1407  or otherwise attached to the first glass member  1402  to cover the opening  1407  and, with the wall  1405 , fully define the fourth peripheral wall  1414  of the enclosure  1400 . As shown, the wall  1405  has a contoured or rounded exterior surface. The second glass member  1404  may have a contoured or rounded exterior surface that substantially matches the shape of the wall  1405 . Accordingly the wall  1405  and the second glass member  1404  may define a single substantially continuous curved surface or profile along the fourth peripheral wall  1414 . 
       FIG. 15  shows a perspective view of an example enclosure  1500 . The enclosure  1500  includes a glass member  1502  (e.g., a monolithic or unitary glass member) that defines substantially all sides and exterior surfaces of the enclosure  1500 . The glass member  1502  defines an opening or slot  1506  through one of its peripheral sides. Whereas the slot or opening  1407  in  FIGS. 14A-14B  is positioned along a long side of the enclosure  1400  and extending substantially the entire length of the side (e.g., 80%, 90%, 95%, or 99% of the length of the peripheral side  1414 ), the slot  1506  is substantially smaller than the peripheral side in which it is positioned. For example, the slot  1506  may be less than 50% of the length of the peripheral side in which it is positioned (optionally less than 40%, less than 30%, or less than 20%). The slot  1506  may be selected based on the size of the largest component to be inserted into the glass member  1502 , thus allowing device components to be positioned in the interior volume of the glass member  1502 . As described herein, components may be folded, compressed, or otherwise deformed while being passed through the slot  1506 , and then unfolded, uncompressed, or otherwise expanded after being positioned within the interior volume of the glass member  1502 . 
     The enclosure  1500  also includes a cap or plug  1504  that is inserted in the slot  1506  or otherwise coupled to the glass member  1502  to occlude or otherwise close the slot  1506  (and optionally seal the enclosure  1500 ). The plug  1504  may define a portion of the peripheral side of the enclosure  1500  in which the slot  1506  is positioned. The plug  1504  may be any suitable material, including glass, rubber, polymer, metal, or the like. In some cases, the plug  1504  may include or accommodate electrical contacts to act as a charging and/or communication interface for a device that uses the enclosure  1500 . The plug  1504  may also define an opening to allow access to a charging and/or communication port, a speaker, a microphone, or any other component that may be positioned within the enclosure  1500 . The plug  1504  may be securely or permanently attached to the enclosure  1500  (e.g., via adhesive, fusion bonding, mechanical interlocks, etc.), or it may be removable. Where the plug  1504  is removable, it may cover or be aligned with a receptacle for a subscriber identity module (SIM) card, a memory card (e.g., a secure digital (SD) card), or the like. The plug  1504  may thus be removed (without damaging the plug  1504  and/or the enclosure  1500 ) to allow cards or other components to be inserted into and/or removed from the receptacle within the enclosure  1500 . 
       FIG. 16A  shows a perspective view of an example enclosure  1600 . The enclosure  1600  may include a first glass member  1602  and a second glass member  1604 . The first glass member  1602  defines a first major side  1606  and a portion of each of the peripheral sides  1608  of the enclosure  1600 . The second glass member  1604  defines a second major side  1610  and another portion of each of the peripheral sides  1608 . The enclosure  1600  also includes an intermediate member  1612  between the first and second glass members  1602 ,  1604 . The intermediate member  1612  may be metal, plastic, glass, or another suitable material, and may serve as a structural member of the device and may facilitate bonding between the first and second glass members  1602 ,  1604 . Alternatively, the intermediate member may be cosmetic, and may contribute little or no structural strength or rigidity to the enclosure. The first and second glass members  1602 ,  1604  may be secured to the intermediate member  1612  in any suitable way, including mechanical interlocks, adhesives, epoxies, ultrasonic welding, frit bonding, or the like. 
     The first and second glass members  1602 ,  1604  and the intermediate member  1612  thus cooperate to define the peripheral sides  1608  of the enclosure  1600 , and each of the first and second glass members  1602 ,  1604  at least partially defines an interior cavity (e.g., defining a base or bottom surface, corresponding to the major side, and four walls extending from the base or bottom surface around a periphery of the base). 
       FIGS. 16B-16C  show partial cross-sectional views of various embodiments of devices using enclosures such as the enclosure  1600  of  FIG. 16A  (e.g., viewed along line D-D in  FIG. 16A ). More particularly,  FIGS. 16B-16C  show example configurations of glass members and intermediate members that define an enclosure, and display members that may be positioned within an interior volume of the enclosure.  FIG. 16B , for example, shows how a display formed of two display members  1618 ,  1620  may be positioned relative to first and second glass members  1616 ,  1622  (which may be substantially similar to the first and second glass members  1602 ,  1604 ,  FIG. 16A ). In particular, a first display member  1618  may substantially conform to or otherwise have a similar shape as the interior surface of the first glass member  1616 . Similarly, a second display member  1620  may substantially conform to or otherwise have a similar shape as the interior surface of the second glass member  1622 . Accordingly, the display members  1618 ,  1620  each produce graphical outputs that may be visible through a major side and a portion of the peripheral sides of the enclosure. The first and second display members  1618 ,  1620  may or may not extend past an intermediate member  1614  (which may be substantially similar to the intermediate member  1612 ,  FIG. 16A ), but in any event the intermediate member  1614  may occlude or cover any gaps or seams between the display members  1618 ,  1620 . 
       FIG. 16C  shows another example embodiment in which a single display member  1624  (which may be defined by a single layer or multiple layers) may be positioned within the enclosure. Apart from the display member  1624 , the embodiment shown in  FIG. 16C  may include the same enclosure components as the embodiment shown in  FIG. 16B . The single display member  1624  may be a single substrate (or a stack of substrates) that is folded or otherwise formed to produce graphical outputs that are visible through at least the first and second major sides and the peripheral sides of the enclosure. Example display members having such configurations are described herein. While a portion of the display member  1624  may be positioned behind the intermediate member  1614 , the intermediate member  1614  may block or occlude the graphical output displayed on that portion of the display member  1624 . 
       FIG. 17A  shows a perspective view of an example enclosure  1700 . The enclosure  1700  may include a first glass member  1702  and a second glass member  1704 . The first glass member  1702  defines a first major side  1706  and a portion of each of the peripheral sides  1708  of the enclosure  1700 . The second glass member  1704  defines a second major side  1710  and another portion of each of the peripheral sides  1708 . The enclosure  1700  also includes an intermediate member  1712  between the first and second glass members  1702 ,  1704 . The intermediate member  1712  may be metal, plastic, glass, or another suitable material, and may serve as a structural member of the device and may facilitate bonding between the first and second glass members  1702 ,  1704 . Alternatively, the intermediate member may be cosmetic, and may contribute little or no structural strength or rigidity to the enclosure. The first and second glass members  1702 ,  1704  may be secured to the intermediate member  1712  in any suitable way, including mechanical interlocks, adhesives, epoxies, ultrasonic welding, frit bonding, or the like. 
     The first and second glass members  1702 ,  1704  and the intermediate member  1712  thus cooperate to define the peripheral sides  1708  of the enclosure  1700 , and each of the first and second glass members  1702 ,  1704  at least partially defines an interior cavity (e.g., defining a base or bottom surface, corresponding to the major side, and four walls extending from the base or bottom surface around a periphery of the base). 
     The enclosure  1700  may be similar to the enclosure  1600  in  FIG. 16A , except that the intermediate member  1712  is not positioned along a middle of the peripheral sides. Rather, the intermediate member  1712  is offset from the middle (or centerline) of the peripheral sides. For example, as shown in  FIG. 17A , the first glass member  170  may define substantially all of each peripheral side  1708  of the enclosure (or at least one of the peripheral sides), and the second glass member  1704  may define a smaller portion of the peripheral sides of the enclosure (e.g., less than half, and optionally none). While  FIG. 17A  shows the intermediate member  1712  closer to the back of the enclosure  1700  (e.g., the second major side  1710 ), other embodiments may have the intermediate member  1713  positioned closer to the front of the enclosure  1700  (e.g., closer to the first major side  1706 ). 
       FIGS. 17B-17D  show partial cross-sectional views of various embodiments of devices using enclosures such as the enclosure  1700  of  FIG. 16A  (e.g., viewed along line D′-D′ in  FIG. 17A ). More particularly,  FIGS. 17B-17D  show example configurations of glass members and intermediate members that define an enclosure, and display members that may be positioned within an interior volume of the enclosure.  FIG. 17B , for example, shows how a display formed of two display members  1726 ,  1728  may be positioned relative to first and second glass members  1720 ,  1722  (which may be substantially similar to the first and second glass members  1702 ,  1704 ,  FIG. 17A ). In particular, a first display member  1726  may substantially conform to or otherwise have a similar shape as the interior surface of the first glass member  1720 . Similarly, a second display member  1728  may substantially conform to or otherwise have a similar shape as the interior surface of the second glass member  1722 . Accordingly, the display members  1726 ,  1728  each produce graphical outputs that may be visible through a major side and a portion of the peripheral sides of the enclosure. The first and second display members  1726 ,  1728  may or may not extend past an intermediate member  1724  (which may be substantially similar to the intermediate member  1712 ,  FIG. 17A ), but in any event the intermediate member  1724  may occlude or cover any gaps or seams between the display members  1726 ,  1728 . In some cases, the second display member  1728  may be omitted, and/or any portion of either of the display members  1726 ,  1728  that is visible through the peripheral sides of the enclosure may be omitted. 
       FIG. 17B  also further illustrates how the first glass member  1720  may define a greater amount of the peripheral sides of the enclosure than the second glass member  1722 , and how the intermediate member  1724  may be offset from a centerline of the enclosure. For example, the second glass member  1722  may define less than half, and optionally none of the peripheral sides. 
       FIG. 17C  shows another example embodiment in which a first glass member  1732  defines a greater amount of the peripheral sides of the enclosure than a second glass member  1734 . In this example, the portions of the first and second glass members  1732 ,  1734  that define the peripheral sides of the enclosure may have a different (e.g., larger) thickness than other portions of the first and second glass members  1732 ,  1734  (e.g., than the portions defining the first and second major surfaces of the enclosure). The intermediate member  1730  (which may be otherwise similar to the intermediate element  1712 ,  FIG. 17A ) may also have a larger dimension (e.g., a thickness) to accommodate the larger portions of the first and second glass members  1732 ,  1734 . Like the embodiment shown in  FIG. 17B , first and second display members  1736 ,  1738  may substantially conform to or otherwise have a similar shape as the interior surfaces of the first and second glass members  1732 ,  1734 , and may be visible through the peripheral sides. As noted above, in some cases the second display member  1738  may be omitted, as may be the portion(s) of the display member(s) that are visible through the peripheral sides of the device. 
       FIG. 17D  shows another example embodiment in which a first glass member  1742  defines a greater amount of the peripheral sides of the enclosure than a second glass member  1744 . In this example, the portions of the first and second glass members  1742 ,  1744  that define the peripheral sides of the enclosure may have a different thickness (e.g., smaller) than other portions of the first and second glass members  1742 ,  1744  (e.g., than the portions defining the first and second major surfaces of the enclosure). More particularly, as shown, the peripheral sides of the enclosure are thinner than a portion of the first glass member  1742  that defines a first major side of the enclosure. The embodiment shown in  FIG. 17D  may also include an intermediate member  1740 , which may be the same as or similar to the intermediate member  1712  in  FIG. 17A  (or any other intermediate member described herein). 
     Like the embodiment shown in  FIG. 17B , first and second display members  1746 ,  1748  may substantially conform to or otherwise have a similar shape as the interior surfaces of the first and second glass members  1742 ,  1744 , and may be visible through the peripheral sides. As noted above, in some cases the second display member  1748  may be omitted, as may be the portion(s) of the display member(s) that are visible through the peripheral sides of the device. 
     The foregoing enclosures include examples in which multiple enclosure members (e.g., glass enclosure members) may be attached together to define an enclosure that may have substantially all of its exterior surfaces of glass. Each enclosure described above defines an interior volume or cavity in which electronic device components may be positioned (e.g., displays, batteries, processors, memory, circuit boards, sensors, microphones, cameras, projectors, and the like). The multi-piece construction of these enclosures may facilitate assembly and manufacture of devices, as components may be positioned in or on a first of the glass members prior to another glass member being attached to the first glass member. Once the multiple glass members are attached to one another, the enclosure may completely or substantially completely enclose the electronic device components and may produce an enclosure in which substantially all of the exterior surfaces are glass. 
     Electronic devices, such as smartphones, tablet computers, and other small and/or handheld devices, may be subject to impacts, drops, and other potentially damaging events. Accordingly, the enclosures described herein may be configured with variable thickness walls to help increase the strength, durability, crack resistance, or other physical properties, in certain areas of the enclosures. The variable thickness walls may also be used to produce different regions that have different flexibilities or stiffnesses for user-interface purposes. For example, the first and second major sides of an enclosure may be thinner than the corner regions to allow the first and second major sides to flex more when a user touches or presses on those sides (e.g., when interacting with a touch- and/or force-sensitive display), thereby providing a tactile feel that is similar to or evokes the sensation of pushing a button. Similarly, some or all of the peripheral sides of an enclosure may be thinner than the corner regions of the enclosure to allow greater flex along the peripheral sides. Flexible peripheral sides may provide a tactile feedback or sensations to a user when they select (e.g., press) an affordance that is displayed on a side-visible display (e.g., a volume button similar to the buttons shown in  FIG. 1A ). 
       FIG. 18  shows a cross-sectional view of an example enclosure  1800 , viewed along line C-C in  FIG. 5B , in which the walls of the enclosure at the corner regions  1806  have a greater thickness than the walls  1802  at the peripheral sides of the enclosure  1800 . By increasing the thickness of the walls at the corners, stresses or forces from impacts (e.g., from the device being dropped) may be less likely to break, crack, or otherwise damage the glass of the enclosure  1800 . The thickest portion of the corner regions  1806  may be any suitable thickness, such as about 3 mm, 2.5 mm, 2.0 mm, 1.5 mm, 1.0 mm, 0.5 mm, or any other suitable dimension. The walls of the enclosure  1800  (e.g., a central region of any of the peripheral sides or the first or second major sides) may have a different thickness, which may be about 2.0 mm, 1.5 mm, 1.0 mm, 0.5 mm, 0.25 mm, or any other suitable dimension. While the walls are shown having an increased thickness only at the corner regions  1806 , other portions of the enclosure  1800  may have increased thicknesses as well, and the particular shape of the walls at the corner regions  1806  may also be modified from what is shown in  FIG. 18 . 
       FIG. 19  shows a cross-sectional view of another example enclosure  1900 , viewed along line C-C in  FIG. 5B , in which the enclosure  1900  has regions of different thicknesses. For example, the enclosure  1900  defines a major side  1904  (which may correspond to a first or second major surface as described herein), and peripheral sides  1902  and  1903 . The peripheral sides  1903  may have an increased thickness relative to another portion of the enclosure  1900 , such as the regions  1910  of the peripheral sides  1902 . The region of increased thickness may extend along a complete length of the peripheral sides  1903  and along part of the peripheral sides  1902  (e.g., the regions  1905 ). In this way, the peripheral sides  1903  and the corners of the enclosure  1900  may be strengthened, relative to sides of a lesser thickness, while other regions of the enclosure  1900  (e.g., the regions  1910  of the peripheral sides  1902  and optionally the wall defining the major side  1904 ) may be thinner to provide other advantages, such as flexibility, transparency, optical clarity, or the like. In some cases, the peripheral sides  1903  and the regions  1905  of the peripheral sides  1902  may have substantially the same thickness. In other cases, the peripheral sides  1903  and the regions  1905  of the peripheral sides  1902  have different thicknesses from one another. 
