液晶顯示器日益普遍，許多公司廠商投注許多心力於改善品質與降低成本。在本論文中，我們提出了新的17吋液晶顯示器側照式背光模組架構，俾能維持一定的光使用效率且降低製造成本。我們利用光學模擬軟體TracePro來模擬背光模組各個元件特性與架構。在新的背光模組架構中，我們僅使用到三隻燈管而達到跟原本架構(四隻燈管)一樣的亮度。由模擬結果得知，我們所設計新架構可有效降低背光模組的製造成本。

In the development of liquid crystal displays (LCDs), high manufacturing cost is a significant technical problem. Many solutions techniques can resolve the coat problem. Among these, cutting down the manufacturing coat of backlight modules is one of important issues currently considered by all the backlight module manufacturers. In this thesis, we proposed a new structure of edge-lighting backlight module for 17” LCD monitors to tentatively solve the cost problem. There are only three cold cathode fluorescent lamps (CCFLs) in the proposed backlight module in contrast with four CCFLs needed by the conventional counterparts. We used a ray tracing simulation tool, TracePro, which can model different structures for the backlight module. These simulated results show that the new edge-lighting backlight module which we designed can achieve the same brightness as the conventional one. Henceforth, the proposed backlight module can at least save one CCFL and cut the manufacturing cost.
