A 10,000 PPI screen from Samsung and Stanford may be perfect for VR

Researchers from Samsung and Stanford have come up with a variation of organic light-emitting diode (OLED) technology that packs way more pixels per inch than any current display—10,000 or more, compared to hundreds of pixels per inch as found on even the most expensive smartphones. What’s especially exciting about the technology is that it would be ideal for next-gen VR headsets.

Even the best VR headsets exhibit what is known as the screen door effect, whereby a viewer can make out the lines between pixels, like looking outside through a screen door. This happens because headsets essentially jam the display lenses just inches away from a viewer’s eyeballs. And the best way to combat it is by cramming more pixels into the lenses.
