DRIVING METHOD FOR PLASMA DISPLAY PANEL, AND PLASMA DISPLAY DEVICE

摘要

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 µs, within a range in which the period of time of the maintaining period does not exceed Tw × (N-1)/N, where 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.
