Title:
SHIFT REGISTER UNIT, DRIVING METHOD THEREFOR, GATE DRIVER CIRCUIT AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/000945
Kind Code:
A1
Abstract:
A shift register unit, driving method therefor, gate driver circuit and display device, the shift register unit comprising: an input module (1), a reset module (2), a control module (3), a pull-down module (4) and an output module (5); a first control terminal (5a) of the output module (5) is connected to a first node (P1), a first input terminal (5b) thereof is connected to a second clock signal terminal (CLK), and a first output terminal (5c) is connected to a signal output terminal (Output); both ends (4a, 4b) of the pull-down module (4) are respectively connected to a first clock signal terminal (CLKB) and the first node (P1); the pull-down module (4) can lower the potential of the first node (P1) by means of the first clock signal terminal (CLKB), so as to prevent a signal meant for the second clock signal terminal (CLK) from being provided to the signal output terminal (Output) by mistake, which is caused by the potential of the first node (P1) rising along with the potential of the second clock signal terminal (CLK), which then in turn causes various display failures.
