Description:
CROSS-REFERENCE TO RELATED APPLICATION(S) 
     This claims priority to U.S. Provisional Patent Application No. 62/855,715, filed 31 May 2019, and entitled “DISPLAY ASSEMBLY,” the entire disclosure of which is hereby incorporated by reference. 
    
    
     FIELD 
     The described embodiments relate generally to components for an electronic device. More particularly, the present embodiments relate to components and structures for the assembly of electronics devices. 
     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 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 performance of an electronic device due to an inability to effectively distribute or reject heat generated by the electronic device to the surrounding environment. 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 
     Representative embodiments are illustrated in the accompanying drawings. The following descriptions are not intended to limit the embodiments to one preferred embodiment. To the contrary, they are intended to cover alternatives, modifications, and equivalents that can be included within the spirit and scope of the described embodiments, as defined by the appended claims. 
     One aspect of the present disclosure relates to an electronic device including a housing that defines an internal volume and an exterior surface 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 and a component, such as a daughterboard, extending perpendicularly from the cover. The cover assembly can also include a display unit. The backlight unit can define one or more retention features that can slidably engage with one or more corresponding engagement features affixed to the housing in the internal volume. An engagement feature can be disposed in a receptacle defined by the housing that does not extend past a thickness of the housing at that location. 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, and the one or more daughterboards can extend into the internal volume between the backlight unit and the housing, adjacent to the securing component. The housing can define a recess underlying the daughterboard, and a flexible electrical connector can extend from the daughterboard into the recess, around the periphery thereof, and out of the recess along a path through a space between the backlight unit and the housing. A protrusion can be positioned along, and can extend into, the path near an edge of the recess such that the flexible electrical connector passes over the protrusion. The cover defining the exterior surface, which can be a transparent cover such as glass, sapphire, or plastic, can be fastened to the housing along the periphery by a reworkable pressure sensitive adhesive inserted into a thin gap between the edges of the housing and the cover. 
     Accordingly, various components of an electronic device can be front loaded into and secured to a housing. The components can be retained within an internal volume of the housing without passing retaining hardware through a major surface of the housing, such as the back or rear surface of the housing. In some examples, the housing of an electronic device can include a structure configured to provide a number of desired properties, features, or functionalities. In some examples, passing traditional retention hardware through a major exterior surface of the housing can disrupt or inhibit these desired properties, features, or functionalities. Thus, the components and methods described herein can allow for the assembly of an electronic device including a housing structure without inhibiting the desired properties of the housing structure or undesirably increasing the dimensions of the electronic device. Further, the components and methods described herein can allow for relative ease of assembly and disassembly, for example, to allow for repair or recycling of one or more components of the electronic device. 
     In some examples, the housing structure or structures can include a body defining both a first surface and a second surface. In some examples, the body can be a unitary body, such as a unitary body formed by a single piece, section, or portion of a material. In some examples, however, the body can be formed from, or can include, two or more portions that can be joined together to form the body, for example, by welding, adhering, or bonding. In some examples, one or more cavities, or portions of cavities, can be formed in separate portions of material, whereupon the portions of material can be joined to form a body including patterns of cavities, as described herein. The first surface and the second surface of the body can be opposing surfaces. At least a portion of the body can define a three-dimensional pattern or matrix of apertures or passageways formed therein. In some embodiments, the three-dimensional pattern can extend through at least a portion or a region of the body, or it can extend substantially throughout the entire body. The three-dimensional pattern can extend across one or more of an entire height, width, and/or depth of the body. The three-dimensional pattern or matrix can be formed or defined by a combination of one or more cavities extending into the body from the first surface, and one or more cavities extending into the body from the second surface of the body. 
     In some embodiments, the one or more cavities extending into the body from the first surface can intersect with one or more of the cavities extending into the body from the second surface to form the three-dimensional pattern or matrix. That is, in some examples, the negative space of a cavity extending into the body from the first surface of the body can intersect or interfere with the negative space of one or more cavities extending into the body from the second surface of the body. Further, in some embodiments, the cavities can eccentrically intersect, merge, or interfere to form an aperture. The aperture or apertures can be through-holes in the body, that is, as used herein, the term aperture can refer to a hole in a body that passes entirely through the body. In some embodiments, the three-dimensional pattern of apertures as described herein can have a surface area that is up to twice as large, up to five times as large, up to ten times as large, or even several orders of magnitude larger than the surface area of a similarly sized and shaped body that does not include the three-dimensional pattern of apertures. This high amount of surface area can serve to greatly increase the ability of the body to transport heat away from itself or away from other components of an electronic device in contact with the body, for example, by direct convection to the surrounding air. In some embodiments, the cavities extending into the body from a surface of the body can be arranged in a pattern. This pattern can be a regular or repeating pattern of cavities that extends throughout a portion of a surface, or in some examples, substantially an entire surface of the body. 
     The structures described herein, such as housing structures for electronic devices, can provide for enhanced heat removal relative to traditional housing structures. For example, a structure as described herein acting as a housing for an electronic device can remove relatively large amounts of heat from the electronic device via passive heat transfer to air surrounding the structure by maximizing surface area and providing apertures or passageways that allow air to be driven into or through the device, for example by a fan, to remove even more heat from the electronic device. These enhanced levels of heat removal, as described above, can result in significant performance gains for the electronic device and can allow for the use of components or operating levels that heretofore have not been achievable with traditional housing structures. 
     The structures described herein can also enhance characteristics of other aspects of the electronic devices with which they are associated. For example, when used as a housing or other structural component of an electronic device, a structure as described herein can provide a high level of strength and stiffness to weight ratio to the device. Traditional structures often achieve enhanced stiffness or strength by thickening or enlarging certain portions of the structure, often resulting in an increase in the weight and size of the electronic device, which are not typically desirable to a user. The structures described herein can include, for example, a matrix of passageways that serves to greatly enhance the stiffness of the three-dimensional structure, without significantly increasing the size or weight of the structure. Thus, a relatively lightweight, yet extremely strong and stiff electronic device can be produced. 
     The light weight and stiffness of the structure can also provide a user with a pleasing experience when handling the device. While light weight, the structure is sufficiently rigid and tough to allow the electronic device to be used over a long period of time while maintaining dimensional stability. Additionally, the present structure allows for custom designs to be 3D printed or manufactured that optimize a number of factors including weight, rigidity, heat transfer considerations, and manufacturability. In some examples, a structure as described herein can include a relatively intricate repeating pattern that, in addition to enhancing heat removal capabilities and providing stiffness, provides a visually interesting or aesthetically pleasing effect to the user. Such a structure, for example, when used as a housing, can also include a variety of colors on one or more regions of the housing to enhance the visual appearance and provide a pleasing aesthetic experience to the user. 
