Abstract
The invention discloses a liquid crystal driving method and apparatus for black frame insertion of an image, and a liquid crystal display device. The method includes, in a black frame insertion period after the frame period ends, sending, by a timing controller, a row of black image data to a register of a source driver; and in the black frame insertion period, maintaining, by the register, the row of black image data being output until the black frame insertion period ends, so as to enable the row of black image data to refresh each row of liquid crystal cells. Accordingly, the complexity of driving processes and the data calculations in the black frame insertion are greatly reduced.
