摘要： A plasma display device performing display control by utilizing plasma discharge includes a panel having a plurality of address electrodes and a plurality of display electrodes disposed to intersect with the address electrodes, and a drive circuit performing address discharge drive for selectively producing a discharge in cells between the address electrodes and the display electrodes, and display discharge drive for applying to the display electrode a display drive pulse having a voltage increasing with such a gradient as to continuously produce a discharge current in the selected cell. In the display discharge drive performed after the address discharge drive, a display drive pulse with an increasing voltage of gentle gradient is applied to the display electrode, thereby producing faint discharges continuously in the selected cell during the increase of the voltage applied to the display electrode. Display luminance is controlled by the above ramp-wave discharge. In such the ramp-wave discharge, differently from the conventional strong discharge, faint discharges are produced a plurality of times while the display drive pulse is being applied, enabling improvement on the discharge efficiency, and reduction of power consumption.
