Abstract

A pixel structure is disclosed. The pixel structure includes a plurality of sub-pixel groups arranged in an array, wherein each sub-pixel group is constituted by 6 sub-pixels of different colors arranged in two rows and three columns respectively. In each row of the sub-pixels, a square pixel unit is constituted by at most two adjacent sub-pixels. The present application further discloses a display panel and a driving method of said pixel structure.

First claim

The invention claimed is:

1. A method for driving a pixel structure, comprising:
receiving original image information of a frame to be displayed;
determining a corresponding sampling area of each sub-pixel in the pixel structure based on the color arrangement order of the sub-pixels in each sub-pixel group in the pixel structure; the corresponding sampling area of each sub-pixel comprising a square pixel unit constituted by the sub-pixel and at least partial adjacent square pixel unit;
determining a weight of each square pixel unit comprised in the sampling area in the corresponding sampling area of each sub-pixel based on a proportion of area occupied by the square pixel unit comprised in the determined corresponding sampling area of each sub-pixel in the sampling area;
determining a gray scale value that needs to be displayed by each sub-pixel based on the weight of each square pixel unit comprised in the sampling area in the corresponding sampling area of each sub-pixel and a corresponding gray scale value of each square pixel unit with a same color as the sub-pixel in the original image information of the frame to be displayed;
performing display based on the determined gray scale value that needs to be displayed by each sub-pixel.

2. The method as claimed in claim 1 , wherein the step of determining a corresponding sampling area of each sub-pixel in the pixel structure based on the color arrangement order of the sub-pixels in each sub-pixel group in the pixel structure specifically comprises:
when the color arrangement orders of sub-pixels in two adjacent sub-pixel groups in the row direction are the same, the corresponding sampling area of each sub-pixel in the pixel structure being: a rectangular sampling area that takes the sub-pixel as the center and overlaps with 9 square pixel units arranged in three rows and three columns respectively; and corresponding sampling areas of sub-pixels of the same color being in continuous distribution.

3. The method as claimed in claim 1 , wherein the step of determining a corresponding sampling area of each sub-pixel in the pixel structure based on the color arrangement order of the sub-pixels in each sub-pixel group in the pixel structure specifically comprises:
when the color arrangement orders of sub-pixels in two adjacent sub-pixel groups in the row direction are the same, the corresponding sampling area of a sub-pixel of three primary colors in the pixel structure being: a rectangular sampling area that takes the sub-pixel as the center and overlaps with 9 square pixel units arranged in three rows and three columns respectively; and corresponding sampling areas of sub-pixels of the same primary color being in continuous distribution;
when the color arrangement order of sub-pixels in two adjacent sub-pixel groups in the row direction are the same, the corresponding sampling area of a sub-pixel of three mixed colors in the pixel structure being: a square pixel unit constituted by the sub-pixel and a square pixel unit adjacent in the row direction; and corresponding sampling areas of sub-pixels of the same mixed color being in continuous distribution in the row direction.

4. The method as claimed in claim 1 , wherein the step of determining a corresponding sampling area of each sub-pixel in the pixel structure based on the color arrangement order of the sub-pixels in each sub-pixel group in the pixel structure specifically comprises:
when a color arrangement order of an odd row of sub-pixels in a sub-pixel group in the row direction is the same as a color arrangement order of an even row of sub-pixels in an adjacent sub-pixel group, the corresponding sampling area of each sub-pixel in the pixel structure being: a rectangular sampling area that takes the sub-pixel as the center and overlaps with 15 square pixel units arranged in three rows and five columns respectively; and corresponding sample areas of odd rows of sub-pixels of the same color being in continuous distribution, corresponding sampling areas of even rows of sub-pixels of the same color being in continuous distribution.

5. The method as claimed in claim 1 , wherein the step of determining a corresponding sampling area of each sub-pixel in the pixel structure based on the color arrangement order of the sub-pixels in each sub-pixel group in the pixel structure specifically comprises:
when a color arrangement order of an odd row of sub-pixels in a sub-pixel group in the row direction is the same as a color arrangement order of an even row of sub-pixels in an adjacent sub-pixel group, the corresponding sampling area of a sub-pixel of three primary colors in the pixel structure being: a rectangular sampling area that takes the sub-pixel as the center and overlaps with 15 square pixel units arranged in three rows and five columns respectively; and corresponding sample areas of odd rows of sub-pixels of the same color being in continuous distribution, corresponding sampling areas of even rows of sub-pixels of the same color being in continuous distribution;
when a color arrangement order of an odd row of sub-pixels in a sub-pixel group in the row direction is the same as a color arrangement order of an even row of sub-pixels in an adjacent sub-pixel group, the corresponding sampling area of a sub-pixel of three mixed colors in the pixel structure being: a square pixel unit constituted by the sub-pixel and a square pixel unit adjacent in the row direction; and corresponding sampling areas of sub-pixels of the same mixed color being in continuous distribution in the row direction.