     Further, in some embodiments, the structures described herein can act as shielding for the electronic device, while still allowing for air flow therethrough. For example, a structure can act as an electromagnetic interference (EMI) and/or electromagnetic compatibility (EMC) noise shield for one or more components housed therein. In some embodiments, such as where the structure includes a metal and/or conductive material, the structure can provide EMI and/or EMC shielding for one or more electronic components of the device, such as integrated circuits. Thus, in some examples, additional shielding material and/or measures can be eliminated while achieving a desired level of EMI and/or EMC shielding because of the housing structure. This beneficial shielding effect can thus reduce the cost and weight of a device, while providing other enhanced characteristics, as discussed herein. 
     While the housing structures described herein, for example, including a matrix of passageways, can provide enhanced performance and other benefits to an electronic device, traditional hardware and methods for retaining device components typically engage solid housing panels, or otherwise pass-through or disrupt the structure, thereby reducing or inhibiting the benefits provided. The present systems retain the components of an electronic device within an internal volume at least partially defined by a housing including a structure as described herein without passing hardware or retention components through a major surface of the housing. Such a construction allows the structures of the housing, such as a matrix of cavities or passageways, to be relatively uninterrupted by features used to retain components in the structure, thereby maximizing the benefits provided by the structures. 
     The present system allows for very narrow bezels or borders to be formed on display devices, such as liquid crystal display (LCD) devices. 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 present mounting system facilitates front mounting and secure retention of the display components, while maintaining very narrow bezels and borders, without passing fasteners through the rear or side surfaces of the housing. 
     The present mounting system enables the components of an electronic device, such as display components, circuit boards, fans, and other electronic components, to be disposed adjacent 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 destroying the housing and/or components. Accordingly, electronic devices assembled with the present mounting system allows for devices to be disassembled, for example, to repair or replace individual components or to recycle or reuse individual components. 
     In some examples, the design of the components described herein can allow not only for retention in a housing having a structure as described herein, but can also aid in minimizing one or more desired dimensions of the device. For example, it can be desirable to provide an electronic device having a reduced thickness. Traditional mounting and retention hardware can necessitate an arrangement of components that includes unoccupied space in the internal volume, thereby increasing the thickness of the device. The components and methods described herein, however, can allow for a component, such as a backlight unit, to be retained in the internal volume adjacent to a rear major surface thereof, providing for a reduced overall device thickness or a larger available area in the internal volume for additional components. Further, by retaining a component, for example, with retention features defined by the component and engagement features affixed to an internal surface of the housing, there is reduced need for housing material around the periphery to retain the component. This construction can allow for construction of display devices including relatively narrow bezels or borders around the active area of the display. 
     These and other embodiments are discussed below with reference to  FIGS. 1-14 . 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  shows an example electronic device  100  that can include a structural housing and front mounted components, as detailed herein. The electronic device  100  shown in  FIG. 1  is a display or monitor, for example, as can be used with a 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 keyboard  110 , a mouse  120 , a track pad, a stylus, a microphone, or any combination of input devices. Further details of the electronic device  100  are provided below with reference to  FIGS. 2A-2B . 
     Referring now to  FIG. 2A , 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 include a body defining a first surface and a second surface. At least a portion of the body can include a three-dimensional pattern or matrix of apertures or passageways as described herein. The electronic device  100  can further include a backplate  110  that can be disposed adjacent to a major surface of the housing  101  at least partially defining the internal volume. In some examples, such as where the housing  101  includes a matrix of passageways, the backplate  110  can serve to seal the internal volume from an exterior or ambient environment that might otherwise be accessible through the passageways. In some examples, this seal can be substantially watertight or airtight and can prevent or significantly inhibit the passage of dust or other particulate matter from the ambient environment into the internal cavity of the device  100 . 
     In some examples, the backplate  110  can also 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  110  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  110  can include metal, ceramic, polymer, or combinations thereof. The backplate  110  can define one or more apertures  111  that can be sized to receive a portion of an engagement feature  112 , for example, a post of an engagement feature  112  as described herein. In some examples, the engagement feature or features  112  can secure the backplate  110  to the housing  101  and can further seal the backplate  110  and the housing  101  at the location of the apertures  111 . Although referred to separately as a housing  101  and a backplate  110 , in some examples, the housing  101  and the backplate  110  are referred to together as a housing. 
     The electronic device  100  can further include a display component  120 , for example, a backlight unit  120 . Although illustrated as a backlight unit, the display component  120  can include substantially any desired display or device component. In some examples, the backlight unit  120  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, printed circuit boards, and a baseplate, as will be described further herein. A portion of the backlight unit  120 , such as a rear major surface thereof, can define one or more retention features (not shown) that correspond to and can slidably engage with the engagement features  112  protruding from the backplate  110 , as will be described herein. 
     The backlight unit  120  can be relatively heavy compared to other components of the device  100 , so multiple engagement features  112  can be affixed to, and protrude from, the housing  101  to engage the retention features of the backlight unit  120  and evenly support its weight over a large area of the housing  101 . Further, the design of the housing  101 , backplate  110 , and the engagement features  112  can allow for intimate thermal contact between the backlight unit  120  and the backplate  110 , thereby providing for increased thermal conduction and improved device cooling. During assembly, the backlight unit  120  can be lowered or inserted into the internal volume so that the engagement features  112  can pass into the retention features, whereupon the backlight unit  120  can be laterally translated to complete engagement of the engagement features  112  with the retention features to secure the backlight unit  120 , as will be described in further detail below. As the backlight unit  120  can be securely connected to the housing  101  via the engagement features  112 , the number of additional features or securing components disposed around a periphery of the backlight unit  120  can be reduced, thereby allowing the backlight unit  120  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 electronic device  100  can also include a cover assembly  130 . The cover assembly  130  can include a cover  132 , which can at least partially define an exterior surface of the device  100 . The cover can be any desired transparent material, for example, glass, plastic, sapphire, or other transparent materials. In some examples, a display unit can be adhered to the cover  132 , for example, to a surface of the cover  132  opposite the surface defining an exterior surface of the device  100 . In some examples, the display unit can be an LCD unit, although in other examples any form of display unit can be used as desired, such as an LED display unit, OLED display unit, plasma display unit, quantum dot display unit, and other display units. The display unit can be affixed to the cover by gluing, adhering, or any other desired securing technique. Further, in some examples, the cover  132  can cover additional components such as a camera, or a touch sensitive surface such as a touchscreen. 
     The cover assembly  130  can further include a display component  134  extending from the cover  132 . In some examples, the display component  134  can include one or more electronic components, such as printed circuit boards including processors, memory, and other electrical components, and can be referred to as daughterboards. The daughterboards  134  can be electrically connected to the display unit, for example, by a flexible electrical connector, and can drive or control the display unit. The daughterboards  134  can extend substantially perpendicularly from the cover  132 , and can be mounted or affixed to the cover  132 . In some examples, a bracket can be glued or otherwise affixed to the same side of the cover  132  as the display unit to maintain the daughterboards  134  in a position perpendicular to the cover  132 . In some examples, the bracket can include metal, such as stainless steel. Additional electrical connectors (not shown), such as flexible electrical connectors, can extend from the daughterboards  134 , as will be described herein. 
