Abstract
Optical performances of micro-pyramid arrays were simulated by ray tracing technique for the application of backlight unit of LCD. The angular distribution of the luminance and the on-axis luminance gain depended on the apex v angle, the refractive index, and the density of micro-pyramids. The on-axis luminance reached a maximum when the apex angle was 90 degrees. It also increased as the density and the refractive index of micro-pyramids increased. The present result showed that highly-efficient optical Sheet might become realized by adopting micro-pyramid array and corresponding development of manufacturing processes.
