Abstract：The widespread application and popularization of novel display products such as wearable devices, augmented reality(AR), and mixed reality(MR) have imposed higher performance requirements on new display technologies,particularly in terms of miniaturization, high resolution, and high stability. Micro-display devices based on microlight emitting diodes(MicroLEDs) exhibit outstanding characteristics including low power consumption, high stability, long lifespan, and fast response time. In recent years, related technologies and products have been widely applied in VR/AR glasses and micro-projection devices. By integrating color conversion pixels and metasurface structures on blue MicroLED matrix pixel chips, red, green, and blue(RGB) tri-color array light-emitting devices can be constructed, enabling dynamic full-color image display under active drive control. This paper summarizes the mainstream technologies for achieving full-color micro-display with MicroLEDs, including phosphor color conversion technology, quantum dot color conversion technology, and metasurface integration technology. It further analyzes and compares the advantages and disadvantages of these technologies, reviews the latest research progress in MicroLED full-color micro-display devices, and discusses the significance of these technologies in promoting the development of the new display industry.
