Abstract:	在本論文中，主要目的是利用多晶片封裝LED作為LCTV背光機構之光源，並且設計了一薄型化的混光腔體。過程中，利用BSDF分佈及蒙地卡羅光追跡法成功地建立混光腔體中所使用的擴散板之散射模型。最後，我們製作了一台採用熱插拔式多晶片LED為背光源之42吋LCTV，並對其作一系列實驗分析及問題討論。In the thesis, we use multi-color LEDs to replace CCFLs of an LCTV and design a thin backlight unit. In the design process, we incorporate the BSDF model with Monte Carol ray tracing to establish the scattering model of the diffuser in the backlight module, and successfully simulate the transmitted and reflected lights by the diffuser. Finally, we fabricate the backlight unit for a 42-inch LCTV by using multi-color LEDs with hot-plug package. The optical performance of the LCTV with the LED backlight unit is analyzed.
