  • Patent number: 7948181
    Abstract: A plasma display panel includes a front substrate having a first color, a rear substrate facing the front substrate, barrier ribs disposed between the front and rear substrates and defining discharge cells, the barrier ribs having a second color, phosphor layers disposed in the discharge cells, display electrodes arranged on the front substrate and extending in a first direction, the discharge electrodes corresponding to the discharge cells, a dielectric layer disposed on the front substrate and covering the display electrodes, the dielectric layer having a third color, address electrodes arranged on the rear substrate and extending in a second direction crossing the first direction, the address electrodes corresponding to the discharge cells, and a filter disposed on the front substrate and having a fourth color. The first through fourth colors realize a subtractive color mixture through a complementary coloring with each other.

  • Patent number: 7525250
    Abstract: A plasma display panel has an improved display electrode, thereby enhancing emission luminance. The plasma display panel includes a front substrate and a rear substrate that face each other and between which a space is formed, barrier ribs that define a plurality of discharge cells in the space between the front substrate and the rear substrate, address electrodes that extend in a first direction to intersect the discharge cells, phosphor layers that are respectively formed within the discharge cells, and first electrodes and second electrodes having linear portions that are formed in a second direction to intersect the first direction and protruded portions that extend in the first direction from the linear portions and face each other in the second direction within the discharge cells so as to form discharge gaps, respectively.
