Liquid crystal apparatus |
摘要 |
Driving apparatus including scanning electrodes and data electrodes, a liquid crystal assuming first and second optical states according to the polarity of a writing voltage applied thereto and disposed between the scanning and data electrodes, scanning-side and drive-side drivers, and a controller for controlling these drivers. The scanning-side drive supplies first and second scanning selections signals having mutually different voltage wave forms to the scanning electrodes so that the first and second scanning selection signals are applied alternately in respective vertical scanning periods. The data-side driver supplies data pulses to the data electrodes in synchronism with the first and second scanning selection signals so as to form one picture in at least four vertical scanning periods. The controller controls the scanning-side and data-side drivers so as to scroll each picture in at least four vertical scanning periods.
