TriLite and Dispelix partner on ultra-compact projection display for AR glasses

TriLite, developer of the world’s smallest projection display, announces that it is working with Dispelix, the leader in see-through waveguides for wearables, to create an ultra-compact display system for Augmented Reality (AR) smart glasses. The system combines TriLite’s Trixel 3® laser beam scanner (LBS) with Dispelix’s advanced waveguides.


For AR glasses, the image creation system requires a projector, such as Trixel 3, as well as a waveguide, which is a predominately-transparent, thin piece of glass or plastic that bends and combines light beams from multiple sources into the eye.


Trixel 3 is the world’s smallest LBS projector. With a volume of less than 1cm3 and ultra-light weight of 1.5g, the tiny module enables comfortable long-term wear. It does not require any additional relay optics between the LBS projector and the waveguide, which typically doubles the size of systems that use competitor products.


The combined system form factor with Dispelix’s ultra-thin waveguide is one of the most compact ever achieved – meaning that AR will be possible in every pair of glasses, regardless of size or style.


Peter Weigand, CEO at TriLite, said: “Dispelix’s optimized waveguides are the best in the industry, and our collaboration will result in some of the thinnest, lightest and highest-performing AR consumer devices on the market.”


Josh Littlefield, CRO at Dispelix, said, “Dispelix is excited to be working with TriLite, as its Trixel® 3 laser beam scanner is truly a marvel of engineering. Trixel® 3 deserves an equally innovative waveguide and we are proud that TriLite sees us as their preferred waveguide partner.”


In addition to the system’s miniature size, another benefit of the two company’s collaboration is that TriLite’s high brightness LBS supports the large eyebox of Dispelix waveguides. This projection system can generate the high brightness required even for extreme outdoor usage, for example, alpine skiing glasses. The large eyebox eliminates the need for custom adjustment and fitting of AR smart glasses, ensuring a true, crisp image is achieved regardless of who is wearing the glasses.
