PLASMA DISPLAY DEVICE AND METHOD FOR DRIVING PLASMA DISPLAY PANEL

摘要

Image display qualities of a plasma display device are improved by reducing luminance nonuniformity. The plasma display device is provided with a sustain pulse generating circuit, which has a power recovery circuit and a clamp circuit, generates sustain pulses in a sustain period and alternately applies the sustain pulses to a pair of display electrodes. The sustain pulse generating circuit generates at least two kinds of sustain pulses, i.e., a first sustain pulse to be reference, and a second sustain pulse having steeper startup compared with the first sustain pulse. The sustain pulse generating circuit alternately generates a first sustain pulse group and a second sustain pulse group. The first sustain pulse group is configured by generating the same number of first sustain pulses and the second sustain pulses so that the same number of the first sustain pulses and the second sustain pulses are applied to the scanning electrode and the sustain electrode, respectively. The second sustain pulse group is configured so as to continuously generate the first sustain pulses of the number the same as the number of the sustain pulses of the first sustain pulse group.
