Description

technical field [0001] The invention relates to a liquid crystal display device and a driving method thereof. Background technique [0002] Liquid crystal display devices have been widely used in electronic equipment such as personal computers due to their advantages of thinness, lightness, high brightness, and low radiation. However, at the moment of power-on, the transmitted working signal is unstable, which will interfere with the liquid crystal display device, thereby causing adverse phenomena such as power-on noise. [0003] see figure 1 , is a schematic diagram of the circuit structure of a prior art liquid crystal display device. The LCD device 1 includes a power supply circuit 11 , a panel power supply circuit 12 , a drive control circuit 13 , a data drive circuit 14 , a scan drive circuit 15 and a display panel 16 . Wherein, the display panel 16 includes a plurality of pixel units (not shown), and each pixel unit includes a thin film transistor (not shown) and a ...
