Abstract:
Disclosed is a plasma display panel where the shape of the phosphor layer within the discharge cell is optimized to enhance the discharge stability and the luminescence efficiency. In one embodiment, the plasma display panel includes a first substrate and a second substrate facing each other, display electrodes formed on the first substrate, address electrodes formed corresponding to the display electrodes, barrier ribs arranged between the first substrate and the second substrate such that discharge cells are formed at the locations where the display electrodes and the address electrodes correspond to each other, phosphor layers formed within the discharge cells, and a porous dielectric layer formed between the phosphor layers and the second substrate.
Abstract:
A novel design for a plasma display panel where a dielectric grid structure is formed between the front and the rear substrate. Some or all of the electrodes are formed within the dielectric grid structure. The electrodes surround individual discharge cells and thus produce a more efficient discharge. A resistive element is built into the electrodes to reduce current and to reduce power consumption. The sustain discharge electrodes, made of X and Y electrodes each are made of at least two separate electrode lines, all four electrodes being formed within the dielectric grid. By such a design, power consumption is reduced and light emission efficiency is improved.
Abstract:
A plasma display panel (PDP), includes a temperature difference between a display area and a peripheral area not increasing greatly in an aging process, thus preventing a damage of the PDP due to a difference between thermal expansion rates of the display area and the peripheral area. The PDP includes a transparent front substrate; a back substrate disposed in parallel to the front substrate; light emitting cells defined by barrier ribs that are disposed between the front substrate and the back substrate; address electrodes extended throughout the light emitting cells that are disposed in a row; a back dielectric layer covering the address electrodes; sustain electrode pairs, each of which includes an X electrode and a Y electrode that are extended to cross the address electrodes and parallel to each other; a front dielectric layer covering the sustain electrode pairs; a phosphor layer disposed in the light emitting cell; and a discharge gas filled in the light emitting cell. Some of the sustain electrode pairs includes the X electrodes having short connection terminals and the Y electrodes having long connection terminals, and the other sustain electrode pairs include the X electrodes having long connection terminals and the Y electrodes having short connection terminals.

First and second substrates are provided opposing one another. Address electrodes are formed on the second substrate. Barrier ribs are mounted between the first and second substrates defining discharge cells and non-discharge regions. Phosphor layers are formed within each of the discharge cells. Discharge sustain electrodes are formed on the first substrate. The non-discharge regions are formed in areas encompassed by discharge cell abscissas and ordinates passing through centers of the discharge cells. Further, the discharge cells are formed such that ends thereof increasingly decrease in width as a distance from centers of the discharge cells is increased. The discharge sustain electrodes include bus electrodes that extend perpendicular to the address electrodes and outside areas of the discharge cells but across areas of the non-discharge regions, and protrusion electrodes formed extending from each of the bus electrodes.
Abstract:
A plasma display panel includes a first substrate, on which discharge sustain electrodes are formed, and an opposing second substrate, on which address electrodes are aligned in a first direction. Barrier ribs between the substrates define a plurality of discharge cells within which phosphor layers are formed. The display electrodes have bus electrodes, forming a corresponding pair within each of the discharge cells, and extension electrodes, extending from the bus electrodes into each of the discharge cells to form an opposing pair. A pair of the display electrodes corresponding to each of the discharge cells forms a first gap and a second gap having different distances from each other between the opposing extension electrodes, and forms a third gap between the bus electrodes. The second gap is longer than the first gap, and the third gap is longer than the second gap.
