Abstract: Set-up, write, sustain and erase pulses are variously applied to a plasma display panel using a staircase waveform in which the rising or falling portion is in at least two steps. These staircase waveforms can be realized by adding at least two pulses. Use of such waveforms for the set-up, write and erase pulses improves contrast, and use for the sustain pulses reduces screen flicker and improves luminous efficiency. This is of particular use in driving high definition plasma display panels to achieve high image quality and high luminance.

Abstract: A plasma display panel with a drive circuit that divides a field into a plurality of sub-fields with each sub-field including a write period, a discharge sustain period and an erase period. In the discharge sustain period at least one of a plurality of pulses applied in a later part of the discharge sustain period has a larger pulse width than a pulse applied in an earlier part of the discharge sustain period and in the erase period, a narrow pulse is applied to a pair of electrodes extending across each of a plurality of discharge cells. The narrow pulse has a pulse height lower than a discharge firing voltage of the plurality of discharge cells and a smaller pulse width than the pulses applied in the discharge sustain period.

Abstract: A plasma display device that enables a stable address operation even in a high-speed drive so as to display an image of high definition and high quality. A PDP having discharge cells each provided with a scanning electrode and a sustaining electrode is driven by a method for displaying a frame of an image by repeating an address period, a discharge sustaining period, and a discharge suspend period. At least one initialization period that succeeds a discharge suspend period and in which the state of the wall charge in each discharge cell is initialized is provided. In the discharge suspend period, a voltage is applied between the scanning electrode and the sustaining electrode so that a wall voltage may be generated at which the polarity at the scanning electrode with respect to the sustaining electrode is the same as that of the initializing pulse applied to the scanning electrode in the initialization period.

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 ?s.

Abstract: A method of driving a plasma display panel including a plurality of priming electrodes. The pulse width of scan pulses applied to some of a plurality of scan electrodes in which writing is performed and priming discharge is caused with the scanning of the scan electrodes is larger than the pulse width of scan pulses applied to the other scan electrodes in which writing is performed but no priming discharge is caused with the scanning of the scan electrodes.

Abstract: It is an object of the present invention to provide a plasma display apparatus in which reliable erase discharge is performed and an erroneous discharge is suppressed, even when a discharge sustain period is shortened so as to realize a PDP having high definition. The above object is achieved in the following manner. In the discharge sustain period, a pulse applied in the later part of the discharge sustain period has a larger pulse width than a pulse applied in the earlier part of the discharge period, except for an initial pulse in the discharge sustain period. In addition, a called narrow pulse is applied in an erase period to perform an erase discharge. According to this method, wall voltages in discharge cells at the end of the discharge sustain period are raised to a higher level than in the related art. As a result, reliable erase discharge is performed, and an erroneous discharge is suppressed.

Abstract: 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?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?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.

Abstract: It is the object of the invention to provide a PDP apparatus and a driving method that can apply pulses at high speeds and can display high-definition, high-quality images by allowing discharge cells to emit light with high luminance and high efficiency. To achieve the object, the pulse has (i) a first waveform portion where a first voltage, an absolute value of which is no smaller than a discharge start voltage, is applied and (ii) a second waveform portion where a second voltage, an absolute value of which is greater than the absolute value of the first voltage, is applied, the second waveform portion following the first waveform portion, and the second waveform portion starts before a discharge delay time elapses from a start of the first waveform portion.

Abstract: A plasma display apparatus has a waveform of a driving voltage supplied from a driver. The waveform has a sustaining period when a sustaining pulse is alternately applied to scanning electrodes and sustain electrodes for keeping discharge. Besides, the waveform has an erasing period when a ramp voltage pulse whose polarity differs from that of a sustaining pulse is applied to an electrode, which differs from an electrode where a last pulse of the sustaining pulse is applied. As a result, false discharge is prevented, and a stable image can be displayed.

Abstract: The invention is a plasma display panel capable of stabilizing the addressing characteristics. A barrier rib is formed by longitudinal barrier ribs portion orthogonal to the scan electrodes and sustain electrodes on the front substrate, and side barrier rib portions crossing with these longitudinal barrier rib portions, to form cell spaces and form interstice portions between the cell spaces, and priming electrodes for producing a discharge between the front substrate and the rear substrate within the interstice portions are formed. Stable priming discharge is produced with certainty by the scan electrode and the priming electrode, hence decreasing the discharge time lag at the time of addressing and stabilizing the addressing characteristics.

Abstract: A plasma display panel (PDP) drive method eliminates crosstalk and allows for high quality image display by preventing erroneous discharge from occurring in an address period. The method includes an address step of writing data by applying an address pulse to a third electrode and a scan pulse Pas1 sequentially to first electrodes, and a sustain step of sustaining an illumination by applying sustain pulses between first and second electrodes after completion of the address step. Furthermore, in the address step, a scan pulse Pas2 of opposite polarity to scan pulse Pas1 is applied to a second electrode in a pair with a first electrode in a selected line (i.e. a line in which scan pulse Pas1 is being applied).

Abstract: Barrier ribs 18 formed on a back substrate PA2 are brought into contact with a bonding paste layer 40 having an even surface, applying a bonding agent Bd evenly to the tops of the barrier ribs. Furthermore, a gas discharge panel having a structure in which discharge mainly occurs at locations distanced from parts of the panel connected using the bonding agent Bd is realized.
