Abstract

The invention discloses a gate drive circuit of a display panel, a display device and a gate drive method. The gate drive circuit comprises an input module, a shift register module, a multi-level high-level signal generation module, a level conversion module and an output module. The multi-level high-level signal generation module respectively receives the high-level selection signal and at leasttwo preset level voltages, and generates and outputs a level voltage signal; the level conversion module performs level conversion according to the level voltage signal of the multi-level high-level signal generation module to generate a gate drive signal; and the gate drive signal is output to each gate line corresponding to the display panel. Level voltage signals with different high-level levelvoltages are selectively generated through the multi-level high-level signal generation module, the level conversion module takes the level voltage signals with a plurality of high-level level voltages as a level conversion reference, and gate driving signals with at least two high-level levels can be generated for the same gate line.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to a gate drive circuit of a display panel, a display device and a gate drive method. Background technique [0002] TFT-LCD (Thin Film Transistor Liquid Crystal Display, Thin Film Transistor Liquid Crystal Display) is one of the main varieties of flat panel display, and has become an important display platform in modern IT and video products. Generally, a liquid crystal display device controls light transmittance of liquid crystals through an electric field, thereby displaying images. The display device includes a display panel, and a source driving circuit and a gate driving circuit for driving the display panel. The source driving circuit provides data driving signals for the data lines of the display panel; and the gate driving circuit respectively provides gate driving signals for the gate lines of the display panel. [0003] Existing gate drive circuits usually...
