Abstract
Embodiments of the present disclosure disclose a preparation method of high refractive index ink and a display panel. The method for preparing high refractive index ink, comprising: providing a nano-metal oxide dispersion; performing ozone treatment on the nano-metal oxide dispersion to obtain the ozone treated nano-metal oxide dispersion; mixing the ozone-treated nano-metal oxide dispersion with a plurality of preset solutions according to a predetermined weight ratio to form a mixed solution; performing ball milling treatment on the mixed solution to obtain the ball-milled mixed solution; and heating the ball-milled mixed solution to obtain the high refractive index ink. According to the present disclosure, the nano-metal oxide dispersion is subjected to ozone and ball milling treatment, thereby improving the dispersibility of the nano-metal oxide particles in the high refractive index ink.
