Description:
FIELD 
     The described embodiments relate generally to components for an electronic device. More particularly, the present embodiments relate to components and structures for electronic devices including displays. 
     BACKGROUND 
     The components of an electronic device, for example, a housing of an electronic device and associated components, can include structures having features tailored to the specific purposes for which they are employed. The components can be configured to provide physical support or protection to other components of the electronic device, provide for thermal transmission, provide for airflow through or around the electronic device, or provide for any number of additional purposes. The components of the electronic device can be designed to provide a unique and pleasing look and feel for a user. Additionally, the components can be designed to optimize one or more dimensions of the device, such as an amount of an active area of the device. 
     Recent advances in electronic devices have enabled high levels of performance. Existing components, structures, and methods of assembly for electronic devices, however, can limit the levels of performance of such devices. For example, traditional housings can limit the amount or relative percentage of active area of a display. Similarly, traditional methods of device assembly can include features or components that inhibit device performance, even when non-traditional housing structures are used. Further, traditional structures and methods used to assemble an electronic device can undesirably limit one or more dimensions of the device relative to the individual dimensions of each component. In this regard, further tailoring of components for electronic devices can provide additional or enhanced functionality, desired dimensions, and pleasing aesthetic features.

     DETAILED DESCRIPTION 
     Reference will now be made in detail to representative embodiments illustrated in the accompanying drawings. It should be understood that the following descriptions are 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 architecture and components of electronic devices, including display portions, described herein, can allow for configurations of an electronic device that can maximize the active area of a display or display cell in a display portion, while still achieving desired levels of functionality. In traditional electronic device configurations, such as with traditionally designed desktops, the display device can include relatively large bezels or borders around most or all of the periphery of the active display cell to hide components for mounting the display cell or display assembly in the display portion housing, for example, components that can fix the directional movement and/or position of the display cell in one or more directions relative to the display housing. 
     The components, features, and configurations described herein can allow for display device designs that maximize the user-facing active area of the display, while minimizing or even eliminating the bezels adjacent to the display cell, while maintaining the same or even improving levels of display performance. For example, the display portions described herein can have relatively small or even no bezel area around the edges or sides of a display cell, with a relatively small bezel or chin disposed along a bottom edge of the display cell. Such a reduced border configuration can utilize additional unique designs to accommodate for the improved display area. In some examples, internal mounting features are provided to fix the position and limit or fix the directional movement of the display assembly relative to the display housing in one or more directions or degrees of freedom. In some examples, the display portion can include one or more user-facing components, such as a camera indicator light or other illumination component, that can be positioned at an edge of the display, but that may not require a bezel or inactive region that extends across an entire dimension of the display. 
     One aspect of the present disclosure relates to an electronic device including a housing that defines an exterior surface and an internal volume of the electronic device. The electronic device can include display components positioned partially or entirely within the internal volume. The display components can include a backlight unit positioned in the internal volume and a cover assembly that can include a cover defining an exterior surface of the device. The device can include one or more sealing/attachment features that couple the cover assembly to the backlight unit. The cover assembly can also include a display unit. The backlight unit can define or include one or more retention features that can engage with one or more corresponding engagement features affixed to the housing in the internal volume. A securing component, such as a shaft and a shim, can be disposed between the installed backlight unit and the housing to prevent the backlight unit from moving relative to the housing. 
     The cover assembly can overlay or overlap the backlight unit. The cover defining the exterior surface, which can be a transparent cover such as glass, sapphire, or plastic, can be attached to the backlight unit, which in turn is fastened or secured to the housing. The cover can further be sealed to the housing along the periphery of the housing by a reworkable pressure sensitive adhesive inserted into a thin gap between the edges of the housing and the cover. 
     A frame, such as ring including a polymer or polymer-ceramic composite material like glass-filled polycarbonate, can be positioned between the cover and the backlight unit. The frame can extend along a periphery of the cover and/or the backlight unit. In some examples, the frame is a single continuous piece. The frame can be secured to the cover using an adhesive, such as a reworkable pressure sensitive adhesive. In some examples, the frame can at least partially define an aperture sized to allow one or more components to pass there through. In some examples, the frame and a component of the backlight unit are coupled to the frame and define the aperture. In some examples, the aperture can be defined by an angled surface to accommodate an electrical component, such as a flexible electrical connector or flexible printed circuit that extends from the cover assembly to the backlight unit or to other components of the display. The angled surface of the frame can be shaped to conform to a minimum radius that the flexible circuit can bend before becoming damaged. In some examples, a portion of the frame is in direct contact with the cover. The frame can be secured to the cover with an adhesive, the frame defining a notch to receive the adhesive. In some examples, the notch operates as a datum for adhesive. The adhesive can include a reworkable pressure sensitive adhesive. 
     In some examples, the frame is also attached to the backlight unit with an adhesive. In some examples, the frame is attached to the backlight unit using attachment features, such as screws, snaps, magnets, or latches. The frame can include retention features, such as threaded metal inserts to receive fasteners to secure the backlight unit to the frame. In some examples, the fasteners are threaded directly into the material of the frame. The frame can help to improve the seal between the cover assembly and the backlight unit, for example by preventing the ingress of dust particles or other material that can adversely affect the quality of an image produced by the display. 
