  • Patent number: 9832882
    Abstract: Provided herein is a conductive pattern making method and conductive pattern, the method including forming a groove such that its width in an inlet area is bigger than its width in an inner area; filling the groove with a conductive ink composition; and drying the conductive ink composition so that a solvent contained in the conductive ink composition inside the groove is volatilized to reduce the volume of the conductive ink composition.
    Type: Grant
    Filed: September 8, 2014
    Date of Patent: November 28, 2017
    Assignee: INKTEC CO., LTD.
    Inventors: Kwang-Choon Chung, Ji Hoon Yoo, Joonki Seong, Dae Sang Han, Nam-Boo Cho
  • Patent number: 9832881
    Abstract: Provided herein is a method for forming a transparent electrode film for display and the transparent electrode film for display, the method comprising forming an electrode pattern by printing a fine electrode pattern on a release film using a conductive ink composition; forming an insulating layer by applying an insulating resin on the release film on which the electrode pattern has been formed; forming a substrate layer by laminating a substrate on the insulating layer; and removing the release film.

  • Patent number: 9788418
    Abstract: Provided herein is a method for manufacturing a conductive transparent substrate, the method including forming a plurality of main electrodes on the substrate such that the main electrodes are distanced from one another; and forming a connecting electrode that electrically connects two or more main electrodes such that the plurality of main electrodes are grouped into a plurality of group electrodes that are electrically disconnected from one another, thereby producing a conductive transparent substrate with excellent transmittance in a process of high yield.
