20‐5: Quantum Dots and Device Optimizations towards Ink Jet Printing Quantum Dots Light Emitting Diodes Displays

In this paper, we have meticulously refined both the quantum dot (QD) materials, particularly the blue variants, and the ink formulations to achieve aesthetically pleasing, high‐performance printing devices. Furthermore, in anticipation of future mass production challenges, we have tailored the quantum dot ligands and adopted surface passivation of zinc oxide nanoparticles, leveraging their inherent material properties. This innovation has culminated in remarkable enhancements for inkjet QLED device in long‐term storage stability and efficiency.
