Abstract

Embodiments of the invention include a LCD having a mirror including a substrate having a first surface and a second surface. The substrate may carry one or more dichroic mirror coatings and the LCD or mirror may be selectively viewable from the first surface side. Embodiments of the invention also include methods of making and using a LCD mirror.

Claims

1. A LCD comprising a mirror including a substrate having a first surface and a second surface and carrying one or more dichroic mirror coatings, the LCD or mirror being selectively viewable from the first surface side.

2. The LCD of claim 1, wherein the mirror is larger than an image created by the LCD when the LCD is switched on.

3. The LCD of claim 1, wherein the LCD is viewable when it is switched on, and the mirror is viewable when the LCD is switched off.

4. The LCD mirror claim 1, wherein the dichroic mirror coating includes a base layer and a metal oxide film layer.

5. The LCD mirror of claim 4, wherein the base layer includes silicon nitride and the metal oxide layer includes titanium oxide.

6. The LCD mirror of claim 1, wherein the dichroic mirror coating is carried on the first surface.

7. The LCD mirror of claim 1, wherein the dichroic mirror coating is carried on the second surface.

8. The LCD mirror of claim 1, wherein the dichroic mirror coating includes a reflection enhancing coating.

9. The LCD mirror of claim 8, wherein the reflection enhancing coating includes niobium and titanium.

10. The LCD mirror of claim 1, further including a protective overcoat.

11. The LCD mirror of claim 10, wherein the protective overcoat includes silicon.

12. The LCD mirror of claim 1, wherein one or more functional coatings is carried on the first surface.

13. The LCD mirror of claim 12, wherein the one or more functional coatings exhibits self-cleaning properties.

14. The LCD mirror of claim 13, wherein the functional coating comprises silica.

15. The LCD mirror of claim 12, wherein the one or more functional coatings includes a photocatalytic coating.

16. The LCD mirror of claim 15, wherein the photocatalytic coating comprises titanium oxide.

17. The LCD mirror of claim 1, wherein the LCD is able to display television images.

18. The LCD mirror of claim 17, wherein the LCD is able to display color images.

19. The LCD mirror of claim 1, further comprising one or more dichroic coatings and one or more functional coatings applied to the substrate with sputter up/sputter down techniques.

20. A LCD comprising a mirror including a substrate having a first surface and a second surface and carrying one or more dichroic mirror coatings including a base layer and a metal oxide film layer and one or more functional coatings, the LCD or mirror being selectively viewable from the first surface side.

21. The LCD mirror of claim 20, wherein the base layer includes silicon nitride and the metal oxide layer includes titanium oxide.

22. The LCD mirror of claim 20, wherein the one or more functional coatings exhibits self-cleaning properties.

23. The LCD mirror of claim 22, wherein the functional coating comprises silica.

24. The LCD mirror of claim 20, wherein the one or more functional coatings includes a photocatalytic coating.

25. The LCD mirror of claim 24, wherein the photocatalytic coating comprises titanium oxide.

26. A method of making a LCD mirror comprising providing a dual direction sputtering apparatus and a substrate, sputtering a functional coating onto a first side of the substrate from a first direction, sputtering a dichroic mirror coating onto a second side of the substrate from a second direction, and functionally connecting a LCD to the second side of the substrate.

27. The method of claim 26, wherein the dichroic mirror coating includes a base layer and a metal oxide film layer.

28. The method of claim 27, wherein the base layer includes silicon nitride and the metal oxide layer includes titanium oxide.

29. The method of claim 26, wherein the dichroic mirror coating is sputtered on the first surface.

30. The method of claim 26, wherein the dichroic mirror coating is sputtered on the second surface.

31. The method of claim 26, wherein the dichroic mirror coating includes a reflection enhancing coating.

32. The method of claim 31, wherein the reflection enhancing coating includes niobium and titanium.

33. The method of claim 26, further including a protective overcoat.

34. The method of claim 33, wherein the protective overcoat includes silicon.

35. The method of claim 26, wherein one or more functional coatings is sputtered on the first surface.

36. The method of claim 35, wherein the one or more functional coatings exhibits self-cleaning properties.

37. The method of claim 35, wherein the functional coating comprises silica.

38. The method of claim 35, wherein the one or more functional coatings includes a photocatalytic coating.

39. The method of claim 38, wherein the photocatalytic coating comprises titanium oxide.
