    摘要: A first group of data drivers is connected to a sub-field processor, a first power recovery circuit, and a PDP, and a second group of data drivers is connected to a sub-field processor, a second power recovery circuit, and a PDP. The first and second groups of data drivers apply to the PDP data pulses that differ in phases. The first and second power recovery circuits generate a voltage for generating the data pulses to the first and second groups of data drivers due to LC resonance, and discharge and recover charges to and from the PDP. Recovery potentials of recovery capacitors in the first and second power recovery circuits are changed depending on the number of times of switching between discharges and non-discharges of discharge cells in the PDP.

    摘要: In each of sub-fields on each of lines in a plasma display device, it is judged whether or not all of a plurality of discharge cells on the line or the display cells whose number is not less than a predetermined number do not emit light, and at least one of a voltage applied to a scan electrode and a voltage applied to a sustain electrode on the line are kept at predetermined levels when all of the discharge cells or the discharge cells whose number is not less than the predetermined number do not emit light, or a pulse having the same phase as that of a sustain pulse applied to the sustain electrode 13 is periodically applied in place of a sustain pulse applied to the scan electrode 12 corresponding to the line, to decrease a charge or discharge current as well as to reduce the generation of electromagnetic waves.
