薄膜電晶體液晶(TFT-LCD)在市場上的需求度在近幾年中越來越高,對於每一家製造業者來說,品質嚴苛要求及各項的檢測準確的篩選各項品質不良,是最重要的,一般來說,都是採用人類視覺檢查,但因為人工需訓練,且需花費很長的時間,精準度也比較無法掌控。在此我們將研究如何利用更換材料與經由統計數據、不良分析、不良對策,進而達到品質提升的成效,建立相關的教育訓練,加以進行防範,不但品質良率提升,還可節省成本,因此此方法可以用來預先發現出不良成因,加以防範。;The demand for thin film Transister Liquid Crystal Display (LCD) in the market has become higher and higher in recent years. For each manufacturer, the quality requirements and various tests accurately select the quality. Bad, is the most important. In general, human visual inspection is used. However, because labor requires training and it takes a long time, the accuracy is less controllable. Here we will study how to use the replacement materials and the results of quality improvement through statistical data, bad analysis, and bad countermeasures, and establish relevant education and training to prevent it, not only improve the quality, but also save costs. The method can be used to detect the cause of the defect in advance and prevent it.
