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.
