摘要： In this work, high-color-purity transmissive colors with high angular tolerance are proposed. The metal/dielectric film stacks, by means of induced transmission effect, are able to achieve ～60% peak transmission and ～60 nm transmission band, so as to cover a large color gamut. The filter presents good incident angle insensitivity up to 60 degrees, ascribed to the combined contribution of the constant total phase shift within the intermediate dielectric layer and the relatively high refractive index of the dielectric layers. And the matching of the optical admittances for metal/dielectric layers is responsible to the high transmission of the metal-based film stack. Moreover, the optical constants of silver film, affected by deposition technology have a great impact on the optical property of the color device including the bandwidth and peak transmission. And the thickness of the top dielectric layer as well as the metal/dielectric stack number can also alter the performance of the color filter.
