That display type can be made bright enough to be outdoor visible while still keeping power consumption on sane levels.

The biggest problem of all waveguide systems is that they are freaking inefficient, with optics consuming 50-90%+ of all light.

And it is the same problem with pretty much all complex optical systems in AR/VR glasses.

This is why I am a proponent of using mirror optics in this application.
