The information display device is not only capable to deliver the content on the plane of the display screen， but more importantly， to display the content in a real three-dimensional space， making the natural interaction between individuals and information possible. Micro-LED displays have received much attention because they have the potential to bring us into a new era of truly immersive and interactive experience. Fast response time， micro size， wide environment temperature， and long operating lifetime， enable Micro-LED display for almost all display application， even flexible and transparent display. By reducing the diameter of LEDs， they show great promise in very high pixel density display. It is believed that Micro-LEDs could pave the way for realizing highly integrated semiconductor information display （HISID）， embracing the next generation information display technology.
