Abstract

A display having an integrated antenna with a substantially uniform transparency and/or light across the display. The display may have a uniformity layer that is an optical balance of the antenna, wherein the uniformity layer and the antenna have respective optical transparencies that provide a substantially uniform transparency across the display. The display may also have a backlight that has a surface brightness intensity corresponding to an optical inverse of the antenna, and is configured to provide a substantially uniform light across the display.

Claims

1. A display, comprising:

an integrated antenna; and

a uniformity layer that is an optical balance of the integrated antenna,

wherein the uniformity layer and the integrated antenna have respective optical transparencies providing a substantially uniform transparency across the display.

2. The display of claim 1, wherein the uniformity layer is comprised of a nonconductive material.

3. The display of claim 2, wherein the uniformity layer is comprised of Polyethylene Terephthalate (PET).

4. The display of claim 1, wherein the uniformity layer is comprised of a conductive material.

5. The display of claim 1, wherein the uniformity layer is comprised of a nonconductive substrate and dispersed particles.

6. The display of claim 5, wherein the dispersed particles are beads.

7. The display of claim 5, wherein the dispersed particles are a mesh.

8. The display of claim 5, wherein the dispersed particles are metallic.

9. The display of claim 5, wherein the dispersed particles are non-conductive.

10. The display of claim 1, wherein the uniformity layer and the integrated antenna are located in a same layer of the display.

11. The display of claim 1, wherein the uniformity layer and the integrated antenna are located in different layers of the display.

12. A wireless communication device comprising the display of claim 1.

13. A display, comprising:

an integrated antenna; and

a backlight having a surface brightness intensity corresponding to an optical balance of the integrated antenna, and the backlight being configured to provide a substantially uniform light across the display.

14. The display of claim 13, wherein the backlight is configured to provide increased light emission intensity in a region located behind the integrated antenna.

15. The display of claim 13, wherein the backlight is configured to provide decreased light intensity in a region that is an inverse of the integrated antenna.

16. The display of claim 13, wherein the backlight is comprised of an array of light emitting diodes (LEDs).

17. The display of claim 16, wherein the array of LEDs is located in a side of the display.

18. The display of claim 16, wherein the array of LEDs is located over a substantial portion of the surface area of the display.

19. The display of claim 16, wherein the LEDs are organic light emitting diodes (OLEDs).

20. The display of claim 13, wherein the backlight comprises:

a light guide plastic layer;

light emitting diodes (LEDs) located on a side of the light guide plastic layer; and

a reflector located under the light guide plastic.

21. A wireless communication device comprising the display of claim 20.

22. A method of forming a display, the method comprising:

forming an antenna within the display; and

forming a uniformity layer within the display,

wherein the uniformity layer is an optical balance of the antenna, and the uniformity layer and the antenna have respective optical transparencies providing a substantially uniform transparency across the display.

23. The method of claim 22, wherein the forming the uniformity layer comprises:

heating a nonconductive substrate to a melting state;

dispersing particles into the nonconductive substrate; and

annealing the nonconductive substrate.
