摘要： A driving method is provided for driving an optical modulation device. The device has picture elements arranged in the form of a matrix consisting of a plurality of rows and a plurality of columns defined by the intersections of scanning electrodes and signal electrodes, and a liquid crystal having a memory function. The picture elements in each row are selectively supplied with either a voltage for orienting the liquid crystal to one display state, or another voltage for orienting the liquid crystal to another display state. The method comprises the steps of sequentially and repetitively applying a scanning selection signal to the scanning electrodes, the scanning selection signal comprising a former signal of a first voltage and a latter voltage signal of a second voltage different from the first voltage to one of the scanning electrodes to select a particular scanning electrode, and applying data signals to the signal electrodes, each data signal comprising an information signal for selecting a display state of a picture element on the particular scanning electrode. The picture elements on the particular scanning electrode supplied with the former voltage signal are non-selectively erased into an erased state and a picture element on the particular scanning electrode supplied with the latter voltage signal is placed in either the one display state or another display state depending on the information signal.

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 bistability with respect to an electric filed 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 bistability 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 bistability to be oriented to a second stable state (the other optically stable state) between the selected scanning electrodes and non-selected signal electrodes; or by applying a voltage allowing the optical modulation material having bistabity to be oriented to a first stable state between a selected scanning electrode and the group of signal electrodes, applying a voltage allowing the liquid crystal oriented to the first stable state to be oriented to a second stable state between the selected scanning electrode and a selected signal electrode, and applying a voltage set to a value between a threshold voltage -V.sub.th2 (for the second stable state) and a threshold voltage V.sub.th1 (for the first stable state) between non-selected scanning electrodes and the group of signal electrodes.
