BLUNT TIP PRISM FILM AND METHODS FOR MAKING THE SAME

摘要

In one embodiment, a film can comprise a transparent substrate comprising a plurality of prism structures, wherein the prism structures have a blunt tip having a tip length of 250 nm to 2,000 nm. The film can be used in various applications, such as back light displays. In one embodiment, a method for forming a master for a film can comprise ion beam etching a diamond tip to form a blunt tip having a tip length of 250 nm to 2,000 nm, and forming negatives of prism structures into a master using the diamond tip.
