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.
