Abstract

A plasma display includes address electrodes for scanning and addressing display cells, and scan electrodes for establishing an address discharge between the address electrodes and the scan electrodes by addressing. The display also includes common electrodes for establishing a sustain discharge between the scan electrodes and the common electrodes to display an image at the display cells, and a scan driver for supplying a voltage to the scan electrodes so as to scan display cells upon addressing during divided periods. Upon addressing, the scan driver varies the potential of a scan electrode adjacent to the scan electrode that corresponds to the addressed address electrode.

Claims

1. A plasma display comprising:

a plurality of scan electrodes;

a plurality of address electrodes for establishing an address discharge between said address electrode and said scan electrode by addressing;

a plurality of common electrodes for establishing a sustain discharge between said scan electrode and said common electrode to display an image at display cells; and

a scan driver for supplying a voltage to said scan electrode so as to scan the plurality of the scan electrodes upon addressing, said scan driver varying a potential of a scan electrode adjacent to the scan electrode that to be scanned.

2. The display according to claim 1, wherein said scan driver varies a potential of both scan electrodes adjacent to said scan electrode that to be scanned.

3. The display according to claim 1, wherein said scan driver varies a potential of the scan electrode adjacent to the common electrode for establishing a sustain discharge with said scan electrode that to be scanned.

4. The display according to claim 1, wherein said scan driver varies the potential of said scan electrode adjacent to said scan electrode that to be scanned to the ground potential upon addressing.

5. The display according to claim 4, wherein said scan driver varies the potential of said scan electrode adjacent to said scan electrode that to be scanned from a positive potential to said ground potential upon addressing.

6. The display according to claim 5, wherein said scan driver adjusts the potential of the scan electrode that to be scanned to a negative potential upon addressing.

7. The display according to claim 3, wherein said scan driver adjusts the potential of said scan electrode adjacent to said scan electrode that to be scanned to said ground potential upon addressing.

8. The display according to claim 7, wherein said scan driver varies the potential of said scan electrode adjacent to said scan electrode that to be scanned from a positive potential to said ground potential upon addressing.

9. The display according to claim 8, wherein said scan driver adjusts a scan electrode that to be scanned to a negative potential upon addressing.

10. The display according to claim 9, further comprising a common electrode driver for adjusting the potential of the common electrode to a positive potential, said common electrode serving to establish said sustain discharge with the scan electrode that to be scanned upon addressing.
