Abstract

A first fluid, e.g., a clear solvent, is printed in a subpixel of a color filter prior to printing droplets of a second fluid such as colored liquid into the subpixel areas. This first fluid could have surface wetting properties such that it is hydrophilic to the substrate (glass) but hydrophobic to the boundary (black matrix). Therefore, the first fluid would flow over the entire subpixel area, but not onto the black matrix. The first fluid would then allow color fluid to disperse uniformly throughout the subpixel. This first fluid may also be used in additional embodiments to re-liquify a dry or partially dry color subpixel, so that color non-uniformities can be corrected.
