摘要： In a plasma display panel, a protective layer of a front plate is formed of a base protective layer and a particle layer. The base protective layer is a thin film of metal oxide containing at least one of magnesium oxide, strontium oxide, calcium oxide, and barium oxide. The particle layer is formed in a manner that single-crystal particles of magnesium oxide having a peak of emission intensity at 200-300 nm two times or higher than another peak of emission intensity at 300-550 nm in the emission spectrum in cathode luminescence emission are stuck on the base protective layer. A panel driving circuit drives the plasma display panel with a subfield structure in which subfields are temporally disposed so that a magnitude of luminance weight has a monotonous decrease from a subfield where an all-cell initializing operation is performed to a subfield where a next all-cell initializing operation is performed.

摘要： A method of driving a plasma display panel having display electrode pairs each one of which pairs is formed of a scan electrode and a sustain electrode. A priming electrode is placed in every other spaces between the display electrode pairs and in parallel with the display electrode pairs. An addressing period includes an odd-line addressing period in which an address operation is conducted to primary discharge cells having odd-number scan electrodes, an even-line addressing period in which an address operation is conducted to primary discharge cells having even-number scan electrodes. During the respective addressing periods, scan pulse voltage Va is applied to odd-number scan electrodes or even-number scan electrodes while priming pulse voltage Vp is applied, prior to the application of the scan pulse voltage, to a priming electrode adjacent to the scan electrode to which scan pulse voltage Va is to be applied, in order to generate a priming discharge between the priming electrodes and the data electrodes.

摘要： 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.

摘要： A cable television system includes a transmitter and at least one receiver. In the transmitter, sync information is suppressed in amplitude to execute scrambling, and a sync width information signal and key data are superimposed on a television signal during a vertical blanking period. The sync width information signal has a burst form and a predetermined width, and represents whether sync information is present or absent. The key data represents contents of the scrambling. In the receiver, the sync width information signal is recovered, and a sync width information pulse corresponding to the sync width information signal is generated. A reference signal is generated on the basis of an edge of the sync width information pulse. The key data is extracted from the scrambled video information in response to the reference signal. Pseudo sync signals are generated in response to an edge of the sync width information pulse. The sync information of the scrambled video information is increased in amplitude in response to the extracted key data at timings determined by the pseudo sync signals.
