Abstract
Liquid dispersions of quantum dot particles comprise an acrylic medium and quantum dot particles dispersed in the acrylic medium have an initial viscosity. The quantum particles comprise ligands attached to the quantum dot particles, the ligands comprising functional groups configured to stabilize the initial viscosity liquid dispersion of the quantum dot particles. The liquid dispersions of quantum dot particles are useful as stable liquid formulations that resist gelling for spin-coating and inkjet printing of color conversion layers in the manufacture of LED and micro-LED panel for advanced displays. Methods of manufacturing light-emitting devices using the liquid dispersions of quantum dot particles are disclosed.
