Recent Advances in Nitride-Based Micro-LEDs for Next-Generation Display

Nitride-based Micro-light-emitting diode (Micro-LED) is now spreading into the field of display technology, which has been dominated by liquid crystal display (LCD), and organic LED (OLED). While high-power LEDs for solid-state lighting have been matured for many years, Micro-LEDs present significant challenges in manufacturing and characterization. This paper explores recent developments in Micro-LED display, providing an overview of current technologies and future possibilities in this field. This review focuses on the key technologies involved in manufacturing Micro-LEDs, including epitaxy and chip processing, mass transfer, driving, bonding, and detection technologies. It further summarizes the emerging applications of Micro-LEDs in full-color displays, flexible displays, augmented reality (AR), and virtual reality displays (VR).
