Abstract

See full text

A display panel including light-sensing devices and light-detection circuits. The light-detection circuit includes a sensing module, a reading module, and a resetting module. The sensing module includes a control terminal electrically connected to the light-sensing device and the resetting module, an input terminal electrically connected to a first signal line, and an output terminal electrically connected to the reading module. Further, a first light-sensing device is electrically connected to the control terminal of the sensing module in a first light-detection circuit, and a second light-sensing device is electrically connected to the control terminal of the sensing module in a second light-detection circuit. The second light-detection circuit further includes a first capacitor, and the first capacitor is electrically connected to the control terminal of the sensing module in the second light-detection circuit.
