High resolution density, wide field of view (FoV), lightweight and compact formfactor, and low power consumption are demanding requirements for augmented reality (AR) and virtual reality (VR) displays. Compared to liquid crystal displays (LCDs) and organic light-emitting diode (OLED) displays, microLED is attracting more attention due to its high peak brightness, excellent dark state, high resolution density, small formfactor, and long lifetime.
