Description
technical field [0001] The invention relates to a liquid crystal display device and a driving method thereof. Background technique [0002] In a thin film transistor liquid crystal display device, image display is realized by changing the electric field applied to each pixel to change the twist angle of the liquid crystal molecules corresponding to the pixel, thereby controlling the amount of light passing through. If a direct current (DC) signal is used to drive the liquid crystal molecules, the liquid crystal molecules will be deflected in one direction. After a period of time, the physical properties of the liquid crystal molecules will be destroyed due to being in a certain direction continuously, and the liquid crystal molecules cannot be corrected according to the electric field applied to them. Rotate to form grayscale. Therefore, most thin film transistor liquid crystal display devices use an alternating current (AC) signal to reversely drive the liquid crystal mole...
