| 20080284701 | METHOD FOR DRIVING LIQUID CRYSTAL DISPLAY - A method for driving a liquid crystal display is provided. The method includes: turning on a display-enable switch to pass through time of liquid crystal response and light display of a first frame until a reset time appeared. At the same time, turn on a second write-enable switch to pre-deliver a pixel signal corresponding to a second frame to a second storage capacitor. During reset time of the first frame time, turn on a reset switch and provide a reset voltage signal to a pixel electrode while the first and the second display-enable switches and the first and the second write-enable switches are turned off, in which the reset voltage signal has a first voltage level during a first period, and a second voltage level in a second period. Therefore, the method can increase brightness of the display, and decrease image sticking effect thereof. | 11-20-2008 |
