Patent ID: 8384623

Claim:
A plasma display device comprising: a plasma display panel that is driven by a subfield method and has a plurality of discharge cells, each of the discharge cells having a display electrode pair that includes a scan electrode and a sustain electrode, wherein the subfield method includes: setting a plurality of subfields in one field; setting a luminance weight for each of the subfields; and performing gradation display, each of the subfields having an initializing period, an address period, and a sustain period; an electric power recovering circuit for raising or falling a sustain pulse by resonating an inductor and an inter-electrode capacity of the display electrode pair; a clamping circuit for clamping the sustain pulse on a predetermined voltage; and a sustain pulse generating circuit for alternately applying a number of sustain pulses to the display electrode pairs in the sustain period, where the number is proportional to the luminance weights, wherein the sustain pulse generating circuit generates at least three kinds of sustain pulses that include a first sustain pulse serving as a reference with a first rising period, a second sustain pulse with a second rising period where the second rising period is longer than the first rising period, and a third sustain pulse with a third rising period, where the third rising period is shorter than the first rising period, wherein the first sustain pulse, the second sustain pulse, and the third sustain pulse are switched and generated within a period so that the second sustain pulse follows at least one of the first sustain pulse and the third sustain pulse, the third sustain pulse follows the first sustain pulse, and at least one first sustain pulse follows an other first sustain pulse.
