Claim:
A driving method for a display, wherein the display comprises a plurality of scan lines and a plurality of signal lines, each of the scan lines and each of the signal lines are electrically connected to a corresponding pixel via a thin film transistor (TFT), a gate of the TFT is electrically connected to the corresponding scan line, a source of the TFT is electrically connected to the corresponding signal line, a drain of the TFT is electrically connected to a neighboring scan line neighboring to the corresponding scan line via a storage capacitor, the drain is also electrically connected to a common electrode via a pixel electrode of the pixel, and a voltage level of the common electrode is a common voltage value, the driving method comprising: applying a first pre-charge voltage and a first scan voltage sequentially to a scan line in a first duration; applying a second pre-charge voltage and a second scan voltage sequentially to the scan line in a second duration adjacent to the first duration, wherein the first pre-charge voltage makes a voltage level of the scan line change from a first voltage level to a second voltage level and then return to the first voltage level, and then the first scan voltage makes the voltage level of the scan line change from the first voltage level to a third voltage level and then return to the first voltage level, wherein the second pre-charge voltage makes the voltage level of the scan line change from the first voltage level to a fourth voltage level and then return to the first voltage level, and then the second scan voltage makes the voltage level of the scan line change from the first voltage level to the third voltage level and then return to the first voltage level, where the first, the second, the third and the fourth voltage levels are different from each other, wherein the first pre-charge voltage and the second pre-charge voltage are opposite in phase relative to the first voltage level, and the amplitudes of the pre-charge voltages are smaller than those of the scan voltages, wherein the pre-charge voltages are incapable of turning on the corresponding TFT, and make a voltage level of the pixel electrode of the pixel return back to or close to that of the common electrode, wherein the amplitude of the third voltage level is larger than that of the second voltage level, and a black frame insertion is performed when the voltage level of the pixel electrode of the pixel has returned back to or close to that of the common electrode, and a duration of the black frame insertion is about 30% of an interval time for displaying an entire frame by the display.
