Abstract
A plasma display device is provided. The plasma display device may include a plasma display panel (PDP), an upper substrate and a lower substrate, a plurality of scan electrodes and a plurality of sustain electrodes on the upper substrate, a plurality of first barrier ribs on the lower substrate in parallel with the scan electrodes and the sustain electrodes, a plurality of second barrier ribs on the lower substrate, that intersect the first barrier ribs, and are higher than the first barrier ribs, and a plurality of auxiliary electrodes on the upper substrate and overlap the first barrier ribs. Accordingly, the amount of invalid power of a PDP may be reduced by preventing crosstalk from occurring between a pair of sustain electrodes with a barrier rib interposed therebetween.
Claims20
A plasma display device comprising:
- a plasma display panel (PDP);
- an upper substrate and a lower substrate that face each other;
- a plurality of scan electrodes and a plurality of sustain electrodes that are disposed on the upper substrate;
- a plurality of first barrier ribs that are disposed on the lower substrate in parallel with the scan electrodes and the sustain electrodes;
- a plurality of second barrier ribs that are disposed on the lower substrate, that intersect the first barrier ribs, and are higher than the first barrier ribs;
- and
- a plurality of auxiliary electrodes that are disposed on the upper substrate and overlap the first barrier ribs, wherein the auxiliary electrodes are spaced apart from the respective scan electrodes and from the respective sustain electrodes.
A plasma display device comprising:
- a plasma display panel (PDP);
- an upper substrate;
- a lower substrate;
- a plurality of scan electrodes and a plurality of sustain electrodes provided on the upper substrate;
- a plurality of first barrier ribs provided on the lower substrate in parallel with the scan electrodes and the sustain electrodes;
- a plurality of second barrier ribs on the lower substrate that intersect the first barrier ribs, wherein a height of the plurality of second barrier ribs is greater than a height of the plurality of first barrier ribs;
- and
- a plurality of auxiliary electrodes that overlap the first barrier ribs, wherein the auxiliary electrodes are spaced on the upper substrate from the respective scan electrodes and are spaced on the upper substrate from the respective sustain electrodes.
