Light-engine and imaging optics jointly determine the performance of augmented-reality (AR) and virtual-reality (VR) displays in terms such as power consumption, form factor, field-of-view, eye box, image quality, contrast ratio, cost, etc. In immersive VR headsets, high-dynamic-range miniLED backlit LCDs and organic light-emitting diode (OLED) displays are currently the two dominant technologies, while high-efficiency pancake lenses and beam-shaping films help to reduce the form factor and power consumption. In optical see-through AR displays, high brightness yet ultracompact liquid-crystal-on-silicon, OLED-on-silicon, microLED displays, MEMS, and laser beam scanners are strong contenders to offer a high ambient contrast ratio for outdoor applications. In terms of optical combiner, geometric optics, diffractive waveguide, achromatic waveguide, and metalens visor are promising candidates for expanding the eye box while keeping a compact and lightweight form factor.
