A display device may include a bezel to provide protection from various forces, such as user handling. The bezel may also be expected to provide the device with a pleasing appearance and form factor that does not interfere with a user's experience.
This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter. Furthermore, the claimed subject matter is not limited to implementations that solve any or all disadvantages noted in any part of this disclosure.
Examples are disclosed that relate to display devices and mounting brackets for securing a bezel to a display device. In one example, a display device comprises a display unit and a bezel comprising at least one pocket. The display device comprises a mounting bracket comprising a display unit attachment portion affixed to the display unit and at least one tongue that extends at least partially into the at least one pocket. An adhesive binds the at least one tongue to at least one surface of the at least one pocket, thereby coupling the bezel to the display unit via the mounting bracket.
Another example provides a mounting bracket for securing a bezel to a display unit of a display device. The mounting bracket comprises a display unit attachment portion comprising a planar face configured to be affixed to the display unit, and at least one tongue configured to be affixed to an inner sidewall of the bezel. The at least one tongue comprises a planar surface that is angled with respect to the planar face of the display unit attachment portion.
Another example provides a method for assembling a display device. The method comprises positioning a bezel relative to a display unit, the bezel comprising at least one pocket. The method further comprises dispensing an adhesive into the at least one pocket, and providing a mounting bracket comprising a display unit attachment portion configured to be affixed to the display unit, and at least one tongue configured to extend at least partially into the at least one pocket. The tongue is positioned at least partially within the at least one pocket and the adhesive, and the display unit attachment portion is affixed to the display unit.
A display device may include a bezel to provide protection from various forces, such as user handling. The bezel may surround and protect various components of the device, such as an internal display unit. The bezel may also be expected to provide the device with a pleasing appearance and a form factor that does not obstruct or otherwise interfere with a user's experience and interactions with the display device.
In some examples, components of a display device may have dimensions or shapes that vary from one unit to the next. For example, manufacturing variations may result in a display surface with minor differences in length, width, and/or thickness. Similarly, the thickness of a device's touch display module or particular components of the module may vary.
To accommodate such variations, in some examples a bezel may be configured to wrap around the display surface while leaving a gap between itself and the display surface. In this manner, the bezel may provide the device with mechanical protection, and the gap may accommodate some degree of variation in the dimensions and/or the shapes of the components. For example, a slightly thicker display surface may still fit within tolerances provided by the gap.
However, such gaps may create a less pleasing appearance and/or undesirably increase the form factor of the device. Further, wrapping the bezel around a front surface of the display may interfere with the user's interactions and use of the device. For example, portions of the bezel wrapped around the front surface may reduce an active area of the display, and may block portions of the area in which images are displayed and in which touch-screen devices may receive user input. In large or heavy display devices, such as all-in-one computing devices and smart whiteboards, a larger bezel may be utilized to support additional components. Especially in these examples, the larger and more prominent bezel can interfere with user interactions and further reduce the active area of the display.
In some examples of display devices, the bezel can physically interfere with the user providing touch gestures to a touch-sensitive screen. For example, when the bezel is wrapped around the front of the display, the user's finger may hit the bezel when performing a touch gesture. In other examples, two or more touch-sensitive display devices may be arranged adjacent to one another in a tiled configuration. The displays may be integrated via a shared user interface to enable a user to provide a continuous touch input that spans across the display devices. In these examples, where each display includes a bezel that wraps around the front display surface, the protruding bezels create a physical barrier between adjacent display surfaces. Accordingly, when a user performs a touch gesture that spans across two displays, the user's finger or stylus is physically interrupted by the protruding bezels.
In some examples, it may be desirable to affix the bezel behind the display surface. In this manner, the physical barrier between tiled devices may be avoided. However, it may be difficult to affix the bezel to both the display surface and another structural component of the device, and to properly position and align the bezel, display surface and other components, without introducing potentially damaging internal stresses. Additionally, these configurations may not allow three-dimensional adjustments to the relative positions of the bezel, display surface and internal components that may be necessary to achieve uniform spacings and gaps, and to account for variations in component dimensions and locations, such as display glass to bezel spacings and different display module sizes. Thus, in some display devices that affix the bezel behind the display surface, when component dimensions vary from unit to unit, the assembly processes that affix the bezel to the display surface and to other structural components of the device can introduce potentially harmful component stresses, and may struggle to produce consistent and uniform tolerances and component alignments.
Accordingly, and as described in more detail below, the present disclosure is directed to display devices, mounting brackets and methods for assembling display devices that may address one or more of the above-described issues. With reference now to
In the example of
As described in more detail below, each display device may utilize a plurality of mounting brackets that couple a bezel to a display unit, such as a touch display module or a backlight unit. In one potential advantage of the present disclosure, the mounting brackets couple the bezel to the display unit in a manner that enables three-dimensional positioning of the bezel relative to the display unit to meet tolerance and alignment requirements in all three x, y and z directions. In this manner, the bezel may be securely affixed to the display unit while also allowing for variations in the length, width and height of the display unit and variations in the display surface (glass) length, width and thickness. Additionally, the disclosed bezel and mounting bracket configurations enable such secure coupling and the performance of adjustments to accommodate such variations without introducing internal loads or stresses that may compromise structural integrity or otherwise damage components. Further, the disclosed bezel and mounting bracket configurations enable the bezel to be attached to the backside of the display surface, thereby avoiding bezel components protruding above the display surface.
