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 at least portions thereof with different respective optical transparencies that, when combined, provide 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. The display of claim 1, wherein the uniformity layer includes regions having different respective transparencies.

14. The display of claim 13, wherein the integrated antenna is disposed within an antenna layer that includes regions having different respective transparencies.

15. The display of claim 14, wherein the different respective transparencies of the uniformity layer equalize the different respective transparencies across the antenna layer thereby producing a substantially uniform transparency across the display.
