Symmetric H state lifetime in splayed nematic liquid crystal devices
Abstract
The dynamic behavior of splayed nematic devices during sudden voltage application is investigated in detail, both experimentally and through simulation. The symmetric H state forms transiently under such drive conditions, and we show that the lifetime of this state is strongly dependent on the liquid crystal material parameters and the applied voltage. The decay of this state to the asymmetric H states is shown to occur via domain growth: isolated regions of the device form the asymmetric H states, and these domains then grow, taking over the areas containing the symmetric H state.
