Method of driving optical switch element.

摘要

In a driving method of an optical switch element for controlling a quantity of transmission light between opposed electrodes by interposing a transparent, high dielectric material (4) between the opposed electrodes (6a, 6b) and applying a positive or negative voltage between the opposed electrodes, (by changing over a switch 13 from a terminal a to terminal b or terminal c) the improvement wherein a period in which the opposed electrodes are substantially short-circuited is disposed in order to make it possible to either reduce or eliminate stored charge.

This method can be applied in a printer using the optical switch element.
