  • Patent number: 7663317
    Abstract: A plasma display panel includes first and second substrates having a predetermined gap therebetween. Barriers are disposed between the first and second substrates to partition discharge cells and fluorescent layers are formed in the discharge cells. Address electrodes corresponding to the discharge cells extend in a first direction, and pairs of first and second electrodes extend in a second direction to cross the first direction. The address electrodes are on one of the substrates to correspond to the discharge cells. A dielectric layer covers the first and second electrodes, wherein the dielectric layer is colored with a first color, the barriers are colored with a second color having a subtractive mixture relation with the first color, and wherein the fluorescent layers include first fluorescent layers on the barriers and the discharge cells, and second fluorescent layers on the first fluorescent layers in the second color.

  • Publication number: 20080136327
    Abstract: A plasma display panel (PDP) is capable of effectively reducing noise occurring during operation of the panel by improving the construction of a dummy partition included in a partition, and reduces a rate of defects in the partition due to a uniform coating of a fluorescent paste. The PDP includes: a front glass including sustain electrodes and dielectric layers; a rear glass including address electrodes and dielectric layers; a partition between the front and rear glasses and including a main partition and a dummy partition, each having discharge spaces of respective sizes; and a fluorescent layer coated on the respective discharge spaces.

  • Patent number: 7375468
    Abstract: A plasma display panel comprising a first panel having a plurality of discharge sustaining electrode pairs, and a second panel having a plurality of address electrodes and facing the first panel. A discharge sustaining electrode pair includes a scan electrode and a sustain electrode having discharge surfaces facing each other, and the scan electrode is closer to the address electrode than the sustain electrode. The plasma display panel requires a reduced address voltage and discharge voltage.

  • Patent number: 7030560
    Abstract: A plasma display panel (PDP) includes a first substrate and a second substrate opposing one another with a predetermined gap therebetween. The first substrate and the second substrate are substantially rectangular in shape with long side edges and short side edges, and are interconnected by frit deposited between the first substrate and the second substrate. The substrates have a predetermined discharge region and predetermined non-discharge regions that surround the discharge region. The PDP also includes barrier ribs mounted between the first substrate and the second substrate. The barrier ribs are mounted at least partly on the discharge region, and at least partly on the non-discharge regions that are adjacent to the long side edges of the substrates.
