Abstract
Driven by E-book readers in recent years, the application market of E-paper has been growing rapidly. Moreover, featuring lightweight, slimness, low power consumption and flexibility, E-paper has attracted many enterprises to commit huge resources to the application of new technology. With the trend of energy-saving and the advantage for lengthy reading, E-paper is gradually regarded as a substitute for conventional papers. The latest E-paper display of second generation is currently unreliable in the environment test of high stress, and fails to pass the requirement of mass production, which means the current product is unable for consumers to use at length. According to the development experience of related products, the efficiency of improvement is slow if designers adjust the parameters by trial-error method. Worse, designers occasionally have difficulty in finding the optimal set of parameters or even have yet to confirm the key parameters, so that the development schedule of new product is delayed. This study first employs the combined methodology of FMEA and Taguchi methods, which suits the reliability improvement in TFT-LCD products. The main object of the study is to improve the reliability of E-paper display. The ideal attributes of product reliability are first delineated, then the fundamental parameters, which influence the reliability, are figured out by FMEA method; afterwards, the optimization and effectiveness of parameter standards are achieved by Taguchi method. The methodology of this study provides researchers with systematic framework to conduct experiments, and the approach of parameter design, additionally, contributes the improvement to the case of study in a short time. The latest generation of product can be launched sooner in the market and meet customer needs by successfully shortening more than half a year in the development period.
