  • Ferroelectric liquid crystal display device and driving system thereof for driving the display by an integrated scanning method
    Patent number: 5298913
    Abstract: A ferroelectric liquid crystal display device is disclosed, which takes a specified period to rewrite the picture elements in one horizontal scanning period, and includes M scanning lines divided into a plurality of groups each containing K scanning lines (K>1, M>1, K, M: positive integers) and elements for supplying scanning signals to the M scanning lines to rewrite an image. The scanning signal-supplying elements output scanning signals to the first scanning line of each group in the first frame, to the second scanning line of each group in the second frame, and to the Kth scanning line of each group in the Kth frame so that the M scanning lines are rewritten by K times of scanning.
