Abstract

An OLED pixel arrangement structure includes multiple first sub-pixels, multiple second sub-pixels and multiple third sub-pixels. Four adjacent ones of the first sub-pixels and four adjacent ones of the second sub-pixels are alternately arranged and surround one of the third sub-pixels. Centers of the four adjacent first sub-pixels and centers of the four adjacent second sub-pixels form vertexes of a virtual octagonal cell, and the virtual octagonal cell has at least two orthogonal symmetry axes, a basic pixel unit is formed by the first sub-pixels and the second sub-pixels forming the virtual octagonal cell and a part of the third sub-pixel inside the virtual octagonal cell which are located on one side of one of the at least two orthogonal symmetry axes of the virtual octagonal cell. A center of the third sub-pixel coincides with a center of the virtual octagonal cell.
