Abstract
The present invention provides a method for speeding up rotation of liquid crystal molecule and a liquid crystal panel drive circuit used in the method. The method includes providing a liquid crystal display device, which includes a glass substrate having a liquid crystal panel drive circuit formed thereon and including a timing controller and pixel units each including a thin-film transistor, a common electrode, a pixel electrode electrically connected to the thin-film transistor, a compensation unit, and a storage capacitor, the compensation unit including a compensation capacitor, the timing controller being electrically connected to the compensation unit and the pixel electrode; calculating discharging/charging time of the compensation capacitor; activating the liquid crystal display device, where the source driver applies a drive voltage via the thin-film transistor to the pixel electrode; and the timing controller controlling the compensation unit to conduct on or cut off according to the drive voltage.
