The pixel structure includes a number of pixel groups arranged in an array. Each of the pixel groups includes a first pixel sub-group and a second pixel sub-group disposed adjacent to each other in a first direction and misaligned with each other in a second direction perpendicular to the first direction. The first pixel sub-group and the second pixel sub-group include sub-pixel groups of three different colors including a first sub-pixel group, a second sub-pixel group, and a third sub-pixel group. Each sub-pixel group includes four sub-pixels of a same color, and the sub-pixel groups of a same color are alternately arranged in a regular manner. ## Claims ### Claim 1 A pixel structure, comprising a plurality of pixel groups arranged in an array, each of the pixel groups comprising a first pixel sub-group and a second pixel sub-group disposed adjacent to each other and misaligned with each other, each of the first pixel sub-group and the second pixel sub-group comprising sub-pixel groups of three different colors comprising a first sub-pixel group, a second sub-pixel group, and a third sub-pixel group, each of the sub-pixel groups comprising four sub-pixels of a same color, wherein each of the pixel groups is divided into at least one pixel unit, and each pixel unit comprises sub-pixels of three different colors, wherein in a same pixel group, at least one sub-pixel in the first pixel sub-group and/or the second pixel sub-group is shared to form a corresponding pixel unit. ### Claim 2 (depends on 1) The pixel structure according to claim 1, wherein in each of the pixel groups, the first pixel sub-group and the second pixel sub-group are disposed adjacent to each other in a first direction and are misaligned with each other in a second direction perpendicular to the first direction. ### Claim 3 (depends on 2) The pixel structure according to claim 2, wherein the first direction is a row direction, and the second direction is a column direction;
