使用表面微結構的方式來增加有機發光擷示器的光萃取效率(或簡稱為出光效率),是為人所熟知常應用的技巧。然而將表面微結構應用在擷示器上,雖然具有效率提升之優點,卻會因為微結構造成雜散光的增加,進而使影像品質變差。本研究的主要目標即是利用微結構的設計方法,以解決增加出光效率與維持影像品質的兩難困境。
Conventionally, micro-structured films (e.g. microlens array films) are often applied to enhance light-extraction efficiency and increase luminance of organic light-emitting display. However, this approach was suffered from poor image quality due to stray rays caused by micro-structures. This trade-off between efficiency and image quality can be solved by our novel microlens array arrangement.