     In an assembled state, the daughterboards  134  can be disposed in the internal volume in a space between the backlight unit  120  and a sidewall of the housing  101 . The cover  132  can be fastened to the housing  101 , for example, along a periphery thereof by a reworkable adhesive that can be provided through a gap between the exterior surface of the housing  101  and the cover  132 , as described further herein. Any number of additional internal components can be disposed between the housing  101  and the cover assembly  130 . The housing  101  can define at least a portion of an exterior surface of the device  100 . The cover  132  can define a front exterior surface of the device  100 . Together, the housing  101  and the cover  132  can substantially define the exterior surface and/or the internal volume of the device  100 . 
     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  132 , 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  130 . Additional features of the housing  101  are provided below with reference to  FIG. 2B . 
       FIG. 2B  shows a front view of the housing  101  of the electronic device  100 . The housing  101  can be formed from, or can include, regions having a structure as described herein. The structure, such as a structure formed in regions of the housing  101 , can include a body having a first surface forming a portion of the exterior of the electronic device  100  and a second surface defining at least part of an internal volume of the housing  101 . Additionally, other components of the electronic device  100 , such as internal structural components, can be formed from, or can include, regions having a structure as described herein. The structure, such as a structure formed in regions of the housing  101 , can include one or more cavities extending into the body from a first surface of a body and one or more cavities extending into the body from a second surface of the body. The one or more cavities extending into the body from the second surface of the body can intersect with, or interfere with, one or more cavities extending into the body from the first surface of the body to form a three-dimensional pattern of apertures or passageways  102  in the body. 
     The body of a structure, for example, a contiguous structure, can include one or more structures or features formed in, defined by, or extending into the body from one or more of the surfaces of the body. For example, the body can have a generally cuboid shape, a generally spherical shape, a generally cylindrical shape, a generally toroidal shape. In some examples, the body can have a general shape of any polyhedron. In some other embodiments where the three-dimensional pattern extends through one or more regions of the body, the regions can be separated by one or more portions of the body  103  that do not include the three-dimensional pattern. The one or more portions  103  separating the regions of the body that include the three-dimensional pattern or apertures  102  can be substantially continuous. In some embodiments, however, the one or more portions  103  can include structures or features formed in or on the one or more portions  103 . As used herein, the term three-dimensional pattern can refer to a positive surface of a structure, or a negative space at least partially enclosed or defined by a surface or a body. The three-dimensional pattern can include one or more irregular shapes, regular shapes, repeating shapes, or combinations thereof. 
     In some embodiments, a structure of the housing  101  can include, or be formed from, any machinable or formable material. For example, a structure can include or be formed from a material such as a metal, a ceramic, an amorphous material such as glass or an amorphous metal, a polymer, or combinations thereof. In some embodiments, a structure is a metal. In some embodiments, the metal can be an elemental metal or a metal alloy. In some embodiments, the structure can include metals such as aluminum or steel. For example, the structure can be aluminum or an aluminum alloy. In some embodiments, the structure can include a 6000 series aluminum alloy, for example, a 6060, 6061, or 6063 aluminum alloy. In some embodiments, for example, where the structure includes a metal and/or conductive material, the structure can act as an EMC/EMI noise shield 
     The structures described herein, for example, as used in the housing  101  of the electronic device  100 , can be formed by a variety of methods and processes. In some embodiments, a structure can be formed by additive and/or subtractive methods such as etching, machining, casting, stamping, forging, forming, injection molding, or the like. Further, multiple methods of forming structures can be employed to form a single structure. For example, one or more cavities extending into the body from a first surface of the body of a structure can be formed by a stamping, a molding, or another forming process, while one or more cavities extending into the body from a second surface of the body of the structure can be formed by a machining or an etching process. 
     As discussed with respect to  FIG. 2A , a number of engagement features  112  can be affixed to the housing  101  at a variety of locations. These engagement features  112  can, for example, be received by receptacles  104  formed in or defined by the housing  101 . Further, the receptacles  104  can have a depth that is less than a thickness of the housing  101  at that location. That is, each receptacle  104 , in some examples, does not extend all the way through the housing  101 . Accordingly, the engagement features  112  can be affixed to the housing so that they protrude into the internal volume defined by the housing, for example, to support and engage with one or more components, as described herein. 
     In some examples, the engagement features  112  can be distributed across a major surface of the housing  101 , for example, a planar major surface surrounded by sidewalls that at least partially defines an internal volume of the device. In some examples, however, the engagement features  112  can be positioned on substantially any surface of the housing  101  that at least partially defines the internal volume. The distribution of the engagement features  112  across an area of the housing  101  can serve to effectively distribute the weight of any components engaged with the engagement features  112  across the housing  101  and can reduce the likelihood of failure of the engagement features when under high stress, for example, during a drop event. The electronic device  100  can include any number of engagement features  112 , for example, 1 or more, 5 or more, 10 or more, 20 or more, 30 or more, 50 or more, or even 100 or more. In some examples, the electronic device  100  can include 30 or 32 engagement features  112 . 
     In the present example, the engagement features  112  can be positioned at locations on the structure of the housing  101  between the apertures  102  of a continuous matrix of apertures  102 . That is, an engagement feature  112  can be positioned such that the receptacle extends into the body of the housing  101  from a first surface at a location between cavities extending into the body from the first surface and between cavities extending into the body from a second, opposite surface. In some examples, the engagement features  112  can be positioned at locations on a structure including a matrix of aperture or passageways  102  where the structure has a thickest amount of material. Other factors, such as structural considerations, component placement, and thermal considerations can also influence desired location selection for one or more of the engagement features  112 . 
     In some embodiments including a backlight unit  120  having retention features that engage with the engagement features  112 , the locations of the retention features and/or the locations of internal components of the backlight unit  120  can influence a desired location of the engagement features  112 . In some examples, as described herein, a backlight unit  120  can include internal posts  125  that maintain a thickness of the backlight unit  120  and can carry a load exerted on a major surface of the backlight unit  120  to an opposite major surface thereof. For example, if a force is exerted on the front major surface of the backlight unit  120 , such as by a user accidentally exerting pressure on the front of the electronic device  100 , the load generated by the force on the backlight unit  120  can be transferred to a rear major surface thereof through one or more posts  125  and into the housing  101  of the device from the backlight unit  120  via the engagement features  112 . Accordingly, such a load is transferred from a post  125  through the components of the backlight unit  120  to which the post  125  is affixed, and to the nearest engagement feature or features  112 . As such, it can be desirable to minimize a distance between the posts  125  and the engagement features  112  in order to reduce the amount, kind, or width of components of the backlight  120  through which load is transferred. In order to achieve this, the engagement features  112  and the receptacles  104  can be positioned on the housing  101  at locations that are near to the posts  125  of the backlight unit  120  when the device  100  is in an assembled state. 
