摘要

本論文分析貼附方底微透鏡陣列之有機發光元件，其外部耦合效率的增益與光學特性，本研究使用底部邊長35.4 μm以及充填比例89.6%之方底微透鏡陣列，可分別提昇有機發光二極體元件之光電效率42%以及外部耦合效率47%。此外，貼附不同充填比例微透鏡陣列之有機發光二極體元件，其光學特性，如發射光譜和CIE座標也在探討之列。

In this paper, analysis of outcoupling efficiency improvement and optical characteristics of organic light-emitting devices (OLEDs) attached with square-based microlens arrays are presented. A square-based microlens array, having a base length of 35.4 μm and a fill factor of 89.6%, increases the luminous current efficiency and outcoupling efficiency of the OLED device by 42% and 47%, respectively. Optical properties of the OLED device, such as optical emitting spectrum and CIE coordinate, have also been investigated when attached with microlens arrays having different fill factors.
