Abstract:
1. An apparatus for making a color filter with a plurality of filter elements aligned on a substrate, comprising: an inkjet head having a nozzle line comprising a plurality of nozzle groups, each of the nozzle groups including a plurality of nozzles; an ink supplying element for supplying a filter material to the inkjet head; a first-scan driving element for moving at least one of the inkjet head and the substrate in a first-scanning direction relative to the other; a second-scan driving element for moving one of the inkjet head and the substrate in a second-scanning direction relative to the other; a nozzle discharge controlling element for controlling the discharge of the filter material from the plurality of the nozzles; a first-scan controlling element for controlling the operation of the first-scan driving element; and a second-scan controlling element for controlling the operation of the second-scan driving element, wherein the second-scan controlling element is configured to control the second-scan driving element to move at least one of the inkjet head and the substrate in a second-scanning direction relative to the other so that at least a part of each nozzle group scans a same section of the substrate in the first direction and at least one adjacent nozzle group of a nozzle group at the inkjet head scans a same section of a substrate previously scanned by the nozzle group of the inkjet head.
