Droplet discharge device
A droplet discharge device includes a plurality of discharge heads configured and arranged to discharge droplets toward a plurality of pattern film formation regions disposed on a substrate with the pattern film formation regions including at least one narrow pattern film formation region that is narrower than the other pattern film formation regions. A number of the discharge heads corresponding to the narrow pattern film formation region is greater than a number of the discharge heads corresponding to one of the pattern film formation regions having an area that is larger than that of the narrow pattern film formation region.
1. A droplet discharge device comprising:
a plurality of discharge heads configured and arranged to discharge droplets toward a plurality of pattern film formation regions disposed on a substrate with the pattern film formation regions including at least one narrow pattern film formation region that is narrower than the other pattern film formation regions,
a number of the discharge heads corresponding to the narrow pattern film formation region being greater than a number of the discharge heads corresponding to one of the pattern film formation regions having an area that is larger than that of the narrow pattern film formation region.
2. The droplet discharge device according to claim 1 , wherein
the discharge heads corresponding to the pattern film formation regions are aligned in a scan direction, in which the substrate and the discharge heads move relative to one another, according to a sequence in which the pattern film formation regions are aligned in the scan direction.
3. The droplet discharge device according to claim 1 , wherein
the number of the discharge heads corresponding to the narrow pattern film formation region is greater than the number of the discharge heads corresponding to one of the pattern film formation regions having a width that is larger than that of the narrow pattern film formation region in a scan direction, in which the substrate and the discharge heads move relative to one another, when widths of the pattern film formation regions are different in the scan direction.
4. The droplet discharge device according to claim 3 , wherein
the number of the discharge heads corresponding to the narrow pattern film formation region is equal to or greater than the nth multiple of the number of the discharge heads corresponding to one of the pattern film formation regions having the width that is larger than that of the narrow pattern film formation region, when the width of the narrow pattern film formation region is 1/n of the width of the one of the pattern film formation regions.
