The Lumus Maximus prototype has impressive overall image quality, including the field of view (FOV), resolution, color uniformity, and brightness, in a glasses-like form factor. As a prototype, there are issues that Lumus knows about and are planned to be fixed in the final product. The Maximus prototype only has the displays in the glasses with no batteries, processing, cameras, and SLAM. External cables drive the glasses with video and power. The Lumus Maximus uses a Compound Photonics (CP) 2048 x 2048 pixel LCOS micro display. It has high contrast with great color, small (3-micron pixels) for a small device and display engine, high reflectivity for good efficiency.
On top of all these capabilities, it supports a very high field sequence rate to prevent colors from breaking up with head motion. Lumus points out that the 50-degree diagonal FOV with a square aspect ratio is just the starting point for their 2D expanders. They can scale the waveguide both up and down to support other aspect ratios and FOVs. The image is particularly large in the vertical direction for a thin waveguide-based display with a square (1:1) aspect ratio rather than the more common 16:9 HDTV-like or 3:2 of Hololens. The Maximus’s display engine appears to be about 1/4th the volume of the Hololens 2 despite being much higher resolution and about 6 times the brightness.
