2. The display as claimed in claim 1 , wherein the resilient layer further has an internal opening to receive a component located on a bottom side of the display circuit board.
3. The display as claimed in claim 1 , wherein the resilient layer comprises:
an upper horizontal end;
a lower horizontal end; and
a pair of vertical sides extending between the upper and lower horizontal ends.
4. The display as claimed in claim 1 , wherein:
the first surface is a permanent adhesive surface.
5. The display as claimed in claim 3 , wherein:
the second surface is disposed only along the upper and horizontal ends of the resilient layer.
6. The display as claimed in claim 3 , wherein:
the second surface is disposed only along the pair of vertical sides of the resilient layer.
7. The display as claimed in claim 3 , wherein:
the second surface is disposed only in corners of the resilient layer.
8. The display as claimed in claim 1 , further comprising:
a light guide coupled to the display panel and the display circuit board, the light guide including first and second clips for securing the display to a second circuit board of the computing device, the first and second clips being configured to allow the display to move relative to the computing device when the display panel is mounted to the handheld computing device.
9. The display as claimed in claim 8 , further comprising:
a light reflective plate located between the display circuit board and the light guide.
10. The display as claimed in claim 9 , further comprising a pair of opposed cover plates fastened to the light guide and being configured to provide electrostatic discharge (ESD) protection for the display panel and the display circuit board.
11. The display as claimed in claim 10 , wherein the display panel, the display circuit board and the light guide are disposed between the cover plates.
12. The display as claimed in claim 10 , wherein the opposed cover plates include locking tabs that fasten the cover plates to the light guide.
13. The display as claimed in claim 9 , wherein the light guide includes at least one guide pin for aligning the display panel with the display circuit board of the computing device.
14. A handheld computing device comprising:
a motherboard;
a display mounted to the motherboard, the display comprising:
a display panel; and
a display circuit board carrying display electronics for the display panel; and
a resilient layer having a first surface and a second surface, the first surface being adhered to the display circuit board, the second surface adhered to the motherboard and comprising a repositional adhesive, and the resilient layer being positioned such that the resilient layer is disposed between the circuit display board and the motherboard.
15. The handheld computing device as claimed in claim 14 , wherein the resilient layer further has an internal opening to receive a component located on a bottom side of the display circuit board.
16. The handheld computing device as claimed in claim 14 ,
wherein:
the first surface is a permanent adhesive surface.
17. The handheld computing device as claimed in claim 14 , wherein:
the display further comprises
a light reflective plate located between the motherboard and the light guide; and
the handheld computing device further comprises
a light guide coupled to the display panel and the display circuit board;
the light guide including first and second clips for securing the display to a second circuit board of the handheld computing device, the first and second clips located at first and second sides of the light guide and being configured to allow the display to move relative to the motherboard.
18. The handheld computing device as claimed in claim 17 , further comprising a pair of opposed cover plates fastened to the light guide and being configured to provide electrostatic discharge (ESD) protection for the display panel and the display circuit board.
19. The handheld computing device as claimed in claim 18 , wherein the display panel, the display circuit board and the light guide are disposed between cover plates fastened to the light guide.
