  • Lyotropic nematic liquid crystals for use in electro-optical display devices
    Patent number: 4038199
    Abstract: A display device in which a thin layer of a lyotropic nematic mesomorphic composition is utilized to diffuse light from a source toward an observer by applying a suitable voltage, for example, 20 volts for a one mil layer. One form of the device transmits light through the layer. A second form of the device uses light diffused and reflected to the observer.
    Type: Grant
    Filed: June 22, 1976
    Date of Patent: July 26, 1977
    Assignee: Texas Instruments Incorporated
    Inventors: Derick Jones, Sun Lu
