为了进一步提高大尺寸液晶照明系统的综合性能,并符合动态显示的技术要求,提出了一种直下式导光板模块化设计方法,并以其作为指导,设计了一种采用导光板的直下式照明结构模块。对模块进行了照明仿真计算,其均匀性大于80%,满足大尺寸液晶面板的照明需求。在该模块拼接的基础上进行了动态显示的模拟,并对单个导光板模块进行了实验的验证。
In order to further improve the overall performance of large-size liquid crystal lighting system, and in line with the dynamic display of technical requirements, put forward a direct type light guide plate modular design method, and use it as a guide, the design of a light guide plate with direct type lighting Structure module. The module has been lighting simulation calculations, the uniformity of more than 80%, to meet the lighting needs of large-size LCD panel. The simulation of the dynamic display was carried out on the basis of the splicing of the module, and the experiment of the single light guide plate module was verified.
