Samsung and Stanford invent a 10,000 PPI display
Samsung researchers, along with colleagues from Stanford University, have developed a new type of OLED screen with a pixel density of 10,000 PPI. It uses a clever trick called light resonance - the concept is the same as sound resonance - for example when a guitar body resonates with the strings to produce sound. In this case, the light resonates on a nanoscale level between two very special surfaces to produce different colors out of a white light OLED source. As lightwaves of different colors are quite tiny, using this method the researchers can effectively produce really tiny color “pixels”.
Of course, the prototype is still in the lab and probably won’t leave to enter mass-production anytime soon. When it happens though, it might revolutionize the OLED display industry, leading to immersive VR tech, crazy high pixel count TVs, and smartphone display.
