Abstract
The present application discloses a shift-register circuit used as a shift-register unit of current stage including a control sub-circuit coupled to a shift-register unit of previous stage and configured to recharge a pull-up node of the shift-register unit of previous stage during a touch-control operation performed after a gate line scanning of previous stage ends and before the gate line scanning of current stage starts. The control sub-circuit is further configured to compensate an internal voltage of the shift-register unit of previous stage before the touch-control operation ends so that the shift-register unit of previous stage is triggered to perform the gate line scanning of previous stage followed by the shift-register unit of current stage to perform the gate line scanning of current stage.
