摘要： A method of driving a plasma display panel minimizes occurrence of complementary color ghost images (afterimage). Reset pulses are applied to a plurality of row electrode pairs to trigger a reset discharge in all discharge cells. The reset pulses include a first reset pulse that is applied to one of the row electrodes of each row electrode pair and a second reset pulse that is applied to the other row electrode at the same time that the first reset pulse is applied and has a polarity opposite that of the first reset pulse. The first and second reset pulses have different voltage levels.

摘要： A plasma display device and a method of driving a plasma display panel are provided for improving the contrast without degrading the image quality. Each of display cells formed on the plasma display panel has a magnesium oxide layer containing magnesium oxide crystals. The magnesium oxide crystals are excited by an electron beam irradiated thereto and emit cathode luminescence light having a peak in a wavelength range of 200 to 300 nm. In order to trigger a rest discharge in all the display cells, each row electrode pair of the plasma display panel is applied with a reset pulse which has a particular pulse waveform. The voltage value of this reset pulse slowly changes over time to reach a peak voltage value.

摘要： A driving apparatus of a plasma display panel performs allows image display in a desired way. When discharge cells are driven to repetitively execute a sustain-discharge by the application of sustaining pulses to row electrodes the number of times corresponding to subfields, a ratio of changes of a voltage value in a trailing interval of the last sustaining pulse among those sustaining pulses is set to be milder than that of a voltage value in a trailing interval of the sustaining pulse which is applied just before the last sustaining pulse. Further, description has been made for a driving method of a plasma display panel which can perform an image display of high quality by performing a proper selective discharge while preventing an erroneous discharge of the discharge cells in a pixel data writing step. A trailing edge portion of the sustaining pulse which is applied finally among the sustaining pulses applied in a light emission sustaining step has an undershoot part below a ground potential.

摘要： A method of driving a plasma display panel for improving the contrast at low power consumption while suppressing spurious borders, and for stabilizing selective discharge to improve the display quality. The method selects either a first mode in which the number of times of light emission in a light emission sustaining stage in each subfield (SF) within a SF group in one field display period is set to a first value, or a second mode in which the number of times of light emission in the light emission sustaining stage in each SF within the SF group is set to a second value lower than the first value. When the second mode is selected, at least one of the values of a pulse width and a pulse voltage of a scanning pulse in each SF within the SF group is set larger than the corresponding value of the pulse width or the pulse voltage of the scanning pulse in each SF within the SF group when the first mode is selected.

摘要： A plasma display panel driving method in which a reset step and an address step are sequentially executed in the first subfield and second subfield of each field. A microemission step is executed in the first subfield for generating a microemission discharge between ones of the row electrodes and the column electrodes in display cells in the ON mode by applying a voltage for using the ones of the row electrodes as the anode and the column electrodes as the cathode, between the electrodes immediately after the address step. Moreover, in the microemission step, a potential lower than the voltage generated when applying a sustain pulse is respectively applied to the ones and the others of the row electrodes while applying a voltage as described above between the ones of the row electrodes and the column electrodes.
