Fabrication of a prism structure on light guide plates with UV roll-to-plate imprinting process

摘要

As the demand of multiple functions optics devices fabrication, conventional methods such as injection molding and hot embossing to fabricate light guide plates (LGPs) with the prismatic structure become difficult and unsuitable; so we developed a roll-to-plate UV imprinting lithography (RPIL) process for fabricating the prismatic structure on light guide plates (LGPs). Using the proposed process, the prismatic structure on the LGP achieved a formability rate 97%, and the luminous gain rate of the imprinted LGP exceeded 1.6, this is almost the same as that of 3M's prism film. This study demonstrates the potential of our proposed process for fabricating the prismatic structure on the LGP.
