BLU(Back Light Unit) is one of kernel parts of LCD(Liquid Crystal Display) unit. New 3-D micro-lens pattern for LGP(Light Guide Plate), one of the most important parts of LCD-BLU, was proposed and applied to injection mold. Instead of dot pattern made by chemical etching or laser ablation, the SCS(Slanted Curved Surface) micro-lens as micro-optical unit of LGP was applied and designed for optical CAE simulation. The method of optical design using optical CAE simulation for the SCS micro-lens, the new fabrication method of micro-mold with SCS micro-lens pattern was introduced and basic geometric aspects of the SCS micro-lens for LGP pattern was discussed.
