提出使用可变散射点代替单一点来创建优异的导光板。本文实现了超快激光加工在散射点上的应用，并通过仿真和实验验证了其均匀性和光利用率。这些点的性能不仅取决于密度和分布，还取决于点的具体特征。证实了合适的形状和具有更好散射效果的更小的点的概念。使用飞秒激光加工可以实现具有任意特征的高质量微点，并且平行光束可以保证微结构阵列的未来吞吐量。
The use of variable scattering dots to replace simplex dots is proposed to create an excellent light guide plate. The application of ultrafast laser processing on scattering dots is implemented in this paper, and the uniformity and light utilization are verified by means of simulations and experiments. The performance of these dots depends not only on the density and distribution but also on the specific features of the dots. The concept of a suitable shape and smaller dots with better scattering effects is confirmed. The use of femtosecond laser processing can achieve high-quality microdots with arbitrary features, and parallel beams can ensure the future throughput of microstructure arrays.
