效率不佳’因此造成發忠元件所發出之光的波長範圍控制不 易，更導致發光效能不佳。· 此外’在傳統之無機綠光發光二極體晶粒中，受限於氮 化銦鎵（InGaN)相關材料在綠光波段的磊晶品質較差的影 響，因此無機綠光發光二極體晶粒的發光效率通常偏低。 另一方面，目前之發光二極體晶粒在紅綠_藍（RGB)背 光模組或顯示面板的應用上，由於紅、綠、藍發光二極體晶 粒之壽命各有差異’且大多需配合施加不同之驅動電壓，因 此整個發光模組的控制電路在設計上相當複雜，不利於發光 二極體晶粒在多色彩產品上的應用。 【發明内容】 因此，本發明之目的就是在提供—種發光元件，其係在 藍光或紫外光等短波長氮化物發光二極體晶粒上覆設具有 適當比例之有機光轉換材料C545P樹脂，而經藍光或紫外 1358966 光激發後可產生所需之綠光或紅光等可見光波長的光。由於 有機光轉換材料C545P具有優良之光轉換效率，因此可確 實獲得所需波長之色光，並可提升發光效能。 本發明之另一目的是在提供一種多色發光模組，可在單 一種類的短波長發光二極體晶粒上設置不同比例之有機光 轉換材料C545P樹脂，經短波長發光二極體晶粒激發這些 有機光轉換材料C545P樹脂後，可使模組同時發出多種色 光’而可應用於全彩背光模组或顯示器上。由於只使用單一 種類之短波長發光二極體晶粒，而可使用同一種驅動電壓， 再加上操作壽命接近，因此可大大地降低驅動電路設計的複 雜度。 ·* · ·- - . · · 根據本發明之上述目的，提出一種發光元件，至少包 括：一短波長氮化物發光二極體晶粒，可發出具有第一發光 波長範圍之光；以及一有機光轉換樹脂覆蓋在短波長氮化物 發光二極體晶粒上’其中有機光轉換樹脂至少包括一聚合物
