Abstract
A liquid droplet-discharging device comprises: a droplet-discharging head having a plurality of nozzles that are arranged in a predetermined direction and discharge liquid droplets; a scanning unit for relatively moving the droplet-discharging head and a substrate toward a scanning direction: a memory memorizing pattern data corresponding to driving nozzles that are selected from the plurality of nozzles in each of a plurality of discharged regions, by partitioning a drew region of the substrate into the plurality of discharged regions every discharging frequency along a scanning direction of the substrate; a transferring unit for developing the patterned data memorized by the memory into a plurality of data to be divided and transferring the divided data to the liquid droplet-discharging head in order; and an output unit for outputting a driving signal that drives a driving nozzle selected by the divided data to discharge the liquid droplets. The patterned data are data that allocates the plurality of nozzles to a plurality of blocks and corresponds each of the plurality of blocks to each of the plurality of discharging regions.
