1. A display substrate, comprising:
a base substrate, comprising a display region and a non-display region on a side of the display region;
an encapsulation dam, located in the non-display region and arranged around the display region, wherein an orthographic projection of the encapsulation dam on the base substrate does not overlap with the display region;
an organic insulating layer on the base substrate; wherein the organic insulating layer has a groove structure, and the groove structure is disposed on a side of the encapsulation dam facing away from the display region; wherein the non-display region comprises a bending region, and the groove structure is located between the encapsulation dam and the bending region;
a touch structure on a side of the organic insulating layer facing away from the base substrate, wherein the touch structure comprises a plurality of touch lines extending to the non-display region; and
an inorganic insulating layer at the side of the organic insulating layer facing away from the base substrate, wherein the inorganic insulating layer has a hollowed-out structure exposing the groove structure on the side of the encapsulation dam away from the display region, and an orthographic projection of the hollowed-out structure does not overlap with orthographic projections of the plurality of touch lines on the base substrate.
