LCD backlight unit의 고분자 산란형 도광판에 관한 연구

초록

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. Moreover, to improve the uniformity of the conventional HSOT backlight unit, We employed additionally dot patterns to obtain backlight units with high luminance and good uniformity. For the proposed structure, we calculated the light transmission behavior. As a rusult, we can obtain a bright and uniform backlight unit for a large size LCD panel of more than 12 inch.
