Abstract:
1. A method for discharging droplets onto a discharge area, the discharge area including an edge portion, the method comprising: providing a plurality of discharge heads, each with a plurality of nozzles, the plurality of discharge heads being moveable in a scanning direction relative to the discharge area, the plurality of discharge heads being spaced apart relative to each other in a first direction, the plurality of heads being offset relative to each other in a second direction substantially perpendicular to the first direction, the plurality of discharge heads having an overlapped area where the plurality of discharge heads overlap each other when viewed from the scanning direction; discharging droplets of a plurality of different functional liquids from the plurality of discharge heads; and moving the plurality of discharge heads in the scanning direction relative to the discharge area such that the overlapped areas scan the edge portion of the discharge area in a single pass, and such that the nozzles of the overlapped areas discharge droplets of the plurality of different functional liquids onto the edge portion in the single pass, the single pass being a continuous, unidirectional movement of the plurality of discharge heads relative to the discharge area.
