  • Publication number: 20060068083
    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.

  • Publication number: 20060027383
    Abstract: An electromagnetic interference (EMI) shielding filter includes a conductive pattern for shielding electromagnetic waves; and blackened layers formed on a surface of the conductive pattern. The electromagnetic interference (EMI) shielding filter is manufactured by preparing a base film; forming on the base film a first blackened layer, a conductive layer, and a second blackened layer in sequence; and patterning the first blackened layer, the conductive layer, and the second blackened layer by using a same mask, and forming on front and rear surfaces of an EMI shielding layer a conductive pattern comprising the first and second blackened layers.

  • Publication number: 20050179368
    Abstract: Disclosed herein is a plasma display panel in which afterimage is improved. The plasma display panel according to the present invention includes a panel unit having an upper plate and a lower plate, a frame that supports circuitry, and a conductive material formed between the panel unit and the frame. As such, a conductive material is formed on a bottom surface of a lower plate of a panel. Thus, charges introduced into the lower plate are properly controlled to improve the waveform stability of the panel. Also, a charge characteristic is improved to implement a stable operation. Accordingly, an afterimage time can be reduced. Further, a sheet of a low hardness and light weight is used. It is thus possible to absorb shock and noise of a PDP, accomplish light weight of the PDP and reduce the materials of the sheet.

  • Publication number: 20050029938
    Abstract: A glass composition for a plasma display panel (PDP) and its fabrication method are disclosed. The composition, comprising a ZnO—B2O3 group and alkaline earth metal oxide, is environment-friendly, has a high discharge efficiency and is used as various PDP dielectric materials. The fabrication method allows to compose the low melting point unleaded non-alkali glass composition at a low cost.

  • Publication number: 20050017640
    Abstract: A plasma display panel (PDP) and its fabrication method are disclosed. The PDP includes a dielectric transfer film containing a ceramic pigment instead of a conventional upper dielectric layer, so that a color purity and a contrast ratio can be increased, the thickness of the dielectric thin film can be uniform, and a voltage margin and discharging can be uniform.
