Abstract

The present disclosure provides a pixel structure. The pixel structure includes first sub-pixels, second sub-pixels, and third sub-pixels. In the pixel structure, two adjacent third sub-pixels facing each other form a third sub-pixel group, the second sub-pixels are arranged along a direction of a first axis to form second-sub-pixel rows. The second sub-pixels are arranged along a direction of a second axis to form second-sub-pixel columns, the first sub-pixels and the third sub-pixel groups are arranged in an alternating configuration along the direction of the column axis, the second-sub-pixel columns and columns formed by the first sub-pixels and the third sub-pixel groups are arranged in an alternating configuration. Geometric center of each second sub-pixel is positioned on a perpendicular bisector of a line connecting centers of any two of adjacent third sub-pixel groups and first sub-pixels.
