  • Publication number: 20080136329
    Abstract: Disclosed are a plasma display panel and a method for manufacturing the same. The method includes preparing a first substrate including an address electrode, a dielectric and a barrier rib, applying a first dielectric to a second substrate including a pair of sustain electrodes, applying a plurality of second dielectrics to the first dielectric with a dispensing system having a nozzle equipped with a plurality of reverse-trapezoid injection ports, such that the second dielectrics have a differential structure, drying the first and second dielectrics, followed by baking, forming a protective film on the first and second dielectrics, and joining the first substrate to the second substrate.

  • Patent number: 6997536
    Abstract: A device and method for fabricating a display panel having ink-jet printing applied thereto is disclosed, in which it is possible to simplify fabricating process steps and to reduce production cost, and to prevent pattern failure. The device includes a stag having a hole and supporting a substrate; one or more ink-jet heads having nozzles spraying pattern forming solution onto the substrate; and one or more cameras positioned below the stage so as to monitor the nozzles through the holes.

  • Patent number: 6827426
    Abstract: A method for fabricating a plasma display panel can improve contrast of a panel by using an inkjet printing method in forming a fluorescent layer in the fabrication process of the plasma display panel. Also, after charging a liquid flake of fluorescent ink with a charge of a predetermined polarity, contrast of the panel can be improved by inducing the injection direction of the liquid flake by charging an address electrode with a charge having an opposite polarity to the liquid flake so that the charged liquid flake can be printed in the center portion of the cell region.
