Collaboration enables RGB laser diodes in ultra-compact AR smart glasses display module

11-09-2023 | TriLite | Semiconductors

TriLite has announced its technology collaboration with ams OSRAM. ams OSRAM will supply its sub-assembled RGB laser diodes to 'light up' TriLite's Trixel three laser beam scanner (LBS), the world's smallest projection display.

The LBS supplies ground-breaking compactness and lightweight as a bright and accurate display. It offers ultra-low power consumption (<320mW) for all-day use and full-colour support (>200% over sRGB) for excellent image quality. Trixel 3 enables AR solutions for smart glasses and various consumer applications.

Dr Peter Weigand, CEO at TriLite, expressed his excitement about the collaboration: "Our ecosystem strategy focuses on partnering with world leaders to ensure top quality and reliable mass manufacturing. We chose ams OSRAM as one of our technology partners due to its laser light sources' class-leading power and efficiency, which perfectly align with the brightness, contrast, and high-performance requirements of our Trixel 3 LBS projector."

Dr Jörg Strauss, senior vice president and general manager of Business Line Visualisation and Sensing at ams OSRAM, commented: "We are excited to partner with TriLite as Trixel 3's compact design paves the way for widespread adoption of 'always-on' consumer AR glasses. We are proud that ams OSRAM's laser diodes offer the key specifications essential for achieving the small form factor of Trixel 3."

The ultra-compact optical display engine has a brightness of 15 lumens, providing effortless readability even in direct sunlight. Its low system latency lets AR images blend naturally with the wearer's surroundings and movements, providing an immersive AR experience that exceeds consumer expectations. Furthermore, Trixel 3 is totally compatible with state-of-the-art waveguides without needing relay optics, effectively saving space and lowering weight.

The ultra-compact and lightweight LBS optical display engine combines a single 2D MEMS mirror, all optical components, and the unique Trajectory Control Module that shifts light module complexity from hardware to the software domain. The LBS module weighs less than 1.5g and has a less than 1cm3 volume.
