摘要
In this research, a new developed optimization method for light guide plate design is proposed in order to achieve its exiting-light uniformity by varying the light-scattering microstructure sizes or pitches at different areas of a liquid crystal display (LCD) light guide plate. The light-scattering hemispheric microstructures on a light guide plate are studied in this paper due to less light absorption compared to the conventional V-cut pattern design. The results show success in uniformity. To validate the effectiveness of this design method on the improvement of exiting-light uniformity, the "advance system analysis program" (ASAP) simulation is performed. Based on the proposed design method, it is illustrated that the exiting-light uniformity significantly improves by more than 13% for the case study.
