摘要：分散型電致發光（EL）是將無機熒光體粒子分散于有機聚合物中的熒光體層，并將功能性的膠體層疊積成基本單元，通過印刷加工實現器件化的新光源。但色純度和亮度低，新開發的混合式EL器件融合了色純度優的有機色素，是具有高亮度、高顯色性和高附加值的新型面光源發光器件。 敘詞：電致發光（EL） 分散型 有機色素 亮度 顯色性 新光源 Abstract： The dispersion-type EL is the new light source resulting from the following process: the inorganic phosphor particles dispersed in the phosphor layer of organic polymers, and then pile functional colloid cascading into basic unit; finally, become components by printing process. With this process, the lighting has low color purity and brightness. The newly-designed mixed EL component is a new lighting component with high brightness, high color rendering and high value-added, which combines organic pigment with excellent color purity Keyword：Dispersed type, Organic pigment, Brightness, Color rendering, New light source
