Abstract:
A method for making a color filter with a plurality of filter elements aligned on a substrate, comprising:moving an inkjet head relative to the substrate or moving the substrate relative to the inkjet head in a first-scanning direction, wherein the inkjet head has a nozzle line having a plurality of nozzle groups, the nozzle groups including a first nozzle group and a second nozzle group, each nozzle group including a plurality of nozzles; selectively discharging a plurality of filter materials from the plurality of nozzles to form the plurality of filter elements; and moving the inkjet head relative to the substrate or moving the substrate relative to the inkjet head in a second-scanning direction so that a filter material discharged from a first nozzle of the first nozzle group and a filter material discharged from a second nozzle of the second nozzle group coincide with the same filter element on the substrate, the first-scanning direction and the second-scanning direction intersecting each other, wherein the inkjet head moves relative to the substrate or the substrate moves relative to the inkjet head by a distance corresponding to an integral multiple of the length of one of the nozzle groups in the second-scanning direction.
