Abstract:

This paper proposes a new light guide plate design with a rectangular side entering type distribution and arbitrary number of LEDs as the light source to reduce the times of backlight module revision of LGP network design,development time and cost in the actual production.The simulation model of the light guide plate is established using the TracePro software.The simulation diagram of illumination is obtained by inputting the theoretical calculation formula and the use of ray tracing function.The design of the preliminary theoretical calculation of distribution network is optimized by the optimization module of texture optimizer on the TracePro platform.A uniformity of 87% is achieved in the model with three LEDs as the light source,which is in line with national standards.
