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 driving method for an optical modulation device comprising matrix picture elements each formed at intersecting points of scanning lines and data lines between which a bistable optical modulation material represented by a ferroelectric liquid crystal is interposed.
