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.
To transmit energy to their light-emitting layer, existing LEDs use a coplanar structure that surrounds the light-emitting layer. This structure requires mechanically compliant electrodes with high transmittance, durability, and stable electrical conductivity. The light emitted from the light-emitting layer can get blocked by the…READ MORE
