Abstract

See full text

The display substrate includes: a substrate; a plurality of pixel units on the substrate, each pixel unit includes a plurality of sub-pixels, each sub-pixel includes a light-emitting element and a pixel drive circuit; a photosensitive circuit on the substrate; a first conductive film layer on the substrate. The pixel drive circuit includes a drive transistor, a gate electrode of the drive transistor is located on a side of a drive active layer away from the substrate, an orthographic projection of the gate electrode of the drive transistor on the substrate at least partially overlaps an orthographic projection of the drive active layer on the substrate. The first conductive film layer includes a first light-shielding portion between the substrate and the drive active layer, and an orthographic projection of the first light-shielding portion on the substrate at least partially overlaps the orthographic projection of the drive active layer on the substrate.
