Abstract

The present application discloses a shift-register circuit including a shift-register unit and a shutdown-discharge sub-circuit. The shift-register unit is coupled to a clock port, a first reference voltage port, a second reference voltage port, and an output port and configured to set a voltage level at a pull-up node to control a clock signal from the clock port being outputted to the output port to drive a display panel during a display period. The shutdown discharge sub-circuit is configured to at least simultaneously receive at least one shutdown signal at a first voltage level from a shutdown-discharge control port and a second signal at the first voltage level from the second reference voltage port to start a shutdown period to discharge at least one of the pull-up node and the output port.
