Now, Samsung and Stanford researchers have created an OLED display with a pixel density of roughly 10,000 PPI (h/t: IEEE Spectrum).

The researchers used an OLED film to beam out white light to two reflective layers, with one being a silver film and the other being a “metasurface.” This metasurface features a “forest of microscopic pillars,” which serve as pixels measuring 2.4 microns in size.

The team notes that light is reflected back and forth between these layers, with this build-up enabling “twice the luminescence efficiency of standard color-filtered white OLED displays, as well as higher color purity.” Check out an image showing the screen tech below.