     In some cases, thinner regions  1910  of the peripheral sides  1902  be deformable and/or deflectable in response to an application of a force-based input. For example, the user may be able to squeeze the enclosure  1900  and/or press on the regions  1910  of the peripheral sides in a manner that deforms and/or deflects one of the peripheral sides  1902 . This deformation and/or deflection may be sensed by a force sensing system within the enclosure  1900  (e.g., a capacitive-based force sensing system, or the like). If the input satisfies a threshold force or deflection, the device may register that an input has occurred and change or control the operation of the device accordingly. For example, a force-based input on one or both of the peripheral sides  1902  (which causes a deformation or deflection of the glass) may cause the device to silence a ringer or alarm, change a volume of the device, activate or deactivate a display, or the like. The force-sensing system that detects deformation and/or deflection of the peripheral sides  1900  may be used to detect inputs to affordances that are displayed on or otherwise viewable through a peripheral side, such as the speaker volume affordances  130  ( FIG. 1A ). 
       FIG. 19  shows a cross-sectional view of the enclosure  1900 . The full enclosure may be formed by attaching two glass members together. For example, the cross-section shown in  FIG. 19  may be half of the enclosure  1900 , and the other half may be substantially identical to the half shown in  FIG. 19 . The two halves may be attached to one another to form the complete enclosure by any suitable technique, including glass frit bonding, adhesives, laser welding, ultrasonic welding, glass fusion processes, or mechanical interlocking. In some cases, the two members that define the enclosure  1900  are not identical. For example one of the members may define more of (or all of) the peripheral side walls. Attachment techniques (and enclosure member configurations) that may be used to form the enclosure  1900  include those described herein with respect to  FIGS. 21A-21F . 
       FIG. 20A  shows a cross-sectional view of another example enclosure  2000 , viewed along line B-B in  FIG. 5B , in which the enclosure  2000  has regions of different thicknesses. The enclosure  2000  may include walls defining first and second major sides  2002 ,  2004 , and walls defining first and second peripheral sides  2006 ,  2008 . The corner or transition region  2010  between the major sides  2002 ,  2004  and the peripheral sides  2006 ,  2008  may have an increased thickness relative to the main (e.g., central or middle) regions of the major and peripheral sides. The increased thickness in these regions may increase the strength, stiffness, rigidity, or other physical property of the enclosure  2000  while still leaving large areas of the major sides and peripheral sides, which may be display and/or interface surfaces, more flexible, more optically clear, or the like. 
       FIG. 20A  shows an enclosure with a substantially rectangular cross-section. However, the same and/or similar principles may be used in enclosures of different shapes.  FIG. 20B , for example, shows a cross-sectional view of another example enclosure  2020 , viewed along line B-B in  FIG. 5B , in which the enclosure  2020  has regions of different thicknesses. The enclosure  2020  has a more rounded or contoured shape and, in particular, has rounded or contoured transitions or corners between its first and second major sides  2022 ,  2024  and adjacent peripheral sides  2026 ,  2028 . Further, the regions of greater thickness  2030  (located at the corners or transitions between the first and second major sides  2022 ,  2024  and adjacent peripheral sides  2026 ,  2028 ) may have smooth or contoured transitions between the areas of different thicknesses. 
     Other configurations of variable-thickness enclosures are also possible. Moreover, any of the variable thickness configurations described herein may be present in an enclosure of any construction. For example, the configurations shown in  FIGS. 18-20B  may be incorporated in any of the enclosure constructions described with respect to  FIGS. 6A-15 . 
     The foregoing figures depict various examples of enclosures that have at least two glass members joined together to form the enclosure and define substantially all of the exterior surfaces of the enclosure. As noted above, the various glass members may be joined to one another using various different joint geometries and attachment techniques. More particularly, the interfacing portions of the glass members may have various complementary mating geometries such as butt joints, miter joints, scarf joints, interlocking structures, complementary protrusions and recesses, and the like. Such joints may imbue the enclosure with desired properties, such as increased strength (e.g., resistance to becoming unjoined, increased overall enclosure strength), decreased joint visibility, increased interfacing surface area (e.g., for increased adhesive), and the like. Moreover, the joints may be configured so that the seam between two glass members is in a preferred location, such as at a corner or transition between a major side and a peripheral side, where the seam may be less likely to occlude or interfere with the visibility of displays that are visible through those sides. 
       FIGS. 21A-21F  show cross-sectional views of example enclosures, viewed along line B-B in  FIG. 5B , showing various example joint configurations between two glass members.  FIG. 21A , for example, shows an enclosure  2100  that includes a first glass member  2102 , which may include a wall defining a first major side of the enclosure  2100 , and a second glass member  2104 , which may include walls defining a second major side and peripheral sides of the enclosure  2100 . The first glass member  2102  may include or define a protrusion  2106  (which may be formed by molding, machining, or any other suitable technique) that is received in a corresponding recess  2108  in the second glass member  2104 . The protrusion  2106  and recess  2108  may be configured as a post and hole, a ridge and a channel, or any other suitable geometry. Where the protrusion  2106  and recess  2108  are configured as a post and a hole, they may be round, square, triangular, or any other suitable shape. As shown, the first glass member  2102  includes the protrusion  2106  and the second glass member  2104  includes the recess  2108 , though these positions may be reversed. 
       FIG. 21A  shows one particular location of the protrusion  2106  and the recess  2108  (e.g., with sides of the first glass member  2102  exposed and defining a portion of the peripheral sides of the enclosure  2100 ), though this is merely one example configuration of the joint structure in a glass enclosure. In other cases, complementary protrusions and recesses may be used in other locations and/or positions. For example, the first and second glass members  2102 ,  2104  may be configured so that the seam is positioned on or around the first major side, rather than on the peripheral sides as shown (e.g., so that sides of the second glass member  2104  are exposed and define a portion of the first major side). Moreover, in cases where the enclosure does not have the exact shape shown in  FIG. 21A , such as enclosures with rounded peripheral sides that do not include any planar portions, a protrusion and receptacle joint may be configured differently than what is shown in  FIG. 21A . It will be understood that this type of joint may be used to join glass members of various different shapes and configurations and in various different locations without departing from the scope of the instant description. For example, this joint may be used to join any of the glass members described with respect to  FIGS. 6A-20B . 
       FIG. 21B  shows an enclosure  2110  with another example joint configuration between a first glass member  2112  and a second glass member  2114 , in which the first glass member  2112  defines a recess  2116 , similar to a rabbet joint, that receives a portion of the second glass member  2114  therein. The second glass member  2114  may maintain a constant thickness in the area of the joint, or it may include a tapered or reduced-thickness area that is received in the recess  2116 . As noted above, though  FIG. 21B  shows a joint at one particular location (e.g., at a corner or transition between a major side and a peripheral side), a similar joint may be used in other locations and/or between other glass members. For example, the recess may be formed in the second glass member  2114  rather than the first glass member  2102 , and the joint may be formed so that the seam is on the major side instead of the peripheral side as shown. 
       FIG. 21C  shows an enclosure  2120  with another example joint configuration between a first glass member  2122  and a second glass member  2124 , in which the first and second glass members are mitered or angled to form a diagonal or angled interface between the first glass member  2122  and the second glass member  2124 . The mitered joint may increase the surface area of the interfacial surfaces as compared to other joints, and as such may be stronger than other joints. Moreover, the mitered joint may allow the seam of the joint to be positioned at or along the corner or transition between a major side and a peripheral side, which may reduce the visibility of the seam itself as well as optical interference that may be noticed when viewing an underlying display through the interfacial surfaces of a joint. 
       FIG. 21D  shows an enclosure  2130  with another example joint configuration between a first glass member  2132  and a second glass member  2134 , in which both the first and second glass members  2132 ,  2134  include walls  2136  that define a portion of the peripheral sides of the enclosure. In this example, the walls  2136  of both the first and second glass members  2132 ,  2134  include or define interlocking structures that mechanically engage one another to retain the first and second glass members  2132 ,  2134  to one another. The interlocking structures may include undercuts, curved or rounded undercuts, threads, lips, ledges, dovetails, interference fits, or other mechanical configurations that, when engaged with one another, retain the glass members together. 
       FIG. 21E  shows an enclosure  2140  with another example joint configuration between a first glass member  2142  and a second glass member  2144 , in which both the first and second glass members  2142 ,  2144  include walls  2146  that define a portion of the peripheral sides of the enclosure. In this example the walls  2146  of both the first and second glass members  2142 ,  2144  include or define curved surfaces, similar to a scarf or splice joint. The curved surfaces may produce a mechanically strong joint while also reducing optical artifacts of the joint or even enhancing the optical properties of the glass enclosure relative to an underlying display. For example, the curved surfaces may produce a desired lensing effect (or have little or no lensing) so that, despite viewing a display through the interfacial surfaces of the joint, an underlying display may appear undistorted from multiple viewing angles. 
       FIGS. 21A-21E  show examples of enclosures that have substantially flat or planar major sides and peripheral sides. As noted above, any of these joints may be used with enclosures of different shapes or geometries, including enclosures that have curved or rounded major and/or peripheral sides or the like.  FIG. 21F  shows an enclosure  2150  that has peripheral sides that have a continuous curve extending from a first major side to a second major side. The enclosure  2150  uses a joint configuration similar to that shown in  FIG. 21E . For example, portions of the first and second glass members  2152 ,  2154  that define the peripheral walls have tapered regions  2156  (e.g., tapered edges) that overlap one another. The tapers of these members may be configured so that the overall thickness of the enclosure  2150  remains substantially constant, even across the joint region where the members overlap. In some cases, the tapers are configured so that the overall thickness of the enclosure  2150  remains substantially constant across the overlapping region and the regions of the enclosure adjacent the overlapping region (e.g., allowing for the enclosure to have different thicknesses elsewhere). By maintaining a constant thickness, the walls that define the peripheral sides may provide improved optical clarity, as compared to a peripheral wall of variable thickness, to provide clear viewing of underlying displays or other optical components. 
     The tapered regions  2156  (e.g., tapered edges) may also provide an interlocking structure that provides a mechanical engagement that retains the first and second glass members  2152 ,  2154  to one another. In particular, the shape of the first glass member  2152  may be configured to receive and retain (and optionally compress) the tapered regions  2156  of the side walls of the second glass member. During assembly, the first glass member  2152  may be expanded or bent to allow the side walls of the second glass member  2154  to be positioned inside the side walls of the first glass member  2152 . The pressure of the side walls of the first glass member  2152  on the side walls of the second glass member  2154  in the area of the tapered regions  2156 , as well as the shapes of the tapered regions  2156 , may mechanically retain the second glass member  2154  to the first glass member  2152 . 
       FIGS. 22A-22B  show additional examples of joint configurations between first and second glass members. For example,  FIG. 22A  shows a perspective view of an enclosure  2200  that includes a first glass member  2202  joined to a second glass member  2204 . The peripheral sides of the first and second glass members  2202 ,  2204  each have complementary scalloped (or other interdigitated) structures that define a non-linear seam  2206  around the peripheral sides of the enclosure  2200 . The scalloped structures and the resulting non-linear seam  2206  may reduce the visibility of the seam between the two glass members  2202 ,  2204  by producing a more irregular shape that is less visually noticeable. Additionally, the scalloped structures may provide an increased joining surface area as compared to a straight or linear joint, which may consequently increase the strength of the joint between the first and second glass members  2202 ,  2204 . 
       FIG. 22B  shows a perspective view of another example enclosure  2210  that includes a first glass member  2212  joined to a second glass member  2214 . The peripheral sides of the first and second glass members  2212 ,  2214  each have complementary toothed structures that define a non-linear seam  2216  around the peripheral sides of the enclosure  2210 . The toothed structures may function substantially similarly to the scalloped structures in  FIG. 22A , and may provide similar properties (e.g., increased strength and reduced visibility as compared to a straight joint). 
     In each of the foregoing examples, the glass members may be secured to one another in any suitable way. For example, glass members may be secured using adhesive between the joint surfaces of the glass members (e.g., epoxy, glass cement, etc.). Where adhesives are used, they may substantially completely cover the interfacing surfaces, or they may cover only a portion the interfacing surfaces. Glass members may also be secured using glass frit bonding, laser welding, ultrasonic welding, glass fusion processes, or mechanical interlocking alone. Where fusion or melting is used to secure the glass members, the glass may be locally fused at or near the exterior surfaces of a joint. For example, with respect to  FIG. 21A , a laser may fuse the glass near the exterior and/or interior surfaces of the glass members in proximity of the joint without reaching all of the interfacial surfaces of the joint (e.g., the protrusion and the recess may not be melted or directly fused during or as a result of the fusion process). 
     As noted, the securing technique and joint geometry used in a glass enclosure as described herein may be selected to reduce the visibility or detectability of seams between joined glass members. For example, where adhesives, glass frit, or other interstitial materials are included between interfacing surfaces, those materials may have the same or similar refractive index (and/or other optical properties) as the glass members themselves. This may reduce refraction or other optical phenomena that may occur due to the joints. Moreover, the joints, and the glass members more broadly, may be subjected to post-joining operations to further reduce the visibility of the joints, including grinding, lapping, or other material removal operations (e.g., to remove excess glass and/or produce a desired exterior surface profile), polishing, and the like. 
     Visible seams between glass enclosure members may be undesirable in glass enclosures. For example, as noted above, seams where glass enclosure members are joined and/or overlap one another may optically distort underlying displays, detract from the appearance and/or feel of the device, or otherwise be problematic. In some cases, portions of enclosures may be textured, frosted, bead- or sand-blasted, or otherwise modified to hide or otherwise reduce the visibility of a seam. In some cases, texturing may have both tactile and optical artifacts. For example, a textured region may appear different than a non-textured region, and may also have a different tactile feel than a non-textured region. In some cases, a textured region has a different optical or visual appearance but has substantially the same tactile feel. 
       FIG. 23A  shows a perspective view of an enclosure  2300 , which may be formed of two or more glass members joined together and may define a seam where the glass members meet or overlap.  FIG. 23B  shows a cross-sectional view of the enclosure  2300 , viewed along line E-E in  FIG. 23A , showing a first glass member  2306  (which may define a first major side  2302  and at least two of the peripheral sides  2303 ) joined to a second glass member  2308  (which may define a second major side  2304 ,  FIG. 23B ) and defining a seam  2312  therebetween. As shown, the seam  2312  is positioned at a corner or transition between the first major side  2302  and the peripheral sides  2303 , though this is merely exemplary. 
     The enclosure  2300  includes a textured region  2310 . The textured region  2310  may extend along the exterior surface of the enclosure and cover or otherwise obfuscate the seam  2312 . As shown, the textured region  2310  covers all of the peripheral sides  2303  and part of the first and second major sides  2302 ,  2304 , though the textured region  2310  may extend over a smaller surface of the enclosure  2300 , such as substantially only the area of the seam  2312  and a small surrounding area (e.g., covering the width of the seam and less than 2.0 mm, less than 1.0 mm, or less than 0.5 mm of the material on either side of the seam).  FIG. 23C  shows another example of the enclosure  2300  in which a textured region  2320  extends over only a portion of the peripheral sides  2303  and a portion of the second glass member  2308 . The particular location and extent of a textured region may be selected based on locations of underlying displays. For example, the configuration shown in  FIG. 23B  may be used for devices that include front- and back-facing displays (e.g., displays visible through the first and second major sides  2302 ,  2304 ), and no image-displaying displays that are visible through the peripheral sides  2303  (though non-image forming light may still be visible through the textured peripheral sides  2303 ). The configuration shown in  FIG. 23C , on the other hand, may be used for devices that include displays that are viewable through the peripheral sides  2303 . 
