Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surface discharge type color plasma display, and more particularly to a surface discharge type color plasma display forming a large screen.

[0002]

2. Description of the Related Art FIG. 5 is a schematic view showing a conventional surface discharge type plasma display panel. The surface discharge type plasma display panel is composed of a discharge cell filled with discharge gas and three electrodes of a common electrode, a scan electrode and a data electrode.
The common electrode and the scan electrode are arranged in series on the same plane between adjacent discharge cells that are parallel to each other. On the other hand, the data electrodes are arranged in series on the same plane between adjacent discharge cells in the direction orthogonal to these.

With the above structure, when a voltage is applied between the scan electrode and the data electrode, a discharge is generated (writing discharge), and wall charges are accumulated on the inner wall of the discharge cell.
The discharge between the common electrodes is likely to occur. After writing discharge is performed on all the discharge cells to be lit by sequential scanning, when an AC voltage is applied between the scan electrodes and the common electrode, only the discharge cells that have been written discharge are lit and display is performed.

[0004]

In the above-mentioned conventional surface discharge type color plasma display panel, since the display surface is constructed on one substrate panel, a display screen exceeding the substrate size limit cannot be realized, and a large display screen is required. There is a problem that it is difficult to configure the display screen.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings.

1 and 2 are schematic diagrams showing a first embodiment of a surface discharge type color plasma display of the present invention. FIG. 1 shows a first embodiment of the present invention using three panels, and FIG. 2 shows the details of one panel. In this embodiment, as shown in FIG. 1, three plasma display panels having a common electrode, 20 cells in the scanning electrode direction, and 20 cells in the data electrode direction are prepared, and common electrode terminals of these three panels and scanning are performed. The electrode terminals were connected in series. One end of the common electrode terminal was bundled.

In the above structure, 20 scan electrodes and 60 data electrodes are sequentially scanned to perform write discharge in discharge cells to be lit, and then an AC voltage is applied between the scan electrodes and the common electrode. However, only the discharge cells that have undergone the writing discharge are lit up for display.

As described above, even when a plurality of independent panels are connected in series in the scanning electrode and common electrode directions, it is possible to perform lighting display similarly to a single panel. In this case, the same operation was performed even if the intermediate panel was removed and the two panels were connected in series.

Next, a second embodiment of the present invention will be described.

FIG. 3 is a schematic view showing a second embodiment of the surface discharge type color plasma display panel of the present invention. In this embodiment, three plasma display panels each having 20 cells in the common / scan electrode direction and 20 cells in the data electrode direction are prepared in the same manner as in the first embodiment.
The data electrode terminals of these three panels were connected in series. One end of the common electrode terminal was bundled.

In the above structure, 60 scan electrodes and 20 data electrodes are sequentially scanned to perform write discharge on the discharge cells to be lit, and then an AC voltage is applied between the scan electrodes and the common electrode. Only the discharge cells that have been subjected to the writing discharge are lit and a display is performed.

As described above, even when a plurality of independent panels are connected in series in the data electrode direction, it is possible to perform lighting display as in the case of a single panel. Also in this case, similarly to the first embodiment, the same operation was performed even if the intermediate panel was removed and the two panels were connected in series.

Next, a third embodiment of the present invention will be described.

FIG. 4 is a schematic view showing a third embodiment of the surface discharge type color display panel of the present invention. In the present embodiment, similar to the second embodiment described above, three plasma display panels having 20 cells in the common / scan electrode direction and 20 cells in the data electrode direction are prepared, and the data electrodes of these three panels are formed. The terminals were connected in parallel. One end of the common electrode terminal was bundled.

In the above structure, 60 scan electrodes and 20 data electrodes are sequentially scanned to perform write discharge in discharge cells to be lit, and then an AC voltage is applied between the scan electrodes and the common electrode. Only the discharge cells that have been subjected to the writing discharge are lit and a display is performed.

As described above, even when a plurality of independent panels are connected in parallel in the data electrode direction, the lighting display is possible as in the case of a single panel. In this case as well, similar to the first embodiment, the same operation was performed even if the intermediate panel was removed and the two panels were connected in parallel.

The above three embodiments have been shown, but these are only examples, and it is not necessary to connect a plurality of panels in series or in parallel in both directions of the scanning / common electrode and the data electrode as required. It is self-evident because it can be realized as an independent event as shown in the embodiment. As a result, a larger screen can be realized.

[0023]

As described above, a large screen can be obtained by connecting a plurality of independent panels in series or in parallel in the scanning electrode and common electrode directions as needed, and in this case also, as in the case of a single panel. An effect that it is possible to perform lighting display is provided.
