10,000 pixels per inch

Samsung and Stanford University have developed OLED technology that supports resolutions up to 10,000 pixels per inch – well above what you see in virtually any existing display, let alone what you'd find in a modern VR headset like the Oculus Quest 2.

The new OLED tech uses films to emit white light between reflective layers, one silver and another made of reflective metal with nano-sized corrugations.

This "optical metasurface" changes the reflective properties and allows specific colors to resonate through pixels. The design allows for much higher pixel densities than you see in the RGB OLEDs on phones, but doesn't hurt brightness to the degree you see with white OLEDs in some TVs.

This would be ideal for VR and AR, creating a virtually 'flawless' image where you can't see the screen door effect or even individual pixels. This might take years to arrive when it would require much more computing power, but OLED tech would no longer be an obstacle.
