Abstract
Provided is a display substrate, which includes a base substrate, a circuit structure layer disposed on the base substrate, multiple ultrasonic sensing elements and multiple micro light-emitting elements. The multiple ultrasonic sensing elements are disposed on a side of the circuit structure layer away from the base substrate, and are electrically connected to the circuit structure layer, and the multiple light-emitting elements are disposed on the side of the circuit structure layer away from the base substrate, and are electrically connected to the circuit structure layer. An orthographic projection of the multiple ultrasonic sensing elements on the base substrate does not overlap with an orthographic projection of the multiple micro light-emitting elements on the base substrate.
