碩士 === 國立高雄第一科技大學 === 系統資訊與控制研究所 === 99 === Thin Film Transistor, liquid crystal display flicker of the phenomenon of the LCD module manufacturing process a common problem, root cause in the LCD manufacturing process on two glass electrode substrate produced by the middle of the gap parasitic capacitance (Cgs), the entire surface of the glass substrate followed by inconsistent gap voltage difference caused by the voltage difference is the reason for making the panel flicker. In recent years the panel quality of customer demand have become high increasingly , so the flicker from the past to improve the panel factory manual adjustment of the Vcom voltage (positive and negative polarity in the middle of the LCD threshold voltage), advanced digital technology to adjust Vcom voltage, In this way the factory can reduce the number of flashes to adjust working hours, but also reduce the company''s production costs effectively, but the digital system in the human-machine interface Vcom adjustment has not been reached on the optimal value,in view of this, this study, Taguchi method ( Taguchi Method) and dual response surface method (Response Surface Methodology, RSM), the system flicker to adjust time and adjust the rate optimization, the quality characteristics of the target to achieve the best of purposes, as to enhance the quality and efficiency of production methods considered one.
