Paper Abstract

A five-inch light guide plate by arranging special cone dots on the surface of optical polycarbonate film was designed. Then an optical model was built by using TracePro and the luminance distribution of the light guide was simulated by using ray tracing method to achieve an efficient and uniform radiation of light from the light-guide. The above light guide was fabricated by roll to roll hot embossing process instead of injection molding. The fabrication of the hotembossing mold was investigated. Finally, a 5 inch light guide with the average luminance greater than 3000 cd/m2 and the uniformity above 80% was fabricated. This process will contribute to the production of an ultra slim light guide in the future.
