Abstract
This disclosure provides a display substrate and a display device. One embodiment of the display substrate includes N light detection circuits, each comprising a light-sensing sub-circuit and a sampling sub-circuit, where N is an integer greater than or equal to 1. The light-sensing sub-circuit includes an input terminal, a control terminal, and an output terminal, configured to output a light-sensing signal based on signals from the input terminal and the control terminal. A first terminal of the sampling sub-circuit is electrically connected to the output terminal of the light-sensing sub-circuit, and a second terminal is grounded, configured to sample the light-sensing signal to generate a sampling voltage. The sampling sub-circuit is an equivalent resistor disposed within the display substrate. This embodiment of the display substrate utilizes an inner film layer to implement an equivalent resistor for sampling, achieving integration and design flexibility of the light detection circuit.
