Abstract: Disclosed is an image display device having functions for protecting an address driver. The image display device includes a panel provided with address electrodes and data electrodes, a scaler for converting an input image signal to fit into a resolution of the panel, an address driver and a data driver for driving the address electrodes and the data electrodes, respectively, in response to an image signal from the scaler, and a luminance control unit for comparing line by line changes of the image signal outputted from the scaler, changing luminance of the image signal outputted from the scaler, and changing the number of operations of the address driver. Such an image display device decreases a parasitic capacitance in an address driver for driving a PDP, to thereby prevent the address driver from being overloaded.

Abstract: A driving method of a surface discharge plasma display panel includes a resetting step, an addressing step and a sustained discharging step. In the resetting step, a first voltage is applied between the scan electrodes and the address electrodes to accumulate wall charges in the respective pixel by a facing discharge, and the wall-charges accumulated by the facing discharge are removed. In the addressing step, a second voltage is applied between a corresponding scan electrodes and selected address electrodes so that a facing discharge occurs, to form wall-charges in the selected pixels. In the sustained discharging step, a third alternating-current voltage is applied between the scan electrodes and the common electrodes so that a surface discharge occurs in the selected pixels.
