  • Publication number: 20220036788
    Abstract: A shift register includes an output sub-circuit and a coupling sub-circuit. The output sub-circuit is coupled to a second clock signal terminal, a pull-up node and a signal output terminal. The output sub-circuit is configured to output a second clock signal received at the second clock signal terminal to the signal output terminal under a control of a voltage of the pull-up node. The coupling sub-circuit is coupled to the second clock signal terminal and a pull-down node. The coupling sub-circuit is configured to couple a voltage of the pull-down node through the second clock signal received at the second clock signal terminal.
