DAEGU, South Korea, April 6, 2020 — 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. According to the research team, the LEDs produced this way emit light in a more flexible, stable way than conventional LEDs.
