Abstract
The present invention proposes a gate driver which simplifies a circuit structure by effectively compounding the pull-down holding circuit and signals to achieve a design for ultra-narrow bezel gate driver. In addition, It effectively lessens voltage offset at the second node and prolongs GOA circuit operating time to prolongs lifetime of the LCD when the seventh transistor of the first pull-down holding circuit adopts equivalent diode connection. At last, it reduces RC delay to efficiently lower power-consumption to more effectively decrease LCD energy-consumption when amount of transistors and signals of the first and the second pull-down holding circuits decreases.
