We have developed a highly scattering optical transmission (HSOT) polymer, and have succeeded in applying it to a highly efficient backlight in liquid crystal displays (LCDs). In the present work, a multiple scattering modeling simulation has been developed. Also the effects of adjacent particles inside the HSOT polymer are demonstrated. Although Mie scattering theory is based on the assumption that there exists one particle, light scattering intensity profiles are extended by adjacent particles in measurement data. In order to improve the multiple scattering modeling simulation, light scattering intensity profiles calculated by Mie scattering theory are modified by using the experimental correction function. It follows that the numerical calculation improved by taking account of the adjacent particles has precisely reproduced multiple scattering phenomena inside the HSOT polymer. Based upon the results of multiple scattering analysis, an optimal design has been developed and applied to an LCD backlight system. By altering the internal particle condition, uniformity of color and brightness on the top face of the backlight can has been achieved.
