LUMINANCE ENHANCEMENT FILM CAPABLE OF PREVENTING ISLAND BONDING WHEN RAPIDLY INCREASING THE NUMBER OF ISLAND COMPONENTS OF BIREFRINGENCE SEA-ISLAND FIBER

摘要

PURPOSE: A luminance enhancement film is provided to improve a mow phenomenon, thereby preventing an agglomeration phenomenon in the center of sea-island fiber.;CONSTITUTION: A luminance enhancement film includes birefringence sea-island fiber in order to generate optical modulation effects in the inside of a base. A core part(510) is arranged in the inside of the birefringence sea-island fiber in order to prevent island bonding. The birefringence sea-island fiber includes a plurality of island component groups(520,530) arranged in a radial shape from the core part. One or more ring-shaped boundary parts are arranged from the core part in the luminance enhancement film.;COPYRIGHT KIPO 2012
