摘要： A driving method for an active matrix liquid crystal display panel includes the following steps. First, a frame period is divided into a display period (t1) and a black insertion period (tr). A gray-scale voltage is generated according to a desired corresponding light transmittance of each pixel of the liquid crystal display panel; and during the display period, the gray-scale voltage is supplied to a corresponding pixel electrode of the liquid crystal display panel. Then during the black insertion period, a restoring voltage Vh is supplied to the pixel electrode, so that the pixel is returned to an initial black state. Accordingly, the quality of motion pictures of the liquid crystal display panel is good.
