a plurality of first sub-pixel groups, wherein each of the plurality of first sub-pixel groups comprises a first sub-pixel and at least two second sub-pixels, the at least two second sub-pixels have different emission colors, the first sub-pixel is disposed around the at least two second sub-pixels, an emission color of the first sub-pixel is different from an emission color of any one of the at least two second sub-pixels; and

a plurality of third sub-pixels,

wherein an emission color of each of the plurality of third sub-pixels is different from the emission color of the first sub-pixel; wherein in a first direction, one of the plurality of first sub-pixel groups and one of the plurality of third sub-pixels adjacent to the one of the plurality of first sub-pixel groups constitute a pixel unit, and a plurality of pixel units are arranged in an array; wherein in a direction vertical to the first direction, two adjacent ones of the plurality of pixel units constitute a pixel unit group; and wherein two pixel units in a same pixel unit group have a same structure, or arrangement orders of a first sub-pixel group and a third sub-pixel in two pixel units in a same pixel unit group in the first direction are different;

wherein the pixel unit group is a minimum repeating unit in the pixel structure.
