Abstract

A shift register unit and its driving method, a gate drive circuit, and an array substrate, wherein the shift register unit includes: an input subcircuit connected between a signal input terminal and a pull-up node, configured to input to the pull-up node Signal; the output subcircuit is connected between the pull-up node and the signal output terminal, and is configured to output a pulse signal to the signal output terminal under the control of the pull-up node; the reset subcircuit is connected between the reset terminal, the pull-up node and the signal output terminal. Between the signal output terminals, it is configured to reset the pull-up node and the signal output terminal under the control of the reset terminal; and a clock signal selection subcircuit, the input terminal of which is connected to the first clock signal terminal and the second clock signal terminal, The first output terminal is connected to the output sub-circuit and is configured to select whether to provide the first clock signal or the second clock signal to the output sub-circuit according to the levels of the first control terminal and the second control terminal. In this way, the display panel can be freely switched between two different display modes of 2D and 3D, and simultaneous scanning of double gate lines can be realized in 3D display.

Description

technical field [0001] The present disclosure relates to the field of display technology, in particular to a shift register unit, a gate drive circuit including a multi-stage shift register and a drive method thereof. Background technique [0002] During the display process of a liquid crystal display panel including a pixel array, a gate driving circuit is used to generate gate line voltages for driving pixels on the display panel. The gate line voltage is output through the gate drive circuit, and each pixel is scanned row by row. In recent years, with the continuous improvement of the amorphous silicon thin film technology, the gate driver circuit can be integrated on the thin film transistor array substrate to form a GOA (Gate driver On Array) to drive the gate lines. The GOA driver is used to directly make the GOA unit on the liquid crystal panel, which can simplify the process, reduce the cost, and easily realize the narrow frame. [0003] Generally, a GOA composed o...