     In some examples, the components and systems described herein can allow for display devices to include narrow bezels or borders surrounding an active area of a display assembly, such as a liquid crystal display (LCD) assembly. These narrow borders do not traditionally provide sufficient material for hardware to engage and retain the components of the device, such as the backlight or cover assembly without the insertion of screws through the rear major surface of the housing or through a sidewall of the housing. The systems and components described herein can facilitate front mounting and secure retention of the display components, while maintaining narrow bezels and borders without the need for additional fasteners. 
     In some examples, the mounting systems described herein can enable the components of an electronic device, such as display components, circuit boards, fans, and other electronic components, to be disposed adjacent to, or in close proximity to, a major surface of a housing having a structure as described herein. This arrangement of components can aid in maximizing the thermal benefits provided by the housing structure. 
     Unlike traditional methods of retaining components in an electronic device without passing hardware through major surfaces of the housing, such as gluing components directly to the housing, the present mounting system allows for disassembly of the device without causing undesirable damage to the housing and/or components. Accordingly, electronic devices assembled with the present mounting systems allow for devices to be disassembled, for example, to repair or replace individual components or to recycle or reuse individual components. 
     In some examples, a display assembly (including the cover assembly and the backlight unit) can be at least partially disposed in the internal volume defined by the housing. The display assembly can, in part, be secured to the enclosure using a reworkable adhesive. Mounting features can be included to ensure proper coupling of the display assembly and the housing. In some examples, one or more support components can be attached to the housing. The support components can engage with one or more retention components that can be attached to a backlight unit of the display. In some examples, the mounting features include support components that are spaced equidistance from a center of the housing and corresponding retention components positioned equidistance from a center of the display unit. 
     As described, the present systems allow for a display device including narrow bezels surrounding the active area of a display assembly, such as a liquid crystal display (LCD) assembly. These narrow borders do not traditionally provide sufficient space for a notification light or other illumination components, for example, as associated with a camera module. In some examples, the display devices described herein can include a camera and a camera use indicator light. In some examples, to allow for a reduced internal volume of the device, the system includes indicator lights which allow for an LED package to be positioned orthogonal to an output surface of the indicator light. 
     In some examples, an LED package of the indicator light is positioned above a light pipe or a light guide. The LED package can be oriented such that light is initially emitted parallel to a major surface of the cover, such as a right angle. The light can then enter a light pipe including a reflective angled surface that can reflect the light, such that the light is ultimately emitted in a direction perpendicular to the major surface of the cover glass (i.e., toward the user). A reflective coating can be applied to the angled surface of the light pipe to provide efficient transmission of the light with as little diffusion or loss as possible. In some examples, the LED package emits green light, and the reflective coating includes a plurality of ceramic layers such as titanium dioxide layers and silicon dioxide layers. In some examples, the reflective coating can include between 5 and 50 alternating titanium dioxide and silicon dioxide layers, for example, about 25 alternating titanium dioxide layers and silicon dioxide layers. The reflective coating can have a thickness of between about 1000 nm and about 3000 nm, for example, about 2000 nm or about 2078 nm. 
     Generally, the devices described herein are used in an upright position. As used herein, an “upright” configuration or position is a configuration in which an elongated height dimension of the device is more parallel than perpendicular relative to the gravitational direction. For example, an electronic device is upright when it is in a vertical orientation similar to a picture frame hanging on a wall or supported by a kickstand. With this understanding, the terms “top,” “bottom,” “side,” “front,” “back,” “rear,” “above,” “below,” “under” and other such positional terms are to be understood in relation to an upright electronic device, but are used for reference purposed only. For example, a top portion of a device can be located above a bottom portion in some orientations of the device, but can also be located in line with, below, or in other spatial relationships with the bottom portion depending on the orientation of the device. These reference terms are not intended to limit the device to any one orientation and it should be understood that the devices described herein can be used or operated in orientations other than upright. Additionally, the term “length” or “height” refers to a top-to-bottom measurement, the term “width” refers to a side-to-side measurement, and the term “thickness” refers to a front to back measurement. 
     These and other embodiments are discussed below with reference to  FIGS. 1-11 . However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these Figures is for explanatory purposes only and should not be construed as limiting. 
