摘要	In this paper, we propose a technical route to prepare full-color display device based on blue Micro-LED array and environmental friendly InP/ZnS quantum dots. We design the new structure of full-color Micro-LED display device. We design and prepare InP/ZnS quantum dots color conversion layer which matches the blue Micro-LED array. In our new structure of full-color Micro-LED device, InP/ZnS quantum dots color conversion layer is inverted and has no direct touch with the blue Micro-LED array which can relieve the adverse effect on the PL characteristic of InP/ZnS quantum dots material. In order to prepare quantum dots layer with uniform film and uniform luminescence, flexible PDMS polymer layer is embedded into the substrate of the color conversion layer to eliminate coffee-ring effect. At the same time, the patterned 500 nm longwave filter film embedded into the substrate of the color conversion layer can suppress blue light emission which can improve the color purity of the InP/ZnS quantum dot pixel luminescence unit. Finally, a 1616 InP/ZnS quantum dots color conversion layer with a pixel pitch of 90 m was prepared experimentally. Based on the design and preparation method, the full-color Micro-LED device can be prepared with lower cost and higher efficiency. 2020, Science Press. All right reserved.
