This research uses Ink-jet printer process to fabricate microlens on the bottom of a LGP in a fast and cost-effective way. Compared with typical dot printing method, Ink-jet printing is able to save 50% material consumption. In addition, the microlens with UV-curable epoxy could be well controlled in the radius, contact angle and arbitrary arrangement. A 20×20cm2 LGP can be fabricated with desired microlens pattern within 10 seconds, which exhibits a potential to apply ink-jet process upon the high-speed mass production.