     The textured regions may be formed in any suitable manner. For example, the enclosure  2300  may be subjected to a finishing operation such as grinding, lapping, abrasive-blasting (e.g., sand blasting, bead blasting, or the like), etching (e.g., laser etching, plasma etching, chemical etching, or the like), or any other suitable process. In some cases, the textured region may include or be formed of material that is added to and/or coated on the glass of the enclosure, such as ink, dye, powder, or the like. The textured regions may be tactilely different than non-textured regions, or they may be tactilely indistinguishable from non-textured regions. Also, in  FIGS. 23A-23C , the textured regions are shown on the outside or exterior surface of the enclosure  2300 , though texturing may also or instead be on the inside of the enclosure (e.g., along an interior surface of the enclosure). 
     Glass members that form a glass enclosure as described herein may be formed in various ways.  FIGS. 24A-25B  show two non-limiting examples of methods of forming glass members, such as any of the glass members described herein. While  FIGS. 24A-25B  show molds having particular shapes, these are merely examples, and molds may have any suitable shape to form any of the foregoing glass enclosure members, or others that are not explicitly illustrated herein. 
       FIGS. 24A-24B  illustrates a molding or slumping process by which a glass member is shaped by a mold  2402 . In particular, a glass sheet  2400  ( FIG. 24A ) may be heated (prior to and/or while in contact with the mold  2402 ) and allowed to conform or slump to the shape of the mold  2402 . A second mold may optionally be used to force the glass sheet  2400  against the mold  2402  to conform the glass sheet to the mold. Additionally or alternatively, air pressure differentials may be used to force the glass sheet against the mold (e.g., the mold may include vacuum lines that draw the glass against the mold). The resulting shaped glass member  2404  ( FIG. 24B ) may be removed from the mold  2402  ( FIG. 24B ) and optionally subjected to further processing, such as cleaning, texturing, polishing, removing excess material, flashing, or walls, or the like. Multiple molds may be used to make complementary glass members that may then be joined together to form a complete enclosure. 
       FIGS. 25A-25B  illustrate another example process, resembling a blow-molding process, for forming glass members.  FIGS. 25A-25B  show a representative cross-section of the process that corresponds to a view of an enclosure along line B-B in  FIG. 5B . In particular, a glass preform  2500  (or parison) may be heated to or above a softening temperature and placed proximate a mold  2502 . A pressure differential between the environment in an interior cavity of the glass preform  2500  and the environment around the glass perform  2500  (e.g., caused by forcing a fluid such as air into the preform  2500  through an inlet  2503  and/or applying a vacuum around the preform  2500 ) may cause the preform to expand and conform to a shape of the mold  2502 . When fully formed, the glass preform  2500  may be formed into an intermediate glass member  2504 , which may then be subjected to further processing to form a glass enclosure member as described herein. For example, the inlet  2503  may be removed from the intermediate glass member  2504  to form an enclosure member that defines substantially all of six sides of a glass enclosure. As another example, one or more walls may be entirely or partially removed from the intermediate glass member  2504 , such as by cutting along cut lines  2506  or  2508 , to form a glass member that may be joined with another glass member to form a complete glass enclosure. 
       FIGS. 25C-25D  illustrate another example process, resembling a blow-molding process, for forming glass members.  FIGS. 25C-25D  show a representative cross-section of the process that corresponds to a view of an enclosure along line B-B in  FIG. 5B . In particular, a glass preform  2510  (or parison) may formed, and device components  2511  may be inserted into the glass preform  2510  through an opening in the glass preform  2510 . The device components  2511  may include components such as displays, circuit boards, memory, processors, sensors, charging components, microphones, wireless radios, or any other suitable components to be contained within an enclosure for an electronic device such as a smartphone, tablet computer, smart watch, or the like. 
     After the device components  2511  are inserted into the glass preform  2510  (and optionally maintained in a particular position relative to the glass preform  2510  by a support mechanism  2515 ), the glass preform  2510  may be heated to or above a softening temperature and placed proximate a mold  2512 . A pressure differential between the environment in an interior cavity of the glass preform  2510  and the environment around the glass perform  2510  (e.g., caused by forcing a fluid such as air into the preform  2510  through an inlet and/or applying a vacuum around the preform  2510 ) may cause the preform to expand and conform to a shape of the mold  2512 . As part of the molding and/or shaping process, portions  2513  of the glass preform  2510  may be drawn together to close the opening through which the device components  2511  were inserted into the glass preform  2510  and form an enclosure  2514  around the device components  2511 . After the portions  2513  are drawn together, any remaining glass of the portions  2513  may be ground, machined or otherwise removed to form a substantially smooth and/or featureless surface. 
     In some cases, the portions  2513  may not be drawn completely together, and instead an opening may remain in the enclosure  2514 . The opening may be closed or capped (e.g., with a piece of glass, plastic, metal, etc.), or it may be used as an opening through which a component may extend into the internal volume of the enclosure  2514 . For example, a biometric sensor may be positioned at least partially in the remaining opening to both (1) close the opening, and (2) provide a mounting location for the biometric sensor. In other cases, a button, microphone, speaker, crown, or other input or output device may be positioned at least partially in an opening that remains in an enclosure after a molding and/or forming process. 
     The size and shape of the glass preforms and resulting enclosures in  FIGS. 25A-25D , as well as the relative location of the inlets and/or openings on the preforms and enclosures, are merely examples, and other configurations are also contemplated. For example, the inlet and/or opening may be provided along a peripheral side of a preform or enclosure. As one specific example, where an enclosure for a watch is being formed, an opening may be provided along a peripheral side of a glass preform, and device components may optionally be inserted through the opening prior to a molding or forming operation that shapes the preform and/or closes (fully or partially) the opening. If the opening is not fully closed, the opening may be used as an opening for a component of a crown and/or button to enter the interior volume of the enclosure. 
       FIGS. 24A-25D  show several example glass forming processes that may be used to produce glass enclosure members, though other processes are also possible. For example, enclosure members may be formed by joining multiple glass sheets or other sub-members, using adhesives, frit bonding, laser welding, or other attachment techniques, or glass may be extruded to define tube-like enclosure members that may be capped to form a glass enclosure having each side at least partially formed of glass. 
     One benefit of an enclosure that has multiple sides formed from transparent glass is that displays may be viewable through multiple transparent walls of the enclosure. As described above, this may include displays that are visible through as many as all of the sides of an enclosure (such as through six sides in the case of a substantially rectangular prism, through the bases and cylindrical wall of a cylindrical enclosure, or the like). Conventional flat or planar displays, however, may not be particularly well suited to a device with displays viewable through multiple sides, especially in cases where portions of a display may be rounded or curved (e.g., in the context of an enclosure with rounded peripheral sides), or extend continuously across a bend or corner (e.g., in the area of a corner or transition between a major side and a peripheral side or around a cylindrical wall).  FIGS. 26A-32B  illustrate various examples of display components that may be used in conjunction with glass enclosures to display images through multiple (e.g. two, three, four, five, or six) sides of the device. These displays may include various combinations of flat and/or planar display members, as well as curved display members. Flat or planar display members may be formed from or include either or both of rigid display components and flexible display components, which may be assembled and/or joined together in various ways to provide display regions that may appear seamless or otherwise continuous even between disparate sides of the device. For example, a flat display member may be formed from or include flexible display components arranged in a flat configuration, or it may be formed from or include a substantially rigid display component. Similarly, a curved display member may be formed from or include flexible display components that are flexed or otherwise forced into a desired curved shape (and optionally held in that shape by a support structure, a portion of an enclosure, or the like), or it may be formed from or include rigid display components that happen to have a curvature. 
       FIGS. 26A-26C  show an example display component  2600  that may define six display regions  2602 - 1 - 2602 - 6 , one region for each side of a six-sided transparent enclosure (e.g., a rectangular prism). In embodiments where an enclosure includes six sides but not all sides include a display, that corresponding portion of the display component  2600  may be omitted or inoperative. The display component  2600  may be or may include a liquid crystal (LCD) panel, an organic light emitting diode (OLED) panel, active-matrix organic light-emitting diode (AMOLED) panel, or any other suitable component(s) of a display. The display component  2600  may carry or may include light and/or color producing components that are form images. 
     The display component  2600  may include a material or combination of materials that can be folded or flexed to produce a display that is viewable through multiple sides of an enclosure. For example,  FIG. 26A  illustrates fold lines  2604  along which the display component  2600  may be folded, flexed, bent, or otherwise formed to define a final shape of the display component  2600  ( FIG. 26C ) in which each of the six display regions  2602 - 1  through  2602 - 6  form an outward-facing side of the display component  2600 . As shown, each of the display regions  2602  may be substantially planar, though other shapes and configurations are also possible, including curved and/or rounded configurations. 
     The display component  2600  may be formed of or include any suitable display technology. For example, it may include a flexible substrate (or stack of substrates or layers) that can be folded from a substantially flat sheet into the configuration shown. In other cases, it may include rigid portions that may be joined by flexible interconnecting members. For example, the segments of the display corresponding to the regions  2602 - 1  through  2602 - 6  may be substantially rigid (e.g., not capable of bending more than about 30 degrees without breaking or permanent deformation), while the portions of the display component  2600  corresponding to the fold lines  2604  may be flexible (e.g., segments of the material having a width of about 0.5 mm, 1.0 mm, 1.5 mm, 2.0 mm, or any other suitable dimension, along which the display component  2600  may be folded up to about 90 degrees or more without breaking). The flexible portions may be capable of forming images or they may be non-image-forming interconnects that electrically and physically couple rigid segments together. 
     While the folded corners or regions are shown as having a particular example radius, this is merely an example, and the radius of curvature (or other geometric characterization of the curve) of the material that is folded, flexed, or bent may be any suitable value that results in a suitable shape without damaging the material. The same or similar principles apply to other flexible display components described herein. 
     In some cases the display component  2600  may have optional flaps  2605  or extensions ( FIGS. 26A-26C ) that are positioned at or near the corners between adjacent display regions when the display component  2600  is folded, bent, or otherwise formed into a final shape. When folded, the flaps  2605  may align with an adjacent flap or display region to help reduce or eliminate any gap between portions of the display component  2600 . More particularly, the flaps  2605  may have image-forming capabilities, and by aligning the flaps  2605  with one another and/or with other portions of the display component  2600  when the display is formed into its final shape, as shown in  FIGS. 26B-26C , discontinuities or blank spaces in the display component  2600  may be reduced or eliminated. This configuration may produce the appearance that the display component  2600  is a single, unified display surface that is extends over multiple sides of a device, rather than individual displays simply placed near each other. While  FIGS. 26A-26C  show flaps extending from various portions of the display component  2600 , similar flaps may be positioned elsewhere on the display component  2600  to help reduce or eliminate visible gaps or seams between display regions. 
     Whether or not flaps are used, portions of the display component  2600  may be secured to one another after being folded or otherwise formed into a target shape. For example, abutting or overlapping or otherwise adjacent display regions may be adhered to one another (e.g., with epoxy, pressure sensitive adhesive (PSA), heat sensitive adhesive (HSA), or any other suitable bonding agent), mechanically secured (e.g., with interlocking structures), or otherwise structurally secured to maintain the display component  2600  in a desired shape. 
       FIGS. 26A-26C  show an example display component  2600  that may be used in a six-sided transparent enclosure. The structure and techniques described with respect to the display component  2600  may be applicable by analogy to displays for use in enclosures having other shapes. For example,  FIGS. 26D-26F  show an example display component  2620  that may be used in a cylindrical transparent enclosure, such as the enclosure  422  in  FIG. 4C  or the enclosure  442  in  FIG. 4D  (or any other suitably shaped enclosure). The display component  2620  may define a first display region  2622  corresponding to a cylindrical wall of an enclosure, a second display region  2624  corresponding to a first base of the enclosure, and a third display region  2626  corresponding to a second base of the enclosure. The display component  2620  may be or may include a liquid crystal (LCD) panel, an organic light emitting diode (OLED) panel, active-matrix organic light-emitting diode (AMOLED) panel, or any other suitable component(s) of a display. The display component  2620  may carry or may include light and/or color producing components that are form images. 
     The display component  2600  may include a material or combination of materials that can be folded or flexed to produce a display that is viewable through multiple sides of an enclosure. For example,  FIG. 26D  illustrates fold lines  2625  along which the display component  2620  may be folded, flexed, bent, or otherwise formed to define a final shape of the display component  2620  ( FIG. 26F ) in which each of the display regions  2622 ,  2624 ,  2626  form an outward-facing side of the display component  2620 . As shown, the second and third display regions  2624 ,  2626  may be substantially planar, while the first display region  2622  is curved into a cylindrical shape.  FIG. 26E  shows the display component  2620  at an intermediate state during the forming of the display component  2620  into its final shape. 
     The display component  2620  may be formed of or include any suitable display technology, as described above with respect to the display component  2600  or other display components described herein. Further, the edges of the display component  2620  may be attached or secured to one another using any suitable structure(s) and/or technique(s) described herein, including with overlapping flaps or edge portions of the display component, butt joints, adhesives, interlocking structures, or the like. 
       FIGS. 27A-27B  show another example display component  2700  that may define six display regions (e.g., one region for each side of a six-sided transparent enclosure). The display component  2700  ( FIG. 27B ) may include a first display member  2702  and a second display member  2704 . Both the first and second display members  2702 ,  2704  (and indeed any display member described herein) may be or may include a liquid crystal (LCD) panel, an organic light emitting diode (OLED) panel, active-matrix organic light-emitting diode (AMOLED) panel, or any other suitable component(s) of a display (including but not limited to filters, polarizers, films, coatings, and the like). The first display member  2702  may be folded along fold lines  2706  to define five display regions (e.g., corresponding to a first major side and four peripheral sides of an enclosure). Accordingly, the first display member  2702  may include flexible materials, such as electrical interconnects, at least in the region of the fold lines  2706  (with other portions of the display, such as the display regions, being either flexible or rigid, as described above). 
     The second display member  2704  may be a substantially planar member that defines a display region corresponding to a second major side of an enclosure. After the first display member  2702  is folded as shown in  FIG. 27B , the first and second display members  2702 ,  2704  may be attached to one another (e.g., using adhesives, interlocking structures, or other techniques), or otherwise positioned in an enclosure proximate one another to give the appearance of a continuous display that extends over multiple sides of the device. Also, the first and/or the second display members  2702 ,  2704  may include flaps or other overlapping structures to eliminate or reduce the appearance of gaps or seams between display regions, as described above. 
       FIGS. 28A-28C  show another example display component  2800  that may define six display regions (e.g., one region for each side of a six-sided transparent enclosure). The display component  2800  ( FIG. 28B ) may include a first display member  2802  and a second display member  2804 . Both the first and second display members  2802 ,  2804  may be or may include a liquid crystal (LCD) panel, an organic light emitting diode (OLED) panel, active-matrix organic light-emitting diode (AMOLED) panel, or any other suitable component(s) of a display. The first and second display members  2802 ,  2804  each define a major side and a portion of each of the peripheral sides. For example, the first and second display members  2802 ,  2804  may each define approximately half of a peripheral side. The first and second display members  2802 ,  2804  may be joined together or otherwise positioned relative to one another to define up to six display regions, each corresponding to and visible through a side of a glass enclosure as described herein. 
