We demonstrate for the first time a color filter system, based on reflective cholesteric polymers, which has no major absorptive components. We report the principles of operation, process outline, optical properties, color coordinates, extinction curves, evidence for light recycling, brightness enhancement and related issues.
The angular polarization behavior, polarization efficiency, and brightness enhancement capabilities of reflective CLC‐based broadband polarizers have been studied. New methods for compensating the angular dependence of spectral characteristics for incident angles of up to 70 degrees are reported.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
