When we talk about pixel density, there is the argument that when it comes to smartphones, it stops being as relevant at a certain point or resolution. This is because at the distance we typically hold our phones, our eyes stop noticing how sharp certain things are, like the difference between a 720p display on a 5-inch smartphone and a 1080p display on a 5-inch smartphone.
However, that’s a very different thing when it comes to tech like virtual reality or augmented reality, where the displays are quite literally in your face and that’s when you start to notice the difference, but that’s something that Samsung and researchers at Stanford University are hoping to change with the development of a 10,000 DPI display.
This display was created using films to emit white light between reflective layers, with one made of silver and the other made using a reflective metal with nano-sized corrugations. The reflective properties allow for specific colors to resonate through pixels, which in turn allows for higher pixel densities that you would normally get in smartphones or TVs.
By creating a display with such high pixel density, it would allow companies to create displays for use in VR or AR that some might call “flawless”, and remove or reduce the “screen door” effect where you can actually see the gap between pixels when they’re placed so close to your eyes.
