May 27, 2022 – TriLitea developer of ultra-compact projection screens, announced this week that it was working with Dispelix, a supplier of transparent waveguides for wearable devices, 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 imaging system requires a projector, such as Trixel 3, along with a waveguide, which is a thin, mostly transparent piece of glass or plastic that bends and combines light beams from several sources in the eye.
TriLite claims its Trixel 3 projector is the smallest LBS projector in the world. With a volume of less than 1 cm3 and an ultra-light weight of 1.5g, the small module allows for comfortable long-term wear, according to the company. Trixel 3 also does not require additional relay optics between the LBS projector and the waveguide, which can typically double the size of systems using this setup.
TriLite noted that the system’s combined form factor with Dispelix’s ultra-thin waveguide will mean AR will be possible “in every pair of glasses, regardless of size or style.”
Peter Weigand, CEO of TriLite, said, “Dispelix’s optimized waveguides are the best in the industry, and our collaboration will result in some of the thinnest, lightest and best performing consumer AR devices around.” of the market.
Josh Littlefield, CRO at Dispelix, said, “Dispelix is delighted to be working with TriLite, as its Trixel 3 laser beam scanner is truly an engineering marvel. Trixel 3 deserves an equally innovative waveguide and we are proud that TriLite considers us their preferred waveguide partner.
In addition to the miniature size of the system, another benefit of the two companies working together is that TriLite’s high-luminosity LBS supports the large eyebox of Dispelix waveguides. This projection system can generate the high brightness required even for extreme outdoor use, for example, alpine ski goggles. The large eyebox eliminates the need for custom fitting and adjustment of AR smart glasses, ensuring a true and sharp image no matter who is wearing the glasses, according to the company.