     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. 3-6 . 
       FIG. 3  shows a perspective view of a housing  201  of an electronic device  200  including a backplate  210  affixed thereto, and one or more engagement features  212  passing through the backplate  210  and into the housing  201 . The housing  201  can be substantially similar to, and can include any of the features of, the housing  101  described with respect to  FIGS. 1-2B , while the backplate  210  and engagement features  212  can be substantially similar to the backplate  110  and engagement features  112  described above with respect to  FIGS. 1-2B . 
     In some embodiments where an electronic device  200  is a display device, it can be desirable to prevent the ingress of dust, contaminants, and/or other particulate matter from entering the internal volume  206  defined by the housing  201 . For example, dust or particles can undesirably enter the device and migrate in front of the active area of the display, whereupon they can be visible to a user and can cause an undesirable distraction from the display content. In some examples, the housing  201  can have a structure as described herein including a matrix of passageways that allow fluid communication between an interior volume  206  and an ambient environment, for example, to promote airflow there through, and to facilitate device cooling. Accordingly, it is desirable for the backplate  210  to substantially seal the internal volume  206  of the device  200 . In some examples, the backplate  210  and housing  201  can provide the internal volume  206  with a substantially watertight or airtight seal. 
     Further, in some examples, it is desirable for the backplate  210  to substantially abut a surface of the housing  201  from which one or more cavities extend to form a matrix of passageways, as described herein. In such cases, the backplate  210  can aid in conducting heat from components positioned in the internal volume  206  to the structure of the housing  201 , whereupon the heat can be emitted into the ambient environment, as described herein. Accordingly, in some examples, the backplate  210  can include a substantially thermally conductive material, such as a metal, for example, a stainless steel alloy. 
     The backplate  210  can be affixed to the housing  201  by the engagement features  212 . Although the backplate  210  can include apertures through which the engagement features  212  can pass, the engagement features  212  themselves can provide an effective dust seal at these locations. In some examples, additional materials, such as a pressure sensitive adhesive, can be applied at or near the apertures to further facilitate this seal. In addition to sealing the interior volume  206  at the apertures in the backplate  210 , it can also be desirable to seal the backplate  210  against the housing  201  along a periphery of the backplate  210 . Components and methods for achieving this seal are described further with respect to  FIG. 4 . 
       FIG. 4  shows a front view of the housing  201  of  FIG. 3  having a matrix of apertures or passageways  202  and seal materials  241 ,  242 ,  243 ,  244  positioned at the periphery of the structures of the housing  201 , adjacent to the sidewalls. The seal materials  241 ,  242 ,  243 ,  244  can serve to seal the internal volume  206 , as described herein, when the backplate  210  is positioned thereover and affixed to the housing  201 . In some examples, the seal materials  241 ,  242 ,  243 ,  244  can include substantially any compliant, flexible, and/or deformable material capable of providing an air or water tight seal between two rigid bodies. For example, the seal materials  241 ,  242 ,  243 ,  244  can include a foam, such as a polymer foam. Although the present example includes four approximately “L” shaped pieces of foam  241 ,  242 ,  243 ,  244 , it should be understood that substantially any shape, size, and amount of seal material can be used to seal the backplate  210  against the housing  201  about the periphery of the backplate  210 . 
     As can be seen in  FIG. 4 , in some examples, the foam pieces  241 ,  242 ,  243 ,  244  do not directly contact one another, and a small gap or space can be present between each individual foam piece  241 ,  242 ,  243 ,  244 . These gaps or spaces can themselves be sealed with one or more components, as described below with reference to  FIGS. 5 and 6 . 
       FIG. 5  shows a front view of the housing  201  including the backplate  210  affixed thereto by the engagement features  212 . The backplate  210  can overlay or overlap the foam pieces  241 ,  242 ,  243 ,  244  and can cooperate with them to form the seal between the backplate  210  and housing  201 . Further, components  251 ,  252 ,  253 ,  254  can be used to aid in securing the backplate  210  to the housing  201 , and to complete the seal therebetween at the gaps between the foam pieces  241 ,  242 ,  243 ,  244 . In some examples, the components  251 ,  252 ,  253 ,  254  can pass through an aperture or cut-out in the backplate  210 , whereupon they can be received by and retained in the housing  201 . In some examples, the components  251 ,  252 ,  253 ,  254  can be screws, posts, bolts, or any other desired component. 
       FIG. 6  illustrates a cross-section of the housing  201  and the backplate  210  shown in  FIG. 5 , taken along a portion including the component  253  and foam pieces  243 ,  244 . As can be seen, the backplate  210  can overlap or interfere with the foam pieces  243 ,  244  and can depress or deform the foam pieces  243 ,  244  to provide a sufficient seal capable of, for example, preventing the ingress of dust or moisture. In some examples, additional material such as adhesive material, for example, a pressure sensitive adhesive  263 ,  264 ,  267 ,  268  can be disposed between the foam pieces  243 ,  244  and the backplate  210  and/or between the component  253  and the backplate  210 . The pressure sensitive adhesive  263 ,  264 ,  267 ,  268  can serve to further reinforce the seal at those locations to which it is provided, for example, to enable an air or water tight seal, while still allowing for a desired level of ease of removal of components from the device, such as the backplate  210 . Various embodiments of electronic devices including components having various features in various arrangements are described below, with reference to  FIGS. 7A-9D . 
       FIG. 7A  shows a perspective view of a portion of a backplate  310  of an electronic device, including an engagement feature  312  passing through the backplate  310 . The backplate  310  and the engagement feature  312  can be substantially similar to the backplate  110 ,  210  and engagement features  112 ,  212  described with respect to  FIGS. 1-6 . A portion of the engagement feature  312  can pass through an aperture in the backplate  310 , whereupon it can be received by and retained in the housing. 
       FIG. 7B  shows an isometric view of the engagement feature  312 . The engagement feature  312  can include a base  315 , and a post  316  extending therefrom. Referring again to  FIG. 7A , the post  316  can pass through an aperture in the backplate  310  to be received by the housing or an underlying component, while the base  315  is larger than the aperture and can be positioned substantially adjacent to a surface of the backplate  310 . Although illustrated as having a cylindrical shape, the base  315  can have any desired shape as long as it is wider than the post  316  and the aperture through which the post  316  can pass. While not illustrated in  FIG. 7B , any number of engagement features, such as threads, channels, tracks, lobes, or holes can be formed in or on the post  316  to couple or otherwise secure the engagement feature  312  to the housing. The base  315  can include a first surface that can contact or abut the backplate  310  during use, and an opposing second surface on which a component engaged with the engagement feature  312  can be supported, thereby transferring a load from the component to the backplate  310  or housing. The base  315  can, in one example, have a diameter or width of about 6 mm and the post  316  can have a length of about 4 mm, although any desired diameter or length can be used. 
