  • Liquid crystal display including O-type and E-type polarizer
    Patent number: 7453640
    Abstract: Devices of information displays, in particular liquid crystal displays, which can be utilized in indication devices for various purposes. Liquid crystal displays, according to this disclosure, contain at least one layer of liquid crystal placed between two plates, on each plate there has been formed or applied at least one electrode or a system of electrodes, or an active matrix, and at least one layer of polarizer; while at least one polarizing layer is an E-type polarizer and at least one polarizing layer is an O-type polarizer.
    Type: Grant
    Filed: January 7, 2006
    Date of Patent: November 18, 2008
    Assignee: Nitto Denko Corporation
    Inventors: Pochi Yeh, Alla Y Sakharova, Yuri A Bobrov

  • Dichroic polarizer and material
    Patent number: 7031053
    Abstract: The invention pertains to thermo-resistant and light-resistant dichroic polarizers based on thin films of dichroic matters, in particular organic dyestuffs, in which molecules are ordered in a crystalline structure and applied on the surface of the substrate. The dichroic polarizer is characterized by the fact that it contains at least one anisotropically absorbing film comprised of oriented molecules.
