| 摘 要： | 目前，市场上流行的手机背光源的导光板基本上为单面网点(球型微透镜阵列)的结构。文章介绍了一种新型手机用导光板的设计，其采用一面为网点结构，另一面为轮廓渐变的V-槽形结构的自由曲面，以使导光板的配光更加合理。模拟结果显示，导光板照度比单面网点的导光板要高出1倍左右。采用这样的结构，背光模组中至少可以少用一层3M公司的增亮膜(棱镜膜)．倬背光樽组的成本有效降低．

| Abstract: | Having a microlens array on one side of the lightguide plate is now widespread in cell phone backlight systems. This paper describes a new design for the cell phone lightguide plate, which uses microlens array structure on one side and a progressive V-cut freeform surface on the other side. The illumination distribution of the lightguide becomes more reasonable. The results of the simulation show that the illumination of the lightguide plate is double that of a plate with only a microlens array in one side. If this lightguide is adopted, a layer of 3M brightness enhancement film can be reduced. |
