World’s smallest OLED pixel could transform smart glasses Date: March 4, 2026 Source: University of Würzburg Summary: Researchers have built the smallest OLED pixel ever made—just 300 nanometers across—without sacrificing brightness. By redesigning the pixel with a nano-sized optical antenna and a protective insulation layer, they prevented the short circuits that normally plague devices at this scale. The result is a stable, ultra-tiny light source that could allow full HD displays to fit on an area the size of a grain of sand.

Hopefully it does not suffer from the 'burn in' effect :-)
