Abstract
Focal-conic texture formation of smectic A-phase liquid crystal by virtue of the electrohydrodynamic instability is studied. The relaxation of the dynamic-light-scattering structure to focal-conic domains, the stability and the optical density of these domains depend on the amplitude, the frequency and the technique of the removal of the electric field. The light scattering difference between the dynamic state of liquid crystal and focal-conic one is small at the field providing the turbulent electrohydrodynamic perturbance. The analysis of the data permits us to define the turbulence condition in regard to the electric field as U equals Uth, where Uth is the threshold voltage. Obtained results may be used to design liquid crystal display with the controlled electric field scattering.
