Abstract:
Disclosed are a pixel circuit, a display panel and a drive method for a pixel circuit. The pixel circuit comprises: a light-emitting element, configured for emitting light in response to a drive current; a drive transistor, configured for providing the drive current to the light-emitting element; a data write device, configured for writing a data signal to a gate electrode of the drive transistor; a hold device, electrically connected with the gate electrode of the drive transistor and configured for holding a voltage on the gate electrode of the drive transistor in a light-emitting stage; and a control device, electrically connected with the gate electrode of the drive transistor and configured for controlling the drive transistor to operate in a full cut-off region in a cut-off stage, wherein, the cut-off stage precedes the light-emitting stage.
