Abstract:
1. A driving method for rapidly charging pixels of a liquid crystal display, wherein the liquid crystal display comprises a plurality of data lines, a plurality of scan lines, at least one common electrode, and a plurality of pixel units corresponding to sets of the interlacing data lines and scan lines, and each of the pixel units comprises a TFT having a gate coupled to the corresponding scan line, a first electrode coupled to the corresponding data line, and a second electrode, a storage capacitor having a terminal coupled to the second electrode, and a liquid crystal cell coupled between the second electrode and the common electrode, the method comprising the steps of: providing a plurality of storage electrodes, each corresponding to one of the scan lines and coupled to the other terminal of the storage capacitor; sequentially generating a plurality of pre-charging signals, respectively output to the storage electrodes, wherein the pre-charging signals vary periodically; and sequentially generating a plurality of scan signals, respectively output to the scan lines; wherein a variation in a voltage level of each of the pre-charging signals occurs before one of the scan signals is applied to the corresponding scan line.
