  • Patent number: 8816938
    Abstract: A large-scale display device having a plurality of display units which each include a plurality of elongated plasma tubes each filled with a discharge gas, and at least one pair of display electrodes disposed outside the plasma tubes, voltage applying means which applies a drive voltage to the display electrodes to cause electric discharge in the plasma tubes for display. Vertically adjoining ones of the display units respectively have adjoining portions which are offset thicknesswise from each other for prevention of contact between the plasma tubes of the vertically adjoining display units. The voltage applying means is disposed away from the adjoining portions of the vertically adjoining display units.

  • Patent number: 8089210
    Abstract: This invention provides a plasma tube array-type display sub-module capable of reducing a possibility of occurrence of troubles on a plasma tube array during a manufacturing process even in a case where irregularities are formed on the back side of the plasma tube array, and a display device. The plasma tube array-type display sub-module comprises a plasma tube array including a plurality of plasma tubes arranged in parallel, the plasma tube array being held between an address electrode support sheet having address electrodes formed thereon and a display electrode support sheet having display electrodes formed thereon, wherein the plasma tube array is fixed to a sub-module frame through an intermediate layer that is made of a material more flexible than that of the plasma tube array and can deform along the irregularities on the address electrode support sheet of the plasma tube array.

  • Publication number: 20100237759
    Abstract: A plasma tube array-type display sub-module commonized to allow a universal design, and a large-screen display device configured with the plural PTA sub-modules are easily provided. A front-side supporting sheet is provided, on front face of a plasma tube array with a plurality of display electrode pairs in which X and Y electrodes extend in the direction intersecting the plasma tubes. At both ends of the front-side supporting sheet, connection boards are provided in which an X connector connected to the X electrode and a Y connector connected to the Y electrode are provided separately in the direction in which the display electrode pairs extend. A flexible cable connects between the same type of connectors of the adjacent PTA sub-modules and thereby the PTA sub-modules are joined together.

  • Publication number: 20090315809
    Abstract: A display device comprising a plurality of plasma tube array-type display sub-modules joined with a high precision is provided. The shapes of the display electrodes on the display electrode support sheets are identical in all of the plasma tube array-type display sub-modules joined. The plurality of plasma tube array-type display sub-modules are joined by a first connector joining the plasma tube array-type display sub-modules to one another, and a second connector connecting the plasma tube array-type display sub-modules to drive circuit substrates.
