Abstract

We propose a highly-efficient backlight that requires no optical films with a polymer containing spherical particles of micron size. The backlight developed is provided with microprisms at the bottom surface, which can reflect the incident light directly into the front direction. A modeling simulation program, employing a Monte Carlo method based on Mie scattering theory, has optimized both the prismatic condition and the multiple scattering characteristics. We confirm that a uniformity of brightness can be achieved without using any optical films, resulting in a high optical efficiency of 62%.
