Abstract

A display device comprising at least two display layers at least in part overlapping in which at least one of said display layers has a dissimilar configuration to the other display layer(s) such that moiré interference is reduced.

Claims

1. A multi-component display comprising:

a first display screen comprising a first plurality of pixels, wherein said first display screen is operable to display a first image using said first plurality of pixels, and wherein a first pixel of said first plurality of pixels comprises a first plurality of sub-pixels arranged in a first pattern; and

a second display screen comprising a second plurality of pixels, wherein said second display screen is operable to display a second image using said second plurality of pixels, wherein said second display screen overlaps said first display screen, wherein a second pixel of said second plurality of pixels comprises a second plurality of sub-pixels arranged in a second pattern, wherein said second pattern is different from said first pattern, and wherein an overlap of said first plurality of sub-pixels and said second plurality of sub-pixels is configured to reduce Moiré

interference, and wherein said second pixel comprises a square boundary having edges and wherein said second pattern of said second plurality of sub-pixels of said second pixel comprises a blue sub-pixel configured in a diamond pattern with straight edges such that at least one edge of said diamond pattern is not parallel to said edges of said square boundary of said second pixel, and first and second red sub-pixels and first and second green sub-pixel occupy remaining areas of said square boundary.

2. The multi-component display of claim 1, wherein said first plurality of pixels are arranged in a first tessellated pixel pattern, and wherein said second plurality of pixels are arranged in a second tessellated pixel pattern.

3. The multi-component display of claim 1, wherein said first plurality of pixels are arranged in a third pattern, and wherein said second plurality of pixels are arranged in a fourth pattern.

4. The multi-component display of claim 1, wherein said first display screen is selected from a group consisting of a liquid crystal display, a light emitting diode display, an organic light emitting diode display and a projection display device.

5. The multi-component display of claim 1, wherein said second display screen is selected from a group consisting of a liquid crystal display, a light emitting diode display, an organic light emitting diode display and a projection display device.

6. The multi-component display of claim 1 further comprising:

at least one interstitial layer disposed between said first and second display screens.

7. The multi-component display of claim 6, wherein said at least one interstitial layer comprises a diffuser.

8. The multi-component display of claim 1 further comprising:

a component operable to generate light to illuminate said first image and said second image.

9. The multi-component display of claim 1, wherein a first pixel of said first plurality of pixels has a first shape, and wherein a second pixel of said second plurality of pixels has a second shape.

10. The multi-component display of claim 1, wherein a first pixel of said first plurality of pixels has a border with a first curvature, and wherein a second pixel of said second plurality of pixels has a border with a second curvature.

11. The multi-component display of claim 1, wherein a first sub-pixel of said first plurality of sub-pixels has a first shape, and wherein a second sub-pixel of said second plurality of sub-pixels has a second shape.

12. The multi-component display of claim 1, wherein a first sub-pixel of said first plurality of sub-pixels has a border with a first curvature, and wherein a second sub-pixel of said second plurality of sub-pixels has a border with a second curvature.

13. The multi-component display of claim 1, wherein said first plurality of pixels comprises a first plurality of color filters arranged in a first pattern, and wherein said second plurality of pixels comprises a second plurality of color filters arranged in a second pattern.

14. A multi-component display comprising:

a first display screen comprising a first plurality of pixels, wherein said first display screen is operable to display a first image using said first plurality of pixels, wherein said first display screen utilizes a first display technology, and wherein said first display screen comprises a first black matrix pattern; and

a second display screen comprising a second plurality of pixels, wherein said second display screen is operable to display a second image using said second plurality of pixels, wherein said second display screen overlaps said first display screen, wherein said second display screen comprises a second black matrix pattern that is different from said first black matrix pattern, wherein said second display screen utilizes a second display technology, and wherein said second display technology is different from said first display technology, and wherein said overlap is configured to reduce Moiré

interference.

15. The multi-component display of claim 14, wherein said first plurality of pixels are arranged in a first tessellated pixel pattern, and wherein said second plurality of pixels are arranged in a second tessellated pixel pattern.

16. The multi-component display of claim 14, wherein said first plurality of pixels are arranged in a first pattern, and wherein said second plurality of pixels are arranged in a second pattern.

17. The multi-component display of claim 14, wherein said first display technology is selected from a group consisting of a liquid crystal display, a light emitting diode display, an organic light emitting diode display and a projection display device.

18. The multi-component display of claim 14, wherein said second display technology is selected from a group consisting of a liquid crystal display, a light emitting diode display, an organic light emitting diode display and a projection display device.

19. The multi-component display of claim 14 further comprising:

at least one interstitial layer disposed between said first and second display screens.

20. The multi-component display of claim 19, wherein said at least one interstitial layer comprises a diffuser.

21. The multi-component display of claim 14 further comprising:

a component operable to generate light to illuminate said first image and said second image.

22. The multi-component display of claim 14, wherein a first pixel of said first plurality of pixels has a first shape, and wherein a second pixel of said second plurality of pixels has a second shape.

23. The multi-component display of claim 14, wherein a first pixel of said first plurality of pixels has a border with a first curvature, and wherein a second pixel of said second plurality of pixels has a border with a second curvature.

24. The multi-component display of claim 14, wherein said first plurality of pixels comprises a first plurality of sub-pixels, and wherein said second plurality of pixels comprises a second plurality of sub-pixels.

25. The multi-component display of claim 24, wherein a first sub-pixel of said first plurality of sub-pixels has a first shape, and wherein a second sub-pixel of said second plurality of sub-pixels has a second shape.

26. The multi-component display of claim 24, wherein a first sub-pixel of said first plurality of sub-pixels has a border with a first curvature, and wherein a second sub-pixel of said second plurality of sub-pixels has a border with a second curvature.
