  • Patent number: 6496163
    Abstract: A memory type alternating current plasma display panel has two pixel blocks on both sides of a spacer wall, and scanning/sustain electrode pairs for the two pixel blocks respectively have the innermost sustain electrodes closer to the spacer wall than the associated scanning electrodes so as to increase an offset margin during assemblage of panel structures.
    Type: Grant
    Filed: August 18, 1998

  • Patent number: 6252568
    Abstract: In a conventional plasma display panel drive method, making the sustaining discharge pulse bipolar with respect to the data electrode potential prevents stable discharge in the leading sustaining discharge pulse, thereby complicating continuation to second and subsequent sustaining discharges. The plasma display panel drive method of this invention makes the potential of the leading sustaining discharge pulse a negative polarity to the data electrode potential, and moreover, makes the high-potential side of second and subsequent sustaining discharge pulses positive polarity to the data electrode potential, and makes the low-potential side negative polarity with respect to the data electrode potential.
