Patent ID: 11200861

Abstract:
A shift register unit includes a pull-down sustaining sub-circuit and a pull-down sub-circuit. The pull-down sustaining sub-circuit includes: a first transistor having a control electrode configured to input a pull-down sustaining signal, a first electrode connected to a first power signal terminal, and a second electrode connected to a pull-down node; a first capacitor; and a second transistor having a control electrode connected to an input signal terminal. The pull-down sub-circuit includes: a third transistor having a control electrode connected to the first terminal of the first capacitor, a first electrode connected to a pull-up node, and a second electrode connected to the second power signal terminal; a fourth transistor having a control electrode connected to the first terminal of the first capacitor, a first electrode connected to an output sub-circuit, and a second electrode connected to the second power signal terminal.
