Document Type and Number:
WIPO Patent Application WO/2022/145252
Kind Code:
A1
Abstract:
Provided is a method for printing ink containing luminescent nanocrystal particles in inkjet style while minimizing deactivation of the luminescent nanocrystal particles in a device. This method for printing ink containing luminescent nanocrystal particles uses an inkjet printing device comprising an ink storage container and an ejection head, wherein the printing method comprises an ink supply step in which some of the ink containing luminescent nanocrystal particles stored in the ink storage container is supplied to the ejection head and an ejection step in which the ink containing luminescent nanocrystal particles is ejected from the ejection head, the ink storage container is configured such that the volume of an ink storage space in which the ink containing luminescent nanocrystal particles is stored can be changed, the ink storage space is shrunk as the ink containing luminescent nanocrystal particles is supplied in the ink supply step, and outside air is prevented from flowing into the ink storage container by maintaining the ink storage space in the shrunken state.
