Researchers are pushing LED technology into the nanoscale realm, with recent demonstrations of LEDs as small as 90-100 nanometers. While traditional microLEDs use III-V semiconductors like gallium nitride, these breakthrough nanoLEDs employ alternative materials including organic semiconductors (OLEDs) and perovskites. The tiny LEDs achieve pixel densities up to 100,000 pixels per inch but suffer from reduced efficiency (5-13% vs 50-70% for conventional LEDs). Potential applications include ultra-high-resolution VR displays, on-chip photonics for data centers, and exotic uses like metasurfaces for beam control and holographic displays.
