Abstract

we analyzed multiple ray tracing in the highly scattering optical transmission(HSOT) polymer plate by means of the Monte carlo simulation. Light transmission behavior in the light guide was simulated by a 3-dimensional ray tracing program considering scattering angle given by the Mie theory and mean free path. To improve the uniformity of the conventional HSOT backlight unit, We employed additionally dot patterns. For the proposed structure, we calculated the light transmission behavior and obtained a bright and uniform backlight unit for a large size LCD panel of more than 12 inch.