       FIG. 1  illustrates a perspective view of an electronic device  100 . The electronic device  100  shown in  FIG. 1  is a display or a monitor, for example, as can be used with a personal or desktop computer. This is, however, merely one representative example of a device that can be used in conjunction with the ideas disclosed herein. The electronic device  100  can, for example, correspond to a portable media player, a media storage device, a portable digital assistant (“PDA”), a tablet computer, a computer, a mobile communication device, a GPS unit, a remote-control device, or other electronic devices. The electronic device  100  can be referred to as an electronic device, a device, or a consumer device. As shown, the electronic device  100  can include any number of input devices such as a mouse  109 , a keyboard  110 , a track pad, a stylus, a microphone, or any combination of input devices. The electronic device  100  can include a display  108 , a housing  101 , a chin  104 , and a stand  106 . The display  108  can include a computer display such as, for example, a liquid crystal display (LCD), organic light-emitting diode (OLED) display, or any desired display component. The display  108  can be referred to as a monitor, a display screen, or a display assembly of the electronic device  100 . The housing  101  can be a shell to protect and cover parts of the display  108 . In some examples, the housing  101  can include any desired materials, such as rigid and durable materials. For example, the housing  101  can include plastic, metal, ceramic, glass materials, or combinations thereof. In some examples, the housing  101  can include aluminum. In some examples, the housing  101  can define a bezel (i.e., a front-facing surface of the housing) extending around a perimeter of the display  108 . In some examples, the housing  101  defines no bezel or chin  104  (i.e., the electronic device includes a full glass front). Further details of the electronic device  100  are provided below with reference to  FIG. 2 . 
       FIG. 2  illustrates a front view of the electronic device  100 . As shown in  FIG. 2 , the display  108  of the electronic device  100  can extend to the outer edge perimeter of the housing  101 . The housing  101  can define an aperture, or can be an open-ended enclosure wherein the display  108  is positioned within the aperture to define an internal volume within the housing  101 . The chin  104 , can also be affixed to the housing  101  to define, at least in part, the internal volume. In some examples, the chin  104  can be integrally formed with the housing  101 . The chin  104  can be adjacent to, and can be flush with, an exterior surface defined by the display  108 . The chin  104  can contain internal electrical components. In some examples, the display  108  may not extend beyond or overlap with the chin  104 , which can provide additional space in the internal volume of the device  100  when the chin  104  is thinner than the display  108 . Thus, the internal volume defined between the chin  104  and the housing  101  can be used for larger internal components that may not otherwise fit between a rear surface of the display  108  and the housing  101 . In some examples, the thickness of the housing  101  and the display  108  can be approximately equal to the thickness of the chin  104  and the housing  101  when the electronic device  100  is assembled. Accordingly, in some examples, the device  100  can have a substantially constant thickness along one or both of its width and height. In some examples, the display  108  is at least partially supported by the chin  104 . In some examples, the display  108  extends fully to the bottom edge of the housing  101  (i.e., there is no chin  104 ). Further details of the electronic device  100  are provided below with reference to  FIG. 3 . 
       FIG. 3  illustrates a perspective exploded view of the electronic device  100 . The electronic device  100  can include a housing  101  at least partially defining an exterior surface and an internal volume of the device. In some examples, the housing can include a portion or region that can define a first surface and a second surface. In some examples, the display assembly  108  includes a cover assembly  111  and a backlight unit  113 . The backlight unit  113  can be positioned between a major surface of the housing  101  and the cover assembly  111 . 
     Although illustrated as a backlight unit  113 , the electronic device  100  can include substantially any desired display or device component. The backlight unit  113  can include a backplate  128  that can be disposed adjacent to a major surface of the housing  101  at least partially defining the internal volume. In some examples, the backplate  128  can assist in conducting heat generated by components of the device  100  to the housing  101 , where the housing structure can further aid in removing the heat from the device  100 , for example, via convection. Thus, the backplate  128  can include a relatively thermally conductive material, such as a metal, for example, alloys of steel, aluminum, copper, and other metals. In some other examples, however, the backplate  128  can include metal, ceramic, polymer, or combinations thereof. In some examples, engagement features (not shown) can secure the backplate  128  to the housing  101  and can further seal the backplate  128  and the housing  101 , for example, through apertures in the backplate  128 . Although referred to separately as a housing  101  and a backplate  128 , in some examples, the housing  101  and the backplate  128  are referred to together as a housing. 
     In some examples, the backlight unit  113  can include internal components, such as one or more light emitting diodes (LEDs), cavity reflectors associated with the LEDs, internal posts that can define a thickness of the backlight unit  113 , and printed circuit boards, as described herein. A portion of the backlight unit  113 , such as a rear major surface thereof, can define one or more retention features that correspond to and can engage with the engagement features protruding from the backplate  128 . 
     The backlight unit  113  can be relatively heavy compared to other components of the device  100 , so multiple securing and retention features can be used to secure the backlight unit  113  to both the cover assembly  111  and the housing  101  to evenly support the weight of the cover assembly  111  and/or the backlight unit  113  over a large area of the housing  101 . Further, the design of the housing  101 , the backplate  128 , and the retention features can allow for intimate thermal contact between components of the backlight unit  113  and the backplate  128 , thereby providing for increased thermal conduction and improved device cooling. During assembly, the backlight unit  113  can be inserted into the internal volume so that support components or features attached to the housing  101  can pass into the retention features to provide mechanical support to the backlight unit  113  and to fix the backlight unit  113  relative to the housing  101  along one or more axes. As the backlight unit  113  can be securely connected to the housing  101  via the retention features, the number of additional features or securing components disposed around a periphery of the backlight unit  113  can be reduced, thereby allowing the backlight unit  113  to extend substantially an entire height and/or width of the internal volume, and providing a desired level of lighting to any display unit positioned thereover. 
