Here’s a new display technology that I hadn’t heard of before…
A new OLED display from Samsung and Stanford can achieve more than 10,000 pixels per inch, which might lead to advanced virtual reality and augmented reality displays, researchers say.
The new display uses OLED films to emit white light between two reflective layers, one of which is made of a silver film, whereas the other is a “metasurface,” or forest of microscopic pillars each spaced less than a wavelength of light apart.
