Abstract

In this paper, we propose an integrated micro-optical light guide plate (MOLGP), of which the top surface is designed as aspheric semi-cylindrical micro-concentrator structure (ASCMCS) arrays and the bottom surface is fused with micro-prism arrays coated with a high-reflective film. And we also present the optimized structural parameters and distribution pattern of the MOLGP. By the simulation of the professional optical software Lighttools, it’s verified that the integrated MOLGP we proposed can achieve the functions of five complex-structure films in current typical backlight module (BLM), and the Five Parameters (light energy utilization efficiency, average illuminance and luminance, uniformity of illuminance and uniformity of luminance) in the BLM with integrated MOLGP are respectively 1.49, 1.40, 1.07, 0.91 and 0.97 times than those in the typical BLM. Obviously, the performance parameters of the MOLGP exceed the traditional design. Moreover, we design two sets of four-step masks of the ASCMCS by the graphical user interface (GUI). At last, we fabricate a 1.8 inch integrated MOLGP sample. Comparative experiments show that the Five Parameters of the fabricated MOLGP sample are respectively 1.43, 1.43, 0.97, 0.89 and 0.70 times than those of the typical BLM. The experimental results verify the feasibility of the concept of the integrated MOLGP proposed in this paper.
