In-Plane Electroluminescent Technology Could Improve LEDs for Displays and Wearables

Luminescence technology developed at Daegu Gyeongbuk Institute of Science and Technology (DGIST), using an in-plane electric field generated in parallel to the light-emitting layer of an LED, could help improve the efficiency of light-emitting elements used in billboards and banners. The device demonstrated strong electroluminescent (EL) intensities in a thick emitting layer — a parameter on which EL and mechanoluminescent (ML) intensities in coplanar structures are dependent.
