Abstract
A plasma display device includes a controller for generating and outputting scan data corresponding to a scan electrode to which a scan pulse is applied during an address period, and outputting the same to a scan integrated circuit having a plurality of output terminals coupled to the scan electrodes for driving the scan electrodes. During an address period, the scan integrated circuit applies a first voltage through an output terminal corresponding to the scan data, and applies a second voltage that is greater than the first voltage through another output terminal. The configuration enables the plasma display device to freely control the order of the scan electrodes to which the first voltage is applied according to the scan data.
