提出了一种用于导光板设计的微棱镜一维密度生成方法。它有三个参数，包括微棱镜的宽度，细胞的比例和概率值。在计算新密度后，我们将其应用于动态低差序列法来生成微棱镜分布。我们在光学软件中制作了2.7英寸、7英寸和14英寸的模型。仿真结果表明，光源的亮度均匀度在89.9% ~ 92.2%之间，光能利用率在79.5% ~ 80.0%之间。这种新的密度生成方法在中小型BLU设计中是可行的。通过在初始化中代替确定棱镜数，也有助于缩短设计周期。
This paper proposes a new 1D density generation method for micro prisms applied in a light guide plate (LGP) design. It has three parameters, including the width of micro prisms, the ratio of cells and the probability values. After calculation of the new densities, we applied it to a dynamical low discrepancy sequences method to generate the micro prisms distribution. We build models of 2.7 inches, 7 inches and 14 inches in the optical software. Our simulation results indicated that the luminance uniformity ranged between 89.9% and 92.2%, and the light utilizations ranged between 79.5% and 80.0%. This new density generation method is proved to be practicable for middle and small size BLU designs. It also helps to shorten the design period by substituting the determination of the prisms numbers in initialization.
