Abstract

The sticulation of electrohydrodynasic (EHD) instability and the focal conic (FC) to hoaeotropic (H) transition (F-H) v.v. in S, phase liquid crystals (LC) have been investigated. This processes are the reason of FC and H stable structure foriation with saxsisua and iiniiua light scattering respectively. Data indicate that the .edia peculiarities and aechaniss of the electrooptical effects enable to stisulate the structure transition by the ani sotropy of IC cell surface relief. The relief anisotropy is the equidistant rectangular network of modulated layer disturbances similar to a asquare one is more energy advantageous. It determines the decreasing of the threshold voltage and IC response time. The obtained results will enable us to solve the boundary task by the constructivetechnological methods of the LC display development having the regular matrix pixels and using the principle of the control field light scattering. It possible to fabricate IC display without the alignment layers having the cont-' rast over 40:1, the optical reaction time less than 50 is and threshold less than 50 V. 0-8194-21 12-X/96/$6.00 SPIE Vol. 2731 /63 Downloaded From: http://proceedings.spiedigitallibrary.org/ on 06/23/2016 Terms of Use: http://spiedigitallibrary.org/ss/TermsOfUse.aspx
