Patent ID: 7920103

Claim:
A plasma display apparatus comprising: a first substrate; a second substrate; a first electrode and a second electrode formed on the first substrate; and a sustain driver for applying sustain pulses to at least one of the first and second electrodes, wherein the sustain driver applies a voltage whose magnitude is ½ times as large as a sustain voltage to one of the first and second electrodes, and then, right after completion of a sustain discharge caused by one of the sustain pulses and before the completion of the sustain pulse, during a sustain period, begins to float the one of the first and second electrodes for a duration of 100 ns to 1000 ns, and wherein a floating period during which the one of the first and second electrodes is floated is one half the duration or shorter of a period during which the highest level of the sustain pulses continuously occurs.
