Claim 0:
1. A display substrate, comprising a display region and a binding region located at one side of the display region, wherein
the display region comprises a driving structure layer, an organic insulating layer disposed on the driving structure layer and a light-emitting element disposed on the organic insulating layer, the driving structure layer comprises a pixel driving circuit, and the light-emitting element is connected with the pixel driving circuit;
the binding region comprises a binding structure layer, an organic insulating layer and an isolation dam disposed on the binding structure layer, and an inorganic encapsulation layer disposed on the organic insulating layer and the isolation dam, the binding structure layer comprises a power line connected with the pixel driving circuit; and
at least one isolation groove is disposed on the organic insulating layer of the binding region, the inorganic encapsulation layer covers the isolation groove and wraps the isolation dam, and the distance between the isolation groove and an edge of the display region is smaller than the distance between the isolation dam and the edge of the display region;
wherein the power line comprises a first power line and a second power line, and the isolation groove is disposed on the first power line;
wherein along the direction of the edge of the display region, an orthographic projection of the isolation groove on a substrate comprises an orthographic projection of the first power line on the substrate;
wherein a surface of the first power line is exposed in the isolation groove, and the encapsulation layer covers the exposed surface of the first power line in the isolation groove.
