  • Patent number: 4984198
    Abstract: The disclosed liquid crystal electrooptic memory device uses a ferroelectric liquid crystal sandwiched by a pair of molecular oriented films attached to opposite surfaces thereof, and a pair of transparent conductive films are attached to the outside surfaces of the molecular oriented films, respectively. An impedance having a constant electrostatic capacitance and a variable resistance is connected to one of the transparent conductive films. Further, an electric pulse source is connected across the transparent conductive films through the impedance. When a pulse from the pulse source is applied to the transparent conductive films, light transmittance of the ferroelectric liquid crystal is set at different levels depending on the resistance of the impedance. Thus, the resistance of the impedance is memorized in the form of the light transmittance of the ferroelectric liquid crystal. The impedance can be in the form of a photoconductive film attached to the molecular oriented film.
