摘　　要：光散射聚合物(HSOT)导光板与传统导光板相比具有亮度更高均匀性更好等优点,其性能受材料的影响十分明显。通过蒙特卡罗方法进行光学仿真模拟考察不同材料的导光板照明光线的均匀性差别,研究了光散射聚合物导光板的光学性能受其中掺杂粒子的材料折射率、粒径、浓度的影响规律。通过比较不同材料参数的聚合物导光板的光学性能差别,总结出光散射聚合物导光板的材料设计方法。A highly scattering optical transmission （HSOT） polymer light guide plate （LGP） in backlight of liquid crystal displays （LCDs） have succeed in applying high brightness and uniform illumination . The optical character of the HSOT LGP is depend on its material. By using the Monte Carlo ray tracing method a sequential ray- tracing and modeling simulation program is proposed. The different optical characters between different material of LGP is depended on the percentage, diameter and the material of the scatter particle. By preparing the different characters between different material parameter, a design method of HSOT LGP could be proposed.
