    • 　　本論文研究為高效率、高準直、高輝度且薄邊框的側入光式LED導光板模組設計。可應用於筆記型電腦（NoteBook）、平板電腦、i-pad、智慧型手機等小尺寸的3C產品，不但具有防窺功能，且在戶外不會因為外界光線過亮讓眼睛瞳孔縮小而顯得螢幕過暗的情形發生。
    　　本架構可將邊框的寬度縮減至2.5mm以下，可達到近乎無框的美觀效果，且導光板厚度壓在2.0mm，在高準直度的部分，將可視角縮減至半角7度以內，大幅提高能量使用效率。

    In this thesis, a novel edge-lit backlight module was proposed, which had high efficiency, collimation, luminance and a thin border. The module can be applied not only to small-sized or mobile product, but also to notebook or tablet PC. Furthermore, it can also provide special function such as anti-peep, sunlight readability. In architecture, this backlight module has very narrow border of 2.5 mm or below; a folded and piece-up light guide plate of 2.0 mm thickness. The FWHM of the output intensity of this module is less than 14
    degrees, and the on-axis luminance is up to 20000 nits.