     The engagement feature  312  can further include a top portion or head  313  that can be connected to the base  315 , for example, by a shaft  314 , shown in  FIG. 7C . As described further herein, the head  313  can be sized to correspond to an aperture of a retention feature formed in a component of an electronic device, such as a backlight unit. The head  313  can have any desired shape, and in some examples, can be circular or hexagonal. Further, the head  313  can have a diameter or width that is less than the diameter or width of the base  315 , for example, about 4 mm, although any desired dimension can be used. The head  313  can also include a slanted, curved, chamfered, or beveled edge  317  along all or a portion thereof. In some examples, this bevel can allow a retention feature of a component, such as a backlight unit, to be lowered onto the engagement feature  312  at an angle, for example, during an assembly process, as described herein. The head  313  can also have a thickness of about 0.5 mm, although any desired thickness can be used. 
     The shaft  314  connecting the head  313  to the base  315  can be any desired shape, although in some examples, it can be circular or cylindrical. As described further herein, the shaft  314  can have a width or diameter corresponding to an orifice or aperture of a retention feature, and can have a diameter or width less than a diameter or width of the head  313 . For example, the shaft  314  can have a diameter of about 1.5 mm, although any desired dimension can be used. As can be seen in  FIG. 7C , in some embodiments, the base  315  can have a tiered or stepped structure including a lower portion  318  that has a smaller diameter or width than a main portion  319 . In some examples, this lower portion  318  can define the surface that abuts an adjacent component, such as a backplate  310 . The lower portion  318  can have a diameter of about 4 mm and a thickness of about 0.5 mm, although any desired dimensions can be used. 
       FIG. 7D  shows a top view of the engagement feature  312  including the head  313  and the base  315 .  FIG. 7D  illustrates that the diameter or width of the head  313  is less than the diameter or width of the base  315  so that an orifice or aperture of a retention feature sized to correspond to and pass over the head  313  will not be able to pass over or receive the base  315  of the engagement feature  312 . This size coordination results in the engagement feature  312  supporting the component that defines the retention feature, as described further herein. Additional details of the display components are provided below, with reference to  FIG. 8 . 
       FIG. 8  shows a rear view of a display component of an electronic device, for example, a backlight unit  320 . The backlight unit  320  can be substantially similar to the backlight unit  120  described with respect to  FIGS. 1-2B . While the front or active surface (not shown) of the backlight unit  320  can include a number of components, such as LEDs and reflectors,  FIG. 8  illustrates a rear surface of the backlight unit  320  including a carrier plate  321 , on which the components of the backlight unit  320  can be disposed or carried. In some embodiments, the carrier plate  321  can include or be formed from metal, polymer, ceramic, or combinations thereof. In some examples, the carrier plate  321  can include a thermally conductive material, such as metal, for example, stainless steel. The carrier plate  321  can facilitate the transfer of heat from the components of the backlight unit  321  to other parts of the device, such as the housing, as described herein. 
     As can be further seen in  FIG. 8 , the carrier plate  321  of the backlight unit  320  can at least partially define one or more retention features  322 . A retention feature  322  can include an aperture or an orifice defined by the carrier plate  321 , as described in further detail herein. In some examples, the number and position of the retention features  322  can correspond at least to the number and position of the engagement features of the device, such as engagement features  112 ,  212 , and  312  described herein. Accordingly, in some examples, the carrier plate  321  can define 30 or 32 retention features  322 . Alternatively, the number and position of the retention features  322  can be greater than that of the engagement features, provided that there is a retention feature corresponding to each engagement feature  112 ,  212 , and  312 . Additional details of the retention features is provided below, with reference to  FIGS. 9A-9D . 
       FIG. 9A  shows a view of one such retention feature  322 , as defined by the carrier plate  321  of the backlight unit  320 . In this example, the carrier plate  321  can define a first orifice or aperture  323 , and a second orifice or aperture  324  having a diameter smaller than a diameter of the first orifice  323  that intersects with or overlaps with the first orifice  323 . Although illustrated has having circular shapes, the orifices  323 ,  324  can have substantially any shape, and can further correspond to the shape of the head  313  and shaft  314  of a corresponding engagement feature  312 , as described herein. The first orifice  323  and the second orifice  324  can overlap with one another to form a single opening or orifice of the retention feature  322 , similar to a key-hole profile. In some examples, the portion of the carrier plate  321  defining the retention feature  322  can have a chamfered or beveled edge  325  to facilitate assembly of the device and engagement of an engagement feature  312  with the retention feature  322 . 
       FIG. 9B  shows the retention feature  322  aligned with a corresponding engagement feature  312  prior to an engagement therebetween. As can be seen, the diameter of the first orifice  323  can be the same or a slightly larger diameter than the diameter of the head  313 , to allow the head to pass completely through the first orifice  323  during insertion. The diameter of the first orifice  323  can also be smaller than the diameter of the base  315  so that the carrier plate  321  can abut the base  315  when the engagement feature  312  is fully received by the retention feature  322 . Further, the diameter of the second orifice  324  can be less than the diameter of the head  313  and equal to or greater than the diameter of the shaft  314  so that the head  313  and base  315  extend outside the perimeter of the second orifice  324 , when the shaft  314  is positioned therein. 
     In order to engage the engagement feature  312  and retention feature  322 , as shown in  FIG. 9C , the head  313  of the engagement feature  312  is passed through the first orifice  323  until the base  315  abuts the carrier plate  321 . During assembly of a device including a backlight unit  320  and engagement features  312 , this can be achieved by lowering the backlight unit into the internal volume in a position where the first orifice  323  of the retention features  322  are aligned with the engagement features  312 , as described further herein. In the position illustrated in  FIG. 9C , the backlight unit  320  including the carrier plate  321  defining the retention feature  322  can be removed from the engagement feature  312  by moving the backlight unit along the axis defined by the shaft  314 , to pass the head  313  back out of the retention feature  322 . 
       FIG. 9D  illustrates the engagement feature  312  fully engaged with the retention feature  322  to retain the backlight unit  320 . As can be seen, the backlight unit  320  has been translated laterally relative to the engagement feature  312 , for example, by sliding, so that the retention feature  322  is also translated laterally relative to the engagement feature  312  in such a way that the shaft  314  is disposed in the second orifice  324 . As shown in  FIG. 9D , when the engagement feature  312  and retention feature  322  are arranged in this position, the carrier plate  321  is positioned between the head  313  and the base  315  of the engagement feature so that any movement of the carrier plate  321 , and thus backlight unit  320 , along the axis of the shaft  314  is prevented, thereby retaining the backlight unit  320  on the housing to which the engagement feature  312  is attached. Various embodiments of electronic devices including components having various features in various arrangements are described below, with reference to  FIGS. 10A-10C . 
