Abstract

The invention discloses a gate drive circuit and its drive circuit unit. The drive circuit unit is used to output a drive signal and includes an input unit, an auxiliary output unit and an output unit. The input unit is coupled to an input node and receives a start signal to make the input node have a potential. The auxiliary output unit receives a first timing signal to increase the potential of the input node. The output unit receives a second timing signal to further increase the potential of the input node, and outputs a driving signal.

Description

technical field

[0001] The present invention relates to a gate drive circuit and its drive circuit unit, and in particular to a gate drive circuit and its drive circuit unit in a liquid crystal display device. Background technique

[0002] In a general liquid crystal display device, a gate driver is usually used to output a gate driving signal to drive the scanning lines in the liquid crystal display device. However, since the cost of using the gate driver is too high, how to reduce the cost of the gate driver is very important.

[0003] A known method is to fabricate a gate driving circuit on a glass substrate, and use the gate driving circuit to output gate driving signals to scan lines, thereby replacing the original gate driver and reducing manufacturing costs. Please refer to figure 1 , shows a schematic diagram of a general gate drive circuit. The gate drive circuit 100 includes a plurality of drive circuit units 102, and is controlled by a voltage source VSS and ti...
