Support for an Optically Bonded Display Device
Display device support techniques are described. In one or more implementations, an apparatus includes a touch panel assembly and a display housing. The touch panel assembly includes one or more touch sensors and a transparent surface. The display housing secures a display module, the display module optically bonded to the touch panel assembly. A support is disposed to contact the touch panel assembly and the display housing.
1 . An apparatus comprising:
a touch panel assembly including one or more touch sensors and a transparent surface;
a display housing that secures a display module, the display module optically bonded to the touch panel assembly; and
a support disposed to contact the touch panel assembly and the display housing.
2 . An apparatus as described in claim 1 , wherein the support is configured to reduce deflection of the touch panel assembly in response to contact made against the transparent surface.
3 . An apparatus as described in claim 1 , wherein the support is configured to reduce appearance of one or more visual artifacts by the display module cause by an application of pressure to the transparent surface.
4 . An apparatus as described in claim 1 , wherein the support is positioned to extend at least partially around a perimeter defined by a portion of the display module that is optically bonded to the touch panel assembly.
5 . An apparatus as described in claim 1 , wherein the support is formed using an adhesive.
6 . An apparatus as described in claim 1 , wherein the external enclosure is configured to support a hand-held form factor.
7 . An apparatus as described in claim 1 , wherein the display module is configured as a liquid crystal display module or organic light emitting diode (OLED) display module.
8 . An apparatus as described in claim 1 , wherein the touch panel assembly is configured to detect proximity of one or more objects.
9 . An apparatus as described in claim 1 , wherein the touch panel assembly is optically bonded to the display module such that the touch panel assembly is secured to the display module and light output by the display module is viewable through the touch panel assembly.
10 . A display device comprising:
an external enclosure forming a cavity;
a touch panel assembly secured by the external enclosure and defining a first perimeter;
a display housing that secure a display module, the display housing disposed within the cavity and the display module optically bonded to the touch panel assembly such that a gap is formed between the display module and the touch panel assembly; and
a support disposed within the gap configured to reduce deflection of the display module caused responsive to a pressure applied to the touch panel assembly.
11 . A display device as described in claim 10 , wherein the support is configured to reduce deflection of the display module to reduce appearance of visual artifacts by the display module responsive to the pressure.
12 . A display device as described in claim 10 , wherein the support is positioned to extend at least partially around a perimeter defined by a portion of the display module that is optically bonded to the touch panel assembly.
13 . A display device as described in claim 12 , wherein the gap is defined between the optical bonding of the display module and the touch panel assembly and a portion of the touch panel assembly that is supported by the external enclosure.
14 . A display device as described in claim 10 , wherein the support is formed an open-cell material, closed-cell interface material, UV-cured adhesive, epoxy, urethane, acrylic, or silicone materials.
15 . A display device comprising:
an external enclosure forming a cavity;
a touch panel assembly secured by the external enclosure to define a first perimeter;
a display housing that secure a display module, the display housing disposed within the cavity and forming a second perimeter that is disposed at least partially within the first perimeter and the display module optically bonded to the touch panel assembly thereby defining a third perimeter disposed at least partially within the second perimeter; and
a support disposed between the touch panel assembly and the display housing and between the first and third perimeters.
16 . A display device as described in claim 15 , wherein the display module is a liquid crystal display module or an organic light emitting diode (OLED) module.
17 . A display device as described in claim 15 , wherein the support is disposed adjacent to the second perimeter.
18 . A display device as described in claim 15 , wherein the touch panel assembly is optically bonded to the display module such that the touch panel assembly is secured to the display module and light output by the display module is viewable through the touch panel assembly.
19 . A display device as described in claim 15 , wherein the support is configured to reduce deflection of the display module responsive to a pressure applied to the touch panel assembly.
20 . A display device as described in claim 15 , wherein the support is configured to reduce deflection of the display module to reduce appearance of visual artifacts by the display module responsive to a pressure applied to the touch panel assembly.
