Abstract

The application provides a shift register, a gate drive circuit and a display control method. The shift register includes: a first input module, a latch module, and a first output control module; the control terminal, the first terminal, and the second terminal of the first input module are respectively connected to the first gate voltage signal terminal and the first latch The signal end and the pull-up node are electrically connected; the first control end, the second control end, the first end, and the second end of the latch module are respectively connected to the pull-up node, the pull-down node, the first adjustment signal end, and the second adjustment The signal terminal is electrically connected; the control terminal, the first terminal, and the second terminal of the first output control module are respectively electrically connected to the pull-up node, the clock signal terminal, and the output terminal; the technical solution of the application is easier to realize the pull-up node in the display stage The potential is stable, so as to ensure the stability of the grid voltage signal output by the first output control module, and reduce the phenomenon of poor LHB stripes and poor split screens.

Description

technical field [0001] The present application relates to the technical field of liquid crystal display, and in particular, the present application relates to a shift register, a gate driving circuit and a display control method. Background technique [0002] At present, the GOA (Gate Driver On Array, array substrate gate driver) driver circuit in TDDI (Touch and Display Driver Integration) products mainly adopts the 10T2C circuit model, that is, 10 TFT (Thin Film Transistor-Liquid, thin film transistor) and the circuit model formed by 2 capacitors. In this circuit model, the potential of the pull-up node is mainly maintained by the capacitor. When the leakage of some TFTs is large, the potential of the pull-up node is not easy to maintain in the display stage, the output signal is unstable, and LHB (Long Horizon Blanking, long Horizontal blank area) bad horizontal stripes, when the leakage is more serious, there will also be a phenomenon of poor split screen, which serious...
