Abstract

What is disclosed is a pixel array architecture for displays being based on a matrix of subpixels arranged in a rectilinear matrix oriented at an angle relative to a horizontal direction of the display, exhibiting a reduced pixel pitch for the subpixels.

Claims

1. A display device comprising a matrix of subpixels grouped into pixels, the matrix of subpixels arranged in a substantially rectilinear matrix oriented at substantially a 45 degree angle relative to a major axis of the display, each pixel forming a right angle shape oriented in one of a first direction and a second direction opposite from the first direction.

2. The display device of claim 1, wherein the pixels are arranged in rows and columns such that alternating columns comprise pixels having subpixels forming right angle shapes oriented in opposite directions.

3. The display device of claim 1, wherein the pixels are arranged in rows and columns such that adjacent pixels in each column comprise pixels having subpixels forming right angle shapes oriented in opposite directions.

4. The display device of claim 2 wherein each subpixel is shaped substantially in the form of a square oriented at one of 0 degrees and 45 degrees from an axis of the rectilinear matrix of subpixels.

5. The display device of claim 2 wherein each pixel comprises three subpixels.

6. The display device of claim 1 wherein each pixel comprises three subpixels.

7. A display device comprising a matrix of subpixels grouped into pixels, the matrix of subpixels arranged in a substantially rectilinear matrix oriented at substantially a 45 degree angle relative to a major axis of the display, each pixel and formed into an “

I”

shape slanted at 45 degrees relative to the major axis of the display, each pixel having a length unequal to a width of the pixel.

8. This display device of claim 7, wherein the pixels are arranged in a repeating pattern along a first direction, in groups of two pixels adjacent one another in the first direction and overlapping only by two subpixels, with a gap in said first direction of a single subpixel between groups, the gap including a subpixel of neighboring pixels adjacent the gap in directions perpendicular to the first direction.

9. The display device of claim 8 wherein each subpixel is shaped substantially in the form of a square oriented at one of 0 degrees and 45 degrees from an axis of the rectilinear matrix of subpixels.

10. A display device comprising a matrix of subpixels grouped into pixels, the matrix of subpixels arranged in a substantially rectilinear matrix oriented at substantially a 45 degree angle relative to a major axis of the display, said pixels comprising pixels formed into “

I”

shapes slanted at a positive 45 degree slope relative to a major axis of the display and pixels formed into “

I”

shapes slanted at a negative 45 degree slope relative to the major axis of the display.

11. The display device of claim 10, wherein the pixels are arranged in extended repeating patterns, the pixels adjacent each other along a length of each extended repeating pattern alternating in slant from negative 45 degrees to positive 45 degrees, overlapping only by two subpixels, and forming a snaking pattern along the length of the extended repeating pattern identical in geometry to a pattern of adjacent extended repeating patterns.

12. The display device of claim 11, wherein each subpixel is shaped substantially in the form of a square oriented at one of 0 degrees and 45 degrees from an axis of the rectilinear matrix of subpixels.

13. The display device of claim 11, wherein each pixel comprises three subpixels.

14. The display device of claim 10, wherein the pixels are arranged in extended repeating patterns, the pixels adjacent each other along a length of each extended repeating pattern alternating in slant from negative 45 degrees to positive 45 degrees, overlapping only by two subpixels, and forming a snaking pattern along the length of the extended repeating pattern, wherein for one of each pair of adjacent extended repeating patterns, each pixel meets an adjacent pixel in a first direction within the extended repeating pattern on a longest side of the adjacent pixel, and wherein for the other of each pair of adjacent extended repeating patterns, each pixel meets an adjacent pixel in the first direction within the extended repeating pattern on a shortest side of the adjacent pixel.

15. The display device architecture of claim 14, wherein each subpixel is shaped substantially in the form of a square oriented at one of 0 degrees and 45 degrees from an axis of the rectilinear matrix of subpixels.

16. The display device of claim 14, wherein each pixel comprises three subpixels.

17. A display device comprising a matrix of subpixels grouped into pixels, the matrix of subpixels arranged in a substantially rectilinear matrix oriented at substantially a 45 degree angle relative to a major axis of the display, each pixel having four subpixels and formed into a diamond shape, a first and a second of the four subpixels unshared with neighboring pixels, a third and a fourth subpixel of the four subpixels shared with neighboring pixels.

18. The display device of claim 17, wherein the pixels are arranged in extended repeating patterns, the pixels adjacent each other along a length of each extended repeating pattern overlapping only by two subpixels, forming a snaking pattern the length of the extended repeating pattern identical in geometry to a pattern of adjacent extended repeating patterns, the two subpixels of each pixel in the extended repeating pattern which are closest to the adjacent extended repeating pattern on either side of the extended repeating pattern being shared with respective pixels of the adjacent extended repeating patterns.

19. The display device of claim 18 wherein the unshared subpixels of each pixel comprise a green subpixel and a white subpixel and wherein the shared subpixels of each pixel comprise a red subpixel and a blue subpixel.

20. A display device comprising a matrix of subpixels grouped into pixels, the matrix of subpixels arranged based on a substantially rectilinear matrix oriented at substantially a 45 degree angle relative to a major axis of the display, subsequently skewed either to vertically align subpixels in every third subpixel row or to horizontally align subpixels in every third subpixel column, exhibiting a reduced pixel pitch for the subpixels.
