Description

1310250 九、發明說明: 【發明所屬之技術領域】 —本發明涉及一種發光二極體及其製備方法,尤其涉及 一種侧光式發光二極體及其製備方法。 【先前技術】 ' 習知背光模組中之發光裝置一般爲冷陰極熒光燈 (Cold Cathode Fluorescent Lamp, CCFL)與發光二極體 • (Light Emitting Diode,LED)。其中,發光二極體係一種固 態之半導體發光裝置,其係利用二極體内分離之兩種載流 子(帶負電之電子與帶正電之電洞)相互結合而產生光。與 冷陰極熒光燈相比,發光二極體具有高色彩飽和度、不含 汞、壽命長及可透過驅動電流調整色溫等優點。 請參閱圖1,採用習知發光二極體之背光模組示意 圖。該背光模組10包括反射罩11,於反射罩11之上方依 次包括有光源,含有反射片131之透明塑膠板13及用於擴 •散光線之光學片14。其中,該光源包括多個發光二極體 • 12,每個發光二極體12包括含有發光區1211之半導體發 -光元件121和設置於半導體發光元件121上之導光棱鏡 122。導光棱鏡122包括使一與半導體發光元件121配合而 封閉發光區1211之橫截面爲“门”形之入光面1221、一 與該入光面1221相對之漏斗形反射面1222及位於導光棱 鏡122侧面並與反射面1222相連之出光面1223。其中, 半導體發光元件121發射之光線從入光面1221進入導光稜 鏡122,反射面1222將部分入射光反射至出光面1223而 6
