  • Class of dichroic dyes for use with liquid crystals
    Patent number: 4401369
    Abstract: A cholesteric guest-host liquid crystal composition having a positive dielectric anisotropy and consisting of a positive nematic host component, an optically active cholesteric component, and a tetra-azo dichroic dye guest component having a dichroic ratio of at least 0.72.
    Type: Grant
    Filed: October 19, 1981

    Assignee: Electronic Display Systems, Inc.
    Inventor: Derick Jones
  • 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

    Assignee: Texas Instruments Incorporated
    Inventors: Derick Jones, Sun Lu
  • Lyotropic nematic liquid crystals for use in electro-optical display devices
    Patent number: 4038200
    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 1 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.
