SHIFT REGISTER UNIT, DRIVING METHOD, GATE DRIVING CIRCUIT, AND DISPLAY DEVICE

WIPO Patent Application WO/2021/184899

A1

A shift register unit, a driving method, a gate driving circuit, and a display device. The shift register unit comprises a pull-down node control circuit (10); the pull-down node control circuit (10) is electrically connected to an input end (I1), a reset end (R1), a first voltage end (V1), a second voltage end (V2), and a pull-down node (P2), respectively, and is used for controlling the pull-down node (P2) to be communicated with the first voltage end (V1) or the second voltage end (V2) under the control of an input signal provided by the input end (I1) and a reset signal provided by the reset end (R1), and controlling and maintaining the potential of the pull-down node (P2). According to the shift register unit, the number of used transistors is reduced, and the reliability is high.
