Claim:
1. A liquid crystal driving method for black frame insertion of an image, applied to a liquid crystal display (LCD) device, wherein during an image driving process, a frame period and a black frame insertion period are alternately next to each other, and the method comprises the steps of: in a black frame insertion period after the frame period ends, sending, by a timing controller, only one row of black image data to a register of a source driver to perform a gray scale voltage conversion calculation only once; and in the black frame insertion period, maintaining, by the register, the only one row of black image data being output from the register until the black frame insertion period ends, so as to enable the only one row of black image data to refresh each row of liquid crystal cells sequentially from a first row to a final row of the liquid crystal cells.
