Title: Driving method of optical switch element
Inventor: UMEDA TAKAO
IPC: G06K15/12
Filed: 1984-07-04
Abstract: PURPOSE:To obtain an element driving method which does not degrade the optical switch capacity and the element, by allowing the uneven distribution of ions at a DC voltage impression time only for a short period or reducing the extent of uneven distribution in the optical switch element driving method using ferroelectric materials. CONSTITUTION:A light 9 made incident on an optical switch array 14 from a light source 8 is transmitted selectively by electric fields impressed to signal electrode terminals K1-K2048 and a common electrode and is irradiated as a spot to the surface of a photosensitive drum 16 by a condenser lens 15. Switches SA and SB are main switches of voltage sources from which voltages are impressed to a signal eletrode group 6a and a common electrode 6b, and terminals P1-P2048 control individual switch parts. A signal input terminal Q1 short-circuits paired electrodes. A signal terminal Q2 impresses reverse voltage to counter electrodes to discharge the accumulted electric charge with respect to polarity. Thus, the electric charge accumulated near an oriented film by application of DC voltage is reduced or eliminated to reduce uneven distribution of ions as much as possible or prevent this uneven distribution, thus preventing the degradation of the capacity of the optical switch element.
