摘要： In a former half (T11) of an all-cell reset period (T1), the potential of a scan electrode (Scn) is raised from 0 [V] to Vp [V] at a timing t0, and thereafter maintained at the positive potential of Vp [V] to Vg [V] until a timing t3 when the former half (T11) ends. On the other hand, in the same former half (T11), a reset pulse (Pul.2), which includes a negative ramp waveform portion from 0 [V] to a potential of Vr [V], is applied to a sustain electrode (Sus). A time period (t1−t0) of the negative ramp waveform portion of the pulse (Pul.2) is set longer than a time period required for the potential change of a pulse (Pul.1) from P1 to P2.

摘要： The present invention provides a plasma display panel and a method for driving the plasma display panel each of which ensures to suppress problems associated with an erroneous discharge resulting from accidental occurrence of a strong discharge in a reset period as well as with an address discharge delay. The problems are suppressed without applying an auxiliary erase pulse after the reset period ends. As a result, image display is provided with no flickering and good quality. The reset period includes a first step of applying a voltage having an ascending ramp waveform and a second step of applying a voltage having a descending ramp waveform. Between the first and second steps, a potential change waveform having a rise or fall (voltage change pulse) is applied at least to scan electrodes, sustain electrodes, or address electrodes.

摘要： Provided are a PDP device and a drive method thereof which restrict the generation of an erroneous discharge in the all-cell reset period and to restrict the appearance of flickers in the areas with low grayscale levels even if some areas have a lower firing voltage than the other areas due to variation of a property in the panel surfaces or due to a long-term driving, or even if the voltage applied to the address electrode is increased with the pursuit of high definition.The pulse Pul.3 is applied to address electrodes Dat at timing t0 prior to timing t1 when the potential of the scan electrodes Scn is increased to Vq(V). In this drive method, voltage Vx(V) is applied to address electrodes Dat so that there is no potential difference between the scan electrodes Scn and the sustain electrodes Sus at timing t0 when discharge Dis.3 is generated. Accordingly, the discharge Dis.3, which is generated between the scan electrodes Scn and the sustain electrodes Sus due to reduction in the firing voltage, does not become a trigger for extending to the scan electrodes Scn to generate an erroneous discharge.

摘要翻译： 本发明提供一种限制全电池复位期间发生错误放电的PDP装置及其驱动方法，即使某些区域的点火电压低于低电平，也限制了灰度级低的区域的闪烁状态 由于面板表面的特性变化或由于长期驱动而导致的其它区域，或者即使施加到寻址电极的电压随着追求高清晰度而增加。 当扫描电极Scn的电位增加到Vq（V）时，在定时t1之前的定时t0将脉冲Pul.3施加到寻址电极Dat。 在这种驱动方法中，电压Vx（V）被施加到寻址电极Dat，使得当在产生放电Dis.3时在定时t0处扫描电极Scn和维持电极Sus之间没有电位差。 因此，由于降低烧制电压而在扫描电极Scn和维持电极Sus之间产生的放电Dis.3不会成为延伸到扫描电极Scn以产生错误放电的触发器。

摘要： In a driving method of a panel, one field period is formed by arranging a plurality of subfields that have an address period for selectively causing address discharge in a discharge cell, and a sustain period for causing as many sustain discharges as the number corresponding to luminance weight in the discharge cell. One field period is formed by arranging a plurality of subfield groups having a plurality of subfields whose luminance weights monotonically increase. In the discharge cell for causing address discharge in a certain subfield other than the head subfield in each subfield group, address discharge is caused even in the head subfield.

摘要： An unnecessary discharge caused in the discharge cells in an initializing operation is prevented. This reduces the luminance of black level in a display image and stabilizes the address discharge at the same time, thus enhancing the image display quality. A plasma display panel that has a plurality of discharge cells having data electrodes and display electrode pairs, each formed of a scan electrode and a sustain electrode, is driven for gradation display such that a plurality of subfields is set in one field and each of the subfields has an initializing period, an address period, and a sustain period. For the above purpose, in the driving method for the plasma display panel, the following operations are performed. In the address period of a predetermined subfield, after the application of a scan pulse to all the scan electrodes is completed, a ramp voltage gently falling from a first voltage is applied to the sustain electrodes. In the period during which the falling ramp voltage is applied to the sustain electrodes, a second voltage is applied to the data electrodes.
