  • Patent number: 7920104
    Abstract: 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.
