摘要

液晶顯示器背光模組之光學膜片，具備提高亮度、增加均勻性與降低moiré等光學特性，近年來這一類光學膜片有重大的變革，其中變化最多的應屬將擴散膜、稜鏡片、偏極增亮膜、導光板等多項功能合併設計，成為複合化、一體化以及特殊化之新型式光學膜片。此整合型光學膜改進了以往單一膜片單一功能之多膜片模組架構，藉此降低膜片的使用數量，並降低總體成本。本文從相關專利技術分析為基礎進行歸納，並配合全球市場上之產品技術予以分析解剖，並解析國際上之最新設計技術與發展趨勢。

並列摘要

The optical film of the backlight module of the liquid crystal display provides the optical characteristics on improving luminance, increasing homogeneity, and reducing moiré. In recent years, there are significant changes on optical films, specifically on diffuser film, prism film, polarized bright enhance film, and light guide plate. It has become a new model optical film with compound utilities. This integrated model has replaced the old single film models in reducing the amount of films to be used, thus substantially reduces the cost. This article probes into the edgy technologies and trend through an analysis on relevant patents and techniques and the manufacturing techniques from a worldwide angle.
