ABSTRACT:
By using an auxiliary signal bringing a ferroelectric liquid crystal to an extreme transmission state in an active matrix it is impossible for successive charge compensation to occur on the pixels. This prevents the growth of regions where transmission occurs or does not occur and provides the possibility of obtaining gray scales in a reproducible manner.
