Structure and driving method of a plasma display panel

A driving method of a plasma display panel comprising:

• stripe-like anodes and barrier ribs formed on an upper face plate;
• first sustaining electrodes formed over the whole inner surface of a lower rear plate;
• and stripe-like cathodes formed on said first sustaining electrodes and insulated from said first sustaining electrodes by dielectric layers interposed between said first sustaining electrodes and cathodes, and respectively connected to external capacitors via a common node, thereby serving as second sustaining electrodes,
• wherein said first sustaining electrode is supplied with a pulse varying from ground potential to a first positive potential, from said first positive potential back to ground potential, and then from ground potential to a first negative potential;
• said second sustaining electrode is supplied with a pulse varying from ground potential to said first negative potential, from said first negative potential back to zero potential, and then from ground potential to said first positive potential;
• said anode is supplied with a writing pulse varying from a third positive potential to a fourth positive potential for data writing, when said pulses of said first and second sustaining electrodes are both at ground potential and said cathode is supplied with a negative scanning pulse varying from a third negative potential to a fourth negative potential;
• and
• said cathode is supplied with a negative erasing pulse having an amplitude equal to the difference between said third and fourth potentials, for erasing said written data after a predetermined time has elapsed.
