Physicists at Julius-Maximilians-Universität Würzburg have developed the world’s smallest light-emitting pixel, marking a breakthrough toward ultra-compact displays for smart glasses and other wearable devices.
Smart glasses, or eyewear that can project digital information directly into a user’s field of view, are often seen as a cornerstone of future wearable technology. Until now, however, progress has been limited by bulky components and optical constraints that prevent efficient light emission when pixels are reduced to the scale of a single wavelength.
