Abstract
The optimized electrooptical (EO) properties of inverse twisted nematic (ITN) liquid crystals (LCs) were demonstrated by utilizing liquid doping technique. ITN LC display is a driving system containing 90° twisted structure on homeotropic polyimide with negative dielectric anisotropic LCs. Toluene was chosen as dopant and the doped ITN LCs show improved driving voltage and response time while maintaining a very good dark state as undoped ITN LCs. Driving voltage was 1.1 V lower and the total response time was reduced by 49% after toluene doped into LCs. The main reason of these EO properties enhancement is that toluene molecules penetrate between LC molecules, and hence, the dielectric anisotropy and the visco-elastic coefficient of LCs are changed. The simplicity of liquid doping technique shows that it could be applied to a wide range of LC systems.