     The first and second display members  2802 ,  2804  may be formed in a similar manner, and may include similar flexible and/or rigid components, as the first display member  2702  described above. Also, the first and/or the second display members  2802 ,  2804  may include flaps or other overlapping structures to eliminate or reduce the appearance of gaps or seams between display regions, as described above. The first and/or the second display members  2802 ,  2804  may be joined to one another using adhesives, interlocking structures, support members or structures, or any other suitable joining or positioning technique. 
       FIG. 28C  shows a perspective view of the display component  2800  after the first and second display members  2802 ,  2804  have been joined, showing how the first and second display members  2802 ,  2804  overlap one another along the peripheral side of the display component  2800 . For example, the terminal end  2806  of the first display member  2802  may be on the exterior surface of the display component  2800 . The terminal end  2808  of the second display member  2804  may be under a portion of the first display member  2802 , such that the terminal end  2808  is on the interior surface of the display component  2800 . This overlapping configuration may help reduce the appearance of a seam between the display members  2802 , and may help reduce discontinuities between images or graphical outputs displayed along the peripheral sides of the display members  2802 ,  2804 . 
       FIGS. 29A-29C  show another example display component  2900  that may define six display regions (e.g., one region for each side of a six-sided transparent enclosure). The display component  2900  may include a first display member  2902  and a second display member  2904 . Both the first and second display members  2902 ,  2904  may be or may include a liquid crystal (LCD) panel, an organic light emitting diode (OLED) panel, active-matrix organic light-emitting diode (AMOLED) panel, or any other suitable component(s) of a display. The first display member  2902  defines a major side of the display component  2900  and a portion of four peripheral sides of the display component  2900 . The second display member  2904  defines another major side of the display component  2900 . 
     The first display member  2902  also includes curved corner portions  2910 , and the second display member  2904  includes tabs  2906 . When the first and second display members  2902 ,  2904  are folded or formed to their final shapes (e.g., by folding along the dotted lines in  FIG. 29A ), the tabs  2906  and the corner portions  2910  may define curved corner portions between adjacent peripheral sides of the display component  2900 , as shown in  FIG. 29C . This configuration may be used in conjunction with glass enclosures that have curved or rounded corners. 
     In some cases, the curved corner portions may also be able to substantially seamlessly display graphical outputs, such as graphical outputs that extend across multiple sides of the device, and the curved corner portions may have substantially the same display properties than the main and peripheral sides of the display. In other cases, the tabs  2906  may have different display properties than other portions of the first and/or second display members. For example, the tabs  2906  may have different pixel configurations (e.g., resolution, pixel size, pixel type, etc.) than the portions of the first and/or second display members that are visible through the major and peripheral sides of an enclosure. In some cases, the tabs  2906  may have the same or similar pixel configurations, but may be programmatically configured to produce lower-resolution images than other portions of the display members, and may even be configured to emit light without any discernable images. 
     The first and second display members  2902 ,  2904  may be formed in a similar manner, and may include similar flexible and/or rigid components, as the first display member  2702  described above. Also, the first and/or the second display members  2902 ,  2904  may include flaps or other overlapping structures to eliminate or reduce the appearance of gaps or seams between display regions (e.g., as described herein with reference to  FIGS. 35A-37 ). The first and/or the second display members  2902 ,  2904  may be joined to one another using adhesives, interlocking structures, support members or structures, or any other suitable joining or positioning technique. 
       FIG. 30  shows another example display component  3000  that may define six display regions (e.g., one region for each side of a six-sided transparent enclosure). The display component  3000  may include a first display member  3002  and a second display member  3004 . Both the first and second display members  3002 ,  3004  may be or may include a liquid crystal (LCD) panel, an organic light emitting diode (OLED) panel, active-matrix organic light-emitting diode (AMOLED) panel, or any other suitable component(s) of a display. The first display member  3002  defines a major side of the display component  3000  and a portion of four peripheral sides of the display component  3000 . The second display member  3004  defines another major side of the display component  3000 . 
     Instead of having elongated straight or linear seams between the first and second display members  3002 ,  3004 , these members may each include a complementary scalloped profile (or other interdigitated shape or structure) that, when the display members  3002 ,  3004  are joined or otherwise positioned to form the complete display component  3000 , define a non-linear, undulating, or curved seam between the two display members. This may reduce the visibility of the seam between the display members, as an irregular seam may be less visually noticeable, or it may be more easily hidden or obfuscated by images displayed on the peripheral sides of the display component  3000 . 
     The first and second display members  3002 ,  3004  may be formed in a similar manner, and may include similar flexible and/or rigid components, as the first display member  2702  described above. Also, the first and/or the second display members  3002 ,  3004  may include flaps or other overlapping structures to eliminate or reduce the appearance of gaps or seams between display regions, as described above. The first and/or the second display members  3002 ,  3004  may be joined to one another using adhesives, interlocking structures, support members or structures, or any other suitable joining or positioning technique. 
       FIGS. 31A-31B  show another example display component  3100  that may define six display regions (e.g., one region for each side of a six-sided transparent enclosure). The display component  3100  may use a combination of substantially planar display members and curved display members to form a display component  3100  that includes substantially flat main sides and curved peripheral sides, which may conform to the interior contours of a glass enclosure that includes curved peripheral sides (both along interior and exterior surfaces of the peripheral sides). For example, first and second display members  3102 ,  3104  may be substantially planar, while a third display member  3106  may be formed into a curved profile that defines a curved profile (e.g., corresponding to a curved peripheral side) and that defines curved profiles around the corners of the first and second display members  3102 ,  3104  (e.g., the curved corners between the peripheral sides). The first, second, and third display members  3102 ,  3104 ,  3106  may be or may include a liquid crystal (LCD) panel, an organic light emitting diode (OLED) panel, active-matrix organic light-emitting diode (AMOLED) panel, or any other suitable component(s) of a display. The first, second, and third display members  3102 ,  3104 ,  3106  may be any suitable combination of flexible and/or rigid displays. For example, the first and second display members  3102 ,  3104  may be more rigid than the third display member  3106 . 
     The third display member  3106  may have cutouts or segmented portions at corner regions  3108  ( FIG. 31B ) to allow the corner regions  3108  to conform to a curved profile along two directions. For example, the corner regions  3108  may follow a curved path along a direction that is substantially parallel to a plane defined by the first or second major side (arrow  3110 ), as well as a curve that is substantially perpendicular to the plane defined by the first or second major side (arrow  3112 ). Accordingly, the corner regions  3108  may resemble a portion of a sphere, rather than a portion of a cylinder. The corner regions  3108  may be configured to display images or colors, or they may be inactive regions that do not emit light or display images. 
     As noted above, the first, second, and/or third display members  3102 ,  3104 ,  3106  may include flaps or other overlapping structures to eliminate or reduce the appearance of gaps or seams between display regions, as described above. The first, second, and/or third display members  3102 ,  3104 ,  3106  may be joined to one another using adhesives, interlocking structures, support members or structures, or any other suitable joining or positioning technique. 
       FIGS. 32A-32B  show another example display component  3200  that may use a combination of substantially planar displays and curved displays to define six display regions (e.g., one region for each side of a six-sided transparent enclosure) with curved peripheral sides. Similar to the display component  3100 , the display component  3200  may be configured to conform to the interior contours of a glass enclosure that includes curved peripheral sides (both along interior and exterior surfaces of the peripheral sides). 
     With respect to  FIG. 32A , first and second display members  3202 ,  3204  may be or may include substantially planar display members, while third display members  3206 - 1  through  3206 - 4  may be formed into a rounded or curved profile. The first, second, and third display members  3202 ,  3204 ,  3206  may be or may include a liquid crystal (LCD) panel, an organic light emitting diode (OLED) panel, active-matrix organic light-emitting diode (AMOLED) panel, or any other suitable component(s) of a display. As noted above, the different display members may have different rigidities, such as the first and second display members  3202 ,  3204  being more rigid than the third display members  3206 - 1  through  3206 - 4 . 
     When assembled, the display component  3200  may define open corner regions  3208 . Other components, such as other display members (which may have a same or different pixel configuration as other display members of the display component  3200 ), light sources, or the like, may be positioned in or viewable through the open corner regions  3208 . In other cases, they may be inactive regions that do not display images or light, and covers, inks, dyes, or other materials may be used to cover or occlude the openings. 
     As noted above, the first, second, and/or third display members  3202 ,  3204 ,  3206  may include flaps or other overlapping structures to eliminate or reduce the appearance of gaps or seams between display regions, as described above. The first, second, and/or third display members  3202 ,  3204 ,  3206  may be joined to one another using adhesives, interlocking structures, support members or structures, or any other suitable joining or positioning technique. 
       FIGS. 26A-32B  describe various example configurations for multi-sided displays. In some cases, where display members are joined or positioned adjacent one another, seams or other artifacts of the joint may be visible. Similarly, glass enclosures that are formed of multiple glass members may have seams where the glass members are joined. In some cases, devices may be configured so that seams of a display component are aligned with seams of the enclosure that contains the display component. For example, the display component  2800  ( FIG. 28B ) may be used with the enclosure  700  ( FIG. 7B ), so that the seams that extend along the peripheral sides of the display component  2800  and the enclosure  700  are substantially aligned. This may help hide or minimize the visibility of the seams in the display component  2800 , because the seam in the enclosure  700  may cover the seam. 
     Also, the multi-sided displays described with respect to  FIGS. 26A-32B  may be configured to conform to and/or contact substantially all of the interior surfaces of the enclosure in which it is positioned. Thus, air gaps between the display surfaces and the interior surfaces of an enclosure may be reduced or eliminated, which may improve the visual appearance of the displays and minimize unused space, among other possible advantages. Finally, it will be understood that in any of the foregoing display components, fewer than six sides may be configured to display images or produce light. For example, in cases where only five or four sides of an electronic device are associated with a display, one or two of the sides of the display components described herein may be omitted or replaced with a component that is not configured to display images or light. 
     As described above, display components may comprise multiple display members that are attached to one another to form a single, multi-sided display. Where the display components overlap (and are optionally secured to one another via adhesive or another suitable technique), seams may be formed. In some cases, display components may be attached to one another in a manner that may reduce the visibility of any seams or overlap.  FIGS. 33-36B  illustrate example configurations of a joint or seam between two display members that may be used with any of the foregoing display components.  FIG. 33  shows an example display component  3300 , which resembles the display component  2800  ( FIG. 28B ), and includes a first display member  3302  attached to a second display member  3304 . 
       FIGS. 34A-34B  show an intersection between the first and second display members  3302 ,  3304 , according to an example joining technique. In particular,  FIG. 34A  shows a detail view of a peripheral wall of the display component  3300  corresponding to the area  3306  in  FIG. 33 , and  FIG. 34B  shows a partial cross-sectional view of the display component  3300 , viewed along line F-F in  FIG. 33 . In this example, the first and second display members  3302 ,  3304  each define a complementary toothed profile (or other interdigitated profile) along a joining portion or end of the display members. The toothed profiles engage one another to define an irregular seam  3402 , which may be less noticeable than (or easier to hide with displayed images or other display techniques) than a single elongated linear seam, as described above. As shown in  FIG. 34B , the joining portions of the first and second display members  3302 ,  3304  may abut one another in a non-overlapping configuration, such that the first display component  3300  maintains a substantially constant thickness across the seam  3402 . 
       FIGS. 35A-35C  show an intersection between the first and second display members  3302 ,  3304 , according to another example joining technique.  FIG. 35A  shows a detail view of a peripheral wall of the display component  3300  corresponding to the area  3306  in  FIG. 33 , and  FIG. 35B  shows a partial cross-sectional view of the display component  3300 , viewed along line F-F in  FIG. 33 . In this example, one or both of the first and second display members  3302 ,  3304  define a fringed profile along a joining portion or end. The fringed profile includes teeth or tapered shapes that, due to their non-linear or irregular configuration, may help hide or reduce the visibility of the seam  3502  between the first and second display members  3302 ,  3304 . As shown in  FIG. 35B , the first and second display members  3302 ,  3304  may be tapered in an overlapping region that corresponds to the seam  3502 . The tapered shapes may avoid or reduce abrupt transitions or discontinuities where one display member overlaps the other. Because abrupt transitions may increase the visibility of the seam by having an inactive edge region of a display member visible to a user, the tapered overlapping region as shown in  FIG. 35B  may reduce the visibility of the seam  3502 . (Where only one of the display members defines a fringed profile, the display member with the fringed profile may overlie the other display member so that the fringed profile defines the exterior or visible surface of the display.) 
       FIG. 35C  shows a partial exploded or unassembled view of the display component  3300 , further illustrating how the display members  3302 ,  3304  may overlap. In particular, the first display member  3302  may have a tapered region  3504  that defines a substantially straight or flat surface at its terminal end (e.g., leading to a sharp edge). Thus, the tapered region  3504  of the first display member  3302  may not have a fringed profile. On the other hand, the second display member  3304  may have a tapered region  3506  that includes the fringed profile. All or part of the tapered region  3506  and/or the fringed profile may be transparent, to allow underlying pixels of the first display member  3302  (e.g., along the tapered region  3504 ) to be visible through the tapered region  3506  of the second display member  3304 . While  FIGS. 35A-35C  show one example overlapping configuration, other overlapping configurations are also possible, including different amounts of overlap, different taper profiles, overlaps producing non-continuous display seams (e.g., shelfs or steps in the exterior surface of the displays), and the like. 
       FIGS. 36A-36C  show an intersection between the first and second display members  3302 ,  3304 , according to another example joining technique.  FIG. 36A  shows a detail view of a peripheral wall of the display component  3300  corresponding to the area  3306  in  FIG. 33 , and  FIG. 36B  shows a partial cross-sectional view of the display component  3300 , viewed along line F-F in  FIG. 33 . In this example, one or both of the first and second display members  3302 ,  3304  define a scalloped profile along a joining portion or end. The scalloped profile includes projections that may be arranged in an offset, overlapping configuration to help hide or reduce the visibility of a seam  3602  between the first and second display members  3302 ,  3304 , and/or to otherwise create a secure attachment between the display members. As shown in  FIG. 36B , the first and second display members  3302 ,  3304  may be notched in the area of the seam  3602 . The notches may be complementary to allow the first and second display members  3302 ,  3304  to form a single substantially planar and/or continuous surface on the peripheral side of the display component. 
       FIG. 36C  shows a partial exploded or unassembled view of the display component  3300 , further illustrating how the display members  3302 ,  3304  may overlap when joined using the configuration in  FIGS. 36A-36B . As shown, the scalloped profiles may be offset from one another, so that the projections of one of the display members are positioned between two projections on the opposite display member. 
       FIGS. 37A-37B  show an intersection between the first and second display members  3302 ,  3304 , according to another example joining technique.  FIG. 37A  shows a detail view of a peripheral wall of the display component  3300 , corresponding to the area  3306  in  FIG. 33 , and  FIG. 37B  shows a partial cross-sectional view of the display component  3300 , viewed along line F-F in  FIG. 33 . In this example, one or both of the first and second display members  3302 ,  3304  define a straight or flat surface profile along a joining end of the display members, which may produce a substantially straight or linear seam  3702 . As shown in  FIG. 37B , the first and second display members  3302 ,  3304  may be tapered in an overlapping region that corresponds to the seam  3702 . As noted above, the tapered shapes as shown in  FIG. 37B  may avoid or reduce abrupt transitions or discontinuities where one display member overlaps the other, thus reducing the visibility of the seam  3702 . 
