Claim 0:
1. A display substrate, comprising: a drive structure layer disposed on a substrate, a light-emitting element disposed on the drive structure layer, and a light detection unit disposed on the light-emitting element; wherein the light detection unit is disposed in a direction of light emitting of the light emitting element to detect brightness of the light emitting element
wherein the drive structure layer comprises a pixel drive circuit, the light-emitting element comprises a first electrode, an organic functional layer and a second electrode which are stacked on the drive structure layer, and the first electrode is connected with the pixel drive circuit; and
the light detection unit comprises a third electrode, a photosensitive active layer and a fourth electrode which are stacked;
the display substrate further comprising: a capping layer disposed between the second electrode and the third electrode;
wherein the third electrode of the light detection unit is disposed on the capping layer, wherein the third electrode of the light detection unit is an integrated structure for different pixel units and connected with a low voltage line in a peripheral region of the display substrate.
