Abstract

The embodiments of the present disclosure relate to a shift registers unit and a driving method thereof, and a gate driving device. The shift register unit includes a first and second input circuit, a pull-down control circuit, an output circuit, a pull-down circuit, and a control circuit. The first input circuit provides a first control signal to a pull-up node. The second input circuit provides a second control signal to the pull-up node. The pull-down control circuit provides the voltage of a first voltage terminal to a pull-down node, or controls the voltage of the pull-down node. The output circuit provides a second clock signal to a signal output terminal. The pull-down circuit provides the voltage of the first voltage terminal to the pull-up node and the signal output terminal. The control circuit provides the first input signal to the pull-up node.

Description

technical field [0001] The present invention relates to the field of display control technology, in particular to an array substrate gate drive circuit, a touch display device and a touch electronic device. Background technique [0002] Display panel with Touch (touch) function, Display (display) and Touch are time-division multiplexed. After the Touch is over, the GOA (Gate Driver on Array, array substrate gate drive) of the level that needs to be started remains at a high level during the Touch phase PU (Pull Up, pull-up) node, because the PU node will leak electricity, causing the Touch After the end, the level of the PU node of the GOA that needs to be started is low, so the TFT (Thin Film Transistor, Thin Film Transistor) in the pixel area is insufficiently charged, which affects the display touch effect. Contents of the invention [0003] This application is based on the inventor's understanding and research on the following issues: [0004] The GOA circuit of 8T2C...
