针对现有的量子点薄膜液晶显示背光技术中存在的材料利用率低和光学效率不高的缺点，提出了直接在导光板上制备量子点微结构的方法。新的背光架构由蓝光发光二极管(LED)激发量子点形成高显色性的白光。根据搭建显示背光系统模型，研究光线追踪的仿真模拟和光学参数优化，证明新结构的量子点背光具有高出光效率和低成本的优点。实验与理论结果相一致。

For low material utilization and low optical efficiency of the quantum dots thin film transistor liquid crystal display (TFT-LCD) backlight, a new model is proposed to form quantum dot micro structure in light guide plate. The new structure make the blue light emitting diode (LED) pump into high color rendering index (CRI) white light. The backlight system is built, and the study on ray tracing simulation and parameter optimization shows that the new quantum dots backlight has the advantages of high optical efficiency and low cost. The experimental and theoretical results match well with each other.
