Fabrication of Light Guiding Plate of Double-Side Hot-Embossing

Abstract:

Generally, the light guiding plate is fabricated by injection molding. Polymethyl methacrylate (PMMA) material is used to fabricate the light guiding plate. In order to reduce the space of backlight, the light guiding plate is based on double-side microstructures by using MEMS and hot-embossing technologies. From the experimental results, the minimal illumination is 355 lux and the average illumination is 368.1 lux, the uniformity of illumination is 0.08. The novel integrated light guiding plate is achieved a uniformity of distribution, without any optics sheets. In this paper, non-prism LGPs, micro-prism LGPs, and the double-side hot embossing LGPs are fabricated.
