Abstract

A pixel structure, a driving method thereof, a display panel, and a display apparatus are provided. The pixel structure includes: a plurality of pixel rows and a plurality of pixel columns. Each pixel row includes: sub-pixels of four different colors. The plurality of pixel columns include: a plurality of first pixel columns and a plurality of second pixel columns arranged alternately. Each of the first pixel columns includes: sub-pixels of three of the four different colors. Each of the second pixel columns includes: sub-pixels of another color other than the three of the four different colors.

First claim

The invention claimed is:

1. A pixel structure, comprising:
a plurality of pixel rows and a plurality of pixel columns, wherein each pixel row comprises: sub-pixels of four different colors; the plurality of pixel columns comprise: a plurality of first pixel columns and a plurality of second pixel columns arranged alternately; each first pixel column comprises: sub-pixels of three of the four different colors; each second pixel column comprises: sub-pixels of another color other than the three of the four different colors.

2. The pixel structure according to claim 1 , wherein each pixel row is arranged in a straight line shape.

3. The pixel structure according to claim 1 , wherein each pixel column is arranged in a bent line shape.

4. The pixel structure according to claim 1 , wherein quantities of the sub-pixels of three colors of the first pixel column are equal.

5. The pixel structure according to claim 1 , wherein a total quantity of the sub-pixels of the second pixel column is equal to a total quantity of the sub-pixels of the first pixel column.

6. The pixel structure according to claim 1 , wherein a ratio of the quantities of the sub-pixels of the four different colors in each pixel row is 1:1:1:3.

7. The pixel structure according to claim 1 , wherein colors of adjacent sub-pixels in each pixel row are different.

8. The pixel structure according to claim 1 , wherein colors of adjacent sub-pixels in each first pixel column are different.

9. The pixel structure according to claim 1 , wherein colors of adjacent sub-pixels in adjacent first pixel columns of the plurality of pixel columns are different.

10. The pixel structure according to claim 1 , further comprising: a plurality of data signal lines, wherein each second pixel column is controlled through a data signal line, and each first pixel column is controlled through two data signal lines.

11. The pixel structure according to claim 1 , wherein in a case that the pixel structure is in a first display mode, the pixel structure displays by taking a pixel row group formed by two adjacent pixel rows as a unit; or, in a case that the pixel structure is in a second display mode, the pixel structure displays by taking a pixel column group formed by a first pixel column and a second pixel column as a unit.

12. A pixel structure, comprising:
a plurality of pixels arranged in an array, wherein each pixel comprises: sub-pixels of four different colors; and in each pixel, a ratio of quantities of the sub-pixels of four different colors is 1:1:1:3.

13. The pixel structure according to claim 12 , wherein each sub-pixel has a shape of a hexagon; and six internal angles of the hexagon are all 120°.

14. The pixel structure according to claim 13 , wherein three groups of opposite sides of the hexagon are parallel to each other; and lengths of at least two groups of the opposite sides are equal.

15. The pixel structure according to claim 12 , wherein the sub-pixels of three of the four different colors comprises: a red sub-pixel, a blue sub-pixel, and a green sub-pixel, and the sub-pixel of another color other than three of the four different colors is a white sub-pixel.

16. The pixel structure according to claim 15 , wherein an area of the blue sub-pixels is greater than an area of the red sub-pixels and an area of the green sub-pixels.

17. The pixel structure according to claim 12 , further comprising: a plurality of data signal lines, wherein the sub-pixels of three of the four different colors in each pixel are controlled by two data signal lines; and the sub-pixels of another color other than three of the four different colors in each pixel are controlled by a same data signal line.

18. The pixel structure according to claim 15 , further comprising: a plurality of repeating units arranged in an array, wherein each repeating unit comprises: three pixels arranged side by side, and arrangement positions of the sub-pixels of the four different colors in the three pixels are different.

19. The pixel structure according to claim 18 , wherein the three pixels comprise: a first pixel, a second pixel, and a third pixel, wherein a first row of the first pixel comprises: a red sub-pixel and a white sub-pixel arranged in sequence; a second row of the first pixel comprises: a blue sub-pixel and a white sub-pixel arranged in sequence; a third row of the first pixel comprises: a green sub-pixel and a white sub-pixel arranged in sequence; a first row of the second pixel comprises: a green sub-pixel and a white sub-pixel arranged in sequence; a second row of the second pixel comprises: a red sub-pixel and a white sub-pixel arranged in sequence; a third row of the second pixel comprises: a blue sub-pixel and a white sub-pixel arranged in sequence; a first row of the third pixel comprises: a blue sub-pixel and a white sub-pixel arranged in sequence; a second row of the third pixel comprises: a green sub-pixel and a white sub-pixel arranged in sequence; and a third row of the third pixel comprises: a red sub-pixel and a white sub-pixel arranged in sequence.
