RECENT LIQUID CRYSTAL MATERIAL DEVELOPMENT FOR ACTIVE MATRIX DISPLAYS

The structural dependence of the optical and dielectric physical properties of liquid crystal (LC) materials is investigated with the aid of molecular modeling. A material characterization of LC materials is made using fundamental physical measurement values, e.g. optical, dielectric, elastic, and viscous parameters. A novel mixture design based on selected LC materials leads to significant improvements that fulfill the requirements for active matrix LC displays, for instance, fast switching times, lower power consumption, and wide operation temperature ranges. The development of LC displays from the material supplier's point of view is briefly reviewed.
