Color Polarizers For Liquid Crystal Displays

Abstract

This paper describes a new line of color polarizing elements employing high stability dichroic dyes as the chromophore. In addition to providing multicolor digital and graphic display information the importance of dichroic dye chromophores lie in their ability to withstand elevated temperatures and humidity. The main emphasis of this paper therefore, focuses on endurance performance comparisons between dichroic dyes and conventional iodine chromophores. Spectral transmission curves are also presented illustrating a custom color capability achieved through the additive and subtractive mixing principles.
