  • Patent number: 4658271
    Abstract: An electrooptical recording device for recording image information in an optical printer having a light source, an electrooptical switch and a recording medium and further including an electrode array having a plurality of central electrodes and associated external electrodes for controlling a plurality of N recording spots by half the number of driver stages. The recording spots are light sensitive and lie along a recording line and are exposed to the light source when a voltage is applied to a select pair of the electrodes deposited on the optically active material causing the electrooptical switch to change from an opaque to a transparent state. By controlling the operation of each pair of electrodes, the pattern of recording spots that are exposed is controlled.
