發光二極體(Light Emitting Diode，LED)在液晶顯示器(Liquid Crystal Display，LCD)背光模組最具前景及發展性，但是傳統砲彈型LED光源屬於點光源發光較不適用於大尺寸的面板，因此本研究改變原本LED的封裝並設計製作出雙曲率無縫微透鏡(Gapless Dual-Curvature Micro Lens，GDML)，而光線經過填充率愈高的微透鏡後均勻度會改善，此外探討配置光罩圖形對輝度的影響，所以使用TracePro軟體模擬比較六角、三角和雙曲率圖形的無縫微透鏡輝度值。
利用微機電技術製作雙曲無縫微透鏡，首先將大小交錯的光罩圖形轉移至所需的基板上，以鎳鈷電鑄後的模具熱壓於金屬材料上作為模仁，再將模仁填充UV膠材料而形成微透鏡，成品不僅擁有不同曲率的特性而且填充率也可以達到100%，此製程的優點只需使用一次電鑄的程序且能大量快速地複製成品，而且二次翻印後的收縮率皆小於0.5%，微透鏡搭配封裝於LED晶粒，在正向光源上的輝度誤差值在1.2%和在均勻度上也有所效果。

Light emitting diode (LED) will have development in liquid crystal display (LCD) backlight. Nevertheless, the point source of LED is not suitable for large size panel. Therefore, this research will change the package which is bullet type and design gapless dual-curvature micro lens (GDML). Using the optics software TracePro is simulation luminance to compare of hexagon, triangular and dual-curvature micro lens, and fabrication of the better size. We can get metal model using micro-electro-mechanical systems (MEMS) technology after electroforming and hot embossing. The micro lens is formed by UV cure in metal model. It has different curvature and fill factor 100%. The advantage of electroforming is can manufacture a lot of product fast with high performance. The shrinkage rate is less than 0.5%. The collocation package of micro lens and LED chip can improve intensity and uniformity.
