1. A pixel arrangement structure, comprising:
a plurality of sub-pixels arranged such that they are not overlapped with but are spaced apart from one another, comprising: a plurality of first sub-pixels, a plurality of second sub-pixels and a plurality of third sub-pixels, wherein a respective third sub-pixel comprises a first edge facing a respective first sub-pixel, the respective first sub-pixel comprises a second edge facing the respective third sub-pixel, the respective third sub-pixel comprises a third edge facing a respective second sub-pixel, and the respective second sub-pixel comprises a fourth edge facing the respective third sub-pixel,
wherein:
each of a shape of the respective first sub-pixel and a shape of the respective second sub-pixel is a circle, the first edge and the second edge are both curved edges with a same curvature, and the third edge and the fourth edge are both curved edges with a same curvature; or
each of a shape of the respective first sub-pixel and a shape of the respective second sub-pixel is an octagon, at least part of the first edge is parallel to at least part of the second edge, and at least part of the third edge is parallel to at least part of the fourth edge.
