System is described in US Patent 10778962.
The claims are actually written pretty well. It's like looking through a bunch of magnifying glasses at an LCD. Depending on what angle and distance you look through the magnifying glass from, you see a magnified image of one specific area (a diffuser is employed so you don't end up peeping the sub-pixels, which is also why the color depth is very limited). With detailed tracking of your location, the software can switch the pixels underneath the magnifying glasses you're looking through to produce a coherent image at a subsampled resolution.

- bri3d 4y agoThe patent mentions this system a few times, and it sounds like they moved away from this model due to mainly cost/benefit and scale up reasons. Laser pico projectors are certainly an easy way to do this, they're literally just a laser aimed using a mirror and you can steer a beam exactly where you want it. I'm surprised they're not hacked on more as they're probably one of the coolest gadgets around technology wise.
