A Full HD panel could fit into one square millimeter
Forward-looking: A team of physicists from Julius-Maximilians-Universität Würzburg in Germany have created the world's smallest pixel to date. Measuring just 300 by 300 nanometers, the tiny light source is just as bright as a conventional OLED pixel that's five by five micrometers in size and could eventually serve as the building blocking for next-generation, high-resolution wearable displays.
