    • A method for driving an optical modulation device of a group of scanning electrodes and a group of signal electrodes arranged so that picture elements are defined at the intersections therebetween and a bistable optical modulation material assuming one of two stable states between the groups of electrodes, by in a first phase orienting the bistable material at the picture elements on an N-th scanning electrode to one stable state, and applying a writing signal to the signal electrodes in synchronism with a scanning signal to the N-th scanning electrode and while orienting the bistable material at the picture elements on an N+1-th scanning electrode to the one stable state. Also disclosed is a driving mode wherein a scanning signal is applied to the whole or a part of the scanning electrodes while, in phase therewith, a signal is applied to the whole or a part of the signal electrodes so that the optical modulation material is oriented to a first stable state, and a second step in which a scanning signal is applied to the whole or a part of the scanning electrodes while in phase therewith, a signal is applied to a selected signal electrode among the whole or a part of the signal electrodes so that the bistable optical modulation material is oriented to a second stable state.
    • 一种用于驱动一组扫描电极和一组信号电极的光调制装置的方法,其布置成使得在其间的交点处形成像素,并且假定电极组之间具有两种稳定状态之一的双稳态光调制材料,通过 在将第N扫描电极上的像素上的双稳态材料定向到一个稳定状态的第一阶段中,并且向与第N扫描电极的扫描信号同步地向信号电极施加写信号, 在第N + 1扫描电极上的像素处的双稳态材料到一个稳定状态。 还公开了一种驱动模式,其中将扫描信号施加到扫描电极的全部或一部分,同时与信号电极的全部或部分施加信号,使得光学调制材料取向 以及第二步骤,其中扫描信号与扫描电极的整个或一部分同时施加到扫描电极的整个或一部分中,在信号的全部或部分中将信号施加到所选择的信号电极 电极,使得双稳态光调制材料取向为第二稳定状态。
