Abstract:
A method for driving a plasma display panel in accordance with video signals, said plasma display panel including a plurality of discharge cells arranged in a matrix form, each of said discharge cells working as a display pixel, comprising the steps of:applying a reset pulse to all of said discharge cells to cause all of said discharge cells to discharge for resetting all of said discharge cells; applying a scanning pulse to each of said discharge cells to cause each of said discharge cells to selective-discharge for selecting either of light-emission and non-light-emission modes for each of said discharge cells on the basis of pixel data corresponding to a video signal for each of said discharge cells; and applying a sustaining pulse to allow only the discharge cell in the light-emission mode to discharge for repeating light emission, wherein said reset pulse comprises a first pulse voltage shift interval in which a pulse voltage changes gradually, reaches a minimum reset-discharge starting voltage, and exceeds the minimum reset-discharge starting voltage, and a second pulse voltage shift interval in which said pulse voltage changes steeply.
