Abstract

As of today, display performance is a major development criteria in the quest to deliver consumer-ready, high-quality XR glasses. Laser beam scanners in comparison with other display technologies are among the most promising high-dynamic range RGB display engine architectures, e.g., because the size of these devices remains unchanged when increasing the display resolution and field of view. This is in sharp contrast to competing display engines where each pixel constitutes an individual component and these technologies at some point seem to reach their physical limits. On the other hand, manufacturing state-of-the-art laser beam scanners including optics seems especially labor intensive, exhibiting a low yield, therefore driving up the price of XR glasses. This paper addresses the potential benefits and pitfalls of using laser beam scanners in XR and gives an insight into new solutions in next-gen laser beam scanning devices like, e.g., replacing cumbersome hardware beam combination by mere software solutions.
