Abstract
This invention is directed to an improved liquid crystal video display device. An interlacing video display technique is utilized and scanning signals are provided to every other scanning electrode line in sequential order, shifting selected lines every frame. An additional selected voltage is provided during the time period which overlaps the selected scanning electrode lines to the adjacent non-selected electrodes both above and below the selected scanning electrode lines. According to the invention, a high resolution display is provided while reducing associated flicker by driving all scanning lines in the desired order.
