摘要： The invention belongs to the class of thermostable and lightfast dichroic polarizers made using thin films of dichroic organic substances, in particular, the organic dyes in which molecules of a dichroic organic substance are ordered in a crystalline lattice and which are deposited onto either a rigid or a flexible substrate surface.
The technical result consists in the fact of widening the spectral range of the polarizer operation and in simultaneous improvement of the polarizer's polarizing characteristics.
The proposed dichroic polarizer is manufactured using the film which at least partially has the crystal structure and which contains at least one dichroic organic substance with the planar-structure molecules (or molecule fragments). The dichroic substance is selected such as to have at least one maximum in each of the following regions of the absorption spectrum curve: 400-700 nm and/or 200-400 nm, and 0.7-13 microns. The film order parameter S corresponding to at least one maximum in the 0.7-13 micron region of the absorption spectrum curve is no less than 0.88. This parameter is calculated from the expression S=(D ⊥ -D 11 )/(D ⊥ +2D 11 ), where D ⊥ and D 11 are the optical densities measured in the polarized light when, correspondingly, the polarizer's polarization axis is perpendicular and parallel, respectively, to the polarization plane of the spectrometer electromagnetic radiation.

摘要： A liquid crystal display has a first substrate plate (1) and a second substrate plate (2), and a liquid crystal layer disposed between the plates (1) and (2). A polarizing coating (8) or (9), 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 (1) and (2). Orientation of the polarizing coating (8) or (9) 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.

摘要： The present invention pertains to the field of polarisation devices and may be used in lighting fixtures, in the production of glass for the building industry as well as in displays. This invention relates to a dichroic polariser that comprises a substrate and at least one layer for the dichroic absorption of electro-magnetic radiation. The polariser also comprises two reflective coatings, one of which at least is partially transparent, wherein the layer for the dichroic absorption of electro-magnetic radiation is placed between said reflective coatings. The widths and the materials of said absorbing layer and reflective coatings are selected according to conditions that provide, at the output of said dichroic polariser, an interference minimum of the absorption component for at least one wavelength. According to this invention, the efficiency of the dichroic polariser is increased due to the higher polarisation level of the electro-magnetic radiation as it exits said polariser, while maintaining a high transparency (reflection) ratio for the non-absorbed component.
