Abstract

Light guide plate (LGP) plays an irreplaceable role in backlight module of liquid crystal display (LCD) systems. Based on interactive design of Gtools and Tracepro, we propose an effective design method of scattering dots array for LCD backlight in this paper. This method first initializes the scale of the scattering dots in Gtools, then evaluates illumination distribution in Tracepro, and finally determines the array layout of the scattering dots from the interactive optimization between Gtools and Tracepro. This method can flexibly adjust the light emission in each sub-area of the LGP, which has scientific significance and practical value in some ways.
