World's Tiniest LED Display Has Pixels Smaller Than a Virus

Scientists at Zhejiang University have created the world's smallest LED display, featuring pixels just 90 nanometers wide -- roughly the size of a typical virus and too tiny to be seen with optical microscopes. The breakthrough, described in Nature this week, uses perovskite semiconductors that maintain brightness even at microscopic scales, giving them an advantage over conventional LEDs.The research team, led by Baodan Zhao, also demonstrated a larger display with pixels measuring about 100 micrometers (human hair width) that successfully rendered images including a spinning globe.
