We describe an advanced highly scattering optical transmission (HSOT) polymer backlight system that has shown twice the brightness of a conventional transparent system in spite of its having a thinner backlight. The HSOT polymer that contains optimized heterogeneous structures produced homogeneous scattered light with forward directivity and sufficient color uniformity. Although it was thought that polymers for light-guide plates (LGPs) must be transparent to minimize scattering, we have come to the conclusion that the HSOT polymer, which is not an absorping medium but a scattering medium, is a more suitable medium for LGPs.
