选取LED作为侧入式导光板光源，利用光的全反射、折射和光通量守恒定律等光学理论推导出变距离（网点大小相同）网点的排布规律，有效解决了网点的设计难题。同时推导出LED排列间距临界公式，有效消除了由LED的排列间距引起的强弱光区交替现象。通过光学软件TracePro，建立相应的物理模型。经过反复实验，取得最佳参数，均匀度高达93％，超过80％，满足实际对均匀性的要求。

With LED selected as the light source of side-incident light guide plates, it solves the difficult problems with the design of scattering netted dots with various distances on light guide plates of side-inci-dent LED backlight efficiently by deriving a rule of scattering netted dots arrangement, based on the op-tics theories such as total reflection, refraction and the principle of luminous flux conservation.The criti-cal array pitch of LED is deduced, which can effectively eliminate the different light intensity caused by LED arrays.Then, the optical design software TracePro was used to establish the physical simulation model.Through repeated experimental investigation, optimum parameters have been obtained.The simu-lation results show that the illumination uniformity of the designed light guide plate is close to 93%( over 80%) , which satisfies the requirements of the national illumination standard.
