High-color-purity transmissive colors with high angular tolerance based on metal/dielectric stacks
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.

摘要： We proposed microfluidic quantum dots light-emitting diodes using a liquid organic semiconductor (LOS) and quantum dots (QDs) solutions. LOS and QDs solutions were used as a backlight and a luminophore, respectively. Channels for the QDs solutions were stacked on the LOS backlight. With applying voltage, red photoluminescence (PL) emissions of the QDs solution excited by the LOS backlight, was observed. The full width at half maximum of the red-PL emission was 29.8 nm, which is narrower than that of the LOS backlight by 40%. The proposed device is expected to provide highly-bright flexible displays with high-color-purity.
