摘要
En 中文
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.
