P‐96: Microlens Array by Ink‐Jet Technology for LCD Backlight Applications

Abstract

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.
