Design and Simulation of Scattering Netted Dots on Light Guide Plate of Side-incident LED Backlight
摘要
Abstract
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.关键词
