TriLite has announced that form factor engineering samples for its Trixel® 3 laser beam scanner (LBS) are now available, combining the display engine, control electronics and its unique Trajectory Control Module (TCM) software. By providing all the system-level components required for evaluation, application development and test, these samples will enable customers to rapidly prototype their augmented reality (AR) systems and cut time-to-market.

Claiming to be the world’s smallest projection display, the Trixel 3 provides ground-breaking compactness and light weight, coupled with exceptional brightness and accuracy. It enables AR user cases for smart glasses and a wide range of consumer applications, with ultra-low power consumption (<320 mW) for all-day use.

The engineering samples are based around the Trixel 3 optical display engine, which combines a single 2D MEMS mirror, RGB laser diodes and all optical components. The LBS unit is supplied pre-calibrated for color alignment and distortion correction. The display engine and the driving electronics are now form factor, which is important for customers to rapidly design and prototype their AR systems leveraging Trixel 3 technology.

Dr. Dietmar Gleispach, COO at TriLite, said, “With these engineering samples now available, we are very close to the final specification of Trixel 3. This represents a key milestone for having a qualified product on a qualified production line according to TriLite’s APQP and enabling ramp up later this year with lead customers.”

The latest TCM software is supplied with the engineering samples. TCM is part of TriLite’s ‘software-defined display’ approach, which shifts complexity from the hardware to the software domain. It uses proprietary algorithms to ensure optimum image quality and minimum latency, control position and brightness at subpixel accuracy, and to assure low power consumption. TCM runs on a host processor, and the engineering samples include a suitable evaluation host.

The engineering samples also include driving electronics for connecting the Trixel 3 LBS to the host. This includes the TriLite Image Controller (TIC), and drivers for the RGB laser diodes and the MEMS mirror.

With a rapidly expanding ecosystem of manufacturing partners, TriLite designs for seamless mass production, incorporating customized standard components and utilizing state-of-the-art high-volume production equipment. The result is an ultra-compact optical display engine with a brightness of 15 lumens, ensuring effortless readability even in direct sunlight. Its low system latency allows AR images to blend naturally with the wearer’s surroundings and movements, providing an immersive AR experience that exceeds consumer expectations. Trixel 3 is fully compatible with state-of-the-art waveguides without requiring any relay optics, thus saving space and reducing weight.
