Title:
SHIFT REGISTER UNIT, GATE DRIVER CIRCUIT, AND DRIVING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/041827
Kind Code:
A1
Abstract:
A shift register unit for a gate driver circuit (GOA), a gate driver circuit comprising the shift register unit, and a driving method applied to the shift register unit. The shift register unit comprises: an input sub-circuit (110), configured to output an input signal to a first node (PH); a pull-up control sub-circuit (120), configured to charge a pull-up node (PU) by means of a first power end (VDD) under the control of a potential of the first node (PH); an output sub-circuit (130), configured to output a clock signal of a clock signal end (CLK) to an output end under the control of the potential of the pull-up node (PU); and a first touch control sub-circuit (140), a first end of which is connected to a touch holding signal end, a second end is connected to the pull-up node (PU), a third end is connected to the output end, and a fourth end is connected to a second power end (VGL), and which is configured to pull down levels of the pull-up node (PU) and the output end to a second potential by means of the second power end (VGL) under the control of the touch holding signal of the touch holding signal end.
