  • Patent number: 11912023
    Abstract: An inkjet printer configured to control the temperature of ink discharged from nozzles of an inkjet head is proposed. The inkjet printer includes: an inkjet head including a plurality of nozzles configured to discharge ink, an ink reservoir configured to store ink supplied to the inkjet head, a supply channel configured to supply the ink in the ink reservoir to the inkjet head, a pressure control device connected to the ink reservoir through a pressure control tube and configured to maintain the meniscus of the ink injected into the inkjet head, and the ink temperature control unit configured to control temperature of the ink discharged from the inkjet head.

  • Publication number: 20230187133
    Abstract: Proposed is a method of forming an electrode of an electronic device for manufacturing the electronic device, the method including forming a boundary line corresponding to an edge of an electrode pattern by inkjet printing, and forming an electrode body filled inside the boundary line by inkjet printing, wherein height and width of the electrode pattern are controlled by limiting ink printed in the electrode body formation such that the ink is prevented from going to an outside by the boundary line. The electrode body is formed after first forming the boundary line to prevent the spreading of ink ejected by inkjet printing, thereby increasing the precision of the electrode pattern which is the effect of inkjet printing and enabling the formation of the electrode having height which cannot be achieved by conventional inkjet printing.

  • Patent number: 11135853
    Abstract: The present invention relates to an ink circulation supply system for an inkjet head. The system is configured to supply ink to the inkjet head having a plurality of nozzles for ejecting the ink, and includes: a meniscus reservoir; a circulation reservoir; and an ante reservoir, the reservoirs where a first pressure connection pipe with a first pressure valve, a second pressure connection pipe with a second pressure valve, a first ink connection pipe, and a second ink connection pipe with an ink valve are provided, wherein when the internal pressure of the circulation reservoir is controlled to be lower than that of the meniscus reservoir, the ink stored in the meniscus reservoir is moved to the circulation reservoir without requiring use of a separate pump.
