Abstract
The present invention provides a perovskite microsphere material, a mixed-color light conversion film, preparation methods thereof, and a display. By using the red and green perovskite microspheres with the encapsulating structure provided by the present invention as an optical conversion material of the white OLED display, the photon utilization of organic light-emitting materials can be improved, display power consumption is reduced, and thus process difficulty and cost are decreased.
