Color modulation properties of a liquid-crystal device
Abstract:
The color modulation properties of a twisted-nematic liquid-crystal device are studied based on the Jones calculus. The usefulness of Jones calculus is demonstrated for the blue mode of a supertwisted birefringent liquid-crystal device, after which some experimental results of the color modulation effect for a twisted-nematic liquid-crystal television are presented. We investigated the color dependence of the transmitted light on the applied voltage by using a chromaticity diagram. Most of the experimental results are well explained by the theory derived from the Jones calculus.
