譽為國內『第二半導體產業』之液晶產業，目前台灣已發展成全球第二大TFT-LCD生產國，全球4大面板廠包括三星電子(Samsung Electronics)、LG Display、友達與奇美電。2012年台灣平面顯示器總產值達新台幣1.7兆元，TFT-LCD成長率均達20%以上。在經濟部的『兩兆雙星產業發展計畫』中，影像顯示產業列為行政院國家發展重點計畫。 然而隱藏在此一榮景背後的卻存在著台灣TFT-LCD產業『關鍵零組件/設備/材料自主生產能力不足』隱憂。液晶模組內擴散片材PET光學膜幾乎全部由日、韓進口攏斷，國內液晶模組廠僅賺取微薄代工費用。光學膜佔液晶顯示器材料成本50%以上屬於重要的關鍵材料，但相關的生產技術與專利皆掌握在國外大廠手中，台灣廠商自行生產能力仍然十分薄弱，如何落實光學膜本土化進而降低成本是目前台灣面板產業須努力的目標。 國內發展PET光學膜生產廠僅南亞及新光，PET光學膜使用於面板顯示器上皆與人觀看的視覺有關，而會影響視覺上的瑕疵如膜面刮傷、翹曲、異物，是生產製程中最難管控的問題。目前面板朝超薄化及輕量化，故光學膜膜組已朝複合膜來簡化整合。因此本文的重點將採用實驗設計法，來研發複合膜及製程上品質問題點，進行分析及改善對策。The liquid crystal industry is honored as domestic “the second semiconductor industry”. Taiwan has developed into the world’s second largest TFT-LCD producer. The world’s four major panel makers including Samsung Electronics、LG Display, AUO and Chimei. 2012 Taiwan the total production value of the flat panel has 1.7 trillion, the TFT-LCD growth rate reaches over 20%. Ministry of Economic Affairs “Two Trillion, Two stars industry Development Plan”, the image display industry as the national development key plan of the Executive Yuan. However, hidden behind this boom, but there is a lack of key components / equipment / material independent production capacity of Taiwan’s TFT-LCD industry worries. Internal diffusion In the liquid crystal module sheet PET optical films almost all from Japan and South Korea imported. The domestic LCD module plants only earn a meager cost of OEM. Optical films accounted for liquid crystal display materials more than 50 percent of the cost is an important key materials, production technology and patents are lies in the hands of foreign manufacturers, Taiwanese manufacturers own production capacity is still very weak, how to implement the optical film localization and thus reduce costs is the goal of Taiwan's flat panel industry. Domestic development of PET optical film manufacturing facility only Nanya and Shinkong, PET optical film used on the panel display are related to visual and people watch will affect the visual defects such as surface scratches, the curl and foreign matter, the production process most difficult management and control problem. At present the panel toward the ultra-thin and lightweight, optical film module is to simplify and integration toward the multifuction film. Therefore, this article will focus on the design of experiment, to develop the multifunction film and improved the quality problems on production line .
