Abstract
本发明公开了一种栅极驱动电路、栅极电压调节方法以及液晶显示器。栅极驱动电路包括开启电压输出模块和关闭电压输出模块,开启电压输出模块和关闭电压输出模块分别与栅线连接,开启电压输出模块输出到栅线的开启电压以及关闭电压输出模块输出到栅线的关闭电压均为可调的。本发明通过对栅极驱动电路中的开启电压输出模块输出的开启电压以及关闭电压输出模块输出的关闭电压进行调节,使得存在Mura不良的液晶面板的显示画面尽可能地均匀,从而提高存在Mura不良的液晶面板的画面显示品质。
The invention discloses a grid drive circuit, a grid voltage regulation method and a liquid crystal display. The gate drive circuit includes a turn-on voltage output module and a turn-off voltage output module, the turn-on voltage output module and the turn-off voltage output module are respectively connected to the gate line, the turn-on voltage output by the turn-on voltage output module to the gate line and the turn-on voltage output by the turn-off voltage output module to the gate line The shutdown voltage is adjustable. The present invention adjusts the turn-on voltage output by the turn-on voltage output module in the gate drive circuit and the turn-off voltage output by the turn-off voltage output module, so that the display screen of the liquid crystal panel with mura defect is as uniform as possible, thereby improving the quality of the mura defect. The screen display quality of the LCD panel.
