Abstract
Provided are methods for preparing optical ink, methods for preparing a monodisperse solution of zirconium dioxide, and display devices. A corresponding zirconium dioxide hydrosol is prepared by an aqueous solution method, and reactants are added to the zirconium dioxide hydrosol for multi-step reactions to obtain a transparent modified nano zirconium dioxide disperse solution. Then monomer, photoinitiator, solvent, and other functional additive are added to the nano zirconium dioxide disperse solution to obtain optical ink of the desired specification.
