Micro-light-emitting diode (MicroLED) display technology has drawn a lot of attention in display industry recently owing to the superior optical and electrical properties. Compared to conventional display technologies, MicroLED display demonstrates higher efficiencies, longer lifetime, much higher brightness, ultra-high pixel density, faster response time and wider color gamut. MicroLED display is an emerging technology which can be used for all current display applications and new scenarios, such as transparent, seamless tiling, and AR glasses for metaverse. Based on our proprietary PixeLED display, SMAR·Tech, PixeLED Matrix, and µ-PixeLED technologies, we could utilize different process for each application with MicroLED displays.
