1. A display substrate, wherein the display substrate has a central region and an edge region, and the display substrate comprises a plurality of structural units arranged in an array in the central region and the edge region;
wherein each structural unit is provided with a plurality of through holes, and divided by the plurality of through holes into a pixel island for displaying and a bridge portion for transmitting signals; the plurality of through holes are arranged around the pixel island; a part of the bridge portion is positioned between the pixel island and the through holes, and another part of the bridge portion is positioned between adjacent through holes; and
wherein a pixel pitch between adjacent pixel islands in the structural units in the edge region is equal to a pixel pitch between adjacent pixel islands in the structural units in the central region, and both are equal to a first pixel pitch,
wherein the through hole comprises a first long-strip-shaped hole and second long-strip-shaped holes located at opposite ends of the first long-strip-shaped hole, and the first long-strip-shaped hole is communicated with the second long-strip-shaped holes; a length direction of the first long-strip-shaped hole intersects with a length direction of the second long-strip-shaped holes, and a center point of the first long-strip-shaped hole and center points of the second long-strip-shaped holes are on a same straight line; and
wherein a length of the first long-strip-shaped hole is greater than a length of the second long-strip-shaped holes.
