Abstract

A display for an information handling system includes a first color sub-pixel of a first color type, a second color sub-pixel of a second color type, a third color sub-pixel of a third color type, and a fourth color sub-pixel of the second color type. The first, second, third, and fourth color sub-pixels are placed horizontally adjacent to a color sub-pixel of another type in a row of the display. The first color sub-pixel is located at a first position, the second color sub-pixel is located at a second position, the third color sub-pixel is located at a third position, and the fourth color sub-pixel is located a fourth position of the row.

First claim

What is claimed is:

1. A display for an information handling system, the display comprising:
a first plurality of color sub-pixels, wherein each of the first color sub-pixels is a first color type;
a second plurality of color sub-pixels, wherein each of the second color sub-pixels is a second color type;
a third plurality of color sub-pixels, wherein each of the third color sub-pixels is a third color type, each of the first, second, and third color sub-pixels placed horizontally adjacent to another one of the first, second, and third-color sub-pixels of another color type in a row of the display, the first color sub-pixels located at a first position and a fifth position of the row, the second color sub-pixels located at a second position, fourth position, and sixth position of the row, and the third color sub-pixel located at a third position and a seventh position of the row; and
a pixel including one of the first color sub-pixels, one of the second color sub-pixels, and one of the third color sub-pixels to create a part of an image on the display, wherein a first one of the first color sub-pixels, a first one of the second color sub-pixels, and a first one of the third color sub-pixels are lit in response to the pixel being in a first location of the display to create the part of the image, wherein a second one of the first color sub-pixels, a second one of the second color sub-pixels, and the first one of the third color sub-pixels are lit in response to the pixel being shifted to a second location of the display to create image shifting of the image, wherein the display includes twice as many second color sub-pixels as compared to the first color sub-pixels, and twice as many second color sub-pixels as compared to the third color sub-pixels.

2. The display of claim 1 , wherein all of the first color sub-pixels are created using a single first manufacturing mask, all of the second color sub-pixels are created using a single second manufacturing mask, and all of the third color sub-pixels are created using a single third manufacturing mask.

3. The display of claim 1 , wherein a first half of the second color sub-pixels are in an off state and a second half of the second color sub-pixels are in an on state in response to a first location of an image on the display, and the first half of the second color sub-pixels are in the on state and the second half of the second color sub-pixels are in the off state in response to a second location of the image on the display.

4. The display of claim 1 , wherein a resolution of the display is above a threshold level, and the second color sub-pixels in the off state are not visible in response to the resolution being above the threshold level.

5. The display of claim 1 , wherein the first color type is red, the second color type is blue, and the third color type is green.

6. A display for an information handling system, the display comprising:
a first color sub-pixel of a first color type;
a second color sub-pixel of a second color type;
a third color sub-pixel of a third color type;
a fourth color sub-pixel of the second color type, each of the first, second, third, and fourth color sub-pixels are placed horizontally adjacent to another one of the first, second, third, and fourth color sub-pixels of another color type in a row of the display, the first color sub-pixel is located at a first position, the second color sub-pixel is located at a second position, the third color sub-pixel is located at a third position, and the fourth color sub-pixel is located a fourth position of the row; and
a fifth color sub-pixel of the first color type located at a fifth position of the row; and
wherein the first color sub-pixel, the second color sub-pixel, and the third color sub-pixel are lit in response to a pixel being in a first location of the display to create a part of an image, wherein the third color sub-pixel, the fourth color sub-pixel, and the fifth color sub-pixel are lit in response to the pixel being shifted to a second location of the display to create image shifting of the image.

7. The display of claim 6 , wherein the display includes twice as many color sub-pixels of the second color type as compared to color sub-pixels of the first color type, and twice as many color sub-pixels of the second color type as compared to color sub-pixels of the third color type.

8. The display of claim 6 , wherein all color sub-pixels of the first color type are created using a single first manufacturing mask, all color sub-pixels of the second color type are created using a single second manufacturing mask, and all color sub-pixels of the third color type are created using a single third manufacturing mask.

9. The display of claim 6 , wherein a resolution of the display is above a threshold level, and the color sub-pixels of the second color type in the off state are not visible in response to the resolution being above the threshold level.

10. The display of claim 6 , wherein the first color type is red, the second color type is blue, and the third color type is green.

11. A method comprising:
powering on a first color sub-pixel, a second color sub-pixel, and a third color sub-pixel in response to a pixel being in a first location of an image on a display of an information handling system, wherein the first color sub-pixel is a first color type, the second color sub-pixel is a second color type, and the third color sub-pixel is a third color type, the first, second, and third color sub-pixels are placed horizontally adjacent to a color sub-pixel of another type in a row of the display, the first color sub-pixel is located at a first position, the second color sub-pixel is located at a second position, and the third color sub-pixel is located at a third position;
powering down the first color sub-pixel and the second color sub-pixel in response to the pixel being shifted to a second location of the display to create shifting of an image; and
powering on the third color sub-pixel, a fourth color sub-pixel, and a fifth color sub-pixel in response to the pixel being shifted to the second location, wherein the fourth color sub-pixel is the second color type and the fifth color sub-pixel is the first color type, the fourth color sub-pixel is located at a fourth position of the row, and the fifth color sub-pixel is located at a fifth position of the row, wherein the display includes twice as many color sub-pixels of the second color type as compared to color sub-pixels of the first color type, and twice as many color sub-pixels of the second color type as compared to color sub-pixels of the third color type.

12. The method of claim 11 , wherein all color sub-pixels of the first color type are created using a single first manufacturing mask, all color sub-pixels of the second color type are created using a single second manufacturing mask, and all color sub-pixels of the third color type are created using a single third manufacturing mask.

13. The method of claim 11 , wherein a resolution of the display is above a threshold level, and the color sub-pixels of the second color type in the off state are not visible in response to the resolution being above the threshold level.

14. The method of claim 11 , wherein the first color type is red, the second color type is blue, and the third color type is green.
