Abstract
A driving method for driving a pixel circuit. The pixel circuit includes a driving transistor, a data-writing transistor, a compensating transistor, a first initializing transistor, a second initializing transistor and a light-emitting element. The compensating transistor is connected between a gate of the driving transistor and a second pole of the driving transistor. The second pole of the driving transistor is connected to an initialization power supply through the first initializing transistor. The data-writing transistor is connected between a data voltage input terminal and a first pole of the driving transistor. The second initializing transistor is connected between a first signal terminal and a first pole of the driving transistor; and the light-emitting element is connected between the second pole of the driving transistor and a second power voltage input terminal.
