Abstract

A driving torque origin of Smectic Single Domain (SSD) liquid crystals are discussed. SSD liquid crystals provide sub-millisecond response time both at rise and decay processes, respectively with applied electric field polarity dependent switching. Some empirical approaches revealed the driving torque is highly dependent on SSD liquid crystal molecular stacking configurations. A uniformly stacked SSD liquid crystal panel showed in-plane only retardation switching and a non-uniformly stacked panel showed mixing between in-plane and out-of-plane retardation switching. A driving torque origin of an SSD liquid crystal panel is discussed based on analysis of empirical investigations.
