Abstract

See full text

A LGF roll-to-roll manufacturing includes the steps of: preparing a first optical layer with a first surface and a second surface; mechanically extruding a first integrated microstructure on the first surface of the first optical layer; subsequently coating a second optical layer on the first or second surface of the first optical layer; and curing the second optical layer to directly form a second microstructure on the first or second surface of the first optical layer. The first integrated microstructure and the second microstructure are separately formed at a time to provide a light guide film structure. In an embodiment, an additional optical layer is provided on the first optical layer.
