Perovskite as color conversion materials for micro-LED display

Metal halide perovskite materials have attracted great attention owing to their fascinating optoelectronic characteristics and low-cost fabrication via facile solution processing. One of the potential applications of these materials is to employ them as color-conversion layers (CCLs) for visible blue light to achieve micro-LED full-color displays. However, obtaining thick perovskite films and fine patterns to realize complete color conversion and vivid display performance is still very challenging. Here, we elaborately addressed above issues and successfully demonstrated efficient blue-to-green photoconversion based on perovskite materials and applied in full color micro-LED displays.
