Optical Color Compensation Film for Plasma Display Panels

Abstract

An optical filter providing color compensation for plasma display panel modules was prepared using a cyanine dye that was designed to attenuate visible light from neon plasma discharge. Two types of the optical filters were devised and their effect on the image quality was evaluated. A film optical filter eliminated the double image or reflection observed using glass filters and provided a greater bright room contrast ratio. Our results indicated the overall color purity was improved by 12.7% with a red color purity correction and that the color temperature was increased by 2500 K using the film.
