  • Patent number: 7381348
    Abstract: The invention relates to optical devices for producing and/or transforming polarized electromagnetic emission by means of anisotropic absorption and/or optical rotation effects and/or birefringence and can be used as different polarizers (dichroic, reflecting), lagging layers (retarders), liquid-crystal displays and indicators and also for producing polarizing glass for building construction and for sun and antiglare glasses, masks, aprons and faceplates. The inventive optical device is based on at least one molecularly oriented layer of a low-molecular or oligomeric dichroic material which can form a stable lyotropic liquid crystal structure. The projection of at least one anisotropically absorbing fragment of a molecule of the dichroic material on the surface of the molecularly oriented layer of a dipole moment of optical transition is disposed in a parallel position to the optical axis of the molecularly oriented layer at least within several ranges of wavelength of the electromagnetic emission.

    Inventors: Ir Gvon Khan, Sergej Vasilievich Belyaev, Georgy Nikolaevich Vorozhtsov, Maria Leonardovna Kukushkina, Nikolai Vladimirovich Malimonenko, Nataliya Nikolaevna Masanova, Elena Yurievna Shishkina, Olga Akhmatovna Tambieva
  • Patent number: 7232594
    Abstract: The invention relates to light polarizers and devices for displaying information based on said polarizers, in particular to a liquid crystal indicating (LCI) element, and can be used on flat liquid-crystal displays, including those of the projection type, luminairs, optical modulators, matrix systems of light modulation, etc. The objective of the invention is to provide a highly efficient polarizer providing an improved brightness and color saturation of an LCI element based on such polarizer. This objective is to be attained by using, in manufacture of a polarizer and an LCI element based on such polarizer, at least one birefringent anisotropically absorbing layer having at least one refraction index that grows as the polarized light wavelength increases., i.e., having the abnormal dispersion. The use of said layer allows creation of polarizers of both the dichroic and interference types.

  • Patent number: 6846522
    Abstract: A decorative material is disclosed which comprises two polarizers and at least one phase-shifting plate placed between the polarizers. Each polarizer has a controlled direction of polarization axis. The phase-shifting plate represents a continuous layer of an optically anisotropic material containing regions differing by optical properties.

This objective is to be attained by using, in manufacture of a polarizer and a LCI element based on such polarizer, at least one birefringent anisotropically absorbing layer having at least one refraction index that grows as the polarized light wavelength increases, i.e. having the abnormal dispersion. The use of said layer allows to create polarizers of both the dichroic and interference types. Further, the use of said layer allows to create a polarizer that provides, in a relatively simple design, conversion of practically all energy of a non-polarized radiation into the polarized radiation.

  • Patent number: 6399166
    Abstract: A liquid crystal display has a first substrate plate and a second substrate plate, and a liquid crystal layer disposed between the plates. A polarizing coating, having molecules of one or more organic dyes capable of forming a lyotropic liquid crystalline phase, is formed overlying a selected surface of each plate. Orientation of the polarizing coating is obtained by applying a force to the dye molecules when in the liquid crystal phase and subsequently converting the liquid crystal phase to a solid film.
