Abstract: An inkjet printing method includes generating an initial sequence in which initial numbers are arranged in a matrix form, generating a correction sequence by correcting the initial numbers with correction numbers based on a variable range for a volume of droplets ejected into pixel areas and measurement error range for discharge volume of nozzles which discharge droplets to the pixel areas, and discharging droplets to the pixel areas while adjusting a discharge volume for each nozzle based on the correction sequence.

Abstract: A method of manufacturing a display device includes preparing a spraying device including a plurality of nozzles, dividing a discharge amount value range between a first reference discharge amount value and a second reference discharge amount value into k areas (k is a natural number), generating nozzle sets by combining n nozzles (n is a natural number) among m nozzles (m is a natural number, m≥n) for each of a plurality of nozzle groups, where the nozzle sets have a same discharge amount value as one another or different discharge amount values from one another, and each of the plurality of nozzle groups is defined by the m nozzles among the plurality of nozzles, and deriving an active nozzle group in which the nozzle sets are distributed in a preset manner in the k areas from the plurality of nozzle groups.
