Abstract:
1. A liquid droplet-discharging device comprising: 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 controller including a memory for memorizing pattern data corresponding to driving nozzles that are selected from the plurality of nozzles in each of a plurality of discharged regions, the memory partitioning a drew region of the substrate into the plurality of discharged regions for every discharging frequency state M 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, wherein the patterned data is 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, the patterned data is data that allocates nozzles located adjacent to each other to different blocks designated as (3N+1), (3N+2), and (3N+3) where N is an integer more than or equal to zero and makes each of the plurality of blocks correspond to each of the plurality of discharged regions; the controller regulates the plurality of nozzles associated with a respective block designated as (3N+1) to discharge when the discharging frequency state becomes (3M+1) where M is an integer more than or equal to zero and regulates the remaining nozzles to not discharge; the controller regulates the plurality of nozzles associated with a respective block designated as (3N+2) to discharge when the discharging frequency state becomes (3M+2) and regulates the remaining nozzles to not discharge; the controller regulates the plurality of nozzles associated with a respective block designated as (3N+3) to discharge when the discharging frequency state becomes (3M+3) and regulates the remaining nozzles to not discharge.
