Are we anywhere close to getting that resolution at that density? I think it would require a similar form factor to what you said, but lower resolutions are probably workable. The biggest thing would likely be privacy issues, just like with Glass.
MicroLEDs will fuel the next display revolution and are smaller than some bacteria. They can eventually achieve the perfect pixel density for AR/VR while having better display characteristics than even OLEDs.
Hmm, I was hearing 5k ppi with microLED. 8k displays and cameras for a set of glasses would probably be plenty.
You need 16K per eye to beat human visual density.
But do you actually need to beat human visual density to make a widely adopted product? I'm not convinced that screen resolution is the factor holder back adoption, even at the current densities.
