Swiss researchers create world’s tiniest light-emitting diodes

Researchers at the federal technology institute ETH Zurich have produced what they claim to be the world's smallest light-emitting diodes. The tiny diodes will enable ultra-sharp screens and microscopes, but also opens up entirely novel possibilities for wave optics applications. +Get the most important news from Switzerland in your inbox The researchers have developed extremely small organic light-emitting diodes, so-called nano-OLEDs. These are so tiny that 100 can fit next to each other in the diameter of a human cell, ETH Zurich announced on Monday. Today, OLEDs are mainly used in high-quality smartphones and television screens. However, according to ETH Zurich, the newly developed nano-OLEDs are up to 50 times smaller than previous OLED pixels. This means that pixels can be arranged much more densely than with the previous technology. Pixels in the size range of 100 to 200 nanometres lay the foundation for ultra-high-resolution screens, which could display razor-sharp images ... Full story here Are you the author?
