Smallest OLED Pixels So Far
Scientists have successfully shrunk OLED pixels to the nanoscale, paving the way for a new phase in wearable displays.
A major challenge in shrinking display LEDs has been overcome, as small LEDs often fail due to current concentration at their corners, causing short circuits.
Their research shows how future displays for smart glasses and other wearables can become much smaller while remaining bright and stable.
The team from Julius-Maximilians-Universität Würzburg in Germany built the new pixel using an organic light-emitting diode (OLED) combined with an optical antenna, designing a new structure that controls current spread and strengthens light output.
