Abstract:
1. A method for forming a color filter on a substrate comprising: forming a plurality of boundary elements on the substrate, the boundary elements defining a plurality of pixel areas, each pixel area comprised of subpixel areas; selecting at least one subpixel area; applying a first fluid to the selected subpixel area, wherein the first fluid is a clear fluid or solvent and has surface properties that allow for a portion of a volume of the first fluid to extend beyond the boundary elements without wetting the boundary elements, the first fluid being substantially hydrophilic to the substrate but substantially hydrophobic to the boundary elements; and, emitting at least one drop of a second fluid into the first fluid within the selected subpixel area after the first fluid is applied to the selected subpixel area, the second fluid being a color liquid dispersing throughout the first fluid whereby color uniformity is achieved in the subpixel area.
