摘要： When a sustain discharge corresponding to the display light is repeatedly produced by applying a drive pulse to a PDP which includes a fluorescent layer in the discharge cells, the drive pulse waveform is adjusted in accordance with the total number of sustain discharges. Furthermore, an auxiliary pulse of the same polarity as that of the sustain pulse is applied to the column electrodes in a period from after the application of a final scan pulse in the address process until the application of a leading sustain pulse. A period from the final sustain pulse until the time of the application of the leading pixel data pulse which is applied first in the write address process of the one subfield of the subsequent frame is made 1 millisecond (msec) or more.

摘要： When a discharge start voltage takes a normal value under the normal temperature, priming discharge starts at a time t1. In this case, at a time t3 that is later than the time t1 by a predetermined time t, a sustain driver control signal Ssud2 is raised to put a sustain electrode into the floating state to stop the priming discharge. When the discharge start voltage takes a higher value than usual under the high temperature, the priming discharge starts at a time t2. In this case, at a time t4 that is later than the time t2 by the predetermined time t, the sustain driver control signal Ssud2 is lowered to put the sustain electrode into the floating state to stop the priming discharge. With such a configuration, provided is a plasma display device capable of implementing excellent and stable display quality while maintaining constant, even if a discharge start voltage varies, the charge state in display cells after a priming period, and a drive method for such a plasma display device.

摘要： Disclosed is a method of driving a plasma display panel. In this method, one field corresponding to one image is divided into a plurality of sub-fields, and at least one second sub-field is arranged after a first sub-field. In the first sub-field, the method comprises a first step of forming wall charges with negative polarity near the scanning electrode and forming wall charges with positive polarity near the common electrode and the data electrode; a second step of adjusting an amount of the wall charges with negative polarity near the scanning electrode and an amount of the wall charges with positive polarity near the common electrode and the data electrode; a third step of generating a writing discharge in a selected display cell of the display cells; a fourth step of generating light emission for display; and a fifth step of erasing a part of the wall charges in the display cell which emits light in the fourth step. In the second sub-field, the method comprises the same steps as the third, fourth and fifth steps. A potential difference between a scanning electrode and a common electrode in each of the fifth steps in the first and second sub-fields is set to be smaller than a potential difference between a scanning electrode and a common electrode in each of the third steps in the first and second sub-fields.
