Abstract:
1. A drawing system for discharging a liquid material including a functional material from a plurality of nozzles to a plurality of pixel regions on a substrate in synchronization with a relative movement of the substrate and the nozzles to form pixel formation elements, the drawing system comprising: a memory unit configured and arranged to store at least nozzle information in which the nozzles are ranked according to discharge characteristics and first arrangement information that indicates an arrangement of each of the nozzles with respect to each of the pixel regions in the relative movement, the discharge characteristics including landing position deviation of the droplets, discharge quantity abnormality, and missing discharge, and the first arrangement information including selection information indicative of the nozzles selected for discharging the droplets; an arrangement information generation unit configured and arranged to generate second arrangement information, in which the first arrangement information is corrected based on the nozzle information, by correcting the first arrangement information so that at least one of the nozzles for each of the pixel regions is selected not to discharge the liquid material according to rankings of the nozzles, and at least one of the nozzles is selected to discharge the liquid material to make up for a deficiency in the liquid material discharged onto each of the pixel regions; and a droplet discharge device configured and arranged to select one of the first arrangement information and the second arrangement information and to discharge droplets of the liquid material on each of the pixel regions from the nozzles according to the one of the first arrangement information and the second arrangement information selected.
