Abstract
The conditions for the emergence of a fast electro-optical mode in a liquid crystal cell with a short period (p = 1.8 μm) of interdigitated electrodes have been investigated. The electro-optical switching in two liquid crystal mixtures differing in viscosity and dielectric and optical anisotropies has been studied through numerical simulations and experimentally. The fast mode switching times are shown to be in the submillisecond range and to be related to the switching of a near-electrode liquid crystal layer comparable in thickness to the period of the electrode structures. The inclusion of the entire liquid crystal volume in the switching process is characterized by a slow mode with considerably longer times.
