19‐1: <i>Invited Paper:</i> Advancing Inkjet‐Printed Electroluminescent Quantum‐Dot Displays Toward Commercialization: Improving Blue EL‐QD Lifetime

One of the primary challenges in commercializing electroluminescent quantum dot (EL‐QD) displays is the limited operational lifetime of blue‐emitting devices. To address this, we explored various strategies focusing on optimization of both materials and inkjet printing processes. The efficiency and lifetime of blue EL‐QD devices are significantly improved through ligand engineering of ZnSeTe QDs and defect control in ZnMgO nanoparticles. We successfully demonstrate an allinkjet‐ printed 18.2‐inch full‐color EL‐QD display with a resolution of 202 ppi.
