應用於平面顯示器之微/奈米光學膜片技術與發展趨勢

微/奈米光學膜片與導光結構的設計在平面顯示器的發展過程中扮演著關鍵角色，而兩者所牽涉到的製程平台為可大量生產的超精密加工與 R2R 成形技術。為因應不同尺寸下的多功能平面顯示器之發展，廠商應更積極朝向開發效果佳、成本低的製程及附加價值高的創意設計發展，以提供本身的競爭優勢。在國內科專計畫的推動與國內業者的通力合作之下，屬於國內自有的關鍵光學零組件及其衍生之光機設計與製作技術已漸成熟。本文就利用平面或滾筒超精密加工技術所發展的代表性技術與產品進行介紹，包括:超薄導光板、防刮增亮複合式光學膜片、按鍵導光膜、奈米結構抗反射膜片等等。

The micro/nano structured films play important roles in the development of display, of which the mass production technology is based on ultra-precision machining and roll-to-roll forming. To apply the related technologies in different sizes, the factories need to develop more flexible, low cost, and better performance technology platform. In Taiwan, the collaboration with government and private companies has helped ITRI develop several key components in process and design. This paper is a short review of the roll-to-roll or ultra-precision technology based products, including ultra-thin light guide、optical film of anti-abrasion and brightness enhancement、key pad light guide film and Anti-reflection with Moth-eyed structures.
