摘要

本研究結合光微影、熱整形、模造與紫外線成形技術，將正六方形底部的微透鏡陣列翻製於撓性聚脂(PET)基板上，並且將這些微透鏡陣列輪流貼附在藍光有機發光元件(OLED)上，藉以促進有機發光元件的電流效率與功率效率。本論文主要探討正六方形底部微透鏡陣列結構的填充率和熱處理溫度對於光阻結構熱整形效果之影響，同時也討論微透鏡陣列結構參數對於藍光有機發光元件的電流效率、功率效率、色座標之影響。

In this study, we combined the photolithography, thermal reflow, molding, and UV-forming techniques to fabricate hexagon-based microlens arrays on flexible polyester (PET) substrates. Besides, we attached microlens arrays in turn on the same blue organic light-emitting device (OLED) to improve its luminous current efficiency and luminous power efficiency. The first attempt of this study was to investigate the influences of the fill factor of hexagon-based photoresist plates and the temperature on their morphology after thermal reflow. The second purpose was to study the influences of the structural parameters of microlens arrays on the efficiency improvement and CIE coordinate of the blue OLED.