       FIG. 38  shows a partial cross-sectional view of the display component  3300 , viewed along line F-F in  FIG. 33 , according to another example joining method. In this example, similar to the example shown in  FIGS. 37A-37B , both the first and the second display members  3302 ,  3304  are tapered in an overlapping region  3802  that corresponds to a seam between the display members. The second display member  3304  may have a transparent region  3804  in the overlapping region  3802 , which may allow images displayed on the portion of the first display member  3302  that underlies the transparent region  3804  to be viewed through the transparent region  3804 . More particularly, a tapered region may not have display elements (e.g., pixels) towards the thinnest end of the taper. Accordingly, by including a transparent region  3804  at or proximate the terminal end of the second display member  3304 , underlying pixels or image forming components of the first display member  3302  may be visible through the transparent region  3804 . 
     Where display members (or portions of a single display member) overlap or are positioned proximate one another, the overall display may be subjected to a calibration procedure to ensure that images or other graphical outputs that span the seam are continuous and seamless. For example, if overlapping displays are misaligned, a portion of a graphical output displayed on one display member may be shifted relative to another portion of the graphical output displayed on another display member. This may be visually unappealing and may reduce the quality and functionality of the device. Accordingly, after a display or electronic device is assembled using multiple display members (e.g., to form a multi-sided display), a calibration routine may be used to programmatically account for physical misalignments. For example, a test image may be displayed on the display. The test image may span multiple display members and/or extend across any seams, folds, overlaps, or other areas of possible misalignment. An imaging system may capture an image of the displayed test image and determine parameters of misalignment between display members (e.g., misalignment angles, misalignment distances, etc.). The imaging system, or any other appropriate system, may then determine programmatic correction parameters that are provided to the device to alter how graphical outputs are displayed, at least in the region of detected misalignment. The process may then be repeated to determine if additional correction parameters are warranted, or if the display is aligned to within an acceptable range. 
     The foregoing displays and display members may include or be associated with touch sensing systems and/or force sensing systems. Such systems may include electrode layers, compressible and/or collapsible layers, processors, and any other suitable components, which may be incorporated with (e.g., attached to) the display members themselves, or placed over, under, or otherwise proximate to a display member and/or a wall of an enclosure through which a display member is viewed. As one example, electrode layers that facilitate capacitive touch sensing (using a self-capacitance scheme, a mutual-capacitance scheme, or any other suitable capacitive sensing technique) may be incorporated with any of the foregoing display members, including those that are visible through the major sides of an enclosure and the peripheral sides of an enclosure. Other types of touch sensing and/or force sensing systems may also or instead be used. Assemblies that include display components and touch and/or force sensing components may be referred to as touchscreen display assemblies. 
     In some cases, electronic device components may require access through a display. For example, cameras, flashes, projectors, microphones, and speakers, among other possible components, may require an opening or other access through the display in order to function effectively.  FIG. 39  shows an example display member  3900  (or a portion of a display member) that includes or defines an opening  3902 . Device components such as a camera  3906  (or other optical sensor), flash  3910  (or other illuminator or projector, such as a micro-dot projector for facial or other biometric recognition), and an audio component  3908  (such as a microphone, speaker, or the like) may be positioned in or otherwise configured to communicate through the opening  3902 . The components may be positioned in a carrier  3904 , which may have a size and shape that corresponds to the opening  3902 . Alternatively, the carrier  3904  may represent an ink, mask, or other material or component that covers the opening and prevents internal components from being visible through the opening  3902 . 
     While  FIG. 39  shows a single opening, in some cases a display may include multiple openings, such as one opening each for the camera  3906 , flash  3910 , and audio component  3908  (or other components). Moreover, in embodiments where a device includes such components at both ends of a device (e.g., proximate both a top and bottom of the device), the display may include an additional opening and additional corresponding device components, all of which may appear substantially identical to the opening and the components illustrated in  FIG. 39  but positioned at a different end of the display member  3900 . 
     As described herein, some glass enclosures may be formed to be substantially completely enclosed, and in some cases may be formed so that substantially all of the sides are a single glass component. In such cases, some access must be provided to the interior volume of the enclosure in order to allow internal device components to be inserted into the interior volume.  FIG. 40  shows an example assembly process by which internal components may be introduced into an interior volume of a glass enclosure. 
     In particular,  FIG. 40  shows a glass enclosure  4000  that includes an opening  4001  defined in one of the peripheral sides of the glass enclosure  4000 . The glass enclosure  4000  may be a monolithic or unitary component (e.g., a single piece of glass that defines at least a portion of each of six sides of the enclosure), or it may have been assembled by joining multiple glass members. As shown in  FIG. 40 , a flexible display member  4002 , which may represent any of the flexible display members shown or described herein, is being collapsed to fit through the opening  4001 . Once through the opening  4001 , the flexible display member  4002  is un-collapsed or un-folded to an original or desired size and configuration. Multiple display members may be inserted into the glass enclosure  4000  in a similar manner, and positioned at target locations within the glass enclosure  4000  to form a multi-sided display component, such as any of the display components shown or described herein. 
     In some cases, all of the components of the device are suitably sized and/or shaped to be inserted through the opening  4001 , including batteries, processors, circuit boards, memory, sensors, cameras, projectors, microphones, speakers, support frames or structures, and the like. For example,  FIG. 40  shows an example support frame  4005  that includes a main strut  4004  and end struts  4006  that can move or flex relative to the main strut  4004  (e.g., along arrows  4008 ) so that the support frame  4005  may be inserted into the interior volume of the enclosure  4000  through the opening  4001 . Once inside the enclosure  4000 , the end struts  4006  may be unfolded into their final positions (e.g., perpendicular to the main strut  4004 ).  FIG. 40  also shows example battery modules  4010  that may be sized to fit through the opening  4001 . The battery modules  4010  may be connected together once inside the enclosure  4000  to supply power to the electronic device.  FIG. 40  also shows a device module  4012 , which represents other internal components of a device, such as one or more circuit boards, processors, structural members, frames, audio modules (e.g., speakers, speaker chambers, microphones, transducers), cameras, touch and/or force sensors, wireless charging components, antennas, memory modules, haptic actuators, or the like. 
     In some cases, electronic devices using enclosures as described herein may include internal structural supports or frames. These supports may provide several functions. For example, they may help provide structural rigidity, stiffness, and/or strength to the device. They may also form mounting surfaces for internal components. They may also define support structures or surfaces on which flexible display members may be placed, and which may impart a shape to flexible display members. 
       FIG. 41  shows a cross-sectional exploded view of an example device  4100 , showing another technique for assembling and/or arranging device components inside a glass enclosure. The glass enclosure may include a first glass member  4102  and a second glass member  4104 , each defining a major side and a portion of the peripheral sides of the enclosure (similar to the enclosure shown in  FIG. 16A , above). Before the first and second glass members  4102 ,  4104  are bonded together or otherwise joined, components may be arranged between the first and second glass members  4102 ,  4104 . For example, the components may be placed in and/or secured to one or both of the first and second glass members  4102 ,  4104 . 
     As a non-limiting example, a first display member  4106  may be positioned in the partial cavity defined by the first glass member  4102 , and optionally secured to the first glass member  4102 . The first display member  4106  may be configured to transmit graphical output through all (or in some cases a subset) of the sides of the first glass member  4102 . A circuit board  4110  may also be positioned in the partial cavity defined by the first glass member  4102  and below the first display member  4106 . The circuit board  4110  may include any or all of the main device components of the device, including processors, structural members, frames, audio modules (e.g., speakers, speaker chambers, microphones, transducers), cameras, touch and/or force sensors, wireless charging components, antennas, memory modules, haptic actuators, or the like. 
     A second display member  4108  may be positioned in the partial cavity defined by the second glass member  4104 , and optionally secured to the second glass member  4104 . The second display member  4108  may be configured to transmit graphical output through all (or in some cases a subset) of the sides of the second glass member  4104 . A battery  4112  may also be positioned in the partial cavity defined by the second glass member  4104  and above the second display member  4108 . The battery  4112 , circuit board  4110 , and first and second display members  4106 ,  4108  may be electrically interconnected in any suitable way, and the glass members  4102 ,  4104  may thereafter be secured to one other to define a device having an enclosure with glass defining substantially all exterior surfaces. 
       FIG. 42A  shows a perspective view of an example support structure  4200  that may be positioned inside an enclosure.  FIG. 42B  shows a cross-sectional view of the support structure  4200 , viewed along line G-G in  FIG. 42A . The support structure  4200  includes a frame  4202  and peripheral supports  4204 . The peripheral supports  4204  may be curved or otherwise conform to or follow a rounded or curved shape of the interior surface of a peripheral side of an enclosure (e.g., the enclosure  102 ,  FIGS. 1A-1B ). A flexible display member (e.g., the third display member  3106 ,  FIG. 31A ) may be supported by, and optionally in direct contact with, the peripheral supports  4204 . Electronic device components may be coupled to the frame  4202 , including but not limited to circuit boards, sensors, processors, memory, batteries, and the like. The frame  4202  may define an opening  4206  that allows components to be placed in the opening and/or allows electrical and/or physical interconnections between components that are on opposite sides of the frame  4202 . 
     All or some of the support structure  4200  may be electrically active or otherwise part of an electrical circuit. For example, the support structure  4200  may be formed from or include conductive materials (e.g., metal, carbon fiber), and may form or be part of an electrical ground for the device. In some cases, all or some of the support structure  4200  may be part of an antenna circuit. For example, portions of the support structure  4200 , such as the peripheral supports  4204 , may be configured to transmit and/or receive wireless signals (e.g., they may act as a radiator or receiver of radio frequency signals). 
     The support structure  4200  may be formed of or include any suitable material, such as plastic, carbon fiber, rubber, metal (e.g., aluminum, stainless steel), ceramic, glass, composite materials, or the like. Moreover, the support structure  4200  may be collapsible so that its outer dimensions can be reduced to fit through an opening in an enclosure (e.g., the opening  4001 ,  FIG. 40 ). For example, the support structure  4200  may be formed of or include flexible materials that allow the peripheral supports  4204 , for example, to be folded against the frame  4202 . As another example, the support structure  4200  may include hinges, living hinges, or other mechanical joints that allow the support structure  4200  to be at least partially collapsed for insertion into an enclosure and then expanded to a desired final configuration within the enclosure. 
       FIG. 43A  shows a perspective view of another example support structure  4300  that may be inserted into or assembled inside of a glass enclosure. The support structure  4300  may be used to support internal electronic device components, and/or to provide structural rigidity, stiffness, and/or strength to the enclosure and the device overall. The support structure  4300  may include a structure of rods, beams, or other elongated members that are coupled to one another to form a substantially rectangular frame. Corner supports  4302  (as well as the remaining portions of the support structure  4300 , may have any suitable shape. As shown, they are substantially straight (e.g., linear) rods. In other cases, they may be curved, such as to conform to or track a shape of an interior surface of a glass enclosure. The support structure  4300  may be formed of or include flexible members or materials (or hinges or other structures) to allow the support structure  4300  to be at least partially collapsed for insertion into an enclosure, and then expanded to a desired final configuration within the enclosure. Alternatively, the support structure  4300  may be assembled within an enclosure from constituent components or parts. 
       FIG. 43B  is a perspective view of an example support structure  4310  that may be used with a device that has a cylindrical shape (e.g., the device  420 ,  FIG. 4C ). The support structure  4310  is similar to the support structure  4300 , but has a different form factor to accommodate a differently shaped enclosure. 
     The support structure  4310  includes support members  4314  and base supports  4316 ,  4318 . A display (e.g., the display  2620 ,  FIGS. 26D-26F ) may be supported by, and optionally in direct contact with, the support members  4312 . Electronic device components may also be coupled to or supported by the support members  4312 , including but not limited to circuit boards, sensors, processors, memory, batteries, and the like. The base supports  4316 ,  4318  may have a shape corresponding to the bases of a cylindrical enclosure (shown here as circular, but they may have different shapes depending on the particular shape of the enclosure). The base supports  4316 ,  4318  may support portions of a display that are viewable through the bases of a cylindrical enclosure. The base supports  4316 ,  4318  may include curved portions that may contact or otherwise provide structural support to a display, and may in fact maintain a display, or a portion thereof, in a particular curved shape. Other aspects of the support structure  4300  described above are likewise applicable to the support structure  4310 , including suitable materials and the collapsibility of the support structure for assembly. 
       FIG. 44A  is a representative cross-sectional view of an electronic device  4400 , corresponding to a view along line G-G in  FIG. 42A , showing one example internal arrangement of components of the device  4400 . The device  4400  includes a glass enclosure  4402 , which may correspond to any of the enclosures shown or described herein. The glass enclosure  4402  may define first and second major sides  4401 ,  4403 , and peripheral sides  4405 . The device  4400  may include a mutli-sided display, which may include a first display  4408  (which may be substantially planar) that is visible through the first major side  4401  and a second display  4406  (which may be substantially planar) that is visible through the second major side  4403 . The multi-sided display may also include a third display  4404  (similar to the display  3106 ,  FIGS. 31A-31B ) that may be curved and is visible through the peripheral sides  4405 . The displays  4404 ,  4406 , and  4408  may be rigid or flexible displays, as described herein, and outer surfaces of the displays may be in direct contact with the interior surface of the enclosure  4402  (as shown), or they may be set apart from the enclosure by a void or by another transparent component. Moreover, while shown as three separate display members, the displays  4404 ,  4406 , and  4408  may instead be more or fewer display members (e.g., they may all be part of a single contiguous display member that is folded or otherwise formed to be visible through the major and peripheral sides of the enclosure). Where the displays  4404 ,  4406 , and  4408  are multiple display members, they may be joined together as described herein. 
     The device  4400  may also include force and/or touch sensing components  4409  between the displays  4404 ,  4406 ,  4408  and the glass enclosure  4402  (or otherwise integrated with the displays  4404 ,  4406 ,  4408 ). The force and/or touch sensing components  4409  may include any suitable components that, alone or with other components, facilitate the detection of touch and/or force inputs on the exterior surface of the glass enclosure  4402 . The force and/or touch sensing components  4409  may include electrode layers, compliant or compressive layers, capacitive sensing components, resistive sensing components, or the like. 
     The device  4400  may also include a support structure  4410 . The support structure  4410  may resemble the support structure  4200  described with respect to  FIGS. 42A-42B . The support structure  4410  may have curved peripheral supports that may support the third display  4404 , and in the case where the third display  4404  is a flexible display, may impart a desired shape to the display  4404 . 
     The device  4400  may also include a first module  4414  attached to or otherwise supported by the support structure  4410  on a first side of the support structure  4410 , and a second module  4412  attached to or otherwise supported by the support structure  4410  on a second side of the support structure  4410  opposite the first side. The first module  4414  may include circuits, processors, memory, circuit boards, sensors, chipsets, and the like, and the second module  4412  may include batteries (though these are merely example components and positions for such components). One or more of the displays may be coupled to the first module  4414  via a connector  4418 . As noted above, these components may be positioned inside the device by inserting them into a substantially completed enclosure (e.g., through an opening in an otherwise enclosed six-sided enclosure) and assembling them while they are inside the enclosure, or by building the enclosure around the components (e.g., by joining two enclosure members together around an already assembled set of internal components. 
