根據工研院IEK預估，全球軟性電子產品將從2008年開始陸續成熟，而整體市場將從2010年開始成長，產值約20億美元，其中軟性顯示器(Flexible Display)將是最主要的應用產品。在軟性顯示器快速發展的趨勢下，為滿足市場大量需求，軟性顯示器勢必得走向量產階段。然而對於軟性顯示器即將邁入的量產，如何從試產的實驗過程找出中影響良率的品質要素，並將實驗製程中所面臨的問題做有系統的分析與探討，幫助軟性顯示器日後發展量產製程影響良率之困擾現象問題分析，將為未來製造及推動軟性顯示器技術普及的關鍵。本研究透過專家訪談，應用特性要因圖結合限制理論之現況樹，分析軟性顯示器Roll to Roll Laser Etching製程中可能影響良率的問題與現象，建立影響良率之關鍵要素與關鍵問題。再藉由層級分析法之分析程序，尋找Roll to Roll Laser Etching製程中影響良率之核心問題。最後以核心問題運用限制理論之衝突圖、未來樹、條件樹及轉移樹，研擬適用於軟性顯示器Roll to Roll Laser Etching製造程序核心問題的解決方案。本研究主要貢獻在於為軟性顯示器關鍵製程建立一個尋求核心問題的流程與解決製程之問題分析模式，期望有助於軟性顯示器日後量產之順利及製程穩定性，做為日後參考依據。 According to the prediction of Industrial Economics and Knowledge Center of Industrial Technology Research Institute (ITRI IEK), global flexible electronic products had been getting mature since 2008. The market of related products is estimated to grow exponentially to a total value of two billion USD in 2010. Of this market, flexible display is one of the most widely demanded products. As flexible display demand grows, they must go into mass production to sustain a consistent supply. Before flexible displays enter its mass production stage, it is crucial to go through a trial run period to find key characteristics and key problems that can significantly alter the mass production yield rate. It is of equal importance that all the problems faced during the trial production are systematically analyzed and studied, to positively influence the yield rate and perfecting the technology and engineering setting that is crucial to a smooth mass production process. This research utilizes Expert Interviews, Cause & Effect Diagrams, and the Current Reality Tree within the Theory of Constraint to analyze the effects that the key characteristics and key problems of the Roll to Roll Laser Etching process used to manufacture Flexible Displays can have on yield rates. This research further uses the Analytic Hierarchy Process to find the core problems that Roll to Roll Laser Etching can cause, and uses such core problems in a Conflict Resolution Diagram, Future Reality Tree, Prerequisite Tree and Transition Tree of TOC to find applicable solutions problems of the Roll to Roll Laser Etching manufacturing process. This research is dedicated to finding a systematic flow and analytical process to create solutions in the manufacturing process of Flexible Displays, in hopes that it can stabilize the yield of production in its later stages of mass production.
