A method of driving a discharge display panel includes steps (a) thru (c) as follows. In step (a), the number of sustaining discharge pulses is set for each sustaining discharge period so as to be proportional to a gray-scale weight assigned to each sub-field and so as to be inversely proportional to an average signal level of each frame. In step (b), when a frame has an average signal level at which ratios between the gray-scale weights of the respective sub-fields are not varied in accordance with the set number of sustaining discharge pulses, the driving is performed in accordance with the set number of sustaining discharge pulses. In step (c), when the frame has an average signal level at which the ratios between the gray-scale weights of the respective sub-fields are varied in accordance with the set number of sustaining discharge pulses, a signal level of image data is adjusted and the driving is performed in accordance with a gain inversely proportional to the average signal level regardless of the set number of sustaining discharge pulses. An apparatus for driving a discharge display panel comprises means for performing functions corresponding to steps (a) thru (c). |
