Plasma display panel having a plurality of bi-discharge sources and related method of sustaining discharge waveform

An electrode structure of a plasma display panel (PDP) having a plurality of bi-discharge sources comprising:

• a plurality of first, second and third electrodes disposed in parallel and spaced apart over a front substrate along a direction;
• and
• a plurality of barrier ribs supporting said first, second and third electrodes and disposed in parallel and spaced apart along a second direction orthogonal to said first direction,
• wherein each of second electrodes is centered between one of said first electrode and one of said plurality of third electrode and has a side induced as having a plurality of positive charges and an other side with a plurality of negative charges, and the positive charges and the negative charges are equal in amount.

A method of sustaining a discharge waveform in a plasma display panel (PDP) having a plurality of bi-discharge sources and a plurality of first, second and third electrodes, each of said bi-discharge sources corresponding to each of said first electrodes, each of said second electrodes and each of said third electrodes, comprising:

• providing a plurality of first voltages to said first electrodes, each of said first voltages applied to a corresponding first electrode of said first electrodes, and each of said first voltages having a waveform having a feature having a first sustain voltage and a second sustain voltage;
• and
• providing a plurality of third voltages to said third electrodes, each of said third voltages applied to one of said third electrodes, and each of said third voltages having a waveform having a feature having a third sustain voltage and a fourth sustain voltage,
• wherein an absolute value of said first sustain voltage is approximately identical to an absolute value of said fourth sustain voltage and an absolute value of said first sustain voltage is approximately identical to an absolute value of said third sustain voltage.
