Driving method for pixel driving circuit, display panel and display device
A driving method for a pixel driving circuit comprising a driving transistor and a light-emitting element is provided. The driving method comprises: in response to a first scanning signal on a first scanning signal line, performing initialization of the pixel driving circuit; in response to a second scanning signal on a second scanning signal line and the first scanning signal on the first scanning signal line, compensating threshold voltage deviation of the driving transistor and providing a data signal voltage; in response to a first light-emitting signal on a first light-emitting signal line and a second light-emitting signal on a second light-emitting signal line, generating, by the driving transistor, driving current corresponding to the data signal voltage; and in response to the driving current, emitting light by the light-emitting element. At least one clock signal period is provided after initialization is completed and before the threshold voltage deviation is compensated.
