Light-emitting device having light-emissive particles partially coated with light-reflective or/and getter material

摘要

A light-emitting device (52) suitable for a flat-panel cathode-ray tube display contains a light-emissive region (66) formed over a plate (64). The light-emissive region contains a plurality of light-emissive particles (72). Part of the outer surface of each light-emissive particle is conformally covered with a coating (74) that provides light reflection or/and gettering.
