摘要： A method for driving a plasma display panel allows displaying an image of high quality having a large number of tones without causing a discharge cell to discharge erroneously. The width of a first sustaining pulse to be first supplied during each of the light emission sustaining processes to be executed during the display period of one field is set wider than that of the subsequent sustaining pulses, and the width of said first sustaining pulse is narrowed in accordance with the frequency of the light emission sustaining discharges occurring immediately before.

摘要： To improve display quality a reset step is executed for initializing all discharge cells into a light-emitting state only in the head sub-field within one field. Then pixel data is applied to column electrodes and scan pulses are applied to row electrodes for setting discharge cells to non-light-emitting state in all sub-fields within the field so that a discharge is generated for causing cells to emit light according to a weight of corresponding sub-field. Additionally, the pulse voltage of the scan pulse of the sub-field belonging to a group including the head sub-field is set larger than respective values of the scan pulse of a sub-field belonging to another group. In another embodiment at least one of the values of the pulse width and pulse voltage of the sustain pulse to be applied at the light-emission sustaining step is set larger than the value of the pulse width and the pulse voltage of the sustain pulse to be applied at some midpoint in the same light-emission sustaining step.

摘要： In the display of an image having a large black area, the luminance of black level of the display image is reduced so as to enhance the contrast. In the display of an image having a small black area, an address discharge is caused stably. Thereby, the image display quality is enhanced. For this purpose, a specified-cell initializing subfield where a forced initializing waveform is applied to predetermined scan electrodes and a non-initializing waveform is applied to the other scan electrodes in the initializing period, and a selective initializing subfield where a selective initializing waveform is applied to all the scan electrodes in the initializing period are set. A specified-cell initializing field having the specified-cell initializing subfield and the plurality of selective initializing subfields is set. The rate of regions where the gradation values of luminance are less than a predetermined value on the image display surface is calculated as a black area. The frequency of forced initializing waveforms generated is changed according to the size of the black area such that the frequency of forced initializing waveforms applied to the scan electrodes is reduced as the black area increases.
