Micro-OLED displays with 1080p (1920x1080) resolution have been around for a few years now, but a group of German researchers has taken things to the next level. They've engineered an OLED pixel so small that an entire 1080p display could fit into a single square millimeter, potentially changing the game for wearable displays.

We're talking about an OLED tiny enough that the wavelength of the light it emits is larger than the pixel producing it. In this case, it's a subwavelength pixel measuring just 300 by 300 nanometers that can produce orange light, according to a paper published in Science Advances by physicists from the University of Würzburg.

And yes, for those wondering, this pushes the limits of classical optics, the university pointed out in its summary of the research, led by p
