Problems solved by technology
[0008] However, if the discharge cells are miniaturized along with the high definition of the panel, or the partial voltage of xenon is increased to increase the luminance of the panel, the write discharge becomes unstable, and no write occurs in the discharge cells that need to be displayed. Discharge, image display quality deteriorates, or the necessary voltage for generating write discharge becomes higher, etc.
In addition, if the voltage applied to the discharge cells during writing is increased in order to stably generate address discharge, the discharge cells not performing the address operation will be affected by the adjacent discharge cells, for example, the wall charges will decrease, resulting in contact. Writes in down subdomains become unstable and other issues

In a plasma display device and a method for driving a plasma display panel, stable writing discharge is generated without increasing a voltage required for writing. The plasma display device is provided with a plasma display panel having a plurality of scanning electrodes and sustaining electrodes which configure a display electrode pair. The plasma display device is also provided with a sustaining pulse generating circuit, which has a plurality of subfields having an initializing period, a writing period and a sustaining period in one field period, and generates sustaining pulses by varying the inclination of the start up of the sustaining pulse in the sustaining period. The sustaining pulse generating circuit generates at least two kinds of sustaining pulses whose start up of one sustaining pulse is sharper than that of the other sustaining pulse in at least one subfield sustaining period among the subfields. The sustaining pulse generating circuit applies the sustaining pulses having sharp start up to one electrode of the display electrode pair consecutively two or more times at the end of the sustaining period.
Description
technical field [0001] The present invention relates to a wall-mounted television or a plasma display device used in a large monitor (monitor) and a driving method of a plasma display panel. Background technique [0002] A typical AC surface discharge panel as a plasma display panel (hereinafter simply referred to as a "panel") has a plurality of discharge cells formed between a front panel and a rear panel that are arranged to face each other. In the front panel, a plurality of display electrode pairs including a pair of scan electrodes and sustain electrodes are formed parallel to each other on the front glass substrate, and a dielectric layer and a protective layer are formed to cover these display electrode pairs. The back panel is respectively formed with a plurality of parallel data electrodes, a dielectric layer covering these data electrodes, and a plurality of partition walls parallel to the data electrodes on the rear glass substrate. On the surface and side walls ...
