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 pixel array architecture of a display, the pixel array architecture comprising a matrix of subpixels grouped into pixels, the matrix of subpixels arranged in a substantially square matrix oriented at substantially a 45 degree angle relative to a horizontal direction of the display, wherein the subpixels are arranged into pixels, and the pixels arranged into rows and columns, each pixel having three subpixels forming a right angle shape oriented in one of a first direction and a second direction opposite from the first direction.

2. The pixel array architecture of claim 1, wherein the pixels are arranged one atop each other in columns such that alternating columns comprise pixels having three subpixels forming right angle shapes oriented in opposite directions.

3. The pixel array architecture of claim 2 wherein each subpixel is shaped in the form of a square oriented at one of 0 degrees and 45 degrees from the horizontal direction of the display, and wherein each pixel comprises a green subpixel, a blue subpixel, and a red subpixel.

4. A pixel array architecture of a display, the pixel array architecture comprising a matrix of subpixels grouped into pixels, the matrix of subpixels arranged in a substantially square matrix oriented at substantially a 45 degree angle relative to a horizontal direction of the display, wherein the subpixels are arranged into pixels, and the pixels arranged into rows and columns, each pixel having three subpixels and formed into an “

I”

shape slanted at 45 degrees relative to the horizontal direction, and wherein the pixels are arranged in columns in a repeating pattern, in groups of two, one atop each other and overlapping only by two subpixels, with a vertical gap of a single subpixel in height between groups, the gap including a subpixel of a pixel of each neighboring column.

5. The pixel array architecture of claim 4 wherein each subpixel is shaped in the form of a square oriented at one of 0 degrees and 45 degrees from the horizontal direction of the display, and wherein each pixel comprises a green subpixel, a blue subpixel, and a red subpixel.

6. A pixel array architecture of a display, the pixel array architecture comprising a matrix of subpixels grouped into pixels, the matrix of subpixels arranged in a substantially square matrix oriented at substantially a 45 degree angle relative to a horizontal direction of the display, wherein the subpixels are arranged into pixels, and the pixels arranged into rows and columns, each pixel having three subpixels and formed into “

I”

shapes slanted in one of a positive 45 degree slope and a negative 45 degree slope.

7. The pixel array architecture of claim 6, wherein the pixels are arranged in columns in a repeating pattern, one atop each other, alternating in slant form negative 45 degrees to positive 45 degrees, overlapping only by two subpixels, forming a snaking vertical pattern identical in geometry to a pattern of adjacent columns.

8. The pixel array architecture of claim 7 wherein each subpixel is shaped in the form of a square oriented at one of 0 degrees and 45 degrees from the horizontal direction of the display, and wherein each pixel comprises a green subpixel, a blue subpixel, and a red subpixel.

9. The pixel array architecture of claim 6, wherein the pixels are arranged in columns in a repeating pattern, one atop each other, alternating in slant form negative 45 degrees to positive 45 degrees, overlapping only by two subpixels, forming a snaking vertical pattern, wherein for one of the odd or even columns, each upper pixel sits atop a pixel below it on a longest side of the pixel below, wherein for the other of the odd or even columns an upper pixel sits atop a pixel below it on a shortest side of the pixel below.

10. The pixel array architecture of claim 9, wherein each subpixel is shaped in the form of a square oriented at one of 0 degrees and 45 degrees from the horizontal direction of the display, and wherein each pixel comprises a green subpixel, a blue subpixel, and a red subpixel.

11. A pixel array architecture of a display, the pixel array architecture comprising a matrix of subpixels grouped into pixels, the matrix of subpixels arranged in a substantially square matrix oriented at substantially a 45 degree angle relative to a horizontal direction of the display, wherein the subpixels are arranged into pixels, and the pixels arranged into rows and columns, 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.

12. The pixel array architecture of claim 11, wherein the pixels are arranged in columns in a repeating pattern, one atop each other, overlapping only by two subpixels, forming a snaking vertical pattern identical in geometry to a pattern of adjacent columns, the leftmost and rightmost pixel of each pixel being shared with its respective left and right neighbor pixel.

13. The pixel array architecture of claim 12 wherein the first and second unshared subpixels are a green and a white subpixel and wherein the third and fourth shared subpixels are a red and a blue subpixel.

14. A pixel array architecture of a display, the pixel array architecture comprising a matrix of subpixels grouped into pixels arranged in rows and columns, the matrix of subpixels arranged based on a rectilinear matrix oriented at 45 degrees relative to a horizontal direction of the display, subsequently skewed to vertically align subpixels in every third subpixel row, exhibiting a reduced pixel pitch for the subpixels.
