发明名称 LIGHTGUIDES HAVING ENHANCED LIGHT EXTRACTION
摘要 Lightguides, devices incorporating lightguides, processes for making lightguides, and tools used to make lightguides are described. A lightguide includes light extractors arranged in a plurality of regions on a surface of the lightguide. The orientation of light extractors in each region is arranged to enhance uniformity and brightness across a surface of the lightguide and to provide enhanced defect hiding. The efficiency of the light extractors is controlled by the angle of a given light extractor face with respect to a light source illuminating the light guide.
