XR(AR/VR/MR) devices are becoming the major players in this upcoming industrial revolution as they are the main user interface(UI) devices connecting human and artificial intelligence(AI). To overcome two big huddles of XR devices, ultra-small display and optic, RAONTECH implemented two state-of-the-art technologies to design thumbnail-sized display, microdisplay. Our semiconductor technology trusted by world’s top tier customers has been combined with display technology to develop the world’s first quad-HD microdisplay, optic-aware image processing controller SoC, and reference optic lens, all with the lowest power for AR smart glasses and HMD (Head Mounted Display).
