As part of its latest endeavor, Samsung teamed up with researchers from Stanford to yield an ultra-high-resolution OLED display with 10,000PPI.
Much to the delight and relief of VR fans, the screen door effect, or the gaps between pixels that are visible when looking at a display so close to their eyes, might disappear entirely if Samsung and Stanford University’s plan works out. They have developed (via IEEE Spectrum) an OLED technology that supports resolutions up to 10,000 pixels per inch.
This is considerably above what we see in virtually any existing display, let alone what you are likely to find in a modern VR headset such as the Oculus Quest 2. The newOLED tech adopts films to emit white lights between reflective layers – one silver and another made of reflective metal with nano-sized corrugations.
This optical metasurface modifies the reflective properties, allowing specific colors to reflect through pixels. Furthermore, the design paves the way for higher pixel densities than what you see in the RGB OLEDs on phones but doesn’t hurt brightness to the extent you see with white OLEDs in some televisions.
This would be perfect for VR and AR, considering that it creates a virtually ‘flawless’ image where the screen door effect or even the individual pixels aren’t visible. This might not arrive any time soon and would require much more computing power, but OLED tech would no longer be a stumbling block.
Interestingly, it is more practical than you might think. The North Korean tech giant is already working on a full-size display using the 10,000PPI tech, and the design of the corrugations make large-scale manufacturing feasible. It may be just a question of where and when you see this OLED rather than “if.”
