摘要:
Provided are a pixel driving circuit, a driving method and a display panel. The pixel driving circuit includes a driving transistor, a storage sub-circuit, a data writing sub-circuit, an initialization sub-circuit, a first light-emission control sub-circuit, a second light-emission control sub-circuit and a light-emitting element. The data writing sub-circuit is configured to write a data signal to a first electrode of the driving transistor in response to a second scan signal. The storage sub-circuit is configured to store the data signal written by the data writing sub-circuit. The initialization sub-circuit is configured to apply a reset voltage of an initial voltage terminal to the light-emitting element in response to a first scan signal. The first light-emission control sub-circuit is configured to apply a voltage of a first power terminal to the first electrode of the driving transistor in response to a first light-emission signal.
