1. A display substrate, comprising:
a base substrate;
a metal light-shielding layer disposed on the base substrate;
a plurality of pixel units disposed on the base substrate;
a plurality of first thin film transistors disposed on the metal light-shielding layer and configured to drive the pixel units;
a plurality of photodiodes disposed on the metal light-shielding layer and configured to convert light emitted from the pixel units into photocurrents; and
a plurality of second thin film transistors disposed on the metal light-shielding layer and configured to receive the photocurrents so that light emission of the pixel units are compensated according to the photocurrents;
wherein output terminals of the first thin film transistors are electrically connected to the metal light-shielding layer.
