Abstract

The invention provides a grid driving circuit, an array substrate and a display device. The grid driving circuit is used for sequentially inputting scanning signals to a plurality of grid lines line-by-line, the grid driving circuit comprises a plurality of driving units and waveform processing units which are arranged in a cascade connection mode and in one-to-one correspondence with the grid lines, the waveform processing units are arranged between the output ends of the driving units corresponding to the grid lines arranged on the even number lines and the grid lines, the waveform processing units are used for processing the waveforms of the output signals of the driving units corresponding to the grid lines into angle cutting weaves and take signals with the waveforms being angle cutting weaves as scanning signals to input the signals into the grid lines. The grid driving circuit can achieve equal charging voltages of sub-pixels of the even number lines and the sub-pixels of the odd number lines, and therefore the problem that cross stripes occur due to the fact that the grid driving circuit is driven by a two-point mode is solved, and therefore the quality of the array substrate and the display device is improved.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal display, and in particular relates to a gate drive circuit, an array substrate and a display device. Background technique [0002] GOA (Gate Driver On Array) technology concentrates the gate switching circuit on the array substrate, because it not only saves the part of the gate driver integrated circuit, but also saves the process of binding the integrated circuit, therefore, It is widely used in thin film transistor liquid crystal display (Thin Film Transistor Liquid Crystal Display, referred to as TFT LCD). [0003] figure 1 Circuit diagram for the existing GOA unit. see figure 1 , the GOA circuit has a plurality of GOA units, and each GOA unit has a positive clock input signal CLK, a reverse clock input signal CLKB, a low voltage signal VSS, and a high voltage signal VDD, wherein each GOA unit also has an input terminal INPUT , output terminal OUTPUT, reset terminal RESET, and the o...
