Micro-LED array for full-color micro-LED display and ultrafast optical communication

Micro-LEDs have demonstrated attractive applications including potentially next-generation display and 6G optical communication, due to their special characteristics of small size, localized light emission, and high heat dissipation ability. But challenges still exist in achieving full-color micro-LED display and high-speed optical communication. Recently, we have successfully realized novel full-color micro-LED display based on a single-chip utilizing multi-wavelength multi-quantum wells (MQWs), and stacked blue and yellow micro-LED arrays. High-bandwidth GaN-based micro-LED arrays of ~2GHz were also developed for applications in visible light communication of ~10Gbps.
