DROPLET DISCHARGE APPARATUS AND DROPLET DISCHARGE METHOD

Abstract: in a droplet discharge method, a plurality of grids corresponding to areas of a substrate are set. a discharge amount for each grid is determined based on a difference in discharge amount according to a temperature change of ink to be discharged from nozzles that are designated for the plurality of grids respectively. an ink drop map for discharging ink having the discharge amount for each grid is created. droplets are discharged through the nozzles according to the ink drop map to form a thick film having a predetermined thickness on the substrate.
