摘要	In traditional LED display screen, optical energy utilization rate and imaging filling ratio are very low. Based on the theory of non-imaging optics, a structure system and a design method are developed to improve optical energy utilization rate and imaging filling ratio of full-color LED display. Using compound parabolic concentrator (CPC), light diverging angle emitted from LED chips is transformed and compressed. Therefore, total reflection loss on external surface of display module can be avoided. Accordingly, optical energy utilization rate of display system is greatly improved. Based on uniform lighting principle of integrator-rod and light distribution principle of scattering, imaging filling ratio, pixel uniformity and primary color multiplexing area of LED display screen are improved. According to the above method, a P10 mm full-color LED display module is designed. Using LIGHTTOOLS software, the display module system is simulated and analyzed. The simulation results show that, optical energy utilization rate of system is higher than 70%, imaging filling ratio closes to 100%, uniformity of unit pixel area is better than 85%. The display module has the advantages of high energy utilization rate, high imaging filling ratio, uniform and soft showing, easy manufacturability.
