Abstract
Provided are a display panel and a driving method thereof, and a display device. A light emission control transistor of a pixel driving circuit in the display panel is connected in series between the anode of a light-emitting element and a first power signal line. A cathode switch transistor is connected in series between the cathode of the light-emitting element and a second power signal line. In at least one light emission stage, the time when the cathode switch transistor is turned on lags behind the time when the light emission control transistor is turned on.
