Problems solved by technology

[0009] However, in the above-mentioned display panel, adjacent discharge cells are likely to cause mutual interference, especially during the write period, there is an influence of priming (priming) generated with the write discharge of adjacent discharge cells, or There is a risk of erroneous writing or poor writing, so there is a problem that the driving voltage margin of the writing operation is narrowed

Embodiment approach 1

[0018] Hereinafter, the display panel in Embodiment 1 of the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view showing the structure of a display panel in Embodiment 1 of the present invention, and FIG. 2 is a cross-sectional view of the display panel. Glass-made front substrate 21 as a first substrate and rear substrate 31 as a second substrate are opposed to each other across a discharge space, and neon and xenon that radiate ultraviolet rays by discharge are enclosed in the discharge space.

[0019] On front substrate 21, a plurality of display electrode pairs consisting of scan electrodes 22 and sustain electrodes 23 are formed in parallel to each other. At this time, the scan electrodes 22 and the sustain electrodes 23 are alternately arranged every two like sustain electrodes 23 -scan electrodes 22 -scan electrodes 22 -sustain electrodes 23 - . . . . Scan electrode 22 and sustain electrode 23 are composed of trans...

Embodiment approach 2

[0045] The structure of the display panel according to the second embodiment of the present invention is the same as that of the first embodiment. In addition, in the driving method, there are odd-numbered row writing periods and even-numbered row writing periods as writing periods, and the case of separating them by time is the same as in the first embodiment. Embodiment 2 differs from Embodiment 1 in that there is a subfield provided for temporally separating the odd-numbered row initialization period and the even-numbered row initialization period also in the initialization period. That is, in at least one of the plurality of subfields, there is an odd row initialization period in which the initialization operation of the main discharge cells of the odd-numbered scan electrodes is performed, and an initialization operation of the main discharge cells of the even-numbered scan electrodes is performed. Set the odd row initialization period before the odd row write period, and...

Abstract

There are partitions arranged on the back substrate to distinguish each main discharge unit formed by the display electrode pair and the data electrode opposite, and at the same time to distinguish the initiation discharge unit formed between the gaps between two adjacent scan electrodes in the scan electrodes. The top is formed in contact with the front substrate. The driving method is to sequentially apply scan pulse Va to odd-numbered scan electrodes SCp during the writing period of odd-numbered rows, and apply voltage Vq for generating a priming discharge between odd-numbered sustain electrodes SUp+1 and odd-numbered scan electrodes SCp, and write to even-numbered rows. During this period, the scan pulse Va is sequentially applied to the even-numbered scan electrodes SCp+1, and the voltage Vq for generating a priming discharge with the even-numbered scan electrodes SCp+1 is applied to the odd-numbered scan electrodes SCp.

Description

technical field [0001] The present invention relates to a driving method of a plasma display panel used in a wall-mounted television, a large monitor, and the like. Background technique [0002] A plasma display panel (hereinafter abbreviated as PDP or display panel) is a display with excellent visibility featuring a large screen, thin profile, and light weight. [0003] In an AC surface discharge type display panel typical of PDPs, a plurality of discharge cells are formed between a front panel and a rear panel that are arranged to face each other. In the front panel, multiple pairs of display electrodes consisting of scan electrodes and sustain electrodes are formed parallel to each other on the front glass substrate, and an insulator layer and a protective layer are formed to cover these display electrodes. On the back panel, a plurality of parallel data electrodes, an insulator layer that can cover these electrodes, and a plurality of partition walls parallel to the dat...
