[0035] In the prior art, the input terminals of the array substrate row drive modules with a set number of stages receive the same pull-up control signal. Since there is a time overlap between the high potential signal output by the gate and the high potential of the pull-up control signal, the array substrate row drive circuit Under the environment of high temperature operation, the potential of the Q node will be affected, resulting in the abnormal output waveform of the set number of stages and the abnormal panel display.

[0036] Based on this, this embodiment provides an array substrate row driving circuit, including: a multi-stage array substrate row driving module and a plurality of thin film transistors. Receive different pull-up control signals and output corresponding gate signals;

Abstract

The invention discloses an array substrate row drive circuit and a drive method of the array substrate row drive circuit. The array substrate row drive circuit comprises a plurality of levels of array substrate row drive modules and a plurality of thin film transistors, wherein the input ends of the array substrate row drive modules with the set level number receive different upwards pulling control signals through the corresponding thin film transistors and output corresponding grid signals; for each of the array substrate row drive modules with the set level number, the falling edge of the upwards pulling control signals received by the input end of the array substrate row drive module is level with the rising edge of the grid signals output by the input end of the array substrate row drive module. With the adoption of the scheme, the circuit and the method have the advantages that the overlapping in time of the upwards pulling control signals received by the input ends of the array substrate row drive modules with the set level number and the grid signals output by the input ends of the array substrate row drive modules with the set level number can be avoided, so that the Q node electric potential is not influenced when the array substrate row drive circuit is in the high-temperature operation environment, and then a liquid crystal display panel can be normally used in the high-temperature operation environment.
