ABSTRACT:
A plasma display panel includes barriers arranged in a striped form on a front plate, a sustaining electrode formed over the entire surface of a backing plate, insulating layers coated on the sustaining electrode in a matrix form, first electrodes formed on the first insulating layers in a striped form, second insulating layers coated on the first electrodes in a striped form, and second electrodes formed on the second insulating layers. In the driving method, a pulse train having a predetermined period, generated so as to have an amplitude equivalent to a second voltage subtracted from a first voltage and riding on the second voltage, is applied to the sustaining electrode; one pulse generated so as to have an amplitude equivalent to a fourth voltage subtracted from a third voltage, is applied to the first electrodes when the pulse train equals the second voltage and rides on the fourth voltage; sequential pulses generated so as to have an amplitude equivalent to a sixth voltage subtracted from a fifth voltage, is applied to the second electrodes also when the pulse train equals the second voltage; a voltage for creating discharge is equivalent to the sixth voltage subtracted from the third voltage and greater than a discharge firing voltage; and a voltage for maintaining discharge once created while suppressing the discharge if not created, is equivalent to the fifth voltage subtracted from the first voltage and greater than a minimum discharge sustaining voltage but smaller than the discharge firing voltage.
