Professor Chigrinov graduated from Faculty of Applied Mathematics, Moscow Electronics Institute, the Diploma of Engineer - Mathematician (MPhil) in 1973. In 1978, he obtained PhD degree in Solid State Physics (Liquid Crystals) in the Institute of Crystallography , USSR Academy of Sciences. In 1988, he becomes a Doctor of Physical and Mathematical Science and obtained a degree of a Professor in 1998. Since 1973, he was a Senior, Leading Researcher, and then Chief of Department in Organic Intermediates & Dyes Institute (NIOPIK). Since 1996 he was working as a Leading Scientist in the Institute of Crystallography, Russian Academy of Sciences and join HKUST in 1999.

He was a coauthor of the first LC materials and devices based on Electrically Controlled Birefringence, Twisted Nematic and Supertwisted Nematic and Ferroelectric LC materials, working at understanding the fundamental aspects of LC physics and technology, including electrooptical effects in liquid crystals and optimization of LC device configurations. Some new LC Electrooptical Modes, such as Orientational Instability in Cholesteric LC, Deformed Helix Effect in Ferroelectric LC, and Total Internal Reflection, Surface Gliding Effect and Surface Induced Orientational Transition in Nematic LC were first described by him and confirmed in experiment. The classification of the Domain Structures in LC was made based on his theoretical predictions and simulation results. Efficient Modeling Universal System of LC Electrooptics software was developed with his direct participation and supervision.

He was a coauthor of a pioneering work in LC Photoaligning Technology, which has more than 600 citations in scientific and technical journals and mentioned as one of the ten most heavily-cited and influential papers published in the Japanese Journal of Applied Physics (JJAP) since the first volume (1962).

The paper of M.Schadt, K.Schmett, V.Kozenkov, V.Chigrinov, Surface-induced parallel alignment of liquid crystals by linearly polymerized photopolymers,  Jap. J.Appl. Phys. P.I., Vol.31, pp. 2155-2164 (1992) is number 4 among the most heavily-cited and have been influential papers published in JJAP since the first volume (1962) and have been selected from the various fields of applied physics by the JJAP Editorial Board (http://www.ipap.jp/highlights/jjap.html).


Research Interests

1. Development of the new azodye and photo-crosslinking materials for liquid crystal display technology. Azo-dyes alignment was stabilized by polymerisation, which makes these alignment layers both thermo and UV stable. The fundamental description of the phenomena based on the model of the rotational diffusion in the field of linearly polarized light. Azo-dyes were shown to exhibit excellent photoalignment of polymerizable liquid crystals (PLC). The proposed dyes need an extremely low exposure dose (less than 50 mJ/cm2) for PLC alignment. New photoalignment materials are ready for the production of patterned optical films requested by modern LCD technologies. 3D LCD and transflective LCD can be made based on micro-patterned retarders obtained by LCP photoalignment. LC voltage lenses with a voltage controlled optical distance based on photoaligned LC layers are developed. The first commercialization of photoaligning materials with a complete avoiding of rubbing technology in 10th generation of LCD-TV by Sharp is announced in 2011.

2. We have obtained some good results in deformed helix derroelectric (DHF) effect.  In particular, a high quality dark state of DHF FLCD has been obtained as well as V-shape switching with a high frequency.  The application of fast V-shaped DHF-FLC for new active-matrix LCD and optical data processing devices is envisaged. One of the application id field sequential LCD-TV and projectors with high energy efficiency, high resolution and enhanced color reproduction.

3. Optically rewritable technique based on photoalignment technology is developed, as E-paper displays suffer from the high level complexity of driving electronic due to the insufficient durability of flexible conductor and contact bonding. Optical writing and erasing E-paper is a valuable contribution to the green technology, as in many cases E-paper will replace usual paper with the same quality of image. The possible but not limiting applications of the new optically rewritable (ORW) liquid crystal displays (e-paper) based on photoaligning are light printable rewritable paper, labels and plastic card displays, price labels in supermarkets, E-albums, E-advertisements.

4. New LC switches, filters, attenuators, equalizers, polarization controllers, phase emulators and other fiber optical components were produced based on photoalignment. Photonic crystals and photo-alignment technique were developed for new for LC fiber components. Application of FLC for high speed communication systems, producing elements that are extremely fast, stable, durable, of low loss, operable over a wide temperature range, and that require low operating voltages.
