Title:
SHIFT REGISTER, GATE DRIVER CIRCUIT, ARRAY SUBSTRATE
Document Type and Number:
WIPO Patent Application WO/2017/185822
Kind Code:
A1
Abstract:
A shift register, a gate driver circuit comprising the shift register, and an array substrate comprising the gate driver circuit. The shift register comprises a buffer discharging unit, a maintaining unit, an output unit, a pull-down unit, a charging unit, an input end (INPUT), a reset end (RESET), a first clock signal end (CLK), a second clock signal end (CLKB), a constant voltage end (VSS), and an output end (OUTPUT). The buffer discharging unit controls, according to a signal of the input end (INPUT), a signal of the reset end (RESET), and the level of a pull-down node (PD), whether to transmit a signal of the constant voltage end (VSS) to the output end (OUTPUT), and whether to transmit the signals of the constant voltage end (VSS) and the second clock signal (CLKB) to a pull-up node (PU). The maintaining unit controls the level of the pull-down node (PD) according to the signal of the second clock signal end (CLKB) and the level of the pull-up node (PU). The output unit controls, according to the level of the pull-up node (PU), whether to transmit a signal of the first clock signal end (CLK) to the output end (OUTPUT). The pull-down unit controls, according to the signal of the second clock signal end (CLKB), whether to transmit the signal of the fixed voltage end (VSS) to the output end (OUTPUT). The charging unit maintains the level of the output end (OUTPUT).
