Abstract
ABSTRACTThe optimized electro-optical (EO) properties of inverse twisted nematic (ITN) liquid crystals (LCs) were demonstrated by utilizing liquid doping technique. ITN LC display is a driving system having 90° twisted structure on homeotropic polyimide with negative LCs. Toluene was chosen as dopants and doped into ITN LCs which successfully improved the driving voltage and response time of ITN LCs. The main reason of these EO properties enhancement is that toluene molecules penetrated between LC molecules and decreased the visco-elastic coefficient of LCs. The simplicity of liquid doping technique shows the potential to developments of a wide range of applications.
