  • Patent number: 7741778
    Abstract: The present invention aims to ensure luminosity while improving evacuation characteristics in a plasma display panel. First ribs (112) that separate a plurality of cells from each other and second ribs (113) are formed in stripe patterns so as to intersect with each other on a surface of a first substrate (107), a surface of a second substrate opposes tops of the first ribs, and a height of the ribs at intersections (112b) of the first and second ribs intersect is lower than other parts of the first ribs (112a).

  • Patent number: 7728794
    Abstract: Set-up, write, sustain and erase pulses are variously applied to a plasma display panel using a staircase waveform in which the rising or falling portion is in at least two steps. These staircase waveforms can be realized by adding at least two pulses. Use of such waveforms for the set-up, write and erase pulses improves contrast, and use for the sustain pulses reduces screen flicker and improves luminous efficiency. This is of particular use in driving high definition plasma display panels to achieve high image quality and high luminance.

  • Patent number: RE43083
    Abstract: A gas discharge panel includes a first substrate and a second substrate. A plurality of display electrode pairs which are each made up of a sustain electrode and a scan electrode are formed on the first substrate, and the first substrate and the second substrate are set facing each other with a plurality of barrier ribs in between so as to form a plurality of cells. In this gas discharge panel, at least one of the sustain electrode and the scan electrode includes: a plurality of line parts; and a discharge developing part which makes a gap between adjacent line parts smaller in areas corresponding to channels between adjacent barrier ribs than in areas corresponding to the barrier ribs.
