本研究提出了一种新的导光板优化设计方法，通过改变液晶显示（LCD）导光板不同区域的光散射微结构尺寸或间距来实现导光板的出光均匀性。本文研究了导光板上的光散射半球微结构，该微结构与传统的v形切口设计相比，吸收光较少。结果表明，一致性是成功的。为了验证该设计方法在改善出光均匀性方面的有效性，进行了“超前系统分析程序”（ASAP）仿真。实验结果表明，采用该设计方法后，出射光均匀度明显提高13%以上。
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.
