Abstract:
A plasma display panel driving device for driving, in accordance with picture signals, a plasma display panel, in which a plurality of discharge cells supporting display pixels are arranged in a matrix, comprising:resetting means for generating a resetting pulse for causing the occurrence of a reset discharge, which initializes each of said discharge cells to one of either an light-emitting cell state or a non-light-emitting cell state, and applies the resetting pulse to each of said discharge cells; pixel data writing means for applying to each of said discharge cells a scanning pulse for causing the occurrence of a selective discharge, which selectively sets said discharge cells to either said non-light-emitting cell state or said emission-cell state in accordance with pixel data corresponding to said picture signals; emission sustaining means for applying to each of said discharge cells a sustaining pulse for causing the occurrence of a sustain discharge, which causes light to be emitted repeatedly only from said discharge cells that are in said light-emitting cell state; a light sensor for detecting an ambient illuminance of said plasma display panel; and resetting pulse waveform adjusting means for adjusting the level change rate at the leading edge portion of said resetting pulse in accordance with said illuminance.
