A plasma display device is provided. The plasma display device includes a plasma display panel (PDP) having an upper substrate, a lower substrate, a plurality of scan electrodes and a plurality of sustain electrodes formed on the upper substrate, and a plurality of address electrodes formed on the lower substrate; and a driver applying driving signals to the plurality of electrodes, wherein a reset discharge occurs in a part of discharge cells. The plasma display device can contribute to the reduction of dark-area luminance and the improvement of dark-room contrast ratio.

Plasma display device

Provided is a plasma display apparatus having a plasma display panel constituted of a plurality of discharge cells, and a driver for driving the panel. The apparatus includes a scan IC (integrated circuit) having a first switch turning on to apply a first signal to the panel, and a second switch turning on to apply a second signal to the panel, wherein, when the first signal applied to the panel changes into the second signal, the first and second switches are floated between an application period of the first signal and an application period of the second signal.
