$50{\mu}m$ Microlens 패턴 금형의 미세사출성형 전사성과 전광특성 기초연구
A Basic Study of replication and brightness for micro injection molding with ${\sim}50{\mu}m$ micro-lens pattern mold
초록
Micro-lens patterned micro-mold fabrication method for Light Guiding Plate(LGP), kernel part of LCD-BLU(Back Light Unit), was presented. Instead of erosion dot pattern for LGP optical design, micro-lens pattern, fabricated by LIGA-reflow process, was applied. Optical pattern design method was also developed not only for negative pattern LGP, but also positive pattern LGP. During injection molding process, experimental study was conducted to improve replication quality and brightness of
