ABSTRACT:
A driving device for a light shutter array having a plurality of serially aligned shutter elements each having an electro-optical effect to polarize an incident light by applying an electric field thereto. The device includes a plurality of individual electrodes each provided on a wall of a shutter element and a common electrode provided on an opposed wall of the shutter element. A driving pulse voltage is applied to the individual electrodes to activate the same according to recording data for turning ON/OFF the respective shutter elements in a first recording period and according to inverted recording data in a subsequent second recording period. The common electrode is grounded in the first recording period. A pulse voltage same as the driving pulse voltage is applied to the common electrode in the second recording period.