     As shown in  FIG. 44A , the device  4400  may include interstitial voids  4416  that are not occupied by device components. These voids  4416  may be filled with air or another gas. In some cases, the air or other gas is at ambient pressure. In other cases, the enclosure  4402  may have a different pressure than the external environment. For example, air or another gas or fluid may be introduced into the voids  4416  at an above-ambient pressure, and the enclosure  4402  may thereafter be sealed to trap the gas or fluid in the enclosure  4402 . The internal pressure from the gas may increase the strength, stiffness, rigidity, resistance to damage, or other physical properties of the overall device  4400 . 
       FIG. 44B  shows the same cross-section of the device  4400 , but instead of a void that is filled with gas at or above an ambient pressure, the void space is at least partially filled with a potting or encapsulating material  4420 . The encapsulating material  4420  may be a foam (e.g., an expanding foam), a liquid (e.g., a liquid dielectric), a polymer, or any other suitable material. The encapsulating material  4420  may provide additional structural rigidity, stiffness, and/or strength to the device  4400 . For example, the encapsulating material  4420  may apply an outward pressure on the displays that forces the displays against the interior surfaces of the enclosure. The encapsulating material  4420  may also prevent or limit movement of internal components relative to the support structure and/or one another. 
     As described above, glass enclosures may lack physical buttons, keys, switches, or other physical affordances that may be found on conventional electronic devices. Instead of such physical affordances, devices with glass enclosures as described herein may use other techniques to provide visual and/or tactile queues to a user regarding the location, size, and/or function of certain input regions. One such technique is to form regions of different textures on exterior surfaces of the enclosure. 
       FIG. 45A  shows an example glass enclosure  4500  that defines a first major side  4504 , a second major side opposite the first major side, and a peripheral side  4503 . As noted above, affordances such as volume buttons, power buttons, ring/silent buttons, or the like may be positioned on the peripheral side  4503  of a device enclosure. In order to improve the tactile feel of the affordances, regions  4502  of the peripheral side  4503  that correspond to the affordances may be textured to provide a tactilely detectable difference between the regions  4502  and other surfaces of the enclosure  4500  (e.g., the first and second major sides). The surface texture of the regions  4502  may be formed in any suitable way. For example, the regions  4502  may be abrasive blasted, etched (e.g., chemical etching, laser etching, etc.), ground, lapped, machined, or the like. In some cases, a coating or film may be applied to the peripheral side  4503  to define the regions  4502 . Even when the regions  4502  are textured, they may remain sufficiently transparent to allow images or components under the regions  4502  to be visible. In some cases the regions  4502  may be visually indistinguishable (with an unaided eye) from other regions of the enclosure, despite having a different tactile feel. Accordingly, the dynamic nature of a multi-sided, touch- and/or force-sensitive display may be maintained while also adding the advantages of the differences in texture. 
     In some cases the regions  4502  have a greater surface roughness than other regions of the enclosure  4500 , such as the major sides of the enclosure. This may be achieved, for example, using one of the aforementioned texturing processes. In other cases, the regions  4502  may produce different tactile responses using other phenomena, such as using different oleophobic coatings, different insulating or conductive coatings, different glass compositions, or any other suitable technique. 
     The regions  4502  may correspond to graphical outputs presented on a display underlying the peripheral side  4503 , and the regions  4502  may be touch and/or force sensitive (e.g., using touch- and/or force-sensing systems) to detect user selections or actuations of the regions  4502 . In other cases, there may be no display under the textured regions  4502 . For example, a static image, a light, or another indicator may be positioned below the textured regions  4502  to visually indicate that the regions  4502  are affordances that control an operation or function of a device. 
       FIG. 45B  shows an example glass enclosure  4510  having textured regions similar to those described with respect to the enclosure  4500 , but applied to an enclosure having a different shape. In particular, the glass enclosure  4510  has a cylindrical shape (and may be an embodiment of the enclosure  422  shown in  FIG. 4C ). The enclosure  4510  defines a cylindrical wall  4512  and first and second bases  4514 ,  4516 , respectively. The enclosure  4510  also defines a first curved transition region  4517  between the cylindrical wall  4512  and the first base  4514  and a second curved transition region  4519  between the cylindrical wall  4512  and the second base  4516 . As noted above, affordances such as volume buttons, power buttons, ring/silent buttons, or the like may be positioned at various locations on an enclosure. In order to improve the tactile feel of the affordances, regions  4518  of the enclosure  4510  that correspond to the affordances may be textured to provide a tactilely detectable difference between the regions  4518  and other surfaces of the enclosure  4510  (e.g., the cylindrical wall  4512  and the first and second bases  4514 ,  4516 ). The surface texture of the regions  4518  may be formed in any suitable way, such as those described above with respect to the regions  4502 . Aspects of the regions  4502  described above apply equally or by analogy to the regions  4518 , and will not be repeated here. 
       FIG. 46  shows another example enclosure  4600  that has a textured region. In this example, the textured region extends over substantially all of the peripheral sides  4602 , and has a different tactile feel than the major sides (e.g., the first major side  4604 ). As noted above, the textured region along the peripheral sides  4602  may represent any difference in tactile feel between the peripheral sides  4602  and the major sides. 
     In cases where the peripheral sides are substantially completely textured, the texturing may help to hide or reduce the visibility of seams or discontinuities between enclosure members or display members. Further, in cases where underlying displays are visible through a textured surface, texturing substantially the entire exterior surface of the peripheral wall may reinforce functional distinctions between different display regions. For example, a device may be configured to not use peripheral displays for display of video or photographs (which may be primarily or exclusively viewable via a major side). Thus, visible texturing on the peripheral sides may reinforce the distinction between the types of graphical outputs visible on the peripheral sides (e.g., affordances, weather icons, device status icons, text, etc.) and the types of graphical outputs that may be displayed on the major sides (e.g., primary GUI screens, text input screens, videos, photographs, webpages, etc.). 
       FIG. 47  shows another example enclosure  4700  that has a textured region. In this example, the textured region extends over only a portion of the peripheral sides  4702  of the enclosure  4700 . For example, as shown, the textured region  4706  extends at or about a middle of the peripheral sides  4702  of the enclosure  4700  (e.g., a point at approximately 50% of the thickness of the enclosure  4700 ). As noted above, the texturing may be aligned with or occlude underlying seams or discontinuities between enclosure members or display members. 
       FIG. 48  shows another example enclosure  4800  that has a textured region. In this example, the corner regions  4802  of the enclosure  4800  may be textured or otherwise have a different tactile feel (and optionally different appearance) than other portions of the peripheral sides  4803  and/or the major sides (e.g., the first major side  4804 ). Texturing the corner regions  4802  may provide similar advantages to those described above, including hiding seams between enclosure members, hiding or covering seams, gaps, or other irregularities between display members, or the like. In some cases, as described herein, corner regions may be associated with light sources that do not or are not intended to form distinct images. These corner-positioned light sources may be simple light sources such as light emitting diodes, or regions of a display that are not sufficiently aligned or configured to produce visually appealing images. In such cases, texturing the corner regions  4802  may diffuse the light produced by the light sources to produce an illumination that appears even or homogenous across the corner. Further, the texturing or other treatment may be sufficiently opaque to occlude any unsightly components, such as gaps, seams, or openings between display members or unaligned portion of display members (such as may occur in the corner regions  3108  of the flexible display member shown in  FIGS. 31A-31B . 
       FIG. 49  shows an example device  4900  that includes a glass enclosure  4902 , which defines a first major side  4904  (and a second major side opposite the first major side  4904 ), and peripheral sides  4906 . The device  4900  also includes a multi-sided display  4903  that displays images at least through the major sides and the peripheral sides  4906 . The display  4903  may have a first pixel configuration (e.g., resolution, pixel size, pixel type, etc.) along the major sides and the peripheral sides, and a second pixel configuration along the corner regions  4908 . For example, the corner regions  4908  may have a lower resolution (e.g., pixels-per-inch) than the portions of the display  4903  that are visible through the major and peripheral sides. In such cases, the corner regions  4908  may be used to display lower-resolution images than other portions of the display, or even to display only colors (e.g., with no discernable image). In yet other examples, the corner regions  4908  may not have a conventional pixelated display, but instead may have a single light emitting diode (LED) or other light source (with optional light diffusers) that simply produces a substantially homogenous output of light. 
     Different colors may be displayed on the corner regions  4908  for various reasons. For example, different colors may be displayed based on different operational states of the device. White illuminated corner regions  4908  (optionally flashing or pulsing), for example, may indicate an incoming call, text message, or email. Red illuminated corner regions  4908  may indicate that a voice call is currently active. Green illuminated corner regions  4908  may indicate that the device is fully charged, and yellow illuminated corner regions  4908  may indicate that the battery of the device is low. In some cases, the corner regions  4908  are illuminated with a color that is based on what is being displayed on the major or peripheral sides. For example, if a predominantly blue image is being displayed on the first major side  4904 , the corner regions  4908  may be illuminated blue. Of course, the foregoing examples are merely illustrative, and other colors may be mapped to these (or other) states or functions. 
     As described herein, electronic devices such as mobile phones may require or benefit from an optical path between the exterior environment and certain internal components such as cameras, sensors, projectors, flashes, or the like. For example, a camera inside an electronic device housing needs an optical path in order to capture images outside the electronic device. Similarly, an audio opening may be used to allow air to pass between the exterior environment and internal audio components, such as microphones and speakers. Accordingly, an enclosure and/or a display of a device with a glass enclosure as described herein may include one or more apertures or openings, which may facilitate optical communication and sound transmission, as well as other functions such as charging and reception.  FIG. 50  depicts an example electronic device  5000  that includes a glass enclosure  5002  and a display  5016  (which may be similar to the corresponding components described with reference to  FIGS. 1A-1B ). The display  5016  includes or defines an area  5018 , which may include one or more openings through a portion of the display  5016  that allows communication of sound and light through the display  5016 . The openings may surround or be aligned with components such as one or more cameras (e.g.,  5020 ), projectors (e.g.,  5022 ), audio components (e.g.,  5024 ), biometric sensors, image sensors, and the like. The enclosure  5002  may define an opening  5026  corresponding to and/or aligned with one or more of the components in the area  5018 . For example, the opening  5026  may overlie the audio component  5024 , such as a microphone, speaker, or both, to allow sound to pass into and/or out of the device  5000  without having to pass through the glass medium of the enclosure  5002 . A mesh, screen, or other protective member may be positioned in the opening  5026  to prevent ingress of liquids, dust, or other debris or contaminants. 
       FIG. 50  shows one area  5018  on one major side of the device. In some cases, a similar or identical area  5018 , and similar or identical components associated with that area, may be positioned on an opposite side of the device. Accordingly, either major side of the device  5000  may be used as the primary interface surface at any given time, further reinforcing the symmetrical configuration of the device  5000 .  FIG. 50  shows the area  5018  located proximate a top of the first major side. In some cases, however, the device  5000  includes two similar or identical areas, along with similar or identical components, on each major side (e.g., proximate the top and bottom, respectively) of each major side. With such an arrangement, the distinction between the top and bottom of the device may further be blurred or erased, as a user can pick up the device  5000  in any manner or orientation and the device  5000  will have appropriately located microphones and speakers (e.g., for voice calls). 
       FIGS. 51A-51B  depict another example electronic device  5100  that includes a glass enclosure  5102  and a display  5116  (which may be similar to the corresponding components described with reference to  FIGS. 1A-1B ), showing another example configuration in which openings allow sound and/or light to pass in and out of the enclosure  5102 . In particular, an opening  5118  (which may be a continuous channel) may wrap at least partially around the device  5100  from a first major side  5104  to a second major side  5106 . For example, the opening  5118  may have a first opening portion through the first major side  5104 , a second opening portion through the peripheral side  5108 , and a third opening portion through the second major side  5106 . 
     Speakers and/or microphones may be aligned with or otherwise in communication with the opening  5118  to receive and/or emit sounds through the opening  5118 . A mesh, screen, or other protective member may be positioned in the opening  5118  to allow sound to enter and escape the enclosure  5102  while also preventing ingress of liquids, dust, or other debris or contaminants into the enclosure  5102 . Because the opening  5118  wraps around the enclosure  5102  (e.g., extending along a peripheral side  5108 ) to form openings in both the first and second major sides  5104 ,  5106 , both the first and second major sides  5104 ,  5106  may appear visually identical, further blurring or erasing the distinction between the conventional notions of a device with a different front and back. 
     In some cases, the device  5100  may also include an additional opening  5120 , which may be substantially identical to the opening  5118 , but positioned on an opposite end of the device  5100  (and optionally extending along a peripheral side  5110 ). As described above with respect to the openings in  FIG. 50 , positioning openings  5118  and  5120  proximate both ends of the device  5100  further reinforces the symmetrical appearance and functionality of the device  5100 , as the device  5100  may visually appear and functionally operate as though there is no established “top” or “bottom” of the device  5100 . Accordingly, the device may provide maximum flexibility in operation and use of the device  5100 . 
     The display  5116  may define or include openings through at least a component of the display  5116  to allow for components to input and/or output light, sound, etc., via the openings  5118 ,  5120 . The openings may be formed in otherwise contiguous surfaces of a display, or they may be formed by leaving gaps at seams or joints between displays or between adjacent portions of a single display. Such openings may correspond to or be aligned with cameras, speakers, microphones, sensors, projectors, flashes, or the like. 
     As described herein, devices with multi-sided displays that are visible through as many as all sides of the device may be configured to be usable in multiple different orientations. For example, in some conventional devices, the device has a dedicated top, bottom, front, and back. Even in cases where a conventional single-sided display can re-orient its graphical output when a device is rotated between a portrait orientation and a landscape orientation, such devices still have other constraints that limit the availability of the device&#39;s functions. For example, the speaker and microphone of a conventional phone are fixed in position, and even a phone with a graphical user interface that can be reoriented (e.g., between landscape and portrait) cannot be conveniently used to make telephone calls in an upside-down orientation, because the microphone and speaker will not be properly aligned with a user&#39;s mouth and ear. 
     Described herein are devices that may substantially lack hardware and/or user-interface cardinality. More particularly, such devices may be able to be picked up and/or held in any orientation, and the device will provide identical or substantially identical functionality.  FIGS. 52A-53C  illustrate example use cases, demonstrating how a device&#39;s user interface may dynamically react and how the symmetrical hardware configuration can provide equivalent functionality regardless of how it is being held or used. 
       FIG. 52A  shows a user about to grasp a device  5200  that is resting on a surface (e.g., a table). As shown, the device  5200  is displaying a user interface  5201  in a particular orientation, with a “top” of the user interface nearest the first side  5202  of the device  5200 . As the user picks up the device  5200 , the device  5200  detects that it is being held or is being moved in such a way that a second side  5204  corresponds to (or is likely to correspond to) the “top” of the device (as viewed by the user). The device  5200  may detect this situation in any suitable way, such as using an accelerometer, camera, compass, or any other suitable device or combination of devices. More particularly, the device  5200  may use an optical sensing system (such as a biometric sensing system) to detect a relative position and/or orientation of the user&#39;s face with respect to the device  5200 . The device  5200  may also determine grasp information that is indicative or suggestive of how it is being grasped (e.g., based on the location of a user&#39;s fingers, palm, thumb, etc., as determined by touch and/or force sensors), and use the grasp information to determine how to orient the user interface. 
