Abstract: The present disclosure relates to an organic light-emitting display substrate and a display device. The organic light-emitting display substrate includes a plurality of rows of sub-pixels, each of which includes first sub-pixels, second sub-pixels and third sub-pixels repeatedly arranged, and two adjacent rows of sub-pixels are arranged in a staggered manner, in every two adjacent rows of sub-pixels: a first sub-pixel in one row of sub-pixels and a second sub-pixel and a third sub-pixel that are adjacent to the first sub-pixel in the other row of sub-pixels, form a pixel unit, and white light brightness centers of the pixel units in a same row are located on a same straight line.

Abstract: A pixel arrangement including first groups of sub-pixels arranged in a first direction, each of the first groups including first sub-pixels and third sub-pixels arranged alternately and second groups of sub-pixels arranged in the first direction, each of the second groups including third sub-pixels and second sub-pixels arranged alternately. The first groups and the second groups are alternately arranged in a second direction intersecting the first direction. The first groups and the second groups are arranged to form third groups of sub-pixels arranged in the second direction and fourth groups of sub-pixels arranged in the second direction. The third groups and the fourth groups are alternately arranged in the first direction. Each of the third groups includes first sub-pixels and third sub-pixels arranged alternately. Each of the fourth groups includes third sub-pixels and second sub-pixels arranged alternately.

Abstract: A pixel arrangement structure may include a plurality of repeating units (100). Each of the plurality of the repeating units (100) may include a first sub-pixel (01) being at a center point of a virtual hexagon and second sub-pixels (02) and third sub-pixels (03) being alternately arranged at vertices of the virtual hexagon. Virtual hexagons of adjacent repeating units may share one common side as well as two sub-pixels on the common side.
