Abstract
A method of driving a plasma display panel for generating picture or image with high quality while suppressing luminance to a low level in the display in black. One field for image display is composed of at least two different types of subfields first and second subfields. In the first subfield (subfield A), a reset period is provided in which after a priming pulse (Pp) having a voltage value and a pulse width has been applied between X- and Y-row electrodes for causing discharge to occur in all of pixels, then the voltage applied between both the electrodes is set to zero for erasing wall charge after the discharge of all of the pixels, while in the second subfield (subfield B), a reset period is provided in which an erasing pulse (Ep) having a voltage value and a pulse width for causing only the pixels discharged in the preceding subfield to be discharged has been applied for allowing only the pixels discharged in the preceding subfield to be discharged, the wall charge is erased by setting to zero the voltage applied between the X- and Y-row electrodes.