       FIG. 52B  shows the device  5200  while it is being rotated by the user. As shown, in response to the detection or prediction that the second side  5204  of the device  5200  is acting as the “top” of the device (from the user&#39;s perspective), the user interface is rotating to position the top of the user interface proximate the second side  5204  of the device  5200 .  FIG. 52C  shows the device  5200  after the user interface has been repositioned in response to the determined orientation (relative to the user or in absolute terms). 
     In addition to the reorientation of the user interface in response to how a user is grasping, holding, looking at, or otherwise interacting with a device, the hardware symmetry of the device allows the device to provide identical or substantially identical functionality in any position or orientation. For example, as shown in  FIG. 52A , the device  5200  includes a first hardware component  5206  positioned proximate the first side of the device  5202 , and a second hardware component  5208  positioned proximate the second side of the device  5204 . The first and second hardware components  5206 ,  5208  may have at least some components in common, or may otherwise provide the same or similar functionality. For example, the first and second hardware components  5206 ,  5208  may each have a speaker and a microphone to facilitate voice calls via the device  5200  (e.g., to provide audio output to the user&#39;s ear and receive audio input from the user&#39;s mouth). In  FIG. 52A , the first hardware component  5206  is positioned so that, were the user to pick up the device  5200  without rotating the device, the first hardware component  5206  would position a speaker proximate the user&#39;s ear and the second hardware component  5208  would position a microphone proximate the user&#39;s mouth. As shown in  FIG. 52C , the second hardware component  5208  is now positioned at what would be conventionally understood as the “top” of the device (based on the manner in which the device is being used and/or held). Because the first and second hardware components  5206 ,  5208  may each have a speaker and a microphone, the second hardware component  5208  positions a speaker proximate the user&#39;s ear and the first hardware component  5206  positions a microphone proximate the user&#39;s mouth. 
     The device  5200  may also select which hardware components to use and/or activate based on the determined orientation. For example, when the device  5200  determines that the second side  5204  is being used as the conventional “top,” and a voice call is active, the device  5200  may activate a speaker associated with the second hardware component  5208  and deactivate a microphone associated with the second hardware component  5208 . The device  5200  may also activate a microphone associated with the first hardware component  5206  and deactivate a speaker associated with the first hardware component  5206 . In cases where the device  5200  includes different sets of speakers and/or microphones on both major sides of the device, the speakers and/or microphones on the side of the device that is being used as a conventional “back” of the device may be deactivated. In other cases, any microphone that is not positioned immediately proximate the user&#39;s mouth (or that would not be the closest to the user&#39;s mouth during a conventional voice call) may be activated. Such auxiliary microphones may be used to help pick up the user&#39;s voice, and/or to help cancel ambient or other unwanted noise from the primary microphone (e.g., the microphone closest the user&#39;s mouth). 
       FIGS. 53A-53C  illustrate another example of how the device  5200  may provide substantially identical functionality in multiple orientations, showing how the device  5200  may dynamically select a major side to act as the “front” of the device, and how the hardware symmetry of the device  5200  may provide the same functions regardless of which side is acting as the “front” of the device. 
       FIG. 53A  shows the user grasping the device  5200  that is resting on a surface (e.g., a table), prior to changing the orientation of the device  5200 . As shown, the device  5200  is displaying the user interface  5201  on a first major side  5210  of the device  5200 . As the user picks up the device  5200 , the device  5200  detects that it is being held or is being moved in such a way that a second major side  5212  ( FIG. 53B ) corresponds to (or is likely to correspond to) the “front” of the device (as viewed by the user). The device  5200  may detect this situation in any suitable way, such as using an accelerometer, camera, compass, touch and/or force sensors, or any other suitable device or combination of devices, as described above with respect to  FIG. 52A . 
       FIG. 53B  shows the device  5200  while it is being flipped by the user. As shown, in response to the detection or prediction that the second major side  5212  of the device  5200  is acting as the “front” of the device (from the user&#39;s perspective), the user interface is translating to position the user interface on the second major side  5212  of the device  5200 .  FIG. 53C  shows the device  5200  after the user interface has been repositioned in response to the determined orientation (relative to the user or in absolute terms). 
     As discussed with reference to  FIGS. 52A-52C , the hardware symmetry of the device  5200  allows the device to provide identical or substantially identical functionality in any position or orientation. For example, as noted above, the device  5200  includes a first hardware component  5206  positioned proximate the first side of the device  5202 , and a second hardware component  5208  positioned proximate the second side of the device  5204 . As shown in  FIGS. 53B-53C , the device  5200  also includes a third hardware component  5214  positioned proximate the first side of the device  5202  and a fourth hardware component  5216  positioned proximate the second side of the device  5204 . When the device  5200  determines that the second major side  5212  is being used as the “front” of the device, the device  5200  may select the third and fourth hardware components  5214 ,  5216  to provide certain functionality, such as audio input and output during voice calls. The first and second hardware components  5206 ,  5208  may be deactivated or may be used to provide other functionality. 
     In addition to selecting the third and fourth hardware components  5214 ,  5216  in response to determining that the second major side  5212  is acting as the “front” of the device  5200 , the device  5200  may further select which functionality will be provided by the third and fourth hardware components  5214 ,  5216  based on which side is being used as the “top” of the device  5200 . For example, if the third hardware component  5214  is nearest the “top” of the device  5200 , as viewed by the user, the third hardware component  5214  may be selected to provide audio output and the fourth hardware component  5216  may be selected to provide audio input. 
     While the foregoing descriptions relate to assigning audio input and output functions for voice calls to certain hardware components, this is merely an example of the ways in which a device may assign components of a symmetrical hardware arrangement, and other assignments are possible. For example, in response to determining which major side of a device is acting as a “front” of the device, the device may assign the hardware components associated with the “front” of the device to voice-call type functions (as described above), and may assign the hardware components associated with the “back” of the device to other functions, such as audio output (e.g., using the speakers as stereo speakers for music), audio input for noise cancelling (e.g., using the microphones to capture ambient or other external noise), and the like. Of course, as noted above, such assignments may be dynamically established and may be changed based on changes to the device&#39;s orientation and/or how the device is being held or used. 
     The user interface animations shown in  FIGS. 52A-53C  are merely for the purposes of illustration. Such animations are not necessarily displayed on the display during the manipulations shown in the figures. They nevertheless illustrate how the device may programmatically reorient itself based on its absolute and/or relative orientation. In some cases, however, the illustrated animations or other animations may be displayed during the manipulations shown (or other manipulations that result in the device re-orienting or re-positioning the user interface). 
     The foregoing examples describe enclosure and display technologies as applied to smartphones and tablet computers. However, the features and concepts described herein may be used with other types of electronic devices as well, including but not limited to watches, health and/or biometric monitors, or other portable and/or wearable electronic devices.  FIG. 54  illustrates an example wearable electronic device, and specifically a watch  5400 , that includes an enclosure  5401  in which a first major side  5414  (e.g., the face of the watch), a second major side  5413  (e.g., the wrist-facing side of the watch), and substantially all of the peripheral sides are glass. The watch  5400  may also include a watch band  5408  attached to the enclosure  5401 . The watch band  5408  may be permanently attached to the enclosure  5401 , or it may be removable such that it can be replaced and/or swapped with other bands. 
     The enclosure  5401  may include a first glass member  5402  and a second glass member  5404 . The first glass member  5402  defines the first major side  5414  and a portion of each of the peripheral sides of the enclosure  5401 . The second glass member  5404  defines the second major side  5413  and another portion of each of the peripheral sides. The enclosure  5401  also includes an intermediate member  5406  between the first and second glass members  5402 ,  5404 . The intermediate member  5406  may be metal, plastic, glass, or another suitable material, and may serve as a structural member of the device and may facilitate bonding between the first and second glass members  5402 ,  5404 . Alternatively, the intermediate member may be cosmetic, and may contribute little or no structural strength or rigidity to the enclosure. The first and second glass members  5402 ,  5404  may be secured to the intermediate member  5406  in any suitable way, including mechanical interlocks, adhesives, epoxies, ultrasonic welding, frit bonding, or the like. Many of the enclosure forming techniques and structures described herein with respect to other examples may be used to form enclosure  5401  of  FIG. 54 . Relevant description of such techniques and structures are not repeated in order to reduce redundancy. 
     The watch band  5408  may attach to the enclosure  5401  via the intermediate member  5406 . In cases where the watch band  5408  is not removable, the watch band  5408  may be permanently attached to the intermediate member  5406 . In other cases, such as where the watch band  5408  is removably coupled to the enclosure  5401 , the intermediate member  5406  may include or define part of a channel, lug, or other feature or mechanism with which the watch band  5408  engages to removably couple the watch band  5408  to the enclosure  5401 . 
     As with the other devices described herein, the watch  5400  may include one or more displays that are visible through all or some of the first glass member  5402  and through all or some of the second glass member  5404 , including through the peripheral sides of the enclosure  5401 . Additionally, the watch  5400  may include touch- and/or force-sensing systems that detect inputs applied to the major sides and/or the peripheral sides (or portions thereof) of the watch  5400 . Such touch- and/or force-sensing systems may operate in accordance with capacitive sensing, inductive sensing, optical sensing, or other sensing techniques. The watch may be configured to produce a graphical output that is controlled or performed in accordance with instructions or programs executed by a processor and may be generally referred to as a smart watch, wearable computer, or other similar type of electronic device. 
     Also, similar to other examples provided herein, the graphical output of the display may be modified in accordance with an orientation of the watch  5400 . Additionally, the graphical output and/or other operational characteristics of the watch  5400  may be modified in response to the watch  5400  being worn on a right wrist, a left wrist, resting on a surface, or mounted in a docking station or stand. The watch  5400  may modify the graphical output and/or other operational characteristics of the watch  5400  automatically, based sensor input(s), detected locations, or the like. For example, when a user lifts his or her wrist to view the watch, the watch  5400  may detect the motion and in response output a first type of graphical output (e.g., a watch face viewable through the first major side defined by the first glass member  5402 ). When the user places the watch  5400  on a night stand, desk, or other surface (and optionally on a charger), the watch  5400  may output a second type of graphical output (e.g., the time and an alarm status on a peripheral side of the watch  5400 ). Other types of graphical outputs and triggers (e.g., events, locations, sensed motion, etc.) are also contemplated. For example, the peripheral sides may be illuminated (e.g., with a solid color) to indicate events or provide other notifications (e.g., when a message has been received, when an alarm or timer has expired, or the like). 
     In some embodiments, graphical output from the display may be viewable through one or more additional faces depending on a wearing condition (left or right wrist), an orientation of the device, or placement in a docking station or stand. In some instances, the watch  5400  may be reversible and graphical output may be displayed through either of the major sides in accordance with a wearing condition. 
     Similar to other examples provided herein, the watch  5400  may provide graphical outputs that are viewable through the peripheral sides. Such graphical outputs may change based on a mode of the device or a manner in which the device is being used. For example, the graphical outputs on the peripheral sides may change in response to a user changing a user interface scheme, or in response to the watch detecting that the user is performing a particular activity. As one example of the former case, a user may manually switch the watch  5400  from a “home” user interface scheme to a “travel” user interface scheme. This may result in the graphical output on the peripheral sides transitioning from displaying weather information to displaying time zone information. Of course, other types of schemes and graphical outputs are also contemplated. As an example of the latter case, the watch  5400  may detect when a user is working out (e.g., based on biometric sensor data, accelerometer data, or the like) and automatically transition to a workout scheme in which heart rate, running/walking pace, elapsed time, or other information may be displayed on one or more peripheral sides. 
     Affordances may also be displayed on the peripheral sides of the watch  5400 . For example, affordances such as volume buttons, power buttons, ring/silent buttons, or the like may be positioned on the peripheral side of the watch  5400 , and touch- and/or force-sensing systems may detect inputs applied to those affordances and control the operation of the watch  5400  accordingly. 
     In addition to any touch- and/or force-sensing systems for detecting inputs applied to the glass members of the enclosure, the watch  5400  may include input devices such as a crown  5410  and/or a button  5412 . The crown  5410  may be rotatable relative to the enclosure  5401 , and may also be actuated axially (e.g., pressed towards the enclosure  5401 , like a button). Rotation of the crown  5410  by a user may cause the watch  5400  to modify its operation. For example, the watch  5400  may scroll a user interface in accordance with a rotation of the crown (e.g., in a direction and at a speed that is indicated by the direction and speed of the crown&#39;s rotation). As another example, the rotation of the crown may change a time setting of the watch or a brightness level of a display (or other graphical or operational parameter(s) of the watch  5400 ). The crown  5410  may include a shaft that extends into the enclosure  5401  through an opening in the enclosure  5401 , and the watch  5400  may detect the rotational and optional axial movement of the crown using optical sensors, encoders, Hall effect sensors, resolvers, dome switches, or any other suitable sensing system(s). 
     The button  5412  may be pressed by a user (e.g., axially, towards the enclosure  5401 ) to provide inputs to the watch  5400 . The button  5412  may include a shaft or other component or feature that extends into the enclosure  5401 , through an opening in the enclosure  5401 , to allow button inputs to be detected by the watch  5400  (e.g., by actuating a dome switch or other switch or sensing mechanism). The button  5412  and the crown  5410  may be configured to move relative to the enclosure  5401 , or they may be fixed (e.g., non-moving), and inputs applied to the button  5412  and crown  5410  may be sensed using other techniques (e.g., capacitive sensing). In some cases, the watch  5400  may omit the button  5412  and/or the crown  5410 , and other sensing systems may be used to detect inputs to the watch  5400  (e.g., touch- and/or force-sensing systems associated with the display(s) in the watch  5400 ).  FIGS. 55 and 56  illustrate example watches with enclosures formed substantially entirely from glass and that lack externally-accessible mechanical input devices such as buttons or crowns. 
     The watch  5400  may include various additional components and/or systems, some of which may leverage the optical and radio-transparent properties of the first and second glass members  5402 ,  5404 . For example, the watch may include a wireless (e.g., inductive) charging system that relies on inductive coupling between a receiving coil within the watch  5400  and a power coil external to the watch  5400  (e.g., in a charging dock). The high radio transparency of the glass material of the first and/or second glass members  5402 ,  5404  may facilitate the inductive coupling that enables wireless charging. As another example, the watch may include an optical sensor that leverages the optical transparency of the first and/or second glass members  5402 ,  5404  to facilitate certain sensing functions. More particularly, the watch  5400  may include an optical biometric sensor (e.g., a photoplethysmograph) that relies on the transparency of the second glass member  5404  to certain wavelengths of light to optically detect aspects of the wearer&#39;s skin for sensing heart rate or other biometric information. As yet another example, the radio-transparency of the first and/or second glass members  5402 ,  5404  may facilitate transmitting and receiving radio signals for cellular, WiFi, Bluetooth, or other wireless communications. 
       FIG. 55  illustrates another example wearable electronic device, and specifically a watch  5500  that does not include externally-accessible mechanical input devices such as a crown or button. The watch  5500  includes an enclosure  5501  in which a first major side  5514  (e.g., the face of the watch) and a second major side  5513  (e.g., the wrist-facing side of the watch), and substantially all of the peripheral sides are glass. The watch  5500  may also include a watch band  5508  attached to the enclosure  5501 . The watch band  5508  may be permanently attached to the enclosure  5501 , or it may be removable such that it can be replaced and/or swapped with other bands. 
