US Patent 7643021 Driving system and driving method for motion picture display

A driving system and a driving method for motion pictures are described, using an input, a black image insertion module, an advanced overdrive module, and a partial frame rate control module. The input receives a first frame and a second frame in order. The black image insertion module inserts a single fixed gray level frame between the first frame and the second frame. The advanced overdrive module increases the second frame to (n+a) bits and converts the same to the overdrive image, in which the first frame and the second frame are n bits. The partial frame rate control module smoothes the overdrive image and converts the same to an output image to refresh the pixels from the single fixed gray level frame to the second frame.
