A device for operating a plasma display panel (PDP) having sustain electrode lines, upper and lower address electrode lines, and a plurality of successive upper scan electrode lines and a plurality of successive lower scan electrode lines, comprising:
- a first Y operating part for providing a scan pulse to the upper scan electrode lines, each of the successive upper scan electrode lines being provided with a first scan pulse in a first sequence, the first sequence being changed at every new frame;
- a second Y operating part for providing a scan pulse to the lower scan electrode lines, each of the successive lower electrode lines being provided with a second scan pulse in a second sequence, the second sequence being changed at every new frame;
- 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, wherein the first and second sequences are changed at every new frame so that sequences of the first and second scan pulses applied in one sub-field of one frame are different from sequences of the first and second scan pulses applied in a same number sub-field in a succeeding frame.
A method for operating a plasma display panel having sustain electrode lines, upper and lower address electrode lines, and a plurality of successive upper scan electrode lines and a plurality of successive lower scan electrode lines, comprising:
- (a) discharging all cells on a panel for resetting the panel;
- (b) scanning each of the successive upper scan electrode lines in a first scan direction and scanning each of the successive lower scan electrode lines in a second scan direction opposite to the first scan direction;
- (c) applying a first sustain pulse to the successive 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 each of the successive upper scan electrode lines in the second scan direction and scanning each of the successive lower scan electrode lines in the first scan direction;
- and
- (f) applying a third sustain pulse to the successive upper and lower scan electrode lines and applying a fourth sustain pulse to the sustain electrode lines, wherein the scan directions of the upper and lower electrodes are changed at every new frame, wherein the scanning in (b) and (e) is performed so that the upper and lower scan electrode lines are scanned in one sub-field of one frame in a sequence different from scanning of the upper and lower scan electrode lines in a same number sub-field in a succeeding frame.
A device for operating a plasma display panel (PDP) having sustain electrode lines, address electrode lines, and a plurality of successive scan electrode lines, comprising:
- a Y operating part for providing a scan pulse to the scan electrode lines, each of the successive scan electrode lines being provided with the scan pulse in a sequence, the sequence being changed at every new frame;
- a Z operating part for operating the sustain electrode lines;
- and
- an X operating part for operating the address electrode lines, wherein a sequence of scan pulses applied to the successive scan electrode lines in one sub-field of one frame is different from a sequence of scan pulses applied to the successive scan electrode lines in a same number sub-field in a succeeding frame.
A method of operating a plasma display panel having sustain electrode lines, address electrode lines, and a plurality of scan electrode lines, comprising:
- (a) applying a first scan pulse to each of the successive scan electrode lines sequentially in a first sequence;
- and
- (b) applying a second scan pulse to each of the successive scan electrode lines sequentially in a second sequence opposite to the first sequence, wherein the first sequence is alternated with the second sequence at every new frame so that the first scan pulse is applied in a sequence in one sub-field of one frame different from a sequence in which the second scan pulse is applied in a same number sub-field in a succeeding frame.
