  • Alternating-current plasma display panel
    Patent number: 6501221
    Abstract: An alternating-current plasma display panel having common electrode lines, scan electrode lines, and address electrode lines arranged between first and second substrates opposite and spaced apart from each other, the common electrode lines being parallel to the scan electrode lines, the address electrode lines being orthogonal to the common electrode lines and the scan electrode lines, to define corresponding pixels at respective crossings. The input terminals to which driving signals corresponding to the common electrode lines are applied are located opposite the input terminals to which driving signals corresponding to the scan electrode lines are input. The surface areas of respective common bus electrode lines and respective scan bus electrode lines increase toward corresponding input terminals.
