Abstract

An optical sheet with microlens array (MLA) is designed and fabricated as a substitute for the prism sheets of LCD backlight. Using photoresist thermal reflow, MLAs were fabricated on PET film with thickness of $100{\mu}m$, and we measured the change of MLA profile in terms of exposure time, reflow temperature and reflow time.

PET 필름 위에 LCD 백라이트의 프리즘 집광시트의 역할을 대체 할 수 있는 microlens array(MLA) 시트를 설계하고 제작하였다. Photoresist thermal reflow 공정으로 두께 $100{\mu}m$ PET 필름 위에 MLA를 제작하였고, 노광 시간과 reflow의 온도, 시간 등의 변수에 따른 MLA의 형상 변화를 측정하였다.
