Paper Abstract

The stimulation of electrohydrodynamic instability and the focal conic (FC) to homeotropic (H) transition (F-H) v.v. in SA phase liquid crystals (LC) have been investigated. This processes are the reason of FC and H stable structure formation with maximum and minimum light scattering respectively. Data indicate that the media peculiarities and mechanism of the electrooptical effects enable to stimulate the structure transition by the anisotropy of LC cell surface relief. The relief anisotropy is the equidistant rectangular network of modulated layer disturbances similar to a square one is more energy advantageous. It determines the decreasing of the threshold voltage and LC response time. The obtained results will enable us to solve the boundary task by the constructive-technological methods of the LC display development having the regular matrix pixels and using the principle of the control field light scattering. It is possible to fabricate LC display without the alignment layers having the contrast over 40:1, the optical reaction time less than 50 ms and threshold less than 50 V.
