  • Publication number: 20080106198
    Abstract: A display apparatus includes a plasma display panel (PDP) and a filter having a panel side facing a display surface of the PDP and an opposing viewer side facing away from the display surface. The filter includes an external light shield having a first base unit and first pattern units. The first pattern units absorb external light from the viewer side and are substantially parallel to a first axis. The filter includes an electromagnetic interference (EMI) shield overlapping the external light shield. The EMI shield includes a second base unit and second pattern units. The second pattern units are conductive and substantially parallel to a second axis. An interior angle between the first axis and the second axis can be within a range of 40 to 50 degrees.

  • Publication number: 20080100535
    Abstract: A display apparatus includes a plasma display panel (PDP) and a filter. The PDP has a display surface, and the filter has a panel side facing the display surface of the PDP and an opposing viewer side facing away from the display surface. The filter includes a base unit. The filter also includes pattern units that absorb external light from the viewer side. The pattern units have boundaries that define widths of pattern tops and widths of pattern bottoms. A distance between a pattern top and a pattern bottom defines a pattern height. A distance between adjacent boundaries, of a pair of adjacent pattern units, at adjacent pattern bottoms can be less than a distance between the adjacent boundaries at adjacent pattern tops, less than the pattern height, and greater than a width of at least one of the pattern bottoms.

  • Publication number: 20080088535
    Abstract: A display apparatus includes a plasma display panel (PDP) having an upper substrate at which black matrices are disposed. The apparatus includes an external light shield having a panel side facing a display surface of the PDP and an opposing viewer side facing away from the display surface. The light shield includes a base unit and includes pattern units that absorb external light from the viewer side. The pattern units have boundaries defined by intersections of the pattern units and the base unit. The boundaries define widths of pattern tops disposed toward the panel side or the viewer side and define widths of pattern bottoms disposed toward the other of the panel side and the viewer side. A distance between a pair of adjacent black matrices is 4 to 12 times greater than a distance between adjacent boundaries, of a pair of adjacent pattern units, at adjacent pattern bottoms.

  • Publication number: 20060262036
    Abstract: An improved structure of a plasma display apparatus is provided. At least one of an integrated circuit and a driving board is formed over an edge potion of a frame for supporting a plasma display panel. Thus, the plasma display apparatus is manufactured to be thin and light, and also its manufacturing cost decreases.

  • Publication number: 20060125721
    Abstract: The present invention relates to a plasma display apparatus and an apparatus for driving a plasma display panel. The plasma display apparatus of the present invention comprises a connector into which a terminal of a driving connector is inserted, whereby the terminal of the driving connector and a terminal of the connector are brought in contact with each other and are thus electrically connected to each other. In accordance with the present invention, a driving drive can be replaced when failure occurs in the drive IC, and an additional member such as a TCP frame is not required.
