Abstract:
Disclosed is an ejection volume compensation method of an inkjet printer for manufacturing an organic electroluminescent device pixel. The inkjet printer includes a plurality of nozzles and is configured to perform a plurality of print processes for the same pixel location. A target ejection volume for the next print process is selected so that an average of the target ejection volume and an actual ejection volume for the previous print process is equal to an ideal ejection volume. Also disclosed are an ejection volume compensation device for use with the inkjet printer, an inkjet printing device, and a non-transitory machine readable medium.

Claim (Index 9):
An inkjet printing device for manufacturing an organic electroluminescent device pixel, comprising:\n a printing device comprising a plurality of nozzles and configured to perform a plurality of print processes for a same pixel position; a controller operably connected to the printing device and configured to instruct the printing device to perform a test printing; and a measurement device operably connected to the controller and configured to measure respective ejection volumes of the plurality of nozzles in the test printing; wherein the controller is further configured to in the test printing:\n adjust respective drive signals for driving respective ones of the plurality of nozzles assigned for a first one of the plurality of print process to eject in dependence on respective ejection volumes of the respective nozzles assigned for the first print process measured by the measurement device, such that the respective ejection volumes of the respective nozzles assigned for the first print process are corrected to fall within a tolerance range around respective first target ejection volumes; \n derive respective second target ejection volumes of respective ones of the plurality of nozzles assigned for a second one of the plurality of print processes from the corrected ejection volumes of the respective nozzles assigned for the first print process, wherein the second target ejection volume of each of the respective nozzles assigned for the second print process is selected such that an average of the second target ejection volume and the corrected ejection volume of a corresponding one of the respective nozzles assigned for the first print process equals an ideal ejection volume; and \n adjust respective drive signals for driving the respective nozzles assigned for the second print process to eject in dependence on respective ejection volumes of the respective nozzles assigned for the second print process measured by the measurement device, such that the respective ejection volumes of the respective nozzles assigned for the second print process are corrected to fall within the tolerance range around the respective second target ejection volumes.
