To determine the quality characteristics is the first step in Taguchi method. Since the purpose of this work is to discuss the influence of microstructures in the incidence plane on the luminance uniformity near the incidence plane of a LGP in a LED BLU. The luminance uniformity in the region near the incidence plane is assigned as quality characteristics in Taguchi method. The nominal-the-best is chosen as the ideal function of quality characteristics.
