摘要

针对导光板(LGP)网点分布设计进行了研究，提出了以导光板网点最佳平均密度(BANDD)范围的定义来阐述导光板网点的最优化设计。根据导光板导光理论建立背光源模组(BLM)的光学模型，并仿真了模型在不同均匀网点密度(NDD)下性能的变化，结果表明在0.1~0.4 之间的网点密度其出光效率与均匀性达到相对平衡。进一步对0.1~0.4范围内的网点密度进行网点排布优化以提高其均匀性，仿真结果表明网点密度在0.2~0.35范围内的网点可以达到设计阶段对均匀性指标的要求。加工了相应的实验样品，验证了导光板最佳平均网点密度范围在0.25 左右，与理论相符合。该研究结果对于实际开发具有一定的指导意义，将有助于加快背光源模组的开发进度，减少开发版次，并降低背光源模组的开发成本。

Abstract

The definition of best average netted dot density(BANDD)is proposed based on the research of the pattern of the netted dot for light guide plate(LGP), in order to elaborate the optimal design for the netted dot of LGP. A backlight module(BLM) is modeled in the light simulation software based on the theory of LGP guiding light, a group of differently uniform netted dot density (NDD) are applied in the model to test the effect on performance, the results indicate that the NDD from 0.1 to 0.4 relatively balances efficiency and uniformity. Further more the layout of the netted dot in the scale mentioned above is optimized to improve the uniformity; the results of simulation state clearly with the NDD from 0.2 to 0.35 can reach the requirement of uniformity in development stage. The corresponding experimental samples are made; the result of the experiment demonstrations that the BANDD is located in 0.25, it agrees well with the theoretical predictions. It has certain guiding significance that the conclusion of the study are applied in the actual development, and will accelerate the procedure of BLM and reduce the counts of designing editions, and cost down the development expense of the BLM.