     The enclosure  5501  may include a first glass member  5502  and a second glass member  5504 . The first glass member  5502  defines the first major side  5514  and a portion of each of the peripheral sides of the enclosure  5501 . The second glass member  5504  defines the second major side  5513  and another portion of each of the peripheral sides. The enclosure  5501  also includes an intermediate member  5506  between the first and second glass members  5502 ,  5504 . The intermediate member  5506  may be metal, plastic, glass, or another suitable material, and may serve as a structural member of the device and may facilitate bonding between the first and second glass members  5502 ,  5504 . Alternatively, the intermediate member may be cosmetic, and may contribute little or no structural strength or rigidity to the enclosure. The first and second glass members  5502 ,  5504  may be secured to the intermediate member  5506  in any suitable way, including mechanical interlocks, adhesives, epoxies, ultrasonic welding, frit bonding, or the like. Many of the enclosure forming techniques and structures described herein with respect to other examples may be used to form enclosure  5501  of  FIG. 55 . Relevant description of such techniques and structures are not repeated in order to reduce redundancy. 
     The watch band  5508  may attach to the enclosure  5501  via the intermediate member  5506 . In cases where the watch band  5508  is not removable, the watch band  5508  may be permanently attached to the intermediate member  5506 . In other cases, such as where the watch band  5508  is removably coupled to the enclosure  5501 , the intermediate member  5506  may include or define part of a channel, lug, or other feature or mechanism with which the watch band  5508  engages to removably couple the watch band  5508  to the enclosure  5501 . 
     As with the other devices described herein, the watch  5500  may include one or more displays that are visible through all or some of the first glass member  5502  and through all or some of the second glass member  5504 , including through the peripheral sides of the enclosure  5501 . Additionally, the watch  5500  may include touch- and/or force-sensing systems that detect inputs applied to the major sides and/or the peripheral sides (or portions thereof) of the watch  5500 . Such touch- and/or force-sensing systems may operate in accordance with capacitive sensing, inductive sensing, optical sensing, or other sensing techniques. 
     Also, similar to other examples provided herein, the graphical output of the display may be modified in accordance with an orientation of the watch  5500 . Additionally, the graphical output and/or other operational characteristics of the watch  5500  may be modified in response to the watch  5500  being worn on a right wrist, a left wrist, resting on a surface, or mounted in a docking station or stand. The watch  5500  may modify the graphical output and/or other operational characteristics of the watch  5500  automatically, based sensor input(s), detected locations, or the like. For example, when a user lifts his or her wrist to view the watch, the watch  5500  may detect the motion and in response output a first type of graphical output (e.g., a watch face viewable through the first major side defined by the first glass member  5502 ). When the user places the watch  5500  on a night stand, desk, or other surface (and optionally on a charger), the watch  5500  may output a second type of graphical output (e.g., the time and an alarm status on a peripheral side of the watch  5500 ). Other types of graphical outputs and triggers (e.g., events, locations, sensed motion, etc.) are also contemplated. For example, the peripheral sides may be illuminated (e.g., with a solid color) to indicate events or provide other notifications (e.g., when a message has been received, when an alarm or timer has expired, or the like). 
     In some embodiments, graphical output from the display may be viewable through one or more additional faces depending on a wearing condition (left or right wrist), an orientation of the device, or placement in a docking station or stand. In some instances, the watch  5500  may be reversible and graphical output may be displayed through either of the major sides in accordance with a wearing condition. 
     As noted above, the watch  5500  does not include externally-accessible mechanical input devices such as a crown or input button. Input functionality similar to that of a mechanical button or crown may be provided by other types of input devices and/or sensors of the watch  5500 . For example, a touch- and/or force-sensing system of the watch  5500  may detect touch- and/or force-based inputs applied to a peripheral side (or a portion thereof) of the watch  5500 . More particularly, an array of electrodes integrated with the enclosure  5501  may define one or more touch- and/or force-sensitive input regions along an exterior surface of the watch  5500  to define one or more virtual or programmable buttons, crowns, slides, or other similar input devices. (The array of electrodes may be part of a touch- and/or force-sensing system that also detects touch and/or force inputs applied to the first and/or second major sides of the enclosure.)  FIG. 55  shows example touch- and/or force-sensitive input regions  5516  along a peripheral side, with which a user may interact to control operations of the watch  5500 . The shapes and positions of the input regions  5516  are merely examples, and may have other shapes or positions in other embodiments. 
     A display within the enclosure  5501  may display affordances that coincide with the input regions  5516  or otherwise indicate that the user can interact with the input regions  5516  to control the watch  5500 . The affordances, and the touch- and/or force-sensing functions, may be activated or deactivated depending on a mode of operation of the watch  5500 . For example, in a first operating mode, the watch  5500  may display a crown-like affordance at one of the input regions  5516 , and respond to inputs applied to the crown-like affordance. In a second operating mode, the crown-like affordance may not be displayed, and the input region  5516  may remain blank or include a different type of affordance or graphical output. For example, in a workout mode, the crown-like affordance may be replaced by a stopwatch start/stop button, an audio control, a lap or split button, or the like. Other modes of operation and associated affordances and/or graphical outputs are also contemplated. 
       FIG. 56  illustrates another example wearable electronic device, and specifically a watch  5600  that includes an enclosure  5601  formed entirely or substantially entirely of glass. Like the other enclosures described herein, the enclosure  5601  may define a first major side  5614  (e.g., the face of the watch), a second major side  5613  (e.g., the wrist-facing side of the watch), and substantially all of the peripheral sides are glass. Whereas the enclosures  5401  and  5501  included an intermediate member that may be formed of a non-glass material such as a polymer or a metal, the enclosure  5601  may lack non-glass elements that define exterior surfaces of the enclosure  5601  (or at least may lack the intermediate member). The enclosure  5601  may be formed using the techniques described above with respect to other types of electronic devices (including but not limited to those shown and described with respect to  FIGS. 5A-9B, 10A-15, 18-25D ). For example, multiple glass elements may be attached together using adhesives, glass frit bonding, or the like. As another example, a single glass structure may be molded or otherwise formed around the device components. As yet another example, an opening may be formed in an otherwise fully enclosed monolithic glass member, and components may be introduced into the glass structure through the opening (which may then be sealed, capped, or otherwise closed off, as described with respect to  FIG. 40  for example). Further description of these and other techniques and structures are not repeated in order to reduce redundancy. 
     The enclosure  5601  may also define attachment features  5606  to which a watch band may be attached. The attachment features  5606  may be formed of glass, and may be part of a monolithic or unitary glass structure that defines the enclosure  5601  (or, in the case of a non-monolithic enclosure or enclosure member, they may be integral with one of multiple glass members that together define the enclosure  5601 ). In other examples, the attachment features  5606  may be formed separately from the enclosure  5601  and attached to the enclosure  5601 . For example, the attachment features  5606  may be formed of a metal, polymer, or other suitable material, and adhered or otherwise affixed to the enclosure  5601 . A watch band  5608  may be attached to the attachment features  5606 , for example, by being looped around the attachment features  5606 . The band  5608  may attach to the enclosure  5601  using other types of attachment features. For example, instead of the lug-like attachment features  5606  in  FIG. 56 , the watch  5600  may include slots or channels that may receive and engage the band  5608 . In another example, a band  5608  may be affixed directly to the exterior glass surface of the enclosure  5601  using adhesives or any other suitable technique. 
     As with the other devices described herein, the watch  5600  may include one or more displays that are visible through all or some of the surfaces of the enclosure  5601 . Additionally, the watch  5600  may include touch- and/or force-sensing systems that detect inputs applied to the major sides and/or the peripheral sides (or portions thereof) of the watch  5600 . Such touch- and/or force-sensing systems may operate in accordance with capacitive sensing, inductive sensing, optical sensing, or other sensing techniques. 
     Also, similar to other examples provided herein, the graphical output of the display may be modified in accordance with an orientation of the watch  5600 . Additionally, the graphical output and/or other operational characteristics of the watch  5600  may be modified in response to the watch  5600  being worn on a right wrist, a left wrist, resting on a surface, or mounted in a docking station or stand. The watch  5600  may modify the graphical output and/or other operational characteristics of the watch  5600  automatically, based sensor input(s), detected locations, or the like. For example, when a user lifts his or her wrist to view the watch, the watch  5600  may detect the motion and in response output a first type of graphical output (e.g., a watch face viewable through the first major side). When the user places the watch  5600  on a night stand, desk, or other surface (and optionally on a charger), the watch  5600  may output a second type of graphical output (e.g., the time and an alarm status on a peripheral side of the watch  5600 ). Other types of graphical outputs and triggers (e.g., events, locations, sensed motion, etc.) are also contemplated. For example, the peripheral sides may be illuminated (e.g., with a solid color) to indicate events or provide other notifications (e.g., when a message has been received, when an alarm or timer has expired, or the like). 
     In some embodiments, graphical output from the display may be viewable through one or more additional faces depending on a wearing condition (left or right wrist), an orientation of the device, or placement in a docking station or stand. In some instances, the watch  5600  may be reversible and graphical output may be displayed through either of the major sides in accordance with a wearing condition. 
     Similar to the watch  5500 , the watch  5600  does not include externally-accessible mechanical input devices such as a crown or input button. Input functionality similar to that of a mechanical button or crown may be provided by other types of input devices and/or sensors of the watch  5600 , as described above with respect to  FIG. 55 . Relevant description of such techniques and features are not repeated in order to reduce redundancy. 
       FIG. 57  illustrates another example wearable electronic device, and specifically a watch  5700  that includes an enclosure  5701  formed entirely or substantially entirely of glass. The watch  5700  may be substantially similar to the watch  5600 , except that the watch  5700  includes input devices such as a crown  5710  and/or a button  5712 . Like the crown and button of the watch  5400 , the crown  5710  may be rotatable relative to the enclosure  5701 , and may also be actuated axially (e.g., pressed towards the enclosure  5701 , like a button). Rotation of the crown  5710  by a user may cause the watch  5700  to modify its operation, as described above. The watch  5700  may detect the rotational and optional axial movement of the crown using optical sensors, encoders, Hall effect sensors, resolvers, dome switches, or any other suitable sensing system(s). The button  5712  may be pressed by a user (e.g., axially, towards the enclosure  5701 ) to provide inputs to the watch  5700 . 
     Like the other enclosures described herein, the enclosure  5701  may define a first major side  5714  (e.g., the face of the watch), a second major side  5713  (e.g., the wrist-facing side of the watch), and substantially all of the peripheral sides are glass. The enclosure  5701  may also define attachment features  5706  to which a watch band may be attached. The attachment features  5706  may be similar to the attachment features  5606 , described above. 
     The enclosure  5701  may be formed using the techniques described above with respect to other types of electronic devices (including but not limited to those shown and described with respect to  FIGS. 5A-9B, 10A-15, 18-25D ). For example, multiple glass elements may be attached together using adhesives, glass frit bonding, or the like. As another example, a single glass structure may be molded or otherwise formed around the device components. As yet another example, an opening may be formed in an otherwise fully enclosed monolithic glass structure, and components may be introduced into the glass structure through the opening (which may then be sealed, capped, or otherwise closed off, as described with respect to  FIG. 40  for example). Further description of these and other techniques and structures are not repeated in order to reduce redundancy. 
     The crown  5710  may include a shaft that extends into the enclosure  5701  through an opening in the enclosure  5701 . The button  5712  may include a shaft or other component or feature that extends into the enclosure  5701  through an opening in the enclosure  5701 . In some cases, the openings through which portions of the crown  5710  and/or the button  5712  extend are used to insert components of the watch  5700  into the enclosure  5701 . For example, components may be inserted into the enclosure  5701  through the crown and/or button openings using a technique similar to that described with respect to  FIG. 40 . In particular, components such as displays, batteries, processors, circuit boards, memory, sensors, support structures, and the like may be inserted into an internal volume of the enclosure  5701  through one of the openings. The components may be arranged inside the enclosure  5701  (optionally including unfolding or otherwise expanding or re-configuring components), and the openings may be closed by the crown and/or button. The openings for the crown and/or button may be formed after forming a completely enclosed glass enclosure. For example, the openings may be drilled, machined, or otherwise formed into the glass to provide access to the interior volume of the enclosure  5701 . In some cases, the openings for the crown and/or button are the only openings in an otherwise continuous, monolithic glass enclosure  5701 . 
     While the crown  5710  and the button  5712  are shown having an example size and shape, other sizes and shapes are also possible. Further, either the crown or button may be omitted, or other input devices may be included in addition to the crown and button. For example, the watch  5700  may include a single button that extends substantially the entire length of the peripheral side (e.g., 70% or greater of the length of the peripheral side). This may allow the opening to have a greater size than would be afforded if the watch used smaller buttons or crowns, and may help facilitate the manufacturability of the device. 
     In some cases, a single opening may be formed to facilitate assembly of the internal components of a watch, and a partial cap may be added to cover at least part of the opening while leaving one or more openings for the input devices.  FIG. 58  shows a partial side view of an example enclosure  5800 , which may be an embodiment of the enclosure  5701  and which may use a partial cap to cover an opening in one of the walls of the enclosure  5701 . The enclosure  5800  includes an opening  5801  in a peripheral side of the enclosure  5800 . After components of the watch are inserted into the enclosure  5800  through the opening  5801 , a partial cap  5806  may be attached to the enclosure  5800  to partially occlude the opening  5801 . The cap  5806  may partially define one or more openings in the enclosure  5800 , such as the opening  5802  and  5804 . Components of a crown, button, or other input device (or any other suitable component) may extend into the interior volume of the enclosure  5800  through the openings  5802 ,  5804 . The number, shape, and position of the openings  5802 ,  5804  are merely examples, and other configurations are also contemplated. 
     The partial cap  5806  may be formed from any suitable material. In some cases, the partial cap  5806  is formed of glass and is attached to the main body of the enclosure  5800  using an adhesive, glass frit bonding, fusion bonding, or any other suitable attachment technique. In other cases the partial cap  5806  may be formed form a polymer, crystal, metal, or the like. 
     The foregoing descriptions of the watches  5400 ,  5500 ,  5600 ,  5700 , and  5800  illustrate some specific features that may be present in watches that include enclosures formed entirely or substantially entirely of glass. Other variations and embodiments are also contemplated. For example, any and all other features described herein with reference to other types of devices, including but not limited to other embodiments of enclosures, displays, user interfaces, operational modes, as well as materials and manufacturing and/or assembly techniques, may be applied to the watches  5400 ,  5500 ,  5600 ,  5700 , and  5800  as well. Further, components, functions, structures, or other descriptions of any given watch described herein may apply equally or by analogy to other watches described herein. 
     The foregoing description describes concepts with reference to various example embodiments, and it will be understood that concepts described with respect to one particular embodiment, form factor, implementation, or device is applicable to other embodiments, form factors, implementations, or devices as well. For example, components, assemblies, construction techniques, assembly techniques, user interfaces, or any other concepts that are described with respect to a device having a shape of a rectangular prism apply equally and/or by analogy to devices having other shapes (e.g., cylinders, triangular prisms, octagonal prisms, hexagonal prisms, or the like). Further, the foregoing description, for purposes of explanation, used specific nomenclature to provide a thorough understanding of the described embodiments. However, it will be apparent to one skilled in the art that the specific details are not required in order to practice the described embodiments. Thus, the foregoing descriptions of the specific embodiments described herein are presented for purposes of illustration and description. They are not targeted to be exhaustive or to limit the embodiments to the precise forms disclosed. It will be apparent to one of ordinary skill in the art that many modifications and variations are possible in view of the above teachings. Also, when used herein to refer to positions of components, the terms above and below, or their synonyms, do not necessarily refer to an absolute position relative to an external reference, but instead refer to the relative position of components with reference to the figures.
