Abstract

The embodiments of the present application provide a pixel display module. The pixel display module includes: a plurality of array-distributed pixel unit groups. Each of the pixel unit groups comprises four array-distributed sub-pixels, two of the sub-pixels located on a diagonal of each of the pixel unit groups emit a same first color light, and the other two of sub-pixels located on another diagonal of each of the pixel unit groups respectively emit a second color light and a third color light. Two pixel unit groups adjacent in a first direction are staggered along a second direction, and the second direction is perpendicular to the first direction.

First claim

What is claimed is:

1. A pixel display module, comprising: a plurality of array-distributed pixel unit groups;
wherein each of the pixel unit groups comprises four array-distributed sub-pixels, two of the sub-pixels located on a diagonal of each of the pixel unit groups emit a same first color light, and the other two of sub-pixels located on another diagonal of each of the pixel unit groups respectively emit a second color light and a third color light; two pixel unit groups adjacent with each other in a first direction are staggered a certain distance along a second direction perpendicular to the first direction, and the certain distance is equal to a length of one sub-pixel along the second direction;
wherein the sub-pixels in the two pixel unit groups staggered along the second direction respectively comprise one selected sub-pixel, the two selected sub-pixels are adjacent to each other located in a same column or in a same row and emit a same color light;
wherein a color distribution of the four array-distributed sub-pixels in each of the pixel unit groups is identical.

2. The pixel display module of claim 1 , wherein the two selected sub-pixels emit the first color light.

3. The pixel display module of claim 2 , wherein the first color light is green light.

4. The pixel display module of claim 3 , wherein a shape of the pixel unit group is rectangular.

5. The pixel display module of claim 4 , wherein shapes of the four sub-pixels in the pixel unit group are square.

6. The pixel display module of claim 1 , wherein,
the first color light is green light, and the second color light and the third color light are respectively red light and blue light; or,
the first color light is blue light, and the second color light and the third color light are respectively red light and green light; or,
the first color light is red light, and the second color light and the third color light are respectively green light and blue light.

7. The pixel display module of claim 1 , wherein each of the pixel unit groups comprises a first pixel unit and a second pixel unit, the first pixel unit or the second pixel unit is composed of three sub-pixels emitting different color lights, and when the pixel unit group emits light, the first pixel unit and the second pixel unit share two of the three sub-pixels, on a diagonal of the pixel unit group and respectively emit the second color light and the third color light.

8. The pixel display module of claim 7 , wherein in each of the pixel unit groups, a distance between two of the three sub-pixels in a column direction is twice a distance between two of the sub-pixels in a row direction.

9. The pixel display module of claim 7 , wherein a display unit of the first pixel unit or the second pixel unit has a square shape when the four sub-pixels in the pixel unit group are displayed under a driving mode.

10. The pixel display module of claim 1 , wherein there is a gap between the two selected sub-pixels located in a same column or in a same row.

11. The pixel display module of claim 1 , wherein sizes of the four sub-pixels in the pixel unit group are identical.

12. The pixel display module of claim 1 , wherein a shape of the pixel unit group is square.

13. The pixel display module of claim 1 , wherein each of the four sub-pixels in the pixel unit group has a rectangle shape with four rounded corners.
