Gate drive circuit and array substrate

Abstract

An embodiment of the invention discloses a gate drive circuit and an array substrate, relates to the technical field of display, and can guarantee normal working of other gate drive units when faults such as a short circuit and the like happen to an input access of a clock signal of a certain gate drive unit. The gate drive circuit comprises a plurality of gate drive unit groups, wherein each gate drive unit group comprises m gate drive units, wherein m is an integer lager than 1; each gate drive unit group outputs a gate drive signal to a same gate line; and when a fault happens to one gate drive unit in the gate drive unit groups, the failed gate drive unit stops working, and other gate drive units maintain the working of the gate drive unit groups.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a gate drive circuit and an array substrate. Background technique [0002] In recent years, the development of liquid crystal displays has shown a trend of high integration and low cost. One of the very important technologies is the realization of mass production of Gate Driver on Array (GOA for short) technology. The GOA technology is used to integrate the gate drive circuit on the array substrate of the liquid crystal display panel, so that the original integrated gate drive circuit can be saved, so as to reduce the product cost in terms of material cost and manufacturing process. The gate driving circuit integrated on the array substrate using GOA technology is also called a GOA circuit. [0003] In the prior art, the GOA circuit includes several GOA units. Each GOA unit is connected to a pair of anti-phase clock signals, and outputs a gate line signal corresponding...

Problems solved by technology

[0003] In the prior art, the GOA circuit includes several GOA units. Each GOA unit is connected to a pair of inverted clock signals, and outputs a gate line signal corresponding to drive a gate line. Specifically, the output terminal of each GOA unit is connected to a Gate line; the inventors found that because the GOA unit is connected to a pair of anti-phase clock signals at the same time, the input paths of this pair of anti-phase clock signals are usually very close to or even overlap, similar to capacitors, and this pair of anti-phase clock signals The voltage difference between the signals can reach 20 volts, and the high voltage will easily cause the similar capacitance formed between the input channels of the inverted clock signal to be broken down, so that the input channel of the inverted clock signal will be short-circuited, and the short-circuited GOA unit Abnormal operation, which may lead to abnormal operation of all GOA units, and even abnormal operation of integrated circuits inside the LCD display
