28‐2: Distinguished Paper: Optimization of Ink Formulation and Ligand Engineering for QD‐LED Displays with Improved Performance

The efficiency and lifetime of inkjet‐printed QD‐LED displays are improved through the ligand exchange of Cd‐free QDs and optimal control of ink formulation. Dual ligands enhance colloidal stability and carrier transport properties. The introduction of appropriate additives in the mixed solvent syst...

description The efficiency and lifetime of inkjet‐printed QD‐LED displays are improved through the ligand exchange of Cd‐free QDs and optimal control of ink formulation. Dual ligands enhance colloidal stability and carrier transport properties. The introduction of appropriate additives in the mixed solvent system improves the inkjet processibility and the morphology of inkjet printed layers.
