摘要： An optical modulation apparatus has a matrix electrode arrangement comprising scanning electrodes and signal electrodes oppositely spaced from the scanning electrodes. Scanning signals are selectively applied sequentially and periodically to the scanning electrodes and information signals are selectively applied to the signal electrodes in synchronism with the scanning signals to effect optical modulation of an optical modulation material showing a first stable state and a second stable state with respect to an electric field applied thereto interposed between the scanning and signal electrodes. Before or after an information signal is applied to a selected signal electrode in synchronism with a scanning signal applied to a selected scanning electrode, an auxiliary signal different from the information signal is applied to the selected signal electrode in synchronism with the scanning signal, and an amplitude of a writing voltage applied to an intersection of the selected scanning electrode and the selected signal electrode is two or more times that of a first non-writing voltage applied to an intersection of a non-selected scanning electrode and the selected signal electrode. The amplitudes of the writing voltage and the first non-writing voltage are respectively determined with respect to a reference voltage determined as a difference between a voltage applied to a signal electrode receiving no data signal, and a voltage applied to the non-selected scanning electrode.

摘要： A liquid crystal apparatus comprises a liquid crystal device including scanning electrodes and signal electrodes intersecting each other, and a chiral smectic liquid crystal disposed therebetween. The chiral smectic liquid crystal assumes a first orientation state when supplied with a pulse voltage of one polarity exceeding a first threshold voltage, a second orientation state when supplied with a pulse voltage of the other polarity exceeding a second threshold voltage, and a third orientation state when released from application of the pulse voltage of one or the other polarity. Drive means periodically applies the scanning selection signal to the scanning electrodes, and controls the application of the scanning selection signal, the scanning non-selection signal and the data signals so as to apply the data signals in synchronism with the scanning selection signal, thereby applying the pulse voltage of one or the other polarity as a combination of the information signal and the one or the other voltage signal of the scanning selection signal to the chiral smectic liquid crystal. Drive means also applies an auxiliary signal in combination with the scanning non-selection signal to suppress a change into the third orientation state of the chiral smectic liquid crystal.

摘要： A driving method for an optical modulation device is applicable to driving of an optical modulation device, e.g. a liquid crystal device having a matrix electrode arrangement comprising a group of scanning electrodes, a group of signal electrodes oppositely spaced from the group of scanning electrodes, and an optical modulation material (e.g. a liquid crystal) showing histability with respect to an electric field applied thereto disposed between the groups of scanning electrodes and signal electrodes. The driving method is featured by applying a voltage allowing the liquid crystal having histability to be oriented to a first stable state (one optically stable state) between a selected scanning electrode of the group of scanning electrodes and a selected signal electrode of the group of signal electrodes, and by applying a voltage allowing the liquid crystal having histability to be oriented to a second stable state (the other optically stable state) between the selected scanning electrodes and non-selected signal electrodes.
