Abstract:	LCD液晶本身並不發光，必須由LED/CCFL背光模組提供足夠且亮度均勻的光源，才能使LCD可正常的顯示影像，而背光模組中能提高亮度之主要零組件為增亮膜(稜鏡片)。本論文將對增亮膜所構成之相關參數 : 稜鏡高度、稜鏡結構材質、稜鏡角度及底部基材材質做分析，以田口實驗設計法找出影響實驗最大的因子，並得到一組最佳條件，此最佳條件之亮度將比市售之3M BEFII單片輝度增益10%以上，而雙片疊加時，輝度更可增益30%以上，此結果可能為目前市場上之稜鏡片增亮膜所無法達到的。The liquid crystal of LCD (liquid crystal display) can’t display itself , it needs LED/CCFL back light module to provide enough and uniform brightness and let LCD display normally. In the backlight module , brightness enhance film (prism sheet) is the major part to enhance the brightness. The paper analyzed the effect of the variation of its structure parameter , such as prismatic thickness , prismatic material , prismatic angle and substrate. With the Taguchi method finded out the most important factor and select the best condition of the experiment. The brightness of this condition is enhanced above 10% than 3M BEF II with one prism sheet. With this condition , the brightness is enhanced above 30% than 3M BEF II to cross two prism sheets.It maybe the highest brightness of prism sheet now.
