Abstract
An active matrix liquid crystal device is driven by sequentially applying a first scanning pulse to reset each pixel on a first selected line, a second scanning pulse to write each pixel on a second selected line and a third scanning pulse to provide a voltage signal which is equal to or less than the optical threshold value of the liquid crystal to each pixel on a third selected line. According to the driving method, the first, second and third selected lines are spaced at a predetermined number of lines from each other, and a sum of time integrated values of the applied voltage signals is or approaches zero.
