Abstract

A pixel arrangement structure includes: first sub-pixels, second sub-pixels and third sub-pixels, all being not overlapped but being spaced apart. The third sub-pixels have a first symmetry axis and a second symmetry axis that are perpendicular to each other. The first symmetry axis extends through a geometric center of a respective first sub-pixel adjacent to a respective third sub-pixel of the plurality of third sub-pixels, intersects a first edge of the respective third sub-pixel at a first intersection point, and intersects a second edge of the adjacent respective first sub-pixel at a second intersection point. A distance between the first intersection point and the second intersection point is a minimum distance between the respective third sub-pixel and the respective first sub-pixel. The second symmetry axis is similarly configured with respect to a respective second sub-pixel and the respective third sub-pixel.
