When we talk about pixel density, there is the argument that smartphones are no longer as relevant after a certain point or resolution. This is because at the distance we normally hold our phones, our eyes no longer notice how sharp certain things are, like the difference between a 720p display on a 5 inch smartphone and a 1080p display a 5-inch smartphone.
However, this is an entirely different matter when it comes to technologies like virtual reality or augmented reality where the displays are literally in the face and you can tell the difference, but that's what Samsung and researchers at Stanford University are hoping for with the development of a 10,000 DPI -Change displays.
This display was created using film to emit white light between reflective layers, one made from silver and the other made from a reflective metal with nano-sized waves. The reflective properties allow certain colors to vibrate through pixels, which in turn enables higher pixel densities that you would normally get in smartphones or televisions.
By creating an ad with this high density of pixels, businesses can create displays for use in VR or AR that some consider "flawless" and remove or narrow the "screen door" effect where you actually leave the gap between the Seeing pixels when they are placed that close to your eyes.
