1. A pixel arrangement structure, comprising:
a plurality of sub-pixels which 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 the third sub-pixels comprise 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 of the plurality of first sub-pixels adjacent to a respective third sub-pixel of the plurality of third sub-pixels, the first symmetry axis 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, the first edge is an edge of the respective third sub-pixel on a side of the respective third sub-pixel facing the respective first sub-pixel, and the second edge is an edge of the respective first sub-pixel on a side of the respective first sub-pixel facing the respective third sub-pixel, and 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 extends through a geometric center of a respective second sub-pixel of the plurality of second sub-pixels adjacent to the respective third sub-pixel, the second symmetry axis intersects a third edge of the respective third sub-pixel at a third intersection point and intersects a fourth edge of the adjacent respective second sub-pixel at a fourth intersection point, the third edge is an edge of the respective third sub-pixel on a side of the respective third sub-pixel facing the respective second sub-pixel, and the fourth edge is an edge of the respective second sub-pixel on a side of the respective second sub-pixel facing the respective third sub-pixel, and a distance between the third intersection point and the fourth intersection point is a minimum distance between the respective third sub-pixel and the respective second sub-pixel.
