The research used the LCD panel price and quantity data applied on mobile phone from Jan. 2003 to Dec. 2008. After defining the variables, we used 24 sets of seasonal data based on the time period to do the regression. The outcome of the research shows the market share of TFT-LCD reached 64.78% in 2008/Q4. The market share of other technology categories didn't increase obviously in the same period. About the price analysis, the price range of LTPS TFT-LCD was the largest compared with other technology categories. The category of LTPS TFT-LCD had the highest average price and second high price standard deviation. It was shown that LTPS TFT-LCD had lower technology maturity than other technology categories, and the supply and demand of LTPS TFT-LCD changed drastically in short time period. Besides, the result of regression model shown the mobile phone panel price elasticity of demand was 1.170 and fell on elastic range. The mobile phone panel was high sensitive when the demand quantity of changed larger than the price. The result shown that we could increase the quantity of demand obviously when we reduce the price of mobile phone panel. If we could reduce the total cost of the panel, it may have the same profit when we reduce the price to increase the quantity of demand. Otherwise, the coefficient of variable "GNI(us)t" was 0.274. Based on the log-form regression model, the income elasticity of demand was 0.274 and fell on the range of "Necessities".
