Patent ID: 7786956

Claim:
A plasma display device comprising: a plasma display panel having a plurality of scan electrodes and sustain electrodes, which are disposed parallel to each other on a front panel and configure display electrode pairs, and are electrically connected to a plurality of scan-electrode lead lines and sustain-electrode lead lines at one ends respectively, and a plurality of data electrodes that are disposed in a direction intersecting with the scan electrodes on a back panel disposed oppositely to the front panel with discharge spaces between them, and configure display cells with the display electrode pairs; a scan-electrode drive circuit connected to the scan-electrode lead lines for driving the scan electrodes; a sustain-electrode drive circuit connected to the sustain-electrode drive circuit for driving the sustain electrodes; and a data-electrode drive circuit that divides the data electrodes into a plurality of data electrode groups and drives the groups respectively; wherein the data-electrode drive circuit applies writing pulse voltage to each of the data electrode groups in order from a data electrode group nearest to the scan-electrode lead lines in a writing period; and wherein in the writing period, time between adjacent two peaks of writing discharge current flowing into the data-electrode drive circuit by applying the writing pulse voltage to each of the data electrode groups is longer than time from applying writing pulse voltage to the data electrode group nearest to the scan-electrode drive circuit to applying the writing pulse voltage to a data electrode group second-nearest to the scan-electrode drive circuit.
