1. A pixel array, comprising first sub-pixels, second sub-pixels and third sub-pixels; wherein
the first sub-pixels and the third sub-pixels are alternately arranged along a first direction to form first pixel groups, and are alternately arranged along a second direction to form third pixel groups; the second sub-pixels are arranged along the first direction to form second pixel groups, and are arranged along the second direction to form fourth pixel groups;
the first pixel groups and the second pixel groups are alternately arranged in the second direction; the third pixel groups and the fourth pixel groups are alternately arranged along the first direction; and
a shape of each of the second sub-pixels comprises a polygon, a plurality of sides of the polygon comprise straight lines or arcs, and the shape of the second sub-pixel comprises at most one symmetry axis; and
the shape of each of the second sub-pixels comprises a quadrangle, which comprises two pairs of opposite corners; in one pair of opposite corners, a closest distance from an intersection point between extension lines of two sides of one corner to a boundary of the second sub-pixel is different from a closest distance from an intersection point between extension lines of two sides of the other corner to the boundary of the second sub-pixel, and in the other pair of opposite corners, a closest distance from an intersection point between extension lines of two sides of one corner to the boundary of the second sub-pixel is equal to a closest distance from an intersection point between extension lines of two sides of the other corner to the boundary of the second sub-pixel.
