Scientists have successfully shrunk OLED pixels to the nanoscale, paving the way for a new generation of wearable displays.
Previously, shrinking display LEDs was challenging due to the tendency of small LEDs to fail when current concentrates at their corners, causing short circuits.
Physicists have now overcome this issue by creating the world's smallest working light pixel, demonstrating how future displays for smart glasses and other wearables can become smaller, brighter, and more stable.
The team from Julius-Maximilians-Universität Würzburg in Germany achieved this breakthrough by combining an organic light-emitting diode (OLED) with an optical antenna, designing a new structure that controls current spread and strengthens light output.
Their research shows how future displays for smart glasses and other wearables can become much smaller while remaining bright and stable.
