Story summary

Julius-Maximilian University in Würzburg researchers have developed a 300-by-300-nanometer pixel using optical antennas to enable compact displays for smart glasses.
The orange-emitting pixel matches the brightness of a conventional 5-by-5 micrometer organic light-emitting diode (OLED) pixel.
The work, published in Science Advances, addresses miniaturization by preventing uneven current distribution to ensure stable operation.
Future plans aim to improve efficiency and expand the color range for wearables such as eyeglasses.
