Researchers create 10,000 ppi OLED screens, which could be great for VR

  • Samsung and Stanford researchers have created 10,000 ppi OELD screens.
  • This offers even more pixel density than a 6-inch display with 32K resolution.

Pixel density is a major factor in screen quality, serving as a measure of how sharp the display is. The Sony Xperia 1 II and its 4K screen deliver 643 pixels per square inch (ppi), the sharpest screen on smartphones in 2020.

Now, Samsung and Stanford researchers have created an OLED display with a pixel density of about 10,000 ppi (h / t :). IEEE spectrum). In other words, even a 6-inch display with 32K resolution (30,720 x 17,280) does not match, topping out at around 6,000 ppi.

The researchers used OLED film to create two reflective layers of white light, one with a silver film and the other with a “metasurface”. This metasurface contains a “forest of microscopic pillars”, acting as pixels measuring 2.4 microns in size.

The team notes that light is reflected back and forth between these layers, giving the build-up “standard color-filtered white OLED displays, as well as double luminescence efficiency of high color purity.” Check out an image showing the screen tech below.

VR could be a perfect use-case for this I 10,000 PPI performance, according to researchers. It certainly sounds like a funny use for that technology, and it would be a fatal leap on existing consumer headsets. For example, the Valve Index and HTC Vive Vive Cosmos offer a PPI of less than 800 years.

It is also worth noting that a 10,000 ppi screen will require a ton of horsepower for VR and general computing that is not yet available to consumers. For example, the latest and greatest RTX 3090 graphics card on 8K is on top. This translates to 275 ppi for a 32 inch 8K monitor.

We immediately put 10 thousand ppi on smartphones. Don’t bank by looking at the OLED display. In addition to the horsepower requirements, all those pixels drain a large amount of battery.

However, research by Samsung and the Stanford team notes that 20,000 ppi is really the theoretical limit for technology. However, they note that when you shrink these pixels below one micron in size, the brightness is a commercial off.
