摘要： Image display quality of a plasma display apparatus is enhanced. For this purpose, the plasma display apparatus includes a number-of-sustain-pulses corrector for controlling the number of sustain pulses to be generated. The number-of-sustain-pulses corrector includes an all-cell light-emitting rate detection circuit (46), a partial light-emitting rate detection circuit (47), and a lookup table. The number-of-sustain-pulses corrector sets a correction coefficient that is read out from the lookup table in response to an all-cell light-emitting rate and a partial light-emitting rate as a first correction coefficient, and a recorrection coefficient that is based on the first correction coefficient. The number-of-sustain-pulses corrector adjusts the first correction coefficient and the recorrection coefficient, using an adjustment gain preset for each subfield in response to the magnitude of the luminance weight. The number-of-sustain-pulses corrector corrects the number of sustain pulses, using the first correction coefficient and the recorrection coefficient adjusted with the adjustment gain.

摘要： One field period includes a plurality of subfields each having (i) an initialization period in which a gradually descending sloping waveform voltage is applied to a scan electrode, (ii) a writing period in which a negative scan pulse voltage is applied to the scan electrode, and (iii) a sustain period. A sloping waveform voltage is generated by switching a minimum voltage in the sloping waveform voltage between a first voltage and a second voltage that has a lower voltage value than that of the first voltage. A number of subfields, in which an initialization is carried out by the sloping waveform voltage having the minimum voltage as the second voltage, is increased when a temperature of a plasma display panel is determined to be low as compared with when the temperature is determined to be not low.

摘要： In display of a 3D image on a plasma display panel, the plasma display apparatus achieves an excellent contrast with reduced crosstalk. For this purpose, the plasma display apparatus includes a driver circuit and a control signal generation circuit. The driver circuit drives the plasma display panel in a manner such that a subfield where an all-cell initializing operation is performed in the initializing period and a sustain discharge is caused in all the discharge cells in the sustain period is set as the first subfield of one field. The control signal generation circuit generates shutter opening/closing timing signals that include a timing signal for the right eye and a timing signal for the left eye. The control signal generation circuit sets both of the timing signal for the right eye and the timing signal for the left eye to OFF in the period of the first subfield.
