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.

Claim (Index 16):
A drive method for a pixel circuit, which is configured for driving a pixel circuit, wherein the pixel circuit comprises:\n 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-offstage precedes the light-emitting stage; wherein the drive method comprises the following stages: a cut-off stage, in which the control device is turned on, a cut-off signal is written to a gate electrode of the drive transistor, and thus the drive transistor operates in a full cut-off region; a data-write stage, in which the control device is turned off, the data write device is turned on, and hence a data signal is written to the gate electrode of the drive transistor; and a light-emitting stage, in which the drive transistor generates a drive current to drive the light-emitting element to emit light.
