摘要:
A droplet discharge method includes performing a plurality of scans in which a discharge head and a substrate are scanned relative to each other, discharging droplets of a plurality of types of functional liquid from the discharge head onto a plurality of prescribed portions on the substrate that are arranged in a matrix while the discharge head and the substrate are scanned. The discharging of the droplets includes discharging the droplets onto the prescribed portions over the plurality of scans so that centers of newly discharged droplets are made to land at one of positions that overlap with centers of landing positions of the droplets already discharged to the prescribed portions and positions that are offset in a row direction and in a column direction of the matrix from the centers of the landing positions of the droplets already discharged to the prescribed portions.
摘要:
A method is provided to reliably form shot drops on all of a plurality of pixel areas. The method comprises a step of forming a plurality of shot drops by ejecting droplets from a plurality of nozzles of a drawing apparatus to a plurality of pixel areas on a substrate. The step of forming the plurality of shot drops includes a step of forming additional shot drops near predetermined ones of the plurality of shot drops.
摘要:
A discharge amount measurement method is configured to measure a discharge amount of a liquid discharged from at least one nozzle of a droplet discharge head. The discharge amount measurement method includes discharging the liquid as a droplet from the at least one nozzle of the droplet discharge head by a number of discharges that is set to obtain a measurable quantity by driving the droplet discharge head based on measurement discharge data that is substantially identical to data used when a drawing pattern is formed by discharging the liquid from the at least one nozzle of the droplet discharge head, measuring the discharge amount of the liquid discharged from the at least one nozzle of the droplet discharge head, and calculating an average discharge amount based on the discharge amount and the number of discharges.
摘要:
A method for placing a liquid material includes a) discharging the liquid material from a plurality of nozzles into a single region of a substrate during a scan of the substrate performed by a head having a nozzle group including the plurality of nozzles using a first electric pulse, and b) discharging the liquid material into the single region from the plurality of nozzles during the scan using a second electric pulse. The first and second electric pulses are supplied to a pressure controller to control pressure of a liquid chamber communicated with the plurality of nozzles so as to cause the plurality of nozzles to discharge the liquid material. The first and second discharge steps are performed by using the same plurality of nozzles during the same scan.
