Abstract:
A liquid crystal device comprising:a plurality of strobe electrodes;a plurality of data electrodes;a plurality of liquid crystal picture elements formed at intersections between the data electrodes and the strobe electrodes; anda strobe signal generator arranged to supply N strobe signals sequentially to groups of N strobe electrodes, where N is an integer greater than one and the N strobe signals are supplied simultaneously to the strobe electrodes of each group,wherein a data signal generator is arranged to supply any selected one of a plurality of different data signals to each of the data electrodes in synchronism with the strobe signals, andwherein each of the N strobe signals comprises a strobe pulse and a prepulse period during which the strobe signal has an amplitude less than half the maximum amplitude thereof and wherein the prepulse periods of the N strobe signals are different from each other.
