Abstract

The present disclosure is related to a pixel arrangement structure. The pixel arrangement structure may include a plurality of first repeating units and a plurality of second repeating units alternately arranged in both a first direction and a second direction. Each of the plurality of the first repeating units may comprise a first sub-pixel or a second sub-pixel, and each of the plurality of the second repeat units may comprise a third sub-pixel or a second sub-pixel. Second sub-pixels may be uniformly distributed in an array. At least some of first sub-pixels have a shape of a concave polygon, and at least some of third sub-pixels have a shape of a convex polygon.
