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 improve the performance of systems and apply the dynamic display technology, a designing method of light guide plate (LGP) module for direct illumination is presented, one LGP structure based on the method is also demonstrated, and then the simulated results of module indicates the uniformity is larger than 80%, which can satisfy the need of illumination. The simulated result of large LGP made by many modules for dynamic display is showed, and the experiment of light guide plate module is demonstrated.
