碩士 === 國立勤益科技大學 === 工業工程與管理系 === 98 === The liquid crystal display (LCD) industry is not only the fastest-growing domestic business in recent years resulting from the advancement of multimedia applications and data services for mobile devices，it also possesses the competitive edge on global markets。LCD has characteristics such as full-color，slim-design，low-cost，low power consumption，dynamic display and zero image residual， however， as LCD manufacturing technology covers various areas like semiconductor，liquid crystal chemistry and optical imaging，all these make the manufacturing process of LCD industry a high responsible task。In short，the manufacturing technology of LCD industry still has a lot of room for improvements。 This thesis focuses on the strength of glass for LCD。As the product life cycle of the panel for mobile device is extremely limited，mobile device companies must take a variety of approaches in product design，naming light-weight，thin-body and low-profile，thus makes the panel for mobile devices become even thinner。Therefore，the thickness of panel is shirking from an early age of 1.1mm to 0.3mm，even 0.2mm in these days。Because the mobile device will be break easily by dropping and extruding，so the customers start to request the strength quality from thickness 0.4mm of products。This thesis use a TFT-LCD factory as an example。The case company use DMAIC approach of six-sigma via customer’s voice with DOE and QC analysis methods to find out the important factors，then to improve process capability and production yield rate。
