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.
