Paper Abstract

An integrated light guide plate(LGP) using micro optical technique is presented in this paper. Micro-prisms are fused on the bottom surface which replace the plane reflective film at presented. By changing the bottom angles of micro-prisms, the relationship between the bottom angle and the direction of peak luminance is analyzed systematically. When the direction of peak luminance is concentrated on vertical angle(90°), the vertical direction luminance of LGP without structure on the top surface is already closed to the 3M backlight module. while in the LGP which fused the micro tapers with tiny concave on the top surface, the illuminance and the vertical direction luminance is about 2.28 times and 1.09 times compared to the 3M backlight module respectively. The result shows that the novel integrated micro optical LGP can substitute for 3M crossed prism films and accorded with the tendency of integration ,frivolity and high brightness in backlight system.
