Title:
A SHIFT-REGISTER CIRCUIT, GATE DRIVE CIRCUIT, LIQUID CRYSTAL DISPLAY AND TOUCH PANEL
Document Type and Number:
WIPO Patent Application WO/2019/010952
Kind Code:
A1
Abstract:
A shift-register circuit, a driving method thereof, a gate-driving circuit and a display apparatus are disclosed. The shift-register circuit includes an input sub-circuit (10), a reset sub-circuit (20), an output sub-circuit (30), a pull-down control sub-circuit (40), and a pull-down sub-circuit (50). The pull-down control sub-circuit (40) is configured, after an output period of an operation cycle for displaying one frame of image, to control the pull-down node (PD) at a first voltage level to keep voltage level low at an output port (OUT). Additionally, the pull-down sub-circuit (50) is configured, under control of power signals, to pull down the voltage level at the output port (OUT). For the display-touch panel with full-in-cell touch sensors, the voltage level at output port (OUT) can be effectively reduced to avoid mutual interference between drive signals and touch-control signals.
