Abstract

Micro light-emitting diodes (micro-LEDs) are considered crucial for the next-generation display technology. However, the high cost of large-scale transfer technology and the lack of maturity in full-color technology have hindered the availability of mature products. The perovskite quantum dot (PQD) material offers a promising solution for achieving full-color capabilities in micro-LED displays. This review article aims to provide an overview on the latest progresses on PQD full-color technology for micro-LEDs. The review covers a variety of patterning techniques, including photolithography, inkjet printing, microfluidic processing, and laser processing, as well as the research on intrinsic stability of PQDs. Finally, the current drawbacks and solutions of PQD color conversion micro-LEDs are discussed, and the future research prospects in this field are anticipated.