With reference now to
As described in more detail below, the bezel 108 comprises at least one pocket configured to receive a portion of the side mounting bracket 212. The side mounting bracket 212 comprises at least one tongue that corresponds to the pocket in the bezel 108. In the example shown in
As shown in
The tolerance and room for movement of the side mounting bracket 212 that is provided by the tongues 220, 224 and pockets 216, 228 enable the bezel 108 to be properly aligned and securely mounted to both a surface of the display and to the display unit 204. With reference now to
Further, and with continued reference to
As noted above, the bezel 108 may be affixed to the underside 240 of the display surface 236 via an adhesive 244, such as a sheet of pressure-sensitive-adhesive (PSA) between the display surface 236 and the front face 232 of the bezel. The adhesive 244 may be applied to the front face 232 of the bezel 108 or to the display surface 236 prior to positioning the bezel 108 relative to the display unit 204. For example, the display device 104 may be assembled by first applying the adhesive 244 to the display surface 236, then aligning the bezel 108 relative to the display unit 204 and bonding the bezel to the display surface via the adhesive.
With continued reference to
In some examples, an adhesive 260 may be dispensed into the first pocket 216 prior to installing the side mounting bracket 212. As illustrated by the dashed line in
It will be appreciated that any suitable adhesive may be utilized in the pocket 216. For example, the adhesive may comprise a hot-melt adhesive or a multi-component adhesive, such as a two-part epoxy. In some examples where the adhesive is dispensed into the pocket prior to installing a side mounting bracket, the adhesive may comprise a high-viscosity adhesive. In this manner, the adhesive 260 may permit installation of the first tongue 220 into the first pocket 216 while the adhesive is still malleable. In some examples, when the first tongue 220 is pressed through the adhesive 260, the adhesive 260 may part and wick up to one or more sides of the tongue 220. In other examples where the adhesive is dispensed into a pocket after installing the side mounting bracket, a lower-viscosity adhesive may be utilized. Accordingly, and in one potential advantage of the present disclosure, utilizing an adhesive with the tongue and pocket configuration described above enables the side mounting bracket 212 to be moved and positioned in all three x, y and z directions, and the bracket to be affixed to display unit 204, before the adhesive fully cures or solidifies to create a solid joint. For example, the adhesive 260 may be cured via ultraviolet light, air, moisture, combinations of the foregoing, or any other suitable mechanism after the mounting bracket 212 is installed.
For example, as described above, the first pocket 216 provides tolerance for the first tongue 220 and side mounting bracket 212 to translate and rotate in three dimensions while at least a portion of the first tongue is positioned in the pocket 216. In the example illustrated in
With reference again to
With reference now to
As noted above, the side mounting bracket 212 may be affixed to the display unit 204 via screw 268 before the adhesive in pockets 216 and 228 fully cures or solidifies. Accordingly, and in one potential advantage of the present disclosure, the freedom of movement of the tongues 220, 224 in pockets 216, 228 enables the side mounting bracket 212 to be affixed to the display unit 204 without creating internal component stresses from the applied forces, such as torque from tightening the screw 268. In this manner, the side mounting bracket 212 may float within the tolerances provided by the tongues 220, 224 and pockets 216, 228 to change position and/or orientation, rather than absorbing and transmitting such forces. Further, the tolerances provided by this configuration allow for minor differences in the position and/or orientation of the bezel 108 relative to the display unit 204, thereby compensating for variation among the components of the display device 104.
As illustrated in
As noted above, in some examples a display device may include a plurality of side mounting brackets 212 to secure a bezel or multiple sections of a bezel to a display unit. In one example, such as in the display device 104 described above, the bezel 108 may be mounted to the display device by 36 side mounting brackets located around the perimeter of the device. Each side mounting bracket of the plurality of brackets is secured to corresponding pockets in the bezel as described above. In other examples, any suitable number of side mounting brackets may be utilized.
In some examples, in addition to or instead of using side mounting brackets 212, a display device may utilize one or more mounting brackets having a different configuration. For example and with reference now to
With reference to
In some examples, the downwardly-projecting tongue 632 may comprise a curved portion that extends around the corner 624 of the corner mounting bracket 616. The bezel 108 may include a similarly-curved corner pocket 640 at the corner 620 of the bezel. The curved portion of the tongue 632 may be positioned within in the corner pocket 640 in a manner similar to the downwardly-extending portion of the tongue within the side pocket 636. Adhesive in the corner pocket 640 (not shown) binds the curved portion of the tongue 632 to interior surface(s) of the pocket to further couple the bezel 108 to the display unit via the corner mounting bracket. In this manner, the corner mounting bracket 616 may provide additional support in the corner 620 of the bezel 108.
