Abstract

The present disclosure proposes a pixel circuit and a display panel. The pixel circuit includes a driving transistor, a light-emitting device, a feedback transistor, and a feedback capacitor. By coupling the feedback transistor and feedback capacitor between the gate of the driving transistor and the anode of the light-emitting device, the pixel circuit and display panel can make the voltage level of the gate of the driving transistor change correlatively with the voltage level of the anode of the light-emitting device. This can reduce the brightness change of the light-emitting device, and improves the brightness of the light-emitting device.
