Abstract
A pixel circuit, a driving method thereof, and a display panel. The pixel circuit includes a drive module, a first initialization module and a data write module. The drive module is configured to generate, in response to a data signal, a drive current to drive a light-emitting element to emit light. The first initialization module is controlled by a first scan signal and a second scan signal and is configured to initialize a control terminal of the drive module when the first scan signal and the second scan signal are active. The data write module is controlled by a third scan signal, where the first initialization module is configured to cooperate with the data write module to write the data signal into the control terminal of the drive module when the second scan signal and the third scan signal are active.
