Liquid material arrangement method, color filter manufacturing method, and organic EL display device manufacturing method
A liquid material arrangement method is a method for arranging a liquid material in a plurality of prescribed regions on a substrate by discharging the liquid material as a droplet from a nozzle. The liquid material arrangement method includes: performing a discharge information acquiring step for acquiring discharge information of the nozzle including a landing position and a discharge quantity of the droplet discharged from the nozzle by a nozzle check; performing a second pattern generating step for generating a second dot pattern, which is an arrangement pattern for arranging a prescribed number of droplets, by selecting at least one non-discharge dot from a first dot pattern, which is an arrangement pattern for arranging more droplets than the prescribed number of droplets, based on the discharge information; and performing a liquid material arranging step for arranging the liquid material in the prescribed regions based on the second dot pattern.
1. A liquid material arrangement method for arranging a liquid material in each of a plurality of units of prescribed region on a substrate by discharging the liquid material as a droplet from a nozzle, the liquid material arrangement method comprising:
performing a discharge information acquiring step for acquiring discharge information of the nozzle including a landing position and a discharge quantity of the droplet discharged from the nozzle by a nozzle check;
performing a second pattern generating step for generating a second dot pattern, which is an arrangement pattern for arranging a prescribed number of droplets, by selecting at least one non-discharge dot from a first dot pattern, which is an arrangement pattern for arranging more droplets than the prescribed number of droplets, based on the discharge information and by deleting the non-discharge dot from the first dot pattern for all of the units of the prescribed region; and
performing a liquid material arranging step for arranging the liquid material in each of the units of the prescribed region based on the second dot pattern,
a number of the selected non-discharge dot being the same for each of the units of the prescribed region.
2. The liquid material arrangement method according to claim wherein
the performing of the second pattern generating step includes selecting the non-discharge dot by determining the discharge information respectively for each of the units of the prescribed region.
3. The liquid material arrangement method according to claim 1 , wherein
the units of the prescribed region are partitioned by banks.
4. A color filter manufacturing method comprising:
performing the liquid material arrangement method according to claim 1 to discharge a plurality of color materials as the liquid material onto the prescribed regions on the substrate, respectively; and
curing the arranged liquid material to form a plurality of colored parts in the units of the prescribed region with each of the colored parts corresponding to a pixel region.
5. An organic EL display device manufacturing method comprising:
performing the liquid material arrangement method according to claim 1 to discharge an organic EL material as the liquid material onto the units of the prescribed region of the substrate, respectively; and
curing the arranged liquid material to form luminescent elements in the units of the prescribed region with each of the luminescent elements corresponding to a pixel region.