       FIG. 10A  shows a cross-sectional view of an electronic device  400 . The electronic device  400  can be substantially similar to the electronic device  100 ,  200  described with respect to  FIGS. 1-6 . The electronic device  400  can be, for example, a display device and can include a housing  401  including a matrix of passageways  402  that at least partially defines an internal volume  406  of the device  400 . The housing  401  can be substantially similar to the housing  101 ,  201  described herein with respect to  FIGS. 1-6 . The device  400  can also include a backplate  410 , engagement features  412 , and a backlight unit  420 . The backplate  410  can be substantially similar to the backplate  110 ,  210  described with respect to  FIGS. 1-6 , while the backlight unit  420  can be substantially similar to the backlight unit  120 ,  320  described with respect to  FIGS. 1-2B and 8-9D  and the engagement feature  412  can be substantially similar to the engagement feature  112 ,  212 ,  312  described with respect to  FIGS. 1-9D . 
       FIG. 10A  shows the device  400  during a stage of assembly where the backlight unit  420  has been inserted into the internal volume  406  so that the head  413  of the engagement feature  412  passes through the retention feature  422  defined by the backlight unit  420  and the shaft is still in the first orifice  423  of the retention feature  422 . In the example illustrated in  FIG. 10A , the backlight unit  420  can be lowered into the internal volume  406  in a vertical manner, or by tilting the backlight unit  420  into the internal volume from an initial starting angle. Further, although only one engagement feature  412  and retention feature  422  are illustrated, it should be understood that the device  400  can include any number of features  412 ,  422 , as described herein. 
     As shown, the post of the engagement feature  412  can extend through the backplate  410  and into a receptacle  403  defined by the housing  401 . The receptacle  403  can extend into the housing  401  from a surface at least partially defining the internal volume  406 , and can have a depth less than a thickness of the housing  401  at that location. The position of the receptacle  403  between the cavities that make up the matrix of passageways  402  can also be seen. In some examples, the receptacle  403  can be threaded and the post can include threads corresponding to the threads of the receptacle  403  that mesh to secure the engagement feature  412  to the housing  401 . In some examples, the engagement feature  412  can additionally or alternatively be secured in the receptacle by other methods, such as by brazing, welding, other attachment features, or by an adhesive. 
     The housing  401  can also include a lip  404  extending from a sidewall at least partially defining the internal volume  406 . The lip  404  can extend a desired distance away from the sidewall, and in some examples, can extend substantially perpendicularly therefrom into the internal volume  406 . The lip  404  can be sized, in some examples, so that a distance between the lip  404  and the opposing sidewall of the housing  401  is equal to, or greater than, a height or width of the backlight unit  420 , thereby allowing the backlight unit  420  to be inserted horizontally into the internal volume  406  past the lip  404 . In other examples, the backlight unit  420  can be inserted under the lip  404  and pivoted into the internal volume  406   
       FIG. 10B  shows a subsequent stage in the assembly process of the device  400  whereupon the backlight unit  420  has been translated laterally, for example, by sliding, so that the lip  404  now overhangs or overlaps at least a portion of the backlight unit  420 . Thus, the backlight unit  420  is now positioned within the internal volume  406  so that a portion of the backlight unit  420  occupies the space under the lip  404 , and a gap or space  405  having a size corresponding to the size of the lip  404  is present between a sidewall of the housing  401  and the backlight unit  420  at a location opposite the sidewall including the lip  404 . In some examples, the backlight unit  420  can abut the housing  401  under the lip  404 . In some other examples, however, additional components, such as rubber bumpers, springs, or other compressible biasing members can be positioned between the housing  401  and the backlight unit  420  at this location to provide a biasing force against insertion of the backlight unit  420  directly abutting the housing  401  under the lip  404 . 
     In some examples, the lip  404  can extend from a top sidewall of the housing  401 , that is, a sidewall defining a top surface of the internal volume  406  when the device  400  is in an orientation for use by a user. The lip  404  can also extend any appropriate distance, including about 1 mm, about 2 mm, about 3 mm, about 5 mm, or about 10 mm from the sidewall. Thus, the space between the installed backlight unit  420  and the sidewall of the housing  401 , opposite the lip  404 , can also be about 1 mm, about 2 mm, about 3 mm, about 5 mm, or about 10 mm. 
     While the carrier plate of the backlight unit  420  can define the retention feature  422  as described with respect to  FIGS. 8-9D , components of the backlight unit  420  positioned adjacent to the carrier plate can also have a portion removed therefrom or can define an aperture at a location adjacent to the retention feature. For example, a printed circuit board can be positioned adjacent to the carrier plate, and a portion of the printed circuit board adjacent to the retention feature  422  can also have an aperture therein, or can have at least a portion removed therefrom. While the engagement feature  412  does not, in some examples, extend into the aperture of the printed circuit board when the engagement feature  412  is within the retention feature  422 , the removal of a portion of the printed circuit board can prevent wear or the creation of debris caused by abrasion from the sliding of the backlight unit  420  relative to the engagement feature  412  at that location, thereby reducing the risk of particulate matter or debris being present in the internal volume  406 . 
     Additionally, the retention feature  422  can be positioned at a location on the backlight unit  420  that can be between the internal components thereof. For example, if the backlight unit  420  includes reflectors, such as a cavity reflectors, the retention feature  422  can be positioned at a location on the backlight unit  420  that is disposed between the cavity reflectors. This can ensure that the engagement feature  412  is not at risk of abutting or interfering with the cavity reflectors. Additionally, the position of the engagement features  412  on the housing correspond to the position of the retention features  422 , so the engagement feature positions can also be selected to be positioned between the cavity reflectors of the backlight unit  420 . 
     The lateral translation or sliding of the backlight unit  420  relative to the housing  401  can also cause the retention feature  422  to translate with respect to the engagement feature  412  to fully engage the engagement feature  412  and the retention feature  422 , as described with respect to  FIGS. 9B-9D . In other words, the translation of the backlight unit  420  relative to the housing  401 , illustrated in  FIGS. 10A and 10B , can simultaneously cause the translation between the retention feature  322  and the engagement feature  312  illustrated in  FIGS. 9C and 9D . Accordingly, movement of the backlight unit  420  relative to the housing along the axis of the shaft of the engagement feature  412  is prevented. 
     While movement along the axis of the shaft of the engagement feature  412  is prevented by the configuration shown in  FIG. 10B , additional components can be inserted or incorporated to prevent lateral motion of the backlight unit  420  relative to the housing  401 , such that the engagement features  412  could not unintentionally disengage from the retention features  422 . Accordingly, a securing component or components  407 ,  408  can be positioned between the backlight unit  420  and the housing  401 , as shown in  FIG. 10C . 
     In some embodiments, a securing component can include a shaft or a pin  407  and a shim  408  that are inserted into or positioned in the space between the backlight unit  420  and a sidewall of the housing  401 . The pin  407  can include a threaded portion that can extend into and engage with corresponding threads in the housing  401 , although other forms of retaining the pin  407  can be used. The pin  407  is positioned so that it abuts a portion of the backlight unit  420 . When the device is in use, the pin  407  can support some or all of the weight of the backlight unit  420 , and can prevent the backlight unit from unintentionally translating relative to the housing  401 , such that the backlight unit might disengage from the engagement features  412 . 
