摘要

本文报道了一种具有全填充因子的微透镜阵列(MLA)薄膜，并介绍了其在有机发光二极管(OLED)上的应用，以提高其解耦效率。提出了一种高凹陷比的无间隙MLA薄膜，并采用简单的微加工工艺，包括形成沟槽和聚合物的保形气相沉积。将MLA薄膜应用于OLED面板，其解耦效率最高可提高48%。具有全填充因子的高凹陷MLA光学薄膜有望为包括OLED在内的平板光源的各种显示或照明应用提供卓越的光学效率。

Microlens Array Film with Full Fill Factor for Enhancing Outcoupling Efficiency from OLED Lighting

This paper reports a microlens array (MLA) film with full fill factor and presents its application to organic light emitting diode (OLED) for improving outcoupling efficiency. Gapless MLA film having high sag ratio is proposed and fabricated by simple micromachining process including trench formation and conformal vapor phase deposition of polymer. As applying MLA film to OLED panel, the outcoupling efficiency increased by maximum 48%. High-sag MLA optical film with full fill factor is expected to give remarkable optical efficiency to various display or lighting applications of the flat panel light sources including OLED.
