Gate drive circuit, array substrate and display device

Abstract

The invention relates to the field of display technologies, in particular to a gate drive circuit, an array substrate and a display device. Based on the prior art, an output end switching element controlled by second clock signals is additionally arranged between the input end and the output end of a shifting register in each level, and the original reset connection mode between the output end of the next level and the reset end of the upper level is changed to be the reset connection mode between the output end of the N+2 level and the reset end of the N level. Under the design, gate line output signals of the shifting register in each level in the gate drive circuit can be output in advance, the continuous output time of the gate line output signals is doubled, so that write time of data signals is greatly increased, and occurring possibility of display failures is reduced.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a gate drive circuit, an array substrate and a display device. Background technique [0002] Thin film transistor liquid crystal display (TFT-LCD for short) is one of most liquid crystal display screens, which adopts thin film transistor technology, which can significantly improve image quality. [0003] As an important part of the TFT-LCD driver, the main function of the gate drive circuit is to convert the input clock signal through the shift register and add it to the gate line of the liquid crystal display panel. In the multi-stage shift register of the gate driving circuit, each stage is connected to a corresponding gate line to output a gate line driving signal. In the gate drive circuit, the shift registers at all levels are connected to each other, the start signal is input to the first level of each level, and the gate line drive signals are output to the gate ...

Problems solved by technology

[0005] However, since the resolution of the current liquid crystal display is getting higher and higher, the writing time of the data signal when the gate line signal is output is getting shorter and shorter.

If the gate line drive circuit in the prior art is also used, it is easy to cause abnormal display of the picture due to insufficient writing time of the data signal, so that the high-resolution liquid crystal display is prone to display failure, which cannot meet the user's requirements for display effect.