     The cover assembly  111  can include a transparent cover  112 , which can at least partially define an exterior surface of the device  100 . Together, the housing  101  and the cover  112  can substantially define the exterior surface and/or the internal volume of the device  100 . The cover  112  can include any desired transparent material, for example, glass, plastic, sapphire, other transparent materials, or combinations thereof. In some examples, a display unit  114  can be adhered to the cover  112 , for example, to a surface of the cover  112  opposite the portion defining the exterior surface of the device  100 . In some examples, the display unit  114  can be an LCD unit, although in other examples any form of display unit  114  can be used as desired, such as an LED display unit, OLED display unit, plasma display unit, quantum dot display unit, other display units, or combinations thereof. The display unit  114  can be affixed to the cover by gluing, adhering, or any other desired securing technique. Further, in some examples, the cover  112  can cover additional components such as a camera, or a touch sensitive surface such as a touchscreen. In some examples, the display unit  114  can include one or more electronic components, such as printed circuit boards including processors, memory, and other electrical components. 
     The cover  112  can be fastened to the backlight unit  113 , for example, through a frame  116  disposed along a periphery of the cover  112  and/or backlight unit  113 , as described further herein. Any number of additional internal components can be disposed between the housing  101  and the cover  112 . For instance, the device  100  can also include internal components such as processors, memory, circuit boards, batteries, fans, sensors, and other electronic components. Such components can be disposed within the internal volume defined at least partially by the housing  101  and the cover  112 , and can be affixed to the housing  101  via internal surfaces, attachment features, threaded connectors, studs, or posts that are formed into, defined by, or otherwise part of the housing  101  and/or the cover assembly  111 . Additional features of the electronic device  100  are provided below with reference to  FIG. 4 . 
       FIG. 4  shows a front view of the electronic device  100  in a partially assembled state with the cover  112  removed. As shown, the frame  116  can extend around a periphery of the cover assembly  111  and/or of the backlight unit  113 . In some examples, the frame  116  can have a peripheral shape corresponding to a peripheral shape of the cover assembly  111 , the backlight unit  113 , and/or the housing  101 . In some examples, the frame  116  can extend around substantially an entire periphery of the cover  112 , the backlight unit  113 , and/or the housing  101 . In some examples, the frame  116  can be positioned between an edge or a side of the display unit  114  and an edge or side of the housing  101 . In some examples, the frame  116  can include multiple members, portions, or pieces that can be joined or formed together to form the frame  116 . In some examples, the frame  116  can include a single continuous piece or portion, for example, having a ring shape. In some examples where the frame  116  is a single continuous piece, portions or regions of the frame  116  can still be referred to as members or sidewalls. In some examples, such as where the frame  116  has a ring shape, the frame  116  can define a main aperture or opening. In some examples, the frame  116  can include a metal, a polymer, a ceramic, or combinations thereof. In some examples, the frame  116  can include a polymer such as polycarbonate. In some examples, the frame  116  can include a polymer-ceramic or polymer-metal composite material, such as a glass-filled polymer material. In some examples, the frame  116  can include a glass-filled polycarbonate material. Further details and features of the electronic device  101  are provided below with reference to  FIG. 5 . 
       FIG. 5  illustrates a cross-sectional side view of a portion of the electronic device  100  taken along the line  5 - 5  shown in  FIG. 2 . In some examples, the cover assembly  111  and the backlight unit  113  are joined, coupled, or otherwise secured together by the frame  116 . The frame  116  can be a plastic frame with a periphery that extends around the backlight unit  113 . In some examples, the frame  116  includes glass-filled polycarbonate. The frame  116  can be a single unitary piece and can improve a dust seal of the device  100 . The frame  116  can be directly or indirectly attach to the cover  112  using adhesive  140 . The adhesive  140  can be moldable and can be, for example, a hot melt glue. In some examples, a portion of the frame  116  is in direct contact with the cover  112 . In some examples, the frame  116  defines a notch, step, or cavity  141  adjacent the cover  112 . The notch  141  can receive the adhesive  140  to secure the frame  116  to the cover  112 . The notch  141  can also serve as a datum to fix the position of the frame  116  relative to the cover  112  in one or more dimensions. In some examples, this datum configuration can allow for a desired amount of adhesive  140  to be applied between the frame  116  and the cover  112  (i.e., to ensure enough of the adhesive  140  is applied to provide proper coupling and also to prevent too much adhesive  140  from being applied that could occupy undesirable locations within the device  100 ). The notch  141  can be between about 0.1 mm wide and about 5 mm wide, or between about 0.5 mm wide and about 2 mm wide, for example about 1 mm wide. In some examples, the notch  141  can be between about 0.1 mm thick and about 2 mm thick, or between about 0.2 mm thick and about 1 mm thick, for example about 0.4 mm thick. There can be multiple notches  141  in the frame  116 , for example, corresponding to multiple adhesive locations. In some examples, the notch  141  extends an entire periphery of the frame  116 . In some examples, the adhesive  140  can be in the form of a bead of adhesive material and can be positioned substantially entirely around a perimeter of the frame  116  prior to its affixation to the cover  112 . The adhesive  140  can serve to further reinforce or define a seal at those locations to which it is provided, for example, to enable an air or water tight seal, and/or a dust-proof or dust-resistant seal while still allowing for a desired level of ease of removal of components from the device, such as the cover  112 . 
