Plasma display panel driving method and plasma display device

Abstract

Disclosed are a plasma display panel driving method and a plasma display device wherein stable write discharge is generated even when applied to a high-definition and large-screen plasma display panel. For this, the image display region of the plasma display panel is divided into a plurality of partial display regions, and the scanning electrodes in each of the partial display regions are divided into a first scanning electrode group including odd-numbered scanning electrodes and a second scanning electrode group including even-numbered scanning electrodes on the basis of the sequence in which the scanning electrodes are arrayed in the plasma display panel. Then, in each of the partial display regions, skip write operation is performed in a writing period, the skip write operation being sequentially applying scanning pulses to each of the scanning electrodes belonging to one of the scanning electrode groups and thereafter sequentially applying the scanning pulses to each of the scanning electrodes belonging to the other scanning electrode group. In each of the scanning electrode groups, the scanning electrodes to be subjected to the first to predetermined-numbered application of the scanning pulses are subjected to the application of the scanning pulses wherein a pulse period is set to be longer than that of the scanning pulses to be applied to the other scanning electrodes.

Description

technical field [0001] The present invention relates to a driving method of a plasma display panel used in a wall-mounted television or a large monitor and a plasma display device utilizing the driving method. 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 substrate and a rear substrate that are arranged to face each other. In the front substrate, a plurality of pairs of display electrodes consisting of a pair of scan electrodes and a pair of sustain electrodes are formed parallel to each other on the glass substrate on the front side. Furthermore, a dielectric layer and a protective layer are formed so as to cover these display electrode pairs. [0003] In the rear substrate, a plurality of parallel data electrodes are formed on a glass substrate on the rear side, a dielectric layer is formed to cover these data electrodes, a...

Problems solved by technology

In addition, since the discharge cells are miniaturized in a high-precision panel, the difference in influence between when an address discharge occurs and when an address discharge does not occur in adjacent discharge cells tends to become larger.

[0014] In addition, since the number of scan electrodes increases in a large-screen panel with high precision, the time taken for the writing period becomes longer.

Furthermore, when the time from initializing discharge to address discharge becomes longer, the wall charges required for address operation decrease, and address discharge tends to become unstable.
