Abstract

A display panel includes a pixel circuit. The pixel circuit includes a write-in compensation module for writing data signal(s) into a light emission device through a driving transistor and compensating a threshold voltage of the driving transistor; a first reset module for providing a signal of a first reset signal end to a gate of the driving transistor under control of a first reset control end; a second reset module for providing a signal of a second reset signal end to an anode of the light emission device under control of a second reset control end; and a light emission control module for connecting a drain electrode of the driving transistor with the anode under control of a light emission control end. A cathode of the light emission device is connected with a first power source voltage end.
