摘要： A plasma display apparatus includes a plasma display panel having a plurality of sustain electrodes and a plurality of scan electrodes, a driver circuit to apply sustain pulses to the plurality of sustain electrodes and the plurality of scan electrodes to generate sustain discharges, and a control circuit to control the driver circuit such that a total light emitting pulse count defined as a total number of sustain pulses in one display frame is set equal to a predetermined pulse count defined as a function of a display load ratio, and such that the total light emitting pulse count is set lower than the predetermined pulse count upon detecting a predetermined condition, wherein the control circuit is configured to cause the driver circuit to selectively generate first sustain pulses with timing for clamping to a predetermined voltage being first timing and second sustain pulses with timing for clamping to the predetermined voltage being second timing, and configured to cause a ratio between a number of the first sustain pulses and a number of the second sustain pulses to be different between a case of the total light emitting pulse count being the predetermined pulse count and a case of the total light emitting pulse count being smaller than the predetermined pulse count.
