Smallest OLED Pixels So Far
Scientists have successfully shrunk OLED pixels to the nanoscale, paving the way for a new generation of 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.
Physicists have solved this problem by creating the world's smallest working light pixel, demonstrating how future displays for smart glasses and other wearables can become smaller, yet remain bright and stable.
The team from Julius-Maximilians-Universität Würzburg in Germany achieved this by combining an organic light-emitting diode (OLED) with an optical antenna, designing a new structure that controls current spread and strengthens light output.
The research shows how future displays for smart glasses and other wearables can become much smaller while remaining bright and stable.
