Abstract:
Disclosed are a method for driving a pixel circuit, a display panel and a display device. The pixel circuit includes: a data write module, a drive transistor, a hold module and a light-emitting element. The method comprises, in a time period for a frame of display: a data writing stage in which a data signal is written by the data write module into a gate electrode of the drive transistor; a light-emitting stage in which a voltage on the gate electrode of the drive transistor is held by the hold module, the drive transistor supplies a drive current to the light-emitting element, and the light-emitting element emits light in response to the drive current; and a cut-off stage in which the drive transistor operates in a full cut-off region.
