Abstract

A reflection resistant display with a protective layer together with a polarizer. A light valve for selective presenting an image. A gap between the light valve and the protective layer.

Claims

1. A display comprising:

(a) a transparent cover plate having a back surface and a front surface, a first polarizer supported by said cover plate; and

(b) a light valve including a second polarizer, said light valve arranged proximate to said cover plate defining a gap between said first and second polarizers and controlling an intensity of light transmitted through said touch panel.

2. The display of claim 1 wherein said front surface of said light valve comprises a glare diffusing surface.

3. The display of claim 1 wherein said rear surface of said cover plate comprises a glare diffusing surface.

4. The display of claim 1 wherein said display is free from including substantially birefringent material between the polarizing material of said first polarizer and the polarizing material of said second polarizer.

5. The display of claim 1 wherein said cover plate includes glass.

6. The display of claim 1 wherein said cover plate includes material therein that inhibits said cover plate from shattering.

7. The display of claim 1 wherein said display is free from including substantially birefringent material between the polarizing material of said first polarizer and said gap.

8. The display of claim 1 wherein said display is free from including substantially birefringent material between the polarizing material of said second polarizer and said gap.

9. The display of claim 1 wherein said gap is air.

10. The display of claim 1 wherein the polarizing material of said first polarizer is supported by a substantially non-birefringent material on a first side and a substantially birefringent material on a second side of said polarizing material.

11. The display of claim 1 wherein the polarizing material of said first polarizer is supported by a substantially non-birefringent material on a first side and a substantially non-birefringent material on a second side of said polarizing material.
