Paper Abstract

This research points out the brightness field and luminance distribution of the microstructure of a light guiding plate by micro injection molding (MIM) and micro injection-compression molding (MICM). The process of a light guiding plate includes photo-etching, micro molding techniques (MIM and MICM), and optical field measurement. The results show that the luminance of microstructure of light guiding plate made by MICM is better than those made by MIM. The results also indicate the most important processing parameter is the mold temperature for the luminance distribution of light guiding plate whether made by MIM or MICM. The maximum luminance of the light guiding plate is the 80 Nit (cd/m2) on micro molding. The brightness field distribution of light guiding plate made by MICM is more uniform than those made by MIM for the same processing parameters. The micro injection-compression molding is a more suitable process than micro injection molding for the fabrication of light guiding plate on a backlighting unit.
