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

Document Type and Number:

WIPO Patent Application WO/2018/161565

Kind Code:

A1

Abstract:

A shift register unit (1000,2000,3000) includes an input circuit (100), an output circuit (200), a pull-down control circuit (300), and a pull-down circuit (400). The pull-down control circuit (300) is coupled to a first power supply signal terminal (VGH), a second power supply signal terminal (VGL), a pull-up node (PU), a pull-down node (PD), and a reset signal terminal (RST). The pull-down control circuit (300) is configured to transmit a first power supply signal from the first power supply signal terminal (VGH) to the pull-down node (PD) under a control of the first power supply signal, transmit the first power supply signal from the first power supply signal terminal (VGH) to the pull-down node (PD) under a control of the reset signal (RST), and transmit a second power supply signal from the second power supply signal terminal (VGL) to the pull-down node (PD) under a control of the pull-up node (PU).
