抗干涉疊紋之整合型光學膜片技術與應用

在液晶顯示器背光模組之各種光學膜片，可具備提高亮度、增加均勻性、降低視覺缺陷（mura）等光學性質…等。近年來，液晶平面顯示器上之光學增亮片無須旋轉裁切製作程序即可達到消除光學干涉疊紋將是一門重要研究議題，本文提出一種抗干涉疊紋之複合式光學膜片設計技術，並運用超精密滾筒微加工技術進行多重加工法，產生具有亂數形狀與亂數分佈之多邊形二維結構之光學膜片，該膜片具備無干涉疊紋之光學特性，我們成功地消除常見之干涉疊紋並維持光學增亮功能。

The optical film of the backlight module of the liquid crystal display provided the optical characteristic of improving the luminance, increasing the homogeneity and reducing mura etc. Recently, how to eliminate Moiré without rotating film is an important issue in TFT-LCD. The design of creating polygons with random shape and distribution is carried out by using multi-time diamond-turning. An improved design for an optical film with randomization microstructures, called Moiré-free hybrid optical film, is proposed and verified in this work. We successfully eliminate Moiré and keep the ability of brightness enhancement.
