Abstract

Laser Beam Scanning microdisplays (LBS) offer the advantages of high brightness with millions of nits, high efficiency, high contrast, ultra compact size and high resolution. That makes this display technology attractive for smooth integration into stylish all-day wearable AR smartglasses. In combination with diffractive waveguides or other combiners this technology enables to realize AR smartglasses with large eyebox and high contrast even at bright daylight. Besides presenting an ultra-compact full-color display light engine that includes RGB laser, optics, 2D MEMS mirror and ASICs we will also report on scalability of resolution, field of view, brightness and other characteristic advantages of this display technology.
