    (54) Display device and driving system thereof


    (57) A display device, which takes a specified period to rewrite the picture elements in one horizontal scanning period, comprises M pcs. of scanning lines divided into a plurality of groups each containing K pcs. of scanning lines (K > 1, M > 1, K, M: positive integers) and elements for supplying scanning signals to the M pcs. of scanning lines to rewrite an image. The scanning signal-supplying elements output scanning signal 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 pcs. of scanĀ­ning lines are rewritten by K times of scanning.
