Samsung Electronics and Stanford University announced that their collaboration has resulted in an impressive 10,000 pixels per inch (PPI) OLED display. Such screens are planned to be used in virtual reality devices, in which the display is very close to the user’s eyes.
Such displays are vastly superior to those used in virtual reality glasses today. It should be added that the screens of most flagship smartphones today have a density of 400-500 pixels per inch.
Samsung’s OLED screen uses films to emit white light between reflective layers. This allowed for a much higher pixel density than traditional OLED screens on phones.
In laboratory tests, the researchers claim that the tiny pixels they create provide higher color purity and 2x the luminescence efficiency of color-filtered white OLEDs.
