摘要: 
中小尺寸LCD顯示器在各類資訊(PDA)、通信(手機)或電子產品(數位像機)中,已成為不可或缺之關鍵元件,其中之背光模組之性能優劣,更是在顯示器之整體表現中扮演非常重要的角色。目前背光模組發展趨勢傾向於利用新型微結構(即本文之光學拋光面微結構)做為導光板底部之網點(Pattern),但由於不同於傳統蝕刻或網板印刷表面之散射機制,除了在光型上看出明顯的差異外,在均勻性方面更是值得我們做進一步的努力。
本研究之主體為光學拋光面(Optical Polished)微結構對於高輝度背光模組特性之影響,其中包含光型分佈(Cartesian Intensity)、輝度(Luminance)與均齊度(Uniformity)之表現。並藉由光學模擬軟體之輔助,首先找出新型微結構與傳統微結構網點的差異所在,除了以理論的計算加以設計改進外,也得到了軟體模擬上的驗證,最終應用於實體產品開發上亦確實獲得明顯的改善成果。

The role of middle to small size LCD display is very important in many products, for examples, PDA, Mobile Phone and Digital Camera etc. One of its core components is the back light module and its performance is directly related with the quality of the whole display. At present, some new methods are used to fabricate the polished surface of the scattering dots on the light guide plate which shows batter luminance performance than the rough surface formed by traditional ink printing or etching process. However the uniformity of this new type of microstructure needs to be improved due to its different scattering mechanism.
In this research, we study the effects of the optical polished surface on the characteristics of the back light module, including the beam distribution, luminance and uniformity. With the help of optical design software, the differences between traditional rough surface and new polished surface are examined. Also the theoretical analysis is employed to improve the structure of scattering dots, and the results are verified with the simulation tools. Finally the simulation results are successfully applied to real back light modules manufacture and the performance enhancement are evident.