     In some examples, the frame  116  can at least partially define one or more component apertures to allow a component, such as a flexible component, including a flexible printed circuit or flexible electrical connector  136  to pass from the cover assembly  111  and/or the backlight unit  113  through an aperture and to one or more components in the internal volume of the device  100 . As described herein, the frame  116  can be attached or secured to a mounting component  121  of the backlight unit  113 . Accordingly, in some examples, the mounting component  121  can also at least partially define one or more component apertures to allow a component, such as a flexible component, including a flexible printed circuit or flexible electrical connector  136  to pass from the cover assembly  111  and/or the backlight unit  113  through an aperture and to one or more components in the internal volume of the device  100 . In some examples, the frame  116  and the mounting component  121  can define one or more apertures. 
     In some examples, a portion of the frame  116 , such as the portion defining the one or more component apertures, can define an angled or curved surface to allow a component, such as a flexible component, including a flexible printed circuit or flexible electrical connector  136  to pass from the cover assembly  111  and the backlight unit  113  and to further allow for reduced borders of the electronic device  100 . The flexible component  136  can have a minimum bend radius that it can deform or bend to. Thus, in order to allow for a more gradual bend in the flexible circuit  136  while still reducing the borders of the device, the frame  116  can define an angled or curved surface to allow the flexible circuit  136  to begin bending before clearing the frame  116 . Likewise, a portion of the mounting component  121  defining one or more component apertures can be shaped to define a surface with a corresponding angle that coincides with the angle of the frame  116 . In some examples, the surface defined by the frame  116  can be angled at about 45 degrees. It will be noted, in other locations, the frame  116  can have a substantially flat or planar geometry. That is, the frame  116  can be angled at locations where a flexible component  136  is passing (i.e., the remainder of the frame  116  can be flat on its sides). In some examples, the electronic device  100  includes a touch sensitive layer (not shown) which can at least partially pass between the one or more apertures defined by the frame  116  and/or the mounting component  121  of the backlight assembly  113 . 
     In some examples, the cover  112  is secured to the housing  101  using adhesive  132 . In some examples, the adhesive  132  and/or any of the other adhesives described herein, such as adhesive  140  described above, can include a reworkable adhesive. In some examples, this adhesive  132  can be a reworkable pressure sensitive adhesive, such as a reactive hot melt pressure sensitive adhesive. Further, the adhesive  132  can be applied as a single component material in a warm or heated state, whereupon it can subsequently cool and/or react with ambient moisture to fix the cover  112  to the housing  101 . In some examples, the adhesive  132  can include a polymer or polymers capable of one or more forms of cross-linking, and in a cooled state can include a cross-linked urethane polymer network. In some examples, the adhesive  132  can include polyurethane. The adhesive  132  can adhere to the materials of the cover  112  and the housing  101 , including metals such as aluminum or stainless steel, ceramics such as glass, and plastics. In some examples, the adhesive  132  can be in the form of a bead of adhesive material, and can be positioned substantially entirely around a perimeter of the cover  112  and/or the housing  101 . 
     In some examples, the adhesive  140  can be substantially similar to adhesive  132 , for examples, both adhesives  132 ,  140  can be reworkable. In some examples, the reworkable nature of the adhesives  132 ,  140  allows the adhesives  132 ,  140  to be reheated and removed as a substantially unitary component from the device  100  if disassembly of the device  100  is desired. For example, to facilitate cleaning, repair, or recycling of one or more components of the device  100 , one or more of the adhesives  132 ,  140  can be removed to access the internal components of the device  100 . Accordingly, in some examples, the temperature range to release the reworkable adhesives  132 ,  140  can be greater than a temperature of the adhesive location during regular operation of the device  100 , but less than a temperature that would damage the components adjacent to the adhesives  132 ,  140 . In some examples, the adhesives  132 ,  140  can be substantially chemically or environmentally inert, can be opaque or non-transparent, and can have a color, such as matte black. Further details of the electronic device  100  are described below with reference to  FIG. 6 . 
       FIG. 6  illustrates a cross-sectional side view of a portion of the electronic device  100 . With reference to  FIG. 2 , the view depicted in  FIG. 6  can represent a lower or bottom region of the electronic device  100 , although in some examples the components described with respect to  FIG. 6  can be located at any position in the device  100 . As discussed above, with reference to  FIG. 5 , the cover assembly  111  and the backlight unit  113  can be attached by the frame  116 . Specifically, the frame  116  can be glued to the cover  112  with adhesive  140  (not shown in  FIG. 6 ). Further, the frame  116  can be attached to the backlight unit  113  using attachment components  144 , such as fasteners, magnets, latches, snaps, etc. In some examples, the attachment components  144  are threaded screws that are inserted through an aperture in the backplate  128  and are then removably threaded into one or more retention features defined by the frame  116 . In some examples, the frame  116  is attached to the backplate  128  with a plurality of attachment features or components  144 . For example, there can be four attachment components  144 , each corresponding to a side or a corner of the device  100 . In some examples, the frame  116  is insert molded around retention components, such as threaded metal inserts configured to receive the fasteners  144 . In some examples, the frame  116  is secured to the backlight unit  113  with adhesive, such as the reworkable adhesives discussed herein. It will be understood that with the frame  116  glued to the cover  112 , and the frame  116  further fastened to the backlight unit  113 , the cover assembly  111  and the backlight unit  113  are coupled to each other. 
