  • Patent number: 11244593
    Abstract: The present application discloses a shift-register circuit configured as one of a plurality of shift-register units cascaded in series. The shift-register circuit includes a pull-up sub-circuit coupled to a pull-up node, a first clock port, and an output port. The pull-up sub-circuit is configured to pass a first clock signal from the first clock port to the output port when the pull-up node is set to a turn-on voltage. Additionally, the shift-register circuit includes a chamfering sub-circuit coupled to the pull-up node, the first clock port, a chamfering clock port, and the output port. The chamfering sub-circuit is configured to pass a chamfering clock signal from the chamfering clock port to the output port. The chamfering clock signal is at the turn-on voltage simultaneously with the first clock signal and becomes a turn-off voltage slightly earlier in time than the first clock signal.
