Generally, the traditional LGP is fabricated by injection molding technology. MEMS and hot embossing technologies are applied to fabricate the integrated LGP in this research. The concentric circle v-cut structure and the pyramid arrays are constructed on the integrated LGP. Therefore, the new backlight system could be simplified to use only one integrated light guiding plate without any other optical sheets. The concentric circle light guiding plate (CCLGP) can eliminate four optical sheets (including two diffusive sheets and two pyramids sheets) in backlight system, so it can save the space and the process cost of backlight system
