Balacing Charge Extends QD Efficiencies
Chinese researchers have taken quantum dot (QD) LEDs above 20% external quantum efficiency (EQE) – thought to be the technology’s theoretical maximum (Display Monitor Vol 20 No 20) – for the first time. By adding an insulator layer to the design structure, a team at Zhejiang University achieved an EQE of 20.5%, with an operational … Read more
