The first object of the present invention is to provide a PDP with improved panel brightness which is achieved by improving the efficiency in conversion from discharge energy to visible rays. The second object of the present invention is to provide a PDP with improved panel life which is achieved by improving the protecting layer protecting the dielectrics glass layer. To achieve the first object, the present invention sets the amount of xenon in the discharge gas to the range of 10% by volume to less than 100% by volume, and sets the charging pressure for the discharge gas to the range of 500 to 760 Torr which is higher than conventional charging pressures. With such construction, the panel brightness increases. Also, to achieve the second object, the present invention has, on the surface of the dielectric glass layer, a protecting layer consisting of an alkaline earth oxide with (100)-face or (110)-face orientation. The protecting layer, which may be formed by using thermal Chemical Vapor Deposition (CVD) method, plasma enhanced CVD method, or a vapor deposition method with irradiation of ion or electron beam, will have a high sputtering resistance and effectively protect the dielectrics glass layer. Such a protecting layer contributes to the improvement of the panel life.

Plasma display panel and manufacturing method therefor

During each set-up period, wall charges of scan electrodes and sustain electrodes, between which sustain discharges were generated in the previous subfield, are adjusted, and parts toward the sustain electrodes of positive charges in the scan electrodes are replaced by negative charges and parts toward the scan electrodes of negative charges in the sustain electrodes are replaced by positive charges. During each address period, write pulses are applied to the scan electrodes to generate write discharges utilizing priming discharges between the scan electrodes and priming electrodes. During each sustain period, positive charges are accumulated in the entire surfaces of the scan electrodes and negative charges are accumulated in the entire surfaces of the sustain electrodes.

Plasma display apparatus and driving method thereof

A method drives a plasma display panel including priming electrodes. In the writing period of a sub-field, prior to the scanning of respective scan electrodes, priming discharge is caused between the scan electrodes and the priming electrodes. The time interval between the application of voltage to the priming electrodes for causing the priming discharge and the scanning of the corresponding scan electrodes is set within 10 &#x3bc;s.

Method of driving plasma display panel

When applying sustain pulses to each discharge cell in a gas discharge panel, a pulse of the opposite polarity is briefly applied immediately before the leading edge of each sustain pulse. Or, the absolute voltage of each sustain pulse is set higher during a certain period from the leading edge of the sustain pulse than during a period from the lapse of the certain period to the trailing edge of the sustain pulse, and a pulse of the opposite polarity is briefly applied immediately after the trailing edge of the sustain pulse. As a result, discharge delays during a discharge sustain period are suppressed to improve image quality, and reactive currents are reduced to improve luminous efficiency.

A method of driving a plasma display device that includes a plurality of scanning electrodes, a plurality of sustaining electrodes, and a plurality of data electrodes is such that, when m is any given integer, the data electrodes are applied with a negative polarity pulse when a voltage applied to the scanning electrodes gradually decreases during the initialization period, if a final pulse in a sustain period of an (m&#x2212;1)-th subfield is applied to the scanning electrodes and an m-th subfield includes an initialization period. If the final pulse in the sustain period of the (m&#x2212;1)-th subfield is applied to the sustaining electrodes and the m-th subfield includes the initialization period, the data electrodes are applied with a positive polarity pulse when a voltage applied to the scanning electrodes gradually increases during the initialization period.
