Abstract

An aspect provides a method of modifying a display including a plurality of pixels wherein each of the pixels is less than twice as tall as the pixel is wide includes modifying the display to create a plurality of modified pixels wherein each of the modified pixels is at least twice as tall as the modified pixel is wide, comprising at least one of a) masking of at least a portion of the display, b) optically shifting a perceived position of at least one row of sub-pixels of the display, and c) changing the addressing of sub-pixels of the display. Other aspects are described and claimed.

Claims

1. A method of modifying a display including a plurality of pixels wherein each of the pixels is less than twice as tall as the pixel is wide, comprising:

modifying the display to create a plurality of modified pixels wherein each of the modified pixels is at least twice as tall as the modified pixel is wide, comprising at least one of;

a) masking of at least a portion of the display;

b) optically shifting a perceived position of at least one row of sub-pixels of the display; and

c) changing the addressing of sub-pixels of the display.

2. The method of claim 1 further comprising changing the addressing of sub-pixels of the display after a) or b).

3. The method of claim 1 wherein, in the case of masking of at least a portion of the display, the method further comprises rotating the viewing orientation of the display by 90 degrees.

4. The method of claim 3 wherein each of the plurality of pixels is formed from sub-pixels of different color, wherein like-colored sub-pixels are arranged in a vertical stripe pattern.

5. The method of claim 4 wherein the sub-pixels comprise red sub-pixels, green sub-pixels and blue sub-pixels.

6. The method of claim 1 wherein each of the plurality of pixels is formed from sub-pixels of different color, wherein like-colored sub-pixels are arranged in a vertical stripe pattern.

7. The method of claim 6 wherein the sub-pixels comprise red sub-pixels, green sub-pixels and blue sub-pixels.

8. The method of claim 1 wherein the perceived position of at least one row of sub-pixels of the display is optically shifted by overlaying a prism strip over the at least one row.

9. The method of claim 1 wherein the perceived position of a plurality of rows of sub-pixels of the display is optically shifted by overlaying a prism strip over more than one of the plurality of rows of sub-pixels.

10. The method of claim 1 wherein optically shifting a perceived position of the at least one row of sub-pixels of the display is combined with another optical function in a single system.

11. The display of claim 10 wherein optically shifting a perceived position of the at least one row of sub-pixels of the display is combined with view selection in a single optical film.

12. The method of claim 1 wherein a perceived position of a plurality of rows of sub-pixels of the display is optically shifted to cause a display comprising sub-pixels of different color, wherein like-colored sub-pixels are arranged in a vertical stripe pattern, to be perceived as display wherein like-colored sub-pixels are arranged in a generally diagonal pattern.

13. The method of claim 1 wherein each of the modified pixels includes two or more sub-pixels that are vertically aligned.

14. The method of claim 1 wherein the modified display provides two or more views, each of views comprising one or more modified pixels.

15. The method of claim 14 further comprising providing a view selector in operative connection with the modified display that, for each of two or more viewing perspectives, makes one of the views visible.

16. The method of claim 15 wherein the view selector comprises a lenticular array, parallax barriers or a microlens array.

17. The method of claim 1 wherein each of the modified pixels comprises two or more sub-pixels that are vertically displaced from one another.

18. An autostereoscopic display comprising:

a plurality of modified pixels,

two or more views, each of which includes one or more the plurality of modified pixels; and

a view selector that, for each of two or more viewing perspectives, makes one of the views visible;

wherein each of the modified pixels is at least twice as tall as the modified pixel is wide, and wherein the modified pixels are formed by modifying a display including a plurality of pixels wherein each of the plurality of pixels is less than twice as tall as the pixel is wide to create the plurality of modified pixels, modifying the display comprising at least one of;

a) masking of at least a portion of the display;

b) optically shifting a perceived position of at least one row of sub-pixels of the display; and

c) changing the addressing of sub-pixels of the display.

19. The display of claim 18 wherein the addressing of the sub-pixels of the display is changed after a) or b).

20. The display of claim 18 wherein, in the case of masking, the viewing orientation of the display is rotate by 90 degrees.

21. The display of claim 20 wherein each of the plurality of pixels is formed from sub-pixels of different color, and wherein like-colored sub-pixels are arranged in a vertical stripe pattern.

22. The display of claim 21 wherein the sub-pixels comprise red sub-pixels, green sub-pixels and blue sub-pixels.

23. The display of claim 18 wherein each of the plurality of pixels is formed from sub-pixels of different color, wherein like-colored sub-pixels are arranged in a vertical stripe pattern.

24. The display of claim 23 wherein the sub-pixels comprise red sub-pixels, green sub-pixels and blue sub-pixels.

25. The display of claim 18 wherein the perceived position of at least one row of sub-pixels of the display is optically shifted by overlaying a prism strip over the at least one row.

26. The display of claim 18 wherein the perceived position of a plurality of rows of sub-pixels of the display is optically shifted by overlaying a prism strip over more than one of the plurality of rows of sub-pixels.

27. The display of claim 25 wherein a system for optically shifting a perceived position of the at least one row of sub-pixels of the display also performs another optical function.

28. The display of claim 25 wherein an optical film optically shifts a perceived position of the at least one row of sub-pixels of the display and also function as the view selector.

29. The display of claim 18 wherein a perceived position of a plurality of rows of sub-pixels of the display is optically shifted to cause a display comprising sub-pixels of different color, wherein like-colored sub-pixels are arranged in a vertical stripe pattern, to be perceived as display wherein like-colored sub-pixels are arranged in a generally diagonal pattern.

30. The display of claim 18 wherein each of the pixels includes two or more sub-pixels that are vertically aligned.

31. The display of claim 18 wherein the view selector comprises a lenticular array, parallax barriers or a microlens array.

32. The display of claim 18 wherein each of the modified pixels comprises two or more sub-pixels that are vertically displaced from one another.

33. A display including a plurality of pixels wherein each of the pixels is less than twice as tall as the pixel is wide and masking to create a plurality of modified pixels wherein each of the modified pixels is at least twice as tall as the modified pixel is wide.

34. A display including a plurality of pixels wherein each of the pixels is less than twice as tall as the pixel is wide, at least one optical mechanism to shift a perceived position of at least one row of sub-pixels of the display to create a plurality of modified pixels wherein each of the modified pixels is at least twice as tall as the modified pixel is wide.
