Fabrication of Gapless Dual-Curvature Micro-lens Technique

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.
