Abstract
A pixel circuit, a display panel, and a display device comprising the pixel circuit. The pixel circuit comprises a light emitting element and a driving circuit. The driving circuit comprises a light emission driving circuit for driving the light emitting element to emit light, and a light sensing driving circuit for controlling the light emitting element to convert external light incident on the light emitting element into an electrical signal. The pixel circuit integrates the light emission driving circuit with the light sensing driving circuit and can achieve the light sensing function for the screen of the display device, which makes it possible to not reserve an area dedicated to a camera on the surface of the display device.
