摘要

顯示器(Display)婦是資訊科技時代人們傳遞訊息與相互溝通的重要界面，而顯示器的發展逐漸由大體積的的陰極射線管(CRT)，轉型為較為輕薄的液晶平面顯示器(LCD)，其中TFT-LCD具有輕、薄、體積小及低耗電量的優點，所以廣泛的應用於日常生活的電子商品上，因此TFT-LCD面板的需求日益增加；而隨著台灣面板產業的產品生命週期逐漸趨於成熟，加上面對韓國與日本的激烈競爭下，持續降低成本是當前各面板廠商全力追求的課題，因此若是能提升TFT-LCD面板產品品質及良率，枕能減少不良品與成本的浪費。所以本文將針對TFT-LCD面板探討其製造流程整理出5個重要的品質特性製程，並利用六標準差和製程能力弱度指標(C(下標 pp))之評估模式以及運用工業統計的方法，找出影響TFT-LCD面板品質不佳之重要品質特性製程，同時分析造成品質不佳的原因，再以工業實驗設計探討最佳的製程水準並以管制圖監控製程品質，希望藉由六標準差之MAIC流程持續改善TFT-LCD面板的製程品質，以協助業者提升TFT-LCD面板產品品質，進而達到6標準差品質水準的目標。

The display is an important interface of sending message and communicating each other for people in the information technology age The display has gradually developed from cathode ray tubes (CRTs) to liquid crystal displays (LCDs) Among them, thin film transistor - liquid crystal display (TFT-LCD) possesses some real advantages It is thinner, smaller and lighter, and draws much less power than other display technologies. Hence, TFT-LCD panels are widely applied in daily electronic products, and the capability requirement of TFT-LCD panels is gradually increasing Under product life cycle of TFT-LCD panels industry is gradually getting into mature period, meanwhile, Taiwan's firms severely competes with Korea and Japan. continuous cost-down is an all-out pursuing topic for Taiwan's panel firms currently Suppose the quality and yield of TFT-LCD panels can be effectively enhanced, the unqualified rate and cost of TFT-LCD panels will be reduced In this study, the manufacturing processes of TFT-LCD panels are discussed, and then five important quality characteristics of TFT-LCD process are summarized and selected Moreover, applying the evaluating model of Six Sigma and process incapability index C(subscript pp), and performing industrial statistic methods to find the key quality characteristics that making the quality of TFT-LCD panels bad Meanwhile, the important factors that causing the process quality characteristics of TFT-LCD panels poor are analyzed and investigated Next, the design of industrial experiment is used to find the corresponding best process quality characteristic level out, and then control charts are employed to monitor/control the process quality for TFT-LCD panels The process quality of TFT-LCD panels can be continuously improved by the MAIC process of Six Sigma, and it can be utilize to assist the firms of TFT-LCD panels in the enhancement of process performance and quality Finally, the target of 6-Sigma quality level can be reached.
