ABSTRACT:
A driving method in accordance with the present invention permits the simple time sharing driving of a ferroelectric liquid crystal matrix panel at high scanning frequency and high multiplexing ratio. A predetermined pulse is applied to a scanning electrode when another scanning electrode is selected to reset the pixel. The pixel is inverted or kept by the action of a pulse applied to the pixel when selected and, under this condition, a desired brightness is written in a short scanning period. Besides, the representation of a number of grey levels is obtained by multiple scanning at reset timing varying with the scanning.
