Abstract
Highly stabilized polymer-based quantum dot ink for super-fine inkjet printing technology is demonstrated. With ligand post-treatment for as-prepared QD ink, QD agglomeration at nozzle during printing is solved, which also shows better film morphology. Meanwhile, green and red monochromatic QD color conversion layer for microLED backlight is demonstrated, with 7um pixel size and 28.5%/17.8% LCE for each color, respectively.