It will also be appreciated that the bezel 108 may comprise any suitable arrangement of pockets, such as one or more side pockets 636, one or more corner pockets 640, various combinations of side and corner pockets, as well as first and second pockets 216, 228 for side mounting brackets 212 as described above.
In some examples, the bezel 108 may comprise one or more different sections that may be interconnected to form the complete bezel. For example, the bezel 108 of the display device 104 described herein may comprise four independent sections that are connected as described below.
As illustrated in
The corner mounting bracket 616 is affixed to the display unit 204 via one or more display unit attachment portions of the bracket. In this example, two screws 668 extend through two apertures in display unit attachment portions 658 and into corresponding apertures in the display unit 204. In some examples, the bezel attachment portion 656 of the corner mounting bracket 616 may be affixed to the boss 652 after affixing the corner mounting bracket 616 to the display unit 204 as described above. For example, torque applied while tightening screws 668 may result the corner mounting bracket 616 changing position and/or orientation, in a manner similar to that described above regarding the side mounting brackets 212.
As described in more detail below, the bezel attachment portion 656 and the boss 652 may be configured to contact and move relative to each other prior to tightening the screw 660. In one example, the bezel 108 may be positioned and the corner mounting bracket 616 affixed to the display unit 204, after which the bracket is then secured to the boss 652 of the bezel 108 via the bezel attachment portion 656. In this manner, utilizing this configuration may avoid the generation of internal stress in components of the display device.
Further, the configuration of the tongue 632 and the pockets 636, 640 may provide tolerances for the corner mounting bracket 616 to move at least in an X-Y plane. In some examples, independent motion of the second section 648 of the bezel 108 may provide additional tolerance.
To provide additional freedom of movement along the z-axis, the bezel attachment portion 656 may be angled relative to an inner sidewall 672 of the second section 648 of the bezel 108. In this example, the bezel attachment portion 656 comprises a contacting face 670 that is angled relative to an inner sidewall 672 of the second section 648 when the corner mounting bracket 616 is installed (see also
To accommodate relative movement between the bezel attachment portion 656 and the boss 652, the bezel attachment portion 656 may comprise a screw slot 680 that is larger than the shank of the screw 660 in at least one dimension. In the example illustrated in
With reference again to
To assemble such a display device, in some examples all four bezel sections may be aligned at once by machinery using suitable alignment sensors. With reference now to
The gap 688 may be measured during manufacturing, and those measurements used to select an appropriately sized bumper 692 to position between the first section 644 and the second section 648 of the bezel 108. As shown in the example of
In some examples, affixing a bumper to both bezel sections when the two sections are misaligned could produce an undesirable and noticeable tilt in the bumper. Accordingly, and with reference to
For example,
In a similar manner, the second projection 696 is received and retained in a slot 699 formed in the second section 648. The bumper 692 also comprises a flat end surface 698 facing the end face 700 of the first section 644 of the bezel 108. With this configuration, the bumper 692 is securely affixed to the second section 648 of the bezel 108, and also may move freely against the end face 700 of the first section 644 of the bezel. In this manner, the bumper 692 may present a consistent and pleasing appearance of the bezel when installed, and may avoid becoming tilted or otherwise askew when the two sections of the bezel 108 are misaligned.
With reference now to
In this example, the first tongue 1112 is affixed to the inner lip 1116 by a screw 1120. A second tongue 1124 extends from an opposite side of the mounting bracket 1104 from first tongue 1112. The second tongue 1124 is also affixed to the inner lip 1116 of the bezel 1108 by a screw 1126.
Further, and like the side mounting bracket 212 in the example of
In some examples, the first and second tongues 1112, 1124 of the side mounting bracket 1104 may be affixed to the bezel 1108 after affixing the side mounting bracket 1104 to the display unit as described above. Further and like the side mounting bracket 212 described above, the tongues 1112, 1124 and the inner lip 1116 of the bezel 1108 may be configured to contact and move relative to each other prior to affixing the side mounting bracket 1104 to the display unit. Utilizing this configuration may avoid the generation of internal stress in components of the display device.
To accommodate such movement between the tongues 1112, 1124 and the inner lip 1116, each of the tongues may comprise a screw slot 1136, 1138 having a diameter that is larger than a shank of the corresponding screw 1120, 1126. Accordingly, each screw 1120, 1126 may be fastened in a variety of positions within the corresponding screw slot 1136, 1138, thereby providing tolerance for changes in the position and orientation of the side mounting bracket 1104 relative to the bezel 1108. In this manner, the angled inner lip 1116 combined with this fastener configuration enables three-dimensional positioning of the bezel relative to the display unit in all three x, y and z directions.
