摘要: 本研究之主要目標在於研發一個新式三波長白光LED 之製作,結合此種光源完成20” LCD 側向入光之LED 背光模組。應用高功率之大面積LEDs 結合高散熱之SMD 封裝技術,搭配固態磷化鋁銦鎵紅光磊晶膜,完成一具有較佳色彩表現之新式螢光粉白光LED 元件與非螢光粉之全固態白光LED 元件。本研究之白光發光二極體元件結構是由氮化鎵系之藍、綠光LED 及磷化鋁銦鎵紅光磊晶膜所組成。應用晶圓接合技術將紅光磊晶膜從砷化鎵基板上移除貼於透明之玻璃基板上,配合螢光粉白光LED 與兩藍兩綠之LED,以光激發光之方式產生紅光,藉以擁有紅、綠、藍三種色光混成白光,其色座標分別為x = 0.383, y = 0.343 與x = 0.311, y = 0.293。以此兩種光源組實際完成20” LCD背光模組,其各別亮度可達8790、5250 nits,搭配液晶面板後亮度分別為210、135 nits,色彩表現範圍分別為NTSC 65.8% 與NTSC 96.4%。
The main purpose of this study is to develop an novel three-wavelength white LED light source for 20” LCD edge-lighting backlight module. We developed a SMD package technique of large area LED which had high power and high thermal dissipation. After combining with solid-state AlGaInP epi-layer, the novel YAG-based phosphor white light LEDs and all-solid-state white light LEDs which has better color representation. The device structure of the white LEDs is composed of a GaN-based blue LEDs, green LEDs and AlGaInP epi-layer. Then the GaN-based LEDs can generate trichromatic colors and achieve a white light source. The chromaticity coordinate of phosphor white LEDs and all-solid-state white LEDs are x = 0.383, y = 0.343 and x = 0.311, y = 0.293. Actually, we finished two types of 20" LCD backlihgt modules, its luminance can reach 8790 and 5250 nits, after combining with the liquid crystal panel, the luminance is 210 and 135 nits, the color gamut is 65.8% and 96.4% of NTSC.