     In some examples, the backlight unit  113  includes a light bar  148 , such as an LED bar, to emit light into a light guide plate  156 . In some examples, the light bar  148  includes an aluminum printed circuit board. In some examples, the light bar  148  can be welded to the backplate  128 . For instance, the aluminum of the light bar  148  can be laser welded to the aluminum of the backplate  128 . By welding the light bar  148  to the backplate  128 , the light bar  148  is able to better dissipate heat because the weld creates an efficient thermal induction pathway into the backplate  128 . Thus, in some examples, there is no need for air flow over the light bar  148 . Further, in some examples, there can be a plurality of light bars welded to the backplate  128 . By welding the light bars to the backplate  128  instead of using fasteners or other traditional attachment techniques, the number of light bars can be increased without increasing the need for additional cooling of the backlight unit  113 . 
     By implementing one or more of the above configurations, the border of the device  100  can advantageously be reduced. In some examples, the border can be removed entirely and the entire front of the device  100  can consist of the cover  112 . Any number or variety of components in any of the configurations described herein can be included in the electronic device. The components can include any combination of the features described herein and can be arranged in any of the various configurations described herein. The structure and arrangement of components of an electronic device having a housing with structures described herein, and defining an internal volume, as well as the concepts regarding engagement and retention features, can apply not only to the specific examples discussed herein, but to any number of embodiments in any combination. Various embodiments of electronic devices including components having various features in various arrangements are described below, with reference to  FIGS. 7A-9 . 
       FIG. 7A  illustrates a cross-sectional rear view of select components of an electronic device  200 . The electronic device  200  can be substantially similar to, and can include some or all of the features of the electronic device  100  described herein, such as a backplate  228 . As discussed above, in some examples, the display  208  can be attached to the enclosure or housing  101  using reworkable PSA. To reduce a load that must be carried by the adhesive and reliably fix the position of the display  208  with respect to the enclosure of the device  200  along one or more axes, the electronic device  200  can include one or more retention components, such hangers, receivers, or retention components  203  that provide a hard stop for the display  208 . The retention components  203  can be fixed to a rear major surface of the display  208 , such as the backplate  228 . Such a hard stop can be particularly useful when the electronic device includes a full cover front (i.e., no chin or lower housing portion for the cover to rest on). 
       FIG. 7B  illustrates a perspective view of one of the retention components  203 . The retention components  203  can aid in securing the backlight unit  213  to the housing  201  in a desired location. In some examples, the retention components  203  can be glued (e.g., by epoxy  217  in  FIG. 9 ) or otherwise affixed to a rear side of the backplate  128  (i.e., opposite the cover assembly  211 ). In some examples, the retention components  203  can include metal, such as stainless steel. In some examples, the retention components  203  can include a sheet of material, such as a sheet of metal, plastic, ceramic, or combinations thereof. In some examples, the retention components  203  can include a sheet of steel or aluminum. 
     The retention component  203  can define a gap, a slot, or an aperture  205 . In some examples, the retention component  203  can define holes or apertures  207  to receive fasteners to secure the retention components  203  to the backplate  128 . The retention component  203  can include a bulge or a raised or protruding portion  206  that forms a space between the backplate  128  and the slot  205  and can at least partially define a retention volume. The raised portion  206  can be sufficiently large to enable a support component  209  (discussed in greater detail below) to be inserted through the slot  205 . In some examples, the retention components  203  can serve as positional datum for the display  208 . That is, the retention components  203  can serve to fix the position or the directional movement of the display  208  relative to the housing  201  along one or more axes or degrees of freedom, such as a vertical axis. For example, the retention components  203  can be useful for field repair because the retention components serve as alignment datum for reassembling the electronic device  200 . Further details of the construction and architecture of the electronic device  200  are provided below with reference to  FIGS. 8A and 8B . 
       FIG. 8A  illustrates a cross-sectional front view of select components of the electronic device  200 . In some examples, the electronic device  200  can include one or more support components  209  that can engage with the retention components  203  to fix the position or directional movement of the display  208  in one or more directions relative to the display housing  201 .  FIG. 8B  illustrates a perspective view of one of the support components. In some examples, the support components  209  can be glued or otherwise affixed to the housing  201 , for example, a surface of the housing  201  that at least partially defines the internal volume. In some examples, the glue  217  (shown in  FIG. 9 ) that can be used to secure the retention components  203  to the backplate  228  and the support components  209  to the housing  201  can be a high strength permanent adhesive, for instance, the glue  217  can have an adhesive shear strength that is greater than 3 MPa. In some examples, the support components  209  can include metal, such as stainless steel. In some examples, the support components  209  can include a sheet of material, such as a sheet of metal, plastic, ceramic, or combinations thereof. In some examples, the support components  209  can include a sheet of steel or aluminum. As illustrated in  FIG. 8B , the support component  209  can define a tab or protruding portion  215 . In some examples, the support component  209  can define holes or apertures (not shown) to receive fasteners to secure the support component  209  to the housing. 
