Claims23
A device for operating a plasma display panel (PDP) having sustain electrode lines, address electrode lines, and scan electrode lines, comprising:
- a Y operating part for providing a scan pulse to the scan electrode lines in a sequence, the sequence being changed at fixed intervals;
- a Z operating part for operating the sustain electrode lines;
- and
- an X operating part for operating the address electrode lines.
A device for operating a plasma display panel (PDP) having sustain electrode lines, upper and lower address electrode lines, and upper and lower scan electrode lines, comprising:
- a first Y operating part for providing a scan pulse to the upper scan electrode lines in a sequence, the sequence being changed at fixed intervals;
- a second Y operating part for providing a scan pulse to the lower scan electrode lines in a sequence, the sequence being changed at fixed intervals;
- a Z operating part for operating the sustain electrode lines;
- a first X operating part for operating the upper address electrode lines;
- and
- a second X operating part for operating the lower address electrode lines.
A method for operating a plasma display panel having sustain electrode lines, address electrode lines, and scan electrode lines, comprising the steps of:
- (a) applying a scan pulse to the scan electrode lines progressively;
- and
- (b) applying a scan pulse to the scan electrode lines reverse progressively.
A method for operating a plasma display panel having sustain electrode lines, upper and lower address electrode lines, and upper and lower scan electrode lines, comprising the steps of:
- (a) discharging all cells on a panel for resetting the panel;
- (b) scanning the upper scan electrode lines in a first scan direction and scanning the lower scan electrode lines in a second scan direction opposite to the first second direction;
- (c) applying a first sustain pulse to the upper and lower scan electrode lines and a second sustain pulse to the sustain electrode lines;
- (d) discharging all cells on the panel for resetting the panel;
- (e) scanning the upper scan electrode lines in the first scan direction and scanning the lower scan electrode lines in the first scan direction;
- and
- (f) applying a first sustain pulse to the upper and lower scan electrode lines and applying a second sustain pulse to the sustain electrode lines.
