1. A display substrate, comprising:
a flexible substrate body comprising a plurality of island portions spaced apart from each other, a plurality of connection areas connecting the plurality of island portions, and a penetration portion penetrating the substrate body among the plurality of connection areas, wherein at least a portion of each edge of the island portion is connected with the connection area;
each island portion is respectively provided with a plurality of pixel groups, each pixel group comprises a first pixel unit and a second pixel unit which are adjacently arranged along a first direction, an arrangement of the sub-pixels in the first pixel unit is different from an arrangement of the sub-pixels in the second pixel unit, the plurality of pixel groups form an n×m arrangement on the island portion and cover the whole island portion; the first direction is a direction parallel to one edge of the island portion;
where n represents a number of the pixel groups in a row direction, m represents a number of the pixel groups in a column direction, and n and m are integers greater than or equal to 1, respectively;
wherein a shape of the penetration portion changes when the substrate body is stretched.
