摘要： A method for driving an active matrix liquid crystal display (LCD) (200) includes: dividing a frame time into a first period and a second period; defining a gradation voltage that makes the light transmission of a pixel unit accumulated in the first period correspond to image data of an external circuit; defining a black-inserting voltage which corresponds with a black image; applying the gradation voltage to pixel electrodes (203) of pixel units of the LCD when the gate lines (201) are scanned by a gate driver (210) of the LCD in the first period; applying the black-inserting voltage to the pixel electrodes of the pixel units when the gate lines are scanned by the gate driver in the second period; and turning off a backlight of the LCD in the second period.

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.
