(Image credit: Getty Images/SENEZ) Researchers at the Julius-Maximilians-Universität Würzburg, Germany, have developed a new form of an organic LED that is many times smaller than existing options – measuring just 300 x 300 nanometers, according to SciTechDaily . If scaled up and built into a standard display, it would enable a 1080p screen that measured just 1mm across.
In the quest for lighter, more detailed, and brighter displays for augmented reality headsets and smart glasses, the most compact individual light-emitting diodes available as of 2025 are micro OLEDs. These measure just under five by five micrometers each, which is absolutely tiny compared to even the mini-LEDs that power many modern high-end TVs . But the new nanometer-scale OLEDs out of this German university and more than 10 times smaller.
“With the help of a metallic contact that allows current injection into an organic light-emitting diode while simultaneously amplifying and emitting the generated light, we have created a pixel for orange light on an area measuring just 300 by 300 nanometers. This pixel is just as bright as a conventional OLED pixel with normal dimensions of 5 by 5 micrometers,” says Bert Hecht, in the study published in Science Advances .