     In some examples, a shim  408  can be position in a space or gap between the pin  407  and a sidewall of the housing  401 . The shim  408  can contact or abut both a first surface of the pin  407  and the housing  401 . Further, the shim can include a lip or a flange  409  that extends from a body of the shim  408  to abut a second surface of the pin  407 . This flange  409  of the shim  408  can, for example, prevent the pin from unintentionally backing out of the housing  401 . 
     The device  400  can include a pin  407  and a shim  408  positioned at each of the lower corners of the device, when in an orientation configured for use by a user. While any number of securing components can be used, in some examples, the device  400  can include 2 securing components, each positioned at or near a lower corner of the device, and including both a pin  407  and a shim  408 . As the securing component can support some or all of the weight of the backlight unit  420 , in some examples, a securing component can include a relatively strong material, such as relatively strong metal, plastic, ceramic, or combination thereof. In some examples where the securing component includes both a pin  407  and a shim  408 , the pin  407  and the shim  408  can include a metal such as stainless steel. Further, because the securing component can occupy the entire gap or space between the backlight unit  420  and the housing  401 , the securing component can effectively transfer load from the backlight unit  420  directly into the housing without breaking or deflecting, for example, during a drop event. Details regarding the configuration of the finally assembled device  400  are detailed below, with reference to  FIGS. 11-12C . 
       FIG. 11  shows a perspective view of an electronic device  500  in a state of assembly. The electronic device  500  can be substantially similar to electronic device  100 ,  200 ,  400  described herein, and can be a display device including a component such as backlight unit  520  secured to a housing  501 , for example, as described with respect to backlight unit  420  and housing  401  in  FIGS. 10A-10C . The device  500  can also include a cover assembly  530  that can be substantially similar to cover assembly  130 , and can include a cover  532  and a component such as one or more daughterboards  534 , extending in a substantially perpendicular orientation therefrom. The cover assembly  530  is shown positioned relative to the housing  501  and backlight unit  520  of the device  500 , prior to fixture thereto. 
       FIG. 12A  shows a cross-sectional view of the device  500  shown in  FIG. 11 , including the housing  501 , backplate  510 , backlight unit  520  and cover assembly  530 . The cover assembly  530  can include a cover  532  that can include a display unit, such as an LCD display unit affixed thereto, as described herein. The cover assembly  530  can also include daughterboards  534  that are attached to a bracket  533  that is attached to, and extending from, the cover  532  to hold the daughterboards  534  substantially perpendicular to the cover  532  to facilitate assembly of the device  500 , as described herein. The bracket  533  can be adhered or coupled directly to a portion of the cover  532 , such as a cover glass, or to other locations on the cover  532 . The daughterboards  534  can be electrically connected to the cover  532 , for example, to a display unit thereof. Additionally, a flexible electrical connector  535  can extend from the daughterboards  534  into the internal volume  506  in a channel  508  between the backlight unit  520  and the housing  501 , where it can be connected to one or more components. 
     The housing  501  can define a recess  503  that can be disposed below or adjacent to the daughterboards  534  when the device  500  is in a fully assembled state, as described further herein. The portion of the housing  501  defining the recess  503  can be rounded, substantially cylindrical, or spherical, such that a periphery of the recess  503  has a rounded shape or incorporates a radius on its peripheral profile. In some examples, the recess  503  can have a diameter of about 8 mm, although any desired dimension can be used. Additionally, the recess  503  can be disposed between the securing elements of the device  500 , for example, between two securing elements positioned at lower corners of the device  500  as described with respect to  FIG. 10C . A bump or protrusion  512  can also be disposed on or be defined by the housing  501  at a location near or adjacent to the recess  503  under the backlight component  520 . 
       FIG. 12B  shows the device  500  including the cover assembly  530  positioned in its assembled configuration. This position of the cover assembly  503  can be achieved by rotating the cover assembly  530  relative to the housing  501  from the position shown in  FIG. 12A , and lowering the cover assembly  530  towards the housing  501  until the position illustrated in  FIG. 12B  is achieved. As shown in  FIG. 12B , the recess  503  and the protrusion  512  can allow the flexible connector  535  to be pushed into the internal volume  506  in a manner such that the flexible connector  535  rolls around the periphery of the recess  503  and over the protrusion  512 , rather than merely crumpling or buckling during insertion. In this way, problems caused by the irregular or undesired crumpling, buckling, or movement of the flexible connector  535  can be reduced, while the flexible connector  535  can be retained in a desired location in the internal volume  506 . 
     Further, the flexible connector  535  can exert a spring force in this position such that the flexible connector  535  attempts to enter a flat or straight state, but is prevented from doing so by the recess  503 . The flexible connector  535  can exert a force against the recess  503  and can be positioned against a periphery thereof, for example, a portion or an entire periphery thereof. Accordingly, the flexible connector  535  can extend in a first direction from the daughterboards  534  towards and into the recess  503 , whereupon the flexible connector  535  can bend around a periphery of the recess  503  and exit therefrom in a second direction that can be angled or perpendicular to the first direction. The flexible connector  535  can extend in this second direction along a channel  508  between a component, such as the backlight unit  520 , and the housing  501  that can include the protrusion  512 . Thus, the flexible connector  535  can pass over the protrusion  512 , eliminating a 90 degree turn into the channel  508 , that could crumple or buckle the flexible connector  535 . 
       FIG. 12C  shows the device  500  in an assembled state where the cover assembly is fixed to the housing  501 , for example, by an adhesive positioned along a periphery thereof. In some examples, the cover assembly  530  can be disposed on and at least partially supported by the housing  501  or components of the device  500  prior to being affixed thereto. In this position, a gap or a space  536  can exist between a periphery of the cover assembly  530  and the housing  501 . In some examples, this gap  536  can have a width of less than about 1 mm, or less than about 0.5 mm, for example, about 0.2 mm. 
     In some examples, a reworkable adhesive  540  can be inserted through the gap  536  to a space into the internal volume  506  whereupon it can adhere or fix the cover assembly  530  to the housing  501 , and provide a substantially air or water tight dust seal for the internal volume. In some examples, this adhesive  540  can be a reworkable pressure sensitive adhesive, such as a reactive hot melt pressure sensitive adhesive. Further, the adhesive  540  can be applied or inserted through the gap  536  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 assembly  530  to the housing  501 . In some examples, the adhesive  540  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  540  can include polyurethane. The adhesive  540  can adhere to the materials of the cover assembly  530  and housing  501 , including metals such as aluminum or stainless steel, ceramics such as glass, and plastics. 
