碩士 === 南台科技大學 === 工業管理研究所 === 99 === Electronic industries are the main economic sources in Taiwan. TFT-LCD is one of the electronic industries and it plays an important role in the industries. There are a lot of competitors in TFT-LCD industry around the world and the production cost of TFT-LCD is extremely high. To reduce its production cost and increase profit becomes the primary concern of the management. In order to manufacture the TFT-LCD to satisfy the demands of the consumer’s market, every company is trying to search for the optimal production process parameters by experiments continuously. The best product quality can only be guaranteed through the validation of the optimal production process parameters. However experiments consume much money and time. The more experiments to search for optimal production process parameters, the less profit for the company. Under this situation, how to perform fewer experiments to search for the optimal parameters is a very important topic. This research applies Taguchi Methods and Central Composite Design (CCD) on the process of grinding color filter which is the critical component affecting the quality of TFT-LCD. This research utilizes fishbone diagram to obtain important causes of the color filter grinding process and compares Taguchi Methods with CCD by calculating the correlation coefficients among the deign variables of the two designs. We finally decide to apply CCD on the search of the optimal process parameters. Also we validate the estimated model and optimal process parameters through confirmation runs.
