Abstract

Quantum dot light-emitting diodes (QD-LEDs) have attracted considerable interest for their wide-range of color tunability, high brightness, and good color purity due to their quantum confinement effect. However, challenges remain in achieving the necessary multilayer device structures using printing processes for display applications. Many printing technologies need to be employed to build multi-stacking patterns and devices. For the first time, QD emitting layers were printed by electrohydrodynamic (EHD) jet spray technology and applied to all solution-processed QD-LEDs except for the electrodes. The QD-LEDs have a structure of ITO/PEDOT:PSS/PVK/EHD-sprayed QDs/ZnO/Al. The sprayed QD patterns were controlled with various parameters to obtain uniform surface morphology. The optimized QD-LED device showed a luminance of 5154 cd/m2 and a current density of 2.18 cd/A, and EQE of 1.47%.
