The liquid crystal displays (LCDs) possess the most mature technology and best consuming competitiveness in the flat panel display (FPD) industries. Of all the LCDs, thin film transistor-liquid crystal display (TFT-LCD) keeps some real advantages. It is thinner, smaller and lighter than other displays and has low power consumption, low-radiation, high-contrast and high-dpi at the same time. Hence, the TFT-LCD panel is widely applied in daily electronic products, and the demand for the TFT-LCD panel increases. The product life cycle of the TFT-LCD panel is gradually getting into the mature stage, and meanwhile, Taiwan
