  • Modified conductor array for plasma display panel
    Patent number: 4278909
    Abstract: In plasma display panels requiring interstitial spacer elements within the display area to provide and maintain a uniform discharge gap, the spacers are positioned between lines which constitute the display. The lines adjacent the spacer elements experience a significant decrease in operating margin. This margin decrease is compensated for by either jogging the lines adjacent the spacers outwardly, by widening the lines in the affected areas or a combination of both. Various embodiments for providing this compensation are illustrated and described.
