Smectic layer influence induced by surface anchoring on its dynamic optical response behavior

Influence of surface pre-tilt setting on dynamic initial driving torque of an SSD (Smectic Single Domain) liquid crystal drive mode has been investigated. Unlike typical nematic liquid crystal drive mode, a smectic liquid crystal drive mode has some significant influence by its smectic layer switching behavior. To clarify the layer switching influence, an initial driving torque was investigated how the initial torque was formed, how the torque interacted to the dynamic layer distortion behavior, and so on. Empirical approaches included both dielectric relaxation behavior and dynamic retardation switching behavior. These measurements suggested that the initial surface pre-tilt setting was one of the primary influential factors to govern dynamic optical response profile of an SSD-LC panel.