       FIG. 9  illustrates a cross-sectional view of the assembled electronic device  200 . The display  208  (including the cover assembly  211  and backlight unit  213 ) can be secured to the housing  201  by inserting the protruding portion  215  of the support component  209  at least partially into or through the slot  205  of the retention component  203 . In combination with the retention components  203 , the support components  209  can serve as positional datum for the display  208 . For example, the retention components  203  and support components  209  can be useful for field repair because the retention components serve as alignment datum for reassembling the electronic device  200 . In some examples, the connection between the retention components  203  and support components  209  can restrict relative motion between the display  208  and the housing  201  regardless of the orientation of the electronic device  200 . For instance, the retention components  203  and support components  209  can function as intended when the electronic device  200  is in a landscape orientation and also when the device  200  is in a portrait orientation. It will be understood that the placement of the retention components  203  and support components  209  can be reversed. That is, in some examples, the retention components  203  can be secured to the housing  201  and the support components  209  secured to the backplate  228 . 
     Any number or variety of components in any of the configurations described herein can be included in the electronic device. The components can include any combination of the features described herein and can be arranged in any of the various configurations described herein. The structure and arrangement of components of an electronic device having a housing with structures described herein, and defining an internal volume, as well as the concepts regarding engagement and retention features, can apply not only to the specific examples discussed herein, but to any number of embodiments in any combination. Various embodiments of electronic devices including components having various features in various arrangements are described below, with reference to  FIGS. 9-11 . 
     With the ubiquity of cameras that are integrated into personal electronic devices, there is a need for the user to be notified if and when the camera is actively operating. Thus, many electronic devices currently use indicator lights that illuminate when the camera is activated to notify the user that the camera is on. In some examples, illumination components or indicator lights can be used to provide other information to a user, as desired. Depending on the design constraints of the electronic device, however, it may not always be feasible or practical to position an LED directly behind the cover glass to provide a linear optical path therefrom. 
       FIG. 10  illustrates a perspective cross-sectional view of a camera module  300 .  FIG. 11  illustrates a cross-sectional side view of the camera module  300 . The camera module  300  can be used in any number of electronic devices, such as electronic devices  100  and  200  described above. The camera module  300  can include a camera  302  and an indicator light or illumination component  304 . The indicator light  304  can include an LED package  308  electrically connected to a flexible printed circuit or electrical connector  310 . In some examples, the LED package  308  is oriented perpendicular to an outlet  305  of the indicator light  304 . That is, the LED package  308  can emit light in a direction that is orthogonal to the direction the light is ultimately emitted through the outlet  305 . The indicator light  304  can include a light guide or light pipe  306 . The light guide  306  can include any transparent material as desired, such as a transparent polymer. In some examples, the light pipe  306  can include polycarbonate. In some examples, the light pipe  306  defines a light receiving surface positioned opposite the LED package  308 , an angled reflection surface  314 , and a light emitting surface positioned adjacent to the cover  312 . In some examples, the reflection surface  314  is positioned at an acute angle relative to one or both of the light receiving surface and the light emitting surface. In some examples, the reflection surface  314  is positioned at a 45 degree angle relative to one or both of the light receiving surface and the light emitting surface. In some examples a coating  315  is applied to, deposited on, or formed on the reflection surface  314  of the light pipe  306 . The coating  315  can have a high reflectance, and specifically, can be configured to be highly reflective of one or more wavelengths of light emitted by the LED package. For example, the LED package can emit green light having wavelengths between 520 nm and 560 nm and the coating  315  can have a high reflectance value for those wavelengths of light. In some examples, the coating  315  is applied by one or more vapor deposition processes, such as one or more physical vapor deposition (PVD) processes. In some examples, the coating  315  can be a mirror coating, that is the reflective coating  315  can have a reflectance in a desired range of wavelengths of light of greater than 95%, greater than 97%, greater than 98%, greater than 99%, or about 100%. 
     In some examples, the reflective coating  315  can be a multi-layer coating. That is, in some examples, the reflective coating  315  can include multiple layers of the same or different materials. In some examples, the reflective coating  315  can be formed from multiple layers, each deposited by a vapor deposition process. In some examples, the reflective coating  315  can include layers of ceramic material, such as one or more of silicon dioxide (SiO 2 ), titanium dioxide (TiO 2 ), zirconium oxide (ZrO 2 ), or other ceramic materials. In some examples, the reflective coating  315  can include alternating layers of different material. For example, the reflective coating  315  can include alternating layers of a first material and a second, different material. In some examples, reflective coating  315  can include alternating layers of SiO 2  and TiO 2 . In some examples, the reflective coating  315  can include between 1 and 100 layers, between 5 and 50 layers, or between 10 and 30 layers, for example about 25 layers. In some examples, each layer can have a thickness of between 10 nm and 1000 nm, or between 50 nm and 500 nm, for example about 60 nm and/or about 100 nm. In some examples, the reflective coating  315  can have a total thickness of between 500 nm and 5000 nm, or between 1000 nm and 3000 nm, for example about 2000 nm. In some examples, the reflective coating  315  can have a thickness of 2078 nm. 
