  • LUMINANCE-ENHANCED FILM
    Publication number: 20100195234
    Abstract: Disclosed is a luminance-enhanced film, including birefringent island-in-the-sea yarns which comprise island portions and sea portions, each composed of a specific material. Accordingly, unlike conventional stack-type luminance-enhanced films, the luminance-enhanced film of the present invention comprises birefringent island-in-the-sea yarn, as a layer, in the sheet, thus considerably improving luminance without forming a plurality of layers. In addition, several hundred layers are not laminated on one film and the film can be easily fabricated at considerably reduced costs. Furthermore, the luminance-enhanced film has considerably more birefringent interfaces, as compared to films fabricated by conventional methods wherein birefringent fibers are incorporated into sheets, thus considerably improving luminance-enhancement effects and being industrially applicable.

  • LUMINANCE-ENHANCED FILM
    Publication number: 20100195233
    Abstract: Disclosed is a luminance-enhanced film, including birefringent island-in-the-sea yarns, whose island portions are grouped, based on two or more spinning cores, present in a sheet. The luminance-enhanced film causes formation of an optical modulation interface between island portions and sea portions, thus maximizing optical modulation efficiency, as compared to conventional birefringent island-in-the-sea yarns. The birefringent island-in-the-sea yarns of the present invention are free of aggregation of island portions in the center thereof, although the number of island portions is 500 or more. As a result, the birefringent island-in-the-sea yarns maximize an optical modulation interface area, and thus considerably improve optical modulation efficiency, as compared to conventional birefringent island-in-the-sea yarns including one spinning core.
