Claim 19:
20. A driving method of a pixel circuit, wherein the pixel circuit comprises a drive module, a first initialization module and a data write module; the first initialization module is controlled by a first scan signal and a second scan signal, and the data write module is controlled by a third scan signal; and
wherein the driving method comprises:
an initialization stage in which the first scan signal and the second scan signal are active to control the first initialization module to initialize a control terminal of the drive module;
a data write stage in which the second scan signal and the third scan signal are active to control the first initialization module to cooperate with the data write module to write a data signal into the control terminal of the drive module; and
a light emission stage in which the drive module generates, in response to the data signal, a drive current to drive a light-emitting element to emit light;
wherein the first scan signal, the second scan signal and the third scan signal have a same waveform shape and a same delay time interval, and scan signals of the pixel circuit multiplex scan signals of previous pixel circuits.
