Abstract

A pixel array includes a plurality of pixel units repeatedly arranged along a row direction and a column direction, wherein each of the pixel units includes two first sub pixels, a second sub pixel and a third sub pixel, wherein the second sub pixel and the third sub pixel are disposed in adjacent two sub pixel rows, and the two first sub pixels are disposed in adjacent two sub pixel rows, such that two second sub pixels in two pixel of the units adjacent along the row direction in the pixel array are disposed in the same sub pixel row, and two third sub pixels in two of the pixel units adjacent along the row direction in the pixel array are disposed in another sub pixel row.

Claims

1. A pixel array comprising a plurality of pixel units repeatedly arranged along a row direction and a column direction, wherein each of the pixel units comprises:

two first sub pixels;

a second sub pixel; and

a third sub pixel, wherein

the second sub pixel and the third sub pixel are disposed in adjacent two sub pixel rows, and the two first sub pixels are disposed in adjacent two sub pixel rows, such that two second sub pixels in two of the pixel units adjacent along the row direction in the pixel array are disposed in the same sub pixel row, and two third sub pixels in two of the pixel units adjacent along the row direction in the pixel array are disposed in another sub pixel row.

2. The pixel array according to claim 1, wherein lines connecting centers of the four sub pixels of each of the pixel units form a quadrilateral shape, and the two first sub pixels are disposed at diagonal positions of the quadrilateral shape.

3. The pixel array according to claim 1, wherein in each of the pixel units:

the two first sub pixels are disposed in the same sub pixel column.

4. The pixel array according to claim 1, wherein in each of the pixel units:

the two first sub pixels have the same area size.

5. The pixel array according to claim 1, wherein in each of the pixel units:

the two first sub pixels have different area sizes.

6. The pixel array according to claim 5, wherein any one of the two first sub pixels at corresponding positions in the pixel units has the same area size.

7. The pixel array according to claim 1, wherein in each of the pixel units:

a sum of the areas of the two first sub pixels are greater than an area of the second sub pixel or an area of the third sub pixel, and is smaller than a sum of the areas of the second sub pixel and the third sub pixel.

8. The pixel array according to claim 1, wherein the sub pixels have one or more shapes of triangle, quadrilateral, polygon and circular shape.

9. A display apparatus comprising a pixel array, wherein the pixel array comprises a plurality of pixel units repeatedly arranged along a row direction and a column direction, wherein each of the pixel units comprises:

two first sub pixels;

a second sub pixel; and

a third sub pixel, wherein

the second sub pixel and the third sub pixel are disposed in adjacent two sub pixel rows, and the two first sub pixels are disposed in adjacent two sub pixel rows, such that two second sub pixels in two of the pixel units adjacent along the row direction in the pixel array are disposed in the same sub pixel row, and two third sub pixels in two of the pixel units adjacent along the row direction in the pixel array are disposed in another sub pixel row.

10. The display apparatus according to claim 9, wherein lines connecting centers of the four sub pixels of each of the pixel units form a quadrilateral shape, and the two first sub pixels are disposed at diagonal positions of the quadrilateral shape.

11. The display apparatus according to claim 9, wherein in each of the pixel units:

the two first sub pixels are disposed in the same sub pixel column.

12. The display apparatus according to claim 9, wherein in each of the pixel units:

the two first sub pixels have the same area size.

13. The display apparatus according to claim 9, wherein in each of the pixel units:

the two first sub pixels have different area sizes.

14. The display apparatus according to claim 13, wherein any one of the two first sub pixels at corresponding positions in the pixel units has the same area size.

15. The display apparatus according to claim 9, wherein in each of the pixel units:

a sum of the areas of the two first sub pixels are greater than an area of the second sub pixel or an area of the third sub pixel, and is smaller than a sum of the areas of the second sub pixel and the third sub pixel.

16. The display apparatus according to claim 9, wherein the sub pixels have one or more shapes of triangle, quadrilateral, polygon and circular shape.
