| Summary: | 碩士 === 亞洲大學 === 經營管理學系碩士在職專班 === 97 === The progress of the communications rapid technological advances, information technology increasingly popular and Liquid Crystal Display (Liquid Crystal Display; LCD) is it era the messages and communicate with each other important interface, which liquid crystal display of light, thin and low power consumption, low-power advantages, the daily life of the widely used electronic goods, comply with the unit of information technology development, liquid crystal display of the application in just a few ten years, leaping show the growth of the growing demand liquid crystal displays with Taiwanese Panel industries to German product life gradually came to mature, faced with South Korea and Japan's fierce competition, it sustained efforts to cut costs is the current LCD industry is a need to fully and actively.
The Assembly of the LCD important in process, however, the study subject six sigma management methods and in the process innovation concept, to improve LCD assembled in process quality, in the project management improvement steps(define measure analyze improve control, DMAIC), Implementation of a quality improvement, through experimental design(Design of experiment, DOE) The analysis techniques, and the identity of ways and means to identify variations in the process of several thereby introducing testing analysis, identify important significant factor implementation of pilot improve, enhance LCD assembled in process quality. six sigma standards margin improvements practices, both in the improvement within the system (Definitions, measurement, analysis, improvement and control) or is outside the system improvement (Definitions, measurement, analysis, design and check ), which will be followed by the definition of five steps to implement flow improved project that a company all classes and sector can clear six sigma and practices of the benefits, common as the company's sustainable development.
The research to A companies, for example, use of six sigma management of the project improve steps to identify LCD assembled process low-quality reasons, to check the analysis factor experimental design was the best process. The study indicated liquid crystal displays by assembled by ratio of bad factor of experimental design implementation LCD assembled process improve, improving y1 and y2 total LCD assembled bad rate 2.76 percent, improve y1 and y2 assembled its LCD bad rate has dropped 0.78 percent. Therefore, the inspection six sigma management and process innovation would effectively upgrade product process quality, save costs of production, thus increasing the business profits and competitiveness.
