Plasma display apparatus and plasma display apparatus driving method

Abstract

The invention relates to a plasma display apparatus and plasma display apparatus driving method. A scan electrode driving circuit applies a first ramp waveform, which rises from a first potential (Vi1) to a second potential (Vi2), to a plurality of scan electrodes (SC) during the former half of an initializing interval of at least one of a plurality of subfields. The scan electrode driving circuit applies a second ramp waveform, which falls from a third potential (Vi3) to a fourth potential (Vi4), to the plurality of scan electrodes (SC) during the latter half interval following the former half interval. A sustain electrode driving circuit applies a third ramp waveform, which rises from a fifth potential (ground potential) to a sixth potential (Vi5), to a plurality of sustain electrodes (SU) during an interval within and shorter than the former half interval. The sustain electrode driving circuit applies a fourth ramp waveform, which falls from a seventh potential (Ve) to an eighth potential (Vi6), to the plurality of sustain electrodes (SC) during an interval within and shorter than the latter half interval.

Description

technical field [0001] The present invention relates to a plasma display device and a driving method of a plasma display panel. Background technique [0002] In an AC surface discharge type panel typified by a plasma display panel (hereinafter simply referred to as a panel), a plurality of discharge cells are formed between a front plate and a rear plate that are oppositely arranged. [0003] The front plate includes a front glass substrate, a display electrode consisting of a pair of scan electrodes and sustain electrodes, a dielectric layer and a protective layer. A plurality of display electrodes are formed on the front glass substrate in parallel to each other. A dielectric layer and a protective layer are formed on the front glass substrate to cover these display electrodes. [0004] The rear plate includes a rear glass substrate, data electrodes, dielectric layers, barrier ribs and phosphor layers. A plurality of data electrodes are formed on the rear glass substrat...

Problems solved by technology

[0021] However, in this case, since the wall charges stored in the sustain electrodes decrease, the write charges in the write period following the setup period become unstable.
