Document Type and Number:
WIPO Patent Application WO/2020/102985
Kind Code:
A1
Abstract:
A display substrate includes a base substrate (BS)and a plurality of light emitting brightness value detectors (D) on the base substrate (BS). Each of the plurality of light emitting brightness value detectors (D) includes a first thin film transistor (T1); a protection layer (PL) on a side of the first thin film transistor (T1) away from the base substrate (BS); and a photosensor (PS) electrically connected to the first thin film transistor (T1) and configured to detect a light emitting brightness value. An orthographic projection of the protection layer (PL) on the base substrate (BS) covers an orthographic projection of at least a channel part of the first thin film transistor (T1) on the base substrate (BS).
