ABSTRACT:
Several methods of printing filter material on a substrate to fabricate a color filter are provided. In one embodiment, the method includes: a) providing a substrate with a framework forming a cell, b) providing a liquid filter material ejection system with an inkjet print head, a liquid filter material, and a table supporting the substrate, and c) ejecting liquid filter material drops in the cell from the inkjet print head using a drop size printing process. The drops include smaller and larger drops. A color filter for a display device is also provided. In one embodiment, the color filter includes: a substrate, a framework attached to the substrate forming a cell, and a cured filter material fixed to the cell. The cured filter material is formed by ejecting multiple sizes of liquid filter material drops from an inkjet print head using a drop size switching printing process.
