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.

Claims

1. A method for driving a pixel structure, comprising:

receiving original image information of a frame to be displayed;

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.