     Further, due to the reworkable nature of the adhesive  540 , the adhesive  540  can be reheated and removed as a substantially unitary component from the device  500  through the gap  536  if disassembly of the device  500  is desired, for example, to facilitate repair or recycling of one or more components of the device  500 . Accordingly, in some examples, the temperature range to release the reworkable adhesive  540  can be greater than a temperature of the adhesive location during regular operation of the device  500 , but less than a temperature that would damage the components adjacent to the adhesive  540 . In some examples, the adhesive  540  can be substantially chemically or environmentally inert, can be opaque or non-transparent, and can have a color, such as matte black. Various methods for assembling electronic devices, including components having various features in various arrangements, are detailed below, with reference to  FIGS. 13-14 . 
       FIG. 13  shows a process flow diagram of an exemplary process for forming or assembling an electronic device, as described herein. The process  600  for assembling the device can include inserting a display component into an internal volume at least partially defined by a housing including a lip extending from a sidewall, at block  610 , and sliding the display component in the internal volume to position a portion of the display component under the lip, at block  620 , to engage a retention feature of the display component with an engagement feature affixed to the housing, and positioning a securing component in the internal volume between the display component and a sidewall of the housing, at block  630 . 
     At block  610 , a display component, such as a backlight unit as described herein, can be inserted into an internal volume at least partially defined by a housing that includes a lip extending from a sidewall, for example, housing  501  described above. As described with respect to  FIGS. 10A-10C , the display component can be inserted, dropped, raised, translated, angularly rotated, or any combination thereof until it rests in the internal volume defined by the housing. In some examples, inserting the display component into the housing can also pass a portion of an engagement feature or features into one or more first orifices of the corresponding retention features of the display component, as described herein. 
     At block  620 , the display component can be slid or translated in the internal volume relative to the housing to position at least a portion of the display component under the lip of the housing, for example, as illustrated in  FIGS. 10B and 10C . This translation can also translate one or more retention features of the display component relative to one or more corresponding engagement features affixed to the housing to engage a retention feature of the display component with an engagement feature, for example, as illustrated in  FIGS. 9B-9D and 10B-10C . In some examples, the sliding or translation of the display component relative to the housing can be achieved by inserting one or more tools between the display component and housing and exerting a force on the display component. In some examples, the tool or tools can be metal and can include steel. In some examples, a cam can be positioned in the internal volume and the cam can be rotated to exert a force on the display component and move the display component relative to the housing. 
     At block  630  a securing component or components can be positioned in the internal volume between the display component and the housing, for example, in a space or a location between the display component and the housing that is formed due to the lateral translation of block  620 . In some examples, the securing component can include a shaft or a pin and a shim, for example, as described with respect to  FIG. 10C . 
       FIG. 14  shows a process flow diagram of an exemplary process for forming or assembling an electronic device, as described herein. The process  700  for assembling the device can include passing a portion of a cover assembly into an internal volume between a display component and the housing adjacent to a securing component, at block  710 , and fastening the cover assembly to the housing, at block  720 . In some examples, the process  700  can be carried out on a device that has been at least partially assembled by process  600 , as described herein. 
     At block  710 , a portion of a cover assembly, for example, a daughterboard, is passed into the internal space at least partially defined by the housing, between a sidewall of the housing and another component in the internal volume, such as a backlight unit, for example, as illustrated in  FIG. 12B . The cover assembly can include a cover at least partially defining an exterior surface of the electronic device and the portion, such as the daughterboard, can extend substantially perpendicularly from the cover. In some examples, passing a portion of the cover assembly into the internal volume can include extending a flexible electrical connector from the portion in a first direction into a recess defined by the housing, and further extending the flexible connector from the recess in a second direction under the display component, for example, as illustrated in  FIG. 12B . 
     At block  720 , the cover assembly is fastened to the housing, for example, by applying or disposing a reworkable adhesive between the cover assembly and the housing, as described with respect to  FIG. 12C . Upon fixing the cover assembly to the housing, the display component and the cover assembly, for example, including a transparent cover material and an LCD, are retained in or on the internal volume, and a major surface of the housing at least partially defining the exterior surface of the electronic device is free of components passing therethrough to fasten the display component or cover assembly to the housing. 
     While the present disclosure generally describes components and features and methods for their retention in an internal volume of a device, the components, features, and methods described herein can be used in any combination or order and with any component or electronic device as desired. Further, the components and features can assume any geometric shape, pattern, size, or combination of shapes, patterns, and sizes. Additionally, the engagement and retention features described herein can be positioned on or extend from any surface or surfaces of any desired housing and/or components. 
     To the extent applicable to the present technology, gathering and use of data available from various sources can be used to improve the delivery to users of invitational content or any other content that may be of interest to them. The present disclosure contemplates that in some instances, this gathered data may include personal information data that uniquely identifies or can be used to contact or locate a specific person. Such personal information data can include demographic data, location-based data, telephone numbers, email addresses, TWITTER® ID&#39;s, home addresses, data or records relating to a user&#39;s health or level of fitness (e.g., vital signs measurements, medication information, exercise information), date of birth, or any other identifying or personal information. 
     The present disclosure recognizes that the use of such personal information data, in the present technology, can be used to the benefit of users. For example, the personal information data can be used to deliver targeted content that is of greater interest to the user. Accordingly, use of such personal information data enables users to calculated control of the delivered content. Further, other uses for personal information data that benefit the user are also contemplated by the present disclosure. For instance, health and fitness data may be used to provide insights into a user&#39;s general wellness, or may be used as positive feedback to individuals using technology to pursue wellness goals. 
     The present disclosure contemplates that the entities responsible for the collection, analysis, disclosure, transfer, storage, or other use of such personal information data will comply with well-established privacy policies and/or privacy practices. In particular, such entities should implement and consistently use privacy policies and practices that are generally recognized as meeting or exceeding industry or governmental requirements for maintaining personal information data private and secure. Such policies should be easily accessible by users, and should be updated as the collection and/or use of data changes. Personal information from users should be collected for legitimate and reasonable uses of the entity and not shared or sold outside of those legitimate uses. Further, such collection/sharing should occur after receiving the informed consent of the users. 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 may be governed by federal and/or state laws, such as the Health Insurance Portability and Accountability Act (HIPAA); whereas health data in other countries may 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 may 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. 
     As used herein, the terms exterior, outer, interior, inner, top, and bottom are used for reference purposes only. An exterior or outer portion of a component can form a portion of an exterior surface of the component but may not necessarily form the entire exterior of outer surface thereof. Similarly, the interior or inner portion of a component can form or define an interior or inner portion of the component but can also form or define a portion of an exterior or outer surface of the component. A top portion of a component can be located above a bottom portion in some orientations of the component, but can also be located in line with, below, or in other spatial relationships with the bottom portion depending on the orientation of the component. 
     Various inventions have been described herein with reference to certain specific embodiments and examples. However, they will be recognized by those skilled in the art that many variations are possible without departing from the scope and spirit of the inventions disclosed herein, in that those inventions set forth in the claims below are intended to cover all variations and modifications of the inventions disclosed without departing from the spirit of the inventions. The terms “including:” and “having” come as used in the specification and claims shall have the same meaning as the term “comprising.” 
     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.
