A method of manufacturing of an ink (100) composition comprises a biphasic ligand exchange process. A first phase liquid (10) comprising a nonpolar solvent (11) with a colloidal suspension of nanoparticles (1) that are capped with a shell of non polar ligands (2) is contacted with a second phase liquid (20) comprising a polar solvent (21) with second ligand (3). The second ligand comprises at least one surface binding head group that has an affinity for binding to the nanoparticle; and an ionically charged tail group. The second ligands displace the first ligands to form a dispersion of the nanoparticles that are capped with a shell of the second ligands in the second phase liquid. The nanoparticles can be separated from the second phase liquid. The separated nanoparticles can be (re)dispersed in a printable liquid medium, e.g. used for printing a photoactive layer.

A manufacturing method of a display panel and the display panel are disclosed. The manufacturing method of the display panel generates electric fields between pixel electrode layers or between the pixel electrode layers and electrode layers. The electric fields have a horizontal component and a vertical component. The vertical component of the electric fields provides a force of depositing on the pixel electrode layers for charged groups in a material of light-emitting functional layers. Therefore, the method can prompt an ink of a light-emitting functional material to be deposited on the pixel electrode layers.
