Abstract

We have proposed a highly scattering optical transmission (HSOT) polymer for use as a high luminance light source medium. This polymer contains specified internal microscopic heterogeneous structures for controlling light scattering properties. A LCD backlight using the HSOT polymer has twice the brightness of the conventional transparent PMMA-based backlight because of multiple scattering phenomenon inside the HSOT polymer. In this paper, such a light scattering phenomenon was quantitatively analyzed by a ray tracing based on Mie scattering and Monte Carlo simulations.3) Subsequently, we proposed the new HSOT backlight system having higher luminance and uniformity of white color illumination.
