In edge lighting light guide plate (LGP), because of the point source characteristics of LED, the luminous intensity at the center is the largest. When the light is coupled into LGP, due to the short distance between the source and the scattering area, hot spots problem will appear on LGP, if we don't have any treatment in front of LGP. Thus it is urgent to solve this problem at present.
A novel type of composite structure is proposed in this thesis, using optical simulation software SPEOS in the design of composite angle of V-CUT and specific location on groove. By composite angle of V-CUT and groove design, it allows more light to reach wide angle. There are some arranged dots on the surface of the groove, which can improve the distribution of light and reduce the hot spot phenomenon. Finally, in A/P ratio equals 0.15 case, this scheme successfully enhances the uniformity from 36.4% to 76.3%.
