    • A driving method of plasma display panels is disclosed. This method can suppress a dark belt occurring in displaying a video of a lower part of grayscale. One field includes plural sub-fields, and each one of the sub-fields has an addressing period during which a scan pulse is applied to the scan electrodes and a data pulse is applied to the data electrodes, and a sustaining period during which a sustain pulse is applied to the scan electrodes and the sustain electrodes. A time interval between a scan pulse applied lastly during the addressing period and a sustain pulse applied firstly during the sustaining period is defined as a last pulse-interval. The last pulse-interval of at least one sub-field of a lower part of grayscale, which lower part is darker than a predetermined level of the grayscale, is set longer than the last pulse-intervals of the other sub-fields.

    • An exemplary modulator apparatus for a polar modulation transmitter includes a phase difference extractor, a phase modulator, and a coarse phase controller. The phase difference extractor is configured to extract +180° and −180° phase differences represented in a phase-difference modulation signal in a phase modulation path of the polar modulation transmitter, or extract other phase differences exceeding other predetermined phase difference thresholds, to produce a bandwidth-reduced phase-difference modulation signal. The phase modulator includes a controlled oscillator having a tuning port that is modulated by phase differences represented in the bandwidth-reduced phase-difference modulation signal, to produce a phase-modulated RF carrier signal. The coarse phase controller operates to effectuate phase reversals or introduce other coarse phase changes into the phase-modulated RF carrier signal, based on the phase differences extracted from the original phase-difference modulation signal.
