Title: SHIFT REGISTER UNIT CIRCUIT AND DRIVING METHOD, SHIFT REGISTER, GATE DRIVE CIRCUIT, AND DISPLAY APPARATUS
Abstract:
A shift register unit circuit includes an input sub-circuit (100), a pull-up sub-circuit (200), a pull-down control sub-circuit (400), a pull-down sub-circuit (300), and a voltage regulating sub-circuit (600). The input sub-circuit (100) receives an input signal from a signal input terminal (IN) to control a potential of a pull-up node (PU). The pull-up sub-circuit (200) outputs a gate driving signal to an output terminal (OUT) under control of the potential of the pull-up node (PU) and a signal from a first signal terminal (CLK2). The pull-down control sub-circuit (400) conducts a pull-down node (PD) with a first node (FIRST) under control of a signal from the second signal terminal (CLK1). The pull-down sub-circuit (300) conducts the pull-up node (PU) with the first node (FIRST) and the turn-down signal terminal (VSS) with the output terminal (OUT) under control of a potential of the pull-down node (PD). The voltage regulating sub-circuit (600) conducts the first node (FIRST) with the turn-down signal terminal (VSS) under control of a potential of the first node (FIRST).
