Abstract
The present invention relates to a plasma display apparatus and driving method thereof, and more particularly, to a plasma display apparatus that generates a sustain pulse, and driving method thereof. The present invention controls a rising time of a sustain pulse applied to electrodes according to a load of a video signal, such as an APL value, a display area or the number of a sustain pulse. The plasma display apparatus and the driving method of the present invention controls a rising time of a sustain pulse according to a load. Therefore, a bright afterimage can be prohibited and the picture quality can be improved.
Claims18
A plasma display apparatus, comprising:
- a load calculator receiving a video signal and calculates a load of the video signal;
- and
- a rising time controller controlling a rising time of a sustain pulse according to the load.
A driving method of a plasma display apparatus, comprising the steps of:
- receiving a video signal and calculating a load of the video signal;
- and
- deciding a rising time of a sustain pulse according to the load of the video signal.
A plasma display apparatus, comprising:
- a sub-field mapping unit receiving a video signal and calculates a sub-field corresponding to a gray level;
- a load calculator receiving information on the sub-field mapped by the sub-field mapping unit, and allots the number of a sustain pulse of each sub-field;
- and
- a rising time controller that controls a rising time of a sustain pulse allotted to at least one of a plurality of sub-fields according to the number of the sustain pulse allotted to each sub-field.
