Driving method for plasma display panel, and plasma display device

Abstract

Provided is a driving method for a plasma display panel, and a plasma display device, wherein maintaining picture quality, improving driving margin, and reducing power consumption can be achieved, even when applied to an ultra high-definition panel. The driving method for a plasma display panel divides multiple displaying-electrode pairs into multiple displaying-electrode pair groups; divides a field period using multiple subfields, which have writing periods within which write-processing that makes writing-discharges be generated on the discharge-cells that are to emit light, and maintaining periods within which first and second maintaining pulses are provided to scanning electrodes and maintaining electrodes, so as not to have the writing periods for each of the displaying-electrode pair groups overlap, for each of the displaying-electrode pair groups. The aforementioned subfields have the periods of the first and second maintaining pulses to be longer than 5.5 [mu]s, within a range in which the period of time of the maintaining period does not exceed Tw*(N-1) / N, wherein the number of all the displaying-electrode pair groups is assumed to be N, and the time necessary for performing write-processing to the discharge-cells that correspond to all the displaying-electrode pairs is assumed to be Tw.

Description

technical field [0001] The present invention relates to a driving method of a plasma display panel and a plasma display device as a display device using the plasma display panel. Background technique [0002] Currently, among display devices using a plasma display panel (hereinafter, abbreviated as "PDP"), an AC surface discharge type plasma display device is representative. In an AC surface discharge type PDP, a plurality of discharge cells are formed by arranging the front substrate and the rear substrate to face each other. Hereinafter, the structure of an AC surface discharge type PDP will be described. [0003] General PDP structure [0004] On the substrate, a plurality of pairs of display electrodes composed of scan electrodes and sustain electrodes are formed in parallel with each other. In addition, a dielectric layer and a protective layer are laminated and formed on the front substrate so as to cover the display electrode pairs. A plurality of data electrodes ...

AI Technical Summary

Problems solved by technology

[0011] However, in the ADS method, since the sustain period is set in the period excluding the write period, if the period of the sustain pulse is lengthened, a sufficient number of subfields and a sufficient number of sustain pulses for ensuring image quality cannot be secured.
