Abstract
Along with the huge scale of LCD TV demands in the markets, the only one way to acquire market share is doing research and development with new technology. Notwithstanding the demand scaled LCD TV has serious problem of color shift. In the past, research and development staff tried to maximize its parameter by try and error method, which delay the schedule of new product development with inefficiently improvement. Therefore, there are only high end LCD TVs with Multi-Domain Vertical Alignment ability can reduce the extent of color shift, which is also predicted to be the elemental function of big size LCD TVs. The purpose of this study is to improve color shift problem of LCD TV by performing Design for Six Sigma method. With the implementation of DMADV of Design for Six Sigma, this study finds out design ideas with the implementation of TRIZ. Moreover, this study executes improvement by optimizing the pixels electrode structure according to the adoption of Taguchi Method. Finally, the project has reached a significant improvement of color shift rapidly, upgrade the quality of production, and apply for patent. The contribution of this study is that research staff has improved color shift by implying DFSS, which bring forth extra net income of $530 million New Taiwan Dollars, and enlarge the market scale of TFT LCD TV.
