Science

Belyaev V.V. conducts research on the development of new liquid crystal (LCD) displays with improved visual and operational characteristics. The development will allow to create devices with picture orientation molecular microstructure, 2-and 3-dimensional permanent polarization-optical, nano-, micro- and macro-electron-optical devices. Studies are aimed at obtaining materials and methods that will preserve the advantages of liquid crystals, while operating to preserve the recorded information, despite the mechanical deformation of the device.
Belyaev V.V has published 440 scientific papers, including 6 monographs, 169 articles in journals, 42 copyright certificates and patent inventions, utility models, industrial designs, which are used in enterprises of Russia, Belarus, the Republic of Korea, the United States.

V. Belyaev, A. Solomatin, and D. Chausov, “Phase retardation vs. pretilt angle in liquid crystal cells with homogeneous and inhomogeneous LC director configuration”, Optics Express 21, 4244-4249 (2013).

Phase retardation of both extraordinary and ordinary polarized rays passing through a liquid crystal (LC) cell with homogeneous and inhomogeneous LC director distribution is calculated as a function of the LC pretilt angle 0θ on the cell substrates in the range 00θ90≤≤°. The LC pretilt on both substrates can have the same or opposite direction, thereby forming homogeneous, splay, or bend director configurations. At the same pretilt angle value, the largest phase retardation ΔΦ is observed in splay LC cells, whereas the smallest phase retardation is observed in bend cells. For the 0θ values close to 0, 45°, and 90°, analytical approximations are derived, showing that phase retardation depends on LC birefringence variation. ©2013 Optical Society of America OCIS codes: (160.3710) Liquid crystals; (120.0120) Instrumentation, measurement, and metrology.

Belyaev V. V., Solomatin A. S. Optical features of hybrid liquid crystal cells at different angles of light / / Optical Journal 2015, vol. 82, №1. Pp. 41-48. (2015).

A theoretical and computer model of the dependence of the phase delay difference on the pre-slope angle of the liquid crystal director in cells with inhomogeneous distribution of the director over the cell thickness and at different angles on the opposite cell substrates was developed. The method of calculation of dependence of the normalized difference of phase delays depending on the law of distribution of a tilt angle of the director on a cell thickness was described. The method is applicable for different types of cells of liquid crystals with positive or negative dielectric or optical anisotropy. The proposed method of measuring the tilt angle on one of the substrates of the hybrid cell at a known angle prednislone liquid crystal on the other substrate. The developed model can be used to calculate optical compensators. Codes OCIS: 260.1440, 130.5440.

Belyaev V. V., Perspective applications and technologies of liquid crystal display devices and Photonics // Liquid crystals and their practical use. 2015 Volume 15. Number 3. Pp. 7-27.

To-date applications of different types of liquid crystal devices are reviewed. Main applications presented relate to displays and some problems of light control (photonics). The display is considered as a complex system. Besides the liquid crystals (LC) and electrooptic modes almost all LC device components that effect on the LCD operation and visual performances are reviewed. Brief data on the LC devices market and its segments are presented. Special attention is paid to the components, technologies and applications poorly described in the Russian literature.

Liquid crystal (LC) director distribution and optical transmission for different types of heterophase systems with different LC boundary conditions is simulated. The first type is a transparent isotropic material with spherical or cylindrical objects. The second type is an LC layer incorporating an isotropic transparent or non-transparent object. The systems parameters’ influence on LC display (LCD) performances is discussed.
