Display technology that uses light-emitting diodes is extensively used in devices such as televisions, computers, and mobile phones. Compared to traditional liquid crystal displays and organic light-emitting diode screens, the micro-light-emitting diode (Micro-LED) displays offer notable benefits in size, performance, power efficiency, and lifespan. We provide an overview of the technology types and application scenarios of full-color Micro-LED displays, describe the latest research in creating full-color displays using Micro-LED, including massive transfer technology, color conversion layer integration technology, and epitaxial chip monolithic integration technology. Furthermore, we compare the strengths and weaknesses of these technologies and look ahead the future evolution of Micro-LED-based full-color display technology.
