TriLite and ams Osram Collaborate on Ultra-Compact AR Display Technology

TriLite has announced a partnership with ams Osram to integrate ams Osram’s RGB laser diodes into TriLite’s Trixel 3 laser beam scanner (LBS), known for its compact projection display. The Trixel 3 LBS offers low power consumption (below 320 mW) suitable for extended use and supports a broad color range that exceeds the standard sRGB. This technology is particularly suited for augmented reality (AR) solutions and applications such as smart glasses.

TriLite’s design is optimized for mass manufacturing, integrating customized standard components and advanced production equipment. This results in an optical display engine with a brightness of 15 lumens. The Trixel 3 system has a low latency, ensuring synchronization of AR visuals with the user’s environment. It’s also compatible with modern waveguides without needing additional optics, saving space and weight.

The Trixel 3 LBS integrates a 2D MEMS mirror and optical components. In projection technology, managing where and how the light is directed is of paramount importance and, in this case, the MEMs mirror rapidly moves to reflect a laser beam in precise directions, creating the pixel images we see in a projected display, while various lenses, filters, and other optical components are used to manipulate and direct light in the system. Traditionally, a lot of this control might be managed with hardware, but the trajectory control module (TCM) in Trixel 3 LBS allows for a different approach. It shifts many of the tasks related to controlling the path the light from hardware to software. By doing this, the complexity and potential bulkiness of the hardware are reduced, leading to a more compact and potentially more flexible system. Software-driven controls can allow for easier updates and adaptability as technology. So, the module’s specifications include a weight of less than 1.5 grams and a volume under 1 cm3.
