45.2: Moiré-Free Collimating Light Guide with Low-Discrepancy Dot Patterns

the notion of discrepancy, we developed a new technique for generating uniformly distributed dot patterns. We designed and prototyped a light guide having prismatic grooves and micro scatterers on the surface. We experimentally confirmed that the new pattern of the micro scatterers effectively prevents moire patterns, and improves the luminance homogeneity.