     In some examples, the light pipe  306  can be overmolded over a reflective film to produce the reflective surface necessary to redirect the light emitted from the LED package  308 . The light pipe  306  can be installed and secured in place via a compression fit once additional components of the device  300  are assembled (e.g., once the backlight unit is installed). In some examples, an air gap  317  exists between the LED package  308  and the light pipe  306 . In some examples, the air gap  317  between the LED package  308  and the light pipe  306  can be between 0.05 mm and 0.5 mm, or between 0.1 mm and 0.2 mm, for example about 0.15 mm. In some examples, the air gap  317  is less than 0.15 mm. In other examples, there is no air gap and the LED package  308  directly abuts or contacts the light pipe  306 . In some examples, an optically clear adhesive (not shown) is positioned between the LED package  308  and the light pipe  304 . The optically clear adhesive can provide additional coupling between the LED package  308  and the light pipe  304 , while still allowing light to pass through substantially uninterrupted. 
     In some examples, the light pipe  306  is positioned in contact with a frame  316 . The frame  316  can be substantially similar to the frame  116  discussed above with reference to  FIGS. 4-6 . In some examples, the frame  316  can define an opening or aperture to receive the light pipe  306 . In some examples, the frame  316  can include an opaque polycarbonate. In some examples, the flexible printed circuit  310  is attached to the frame  316  using an adhesive  318 . In some examples, an opaque ink  320  can be positioned at an interface between the cover  312  and the frame  316 . The opaque ink  320  can surround the outlet  305  such that the redirected light is only emitted through the outlet  305 . 
     Any of the features or aspects of the components discussed herein can be combined or included in any varied combination. For example, the design and shape of the frame or other device components are not limited in any way and can be formed by any number of processes, including those discussed herein. Any components can also be or form any number of additional components of an electronic device, including internal components, external components, cases, surfaces, or partial surfaces.

Additionally, such entities should consider taking any needed steps for safeguarding and securing access to such personal information data and ensuring that others with access to the personal information data adhere to their privacy policies and procedures. Further, such entities can subject themselves to evaluation by third parties to certify their adherence to widely accepted privacy policies and practices. In addition, policies and practices should be adapted for the particular types of personal information data being collected and/or accessed and adapted to applicable laws and standards, including jurisdiction-specific considerations. For instance, in the US, collection of or access to certain health data can be governed by federal and/or state laws, such as the Health Insurance Portability and Accountability Act (HIPAA); whereas health data in other countries can be subject to other regulations and policies and should be handled accordingly. Hence different privacy practices should be maintained for different personal data types in each country. 
     Despite the foregoing, the present disclosure also contemplates embodiments in which users selectively block the use of, or access to, personal information data. That is, the present disclosure contemplates that hardware and/or software elements can be provided to prevent or block access to such personal information data. For example, in the case of advertisement delivery services, the present technology can be configured to allow users to select to “opt in” or “opt out” of participation in the collection of personal information data during registration for services or anytime thereafter. In another example, users can select not to provide mood-associated data for targeted content delivery services. In yet another example, users can select to limit the length of time mood-associated data is maintained or entirely prohibit the development of a baseline mood profile. In addition to providing “opt in” and “opt out” options, the present disclosure contemplates providing notifications relating to the access or use of personal information. For instance, a user may be notified upon downloading an app that their personal information data will be accessed and then reminded again just before personal information data is accessed by the app. 
     Moreover, it is the intent of the present disclosure that personal information data should be managed and handled in a way to minimize risks of unintentional or unauthorized access or use. Risk can be minimized by limiting the collection of data and deleting data once it is no longer needed. In addition, and when applicable, including in certain health related applications, data de-identification can be used to protect a user&#39;s privacy. De-identification can be facilitated, when appropriate, by removing specific identifiers (e.g., date of birth, etc.), controlling the amount or specificity of data stored (e.g., collecting location data a city level rather than at an address level), controlling how data is stored (e.g., aggregating data across users), and/or other methods. 
     Therefore, although the present disclosure broadly covers use of personal information data to implement one or more various disclosed embodiments, the present disclosure also contemplates that the various embodiments can also be implemented without the need for accessing such personal information data. That is, the various embodiments of the present technology are not rendered inoperable due to the lack of all or a portion of such personal information data. For example, content can be selected and delivered to users by inferring preferences based on non-personal information data or a bare minimum amount of personal information, such as the content being requested by the device associated with a user, other non-personal information available to the content delivery services, or publicly available information. 
     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 target 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.
