Abstract

A display assembly and a touch sensitive assembly that includes a conductive linear polarizer.

Claims

1. A liquid crystal display comprising:

(a) a light valve that modifies the transmittance of light through said light valve; and

(b) a linear polarizer.

2. The liquid crystal display of claim 1 further comprising a backlight that provides light to said light valve.

3. The liquid crystal display of claim 1 wherein said linear polarizer includes a wire grid polarizer.

4. The liquid crystal display of claim 3 wherein said wire grid polarizer includes an array of substantially parallel conductive wires location substantially in a plane.

5. The liquid crystal display of claim 4 wherein said plane is substantially co-planar with a plane of said light valve.

6. The liquid crystal display of claim 5 wherein said parallel conductive wires have a width of generally 15 nm to generally 150 nm.

7. The liquid crystal display of claim 5 wherein said parallel conductive wires have a width of generally 25 nm to generally 75 nm.

8. The liquid crystal display of claim 5 wherein said parallel conductive wires have a width of generally 50 nm.

9. The liquid crystal display of claim 5 wherein said parallel conductive wires have a spacing between adjacent ones of generally 50 nm.

10. The liquid crystal display of claim 5 wherein said parallel conductive wires have a spacing between adjacent ones of generally 25 nm to generally 75 nm.

11. The liquid crystal display of claim 5 wherein said parallel conductive wires have a spacing between adjacent ones of generally 15 nm to 150 nm.

12. The liquid crystal display of claim 5 wherein said parallel conductive wires have a center-to-center spacing between adjacent ones of generally 100 nm.

13. The liquid crystal display of claim 5 wherein said parallel conductive wires have a center-to-center spacing between adjacent ones of generally 50 nm to 150 nm.

14. The liquid crystal display of claim 5 wherein said parallel conductive wires have a center-to-center spacing between adjacent ones of generally 100 nm to generally 225 nm.

15. The liquid crystal display of claim 5 wherein said parallel conductive wires have a center-to-center spacing between adjacent ones of generally 25 nm to 125 nm.

16. The liquid crystal display of claim 5 wherein said parallel conductive wires have a height generally 120 nm to 140 nm.

17. The liquid crystal display of claim 5 wherein said parallel conductive wires have a height generally 50 nm to 250 nm.

18. The liquid crystal display of claim 5 wherein at least one of (1) a height, (2) a center-to-center spacing, and (3) a spacing between adjacent ones is different for different regions of said display.

19. The liquid crystal display of claim 1 wherein liquid crystal display is free from including another polarizer between said linear polarizer and said light valve.
