Abstract:
1. A plasma display apparatus comprising: a plasma display panel in which a first substrate and a second substrate are disposed with a gap there between, a plurality of pairs of first and second electrodes being disposed on the first substrate, a plurality of third electrodes being disposed on the second substrate, a plurality of discharge cells being formed between the first substrate and the second substrate, and the first, the second and the third electrodes being included in the discharge cells; and a driving circuit that drives the plasma display panel in such a manner that one field includes a set-up period, a write period, a discharge sustain period and an erase period, wherein in the discharge sustain period, the driving circuit applies pulses such that at least one of a plurality of pulses applied in a later part of the discharge sustain period has a pulse width smaller than an initial pulse applied in the discharge sustain period and larger than pulses applied in an earlier part of the discharge sustain period except for the initial pulse, in the set-up period, the driving circuit applies a pulse including a portion having a waveform that falls from positive to negative on a trailing edge, and in the erase period, the driving circuit applies a pulse gradually rising on a leading edge.
