    Abstract: 本論文在研究使用LED當光源的液晶背光模組之輝度管理。首先,我們先瞭解液晶面板及背光模組的性質,接著對所使用的LED光源進行量測與分析,再配合光度學的原理來計算背光模組所需的能量,因此可以決定背光模組所需的光源數目,最後我們經由準確的LED模型來模擬背光模組之均勻性。 藉由液晶背光模組之輝度管理,我們製作了兩台LED背光模組:一台是使用白光LED的28吋液晶電視,另一台是使用RGB LED的42吋液晶電視,並且對於兩台電視的表現來進行探討與分析。 In the thesis, we study the luminance management of LCD backlights based on LED lighting. First, we study the characteristics of the LCD and the backlight module. Then we study LEDs in different colors. The third step is to calculate the required total flux of the backlight module based on photometry theory, and thus we calculate the numbers of the light source. Finally, we simulate the uniformity of the backlight module with precise LED model. Based on the luminance management of the LCD backlight, we fabricate two LED backlight module. One is 28’’ LCD TV with white-light LEDs, and the other is 42’’ LCD TV with RGB LEDs. The performance of both panels are presented and analyzed.
