Abstract
A pixel circuit includes an input module, an emission control module, a compensation module, a driving transistor and a light emitting device. The input module is configured to provide a signal of a data signal terminal to a gate of the driving transistor and provide a signal of an initialization signal terminal to a second electrode of the driving transistor. The compensation module is configured to provide a signal of a power supply voltage terminal to a first electrode of the driving transistor. The emission control module is configured to provide a signal of a reference voltage signal terminal to the gate of the driving transistor and conduct the second electrode of the driving transistor with the light emitting device.
