Abstract: The invention relates to the field of optoelectronics, and may be used in devices and of visualization, displaying, storage and processing of information, in particular in projection displays, etc. Video projector consists of a liquid crystal micro display based on structure FLCoS, and an optical unit of reading the information formed in the structure FLCoS, containing a light source and projection optics, optically coupled to the structure FLCoS, and a screen, onto which the information is projected. As the electro-optical material the low-voltage ferroelectric liquid crystal (FLC) with compensated helix providing physically realizable, continuous, halftone, hysteresis-free modulation characteristic is used in the structure FLCoS. Lasers of red, green and blue radiation serve as the sources of light in three different color channels RGB.

Abstract: The invention relates to the field of optoelectronics and display technology and can be used in high speed stereoscopic glasses when working with any type of 3D display, designed to operate with active stereo glasses with standard (60-160 Hz), high (hundreds of Hz) and ultrahigh (several kilohertz) frame rate. According to the invention in optical shutters of high-speed stereo glasses a layer of the helix-free ferroelectric liquid crystal (FLC) with optimized physical parameters is used. The technical result is an increase of the optical contrast of FLC shutters, reducing the amplitude of the control voltage.

Abstract: The invention relates to the field of display technology, and can be used in systems for the free-dimensional representation of information. Active liquid-crystal 3D glasses are proposed which comprise a synchronization signal receiver, an independent power source, an electronic driver and two liquid-crystal shutters such that the liquid crystal in the latter is ferroelectric, wherein the boundary conditions for indicated liquid crystal, determined by a square coefficient of the anchoring energy of molecules in the liquid-crystal layer with the boundary surface of a dielectric or orienting coating, are related in a specific manner to the magnitude of the helix pitch and the thickness of the ferroelectric liquid crystal layer. A range is also proposed for selecting the thickness of the ferroelectric liquid-crystal layer and the condition for implementing the dielectric coating, a low-voltage power element and the electronic driver.
