AC Power: A Game Changer for NanoLEDs
Conventional LEDs use DC power, requiring two contacts, which poses a complicated alignment problem for device manufacturers as device form factors shrink.
Researchers at Nanjing University have described using AC power to drive an LED device in Applied Physics Letters, significantly reducing fabrication complexity for nanoscale LED devices.
“Using AC was absolutely essential for our design,” said author Tao Tao. “It allowed us to explore a new regime of LED behaviour.”
This innovation could be a game-changer for sharper near-eye displays, simplifying design with AC power and only one contact, and improving fabrication and device performance.
