Effect of black dichroic dye on temperature dependence and order parameter of LC mixture for TN LCD

Present paper contains results of studies on TN LC mixture containing black dichroic dye. The general information concerning a principle of action of TN display with dye is presented. The effect of dye on temperature dependence of LC order parameter, optical anisotropy and dielectric properties is discussed. Transmissive characteristics of a display for different dye concentration are given. Contrast coefficients and transmission in on-state at room temperature are presented.© (1998) COPYRIGHT SPIE--The International Society for Optical Engineering.
