Abstract:
A plasma display panel includes a front substrate, a back substrate facing the front substrate, and a plurality of discharge cells between the front substrate and the back substrate. Pairs of discharge electrodes oppose each other in a discharge cell to make a plasma discharge occur in the discharge cell, dielectric layers cover each pair of discharge electrodes, and a thickness of the dielectric layers covering the pairs of discharge electrodes is not uniform.

A plurality of display electrodes are formed extending on the first substrate, and a plurality of address electrodes are formed extending on the second substrate and cross the display electrodes. Barrier ribs including a plurality of barrier rib members are positioned between the first substrate and the second substrate, and form a plurality of discharge cells and non-discharge regions. A phosphor is formed inside each of the discharge cells. Each of the non-discharge regions includes one of exposure regions where a part of one of the display electrodes is exposed. The exposure regions are placed alternately in an extending direction of the display electrodes.

Abstract:
A plasma display panel includes a substrate that includes a first and second substrate disposed facing each other, a plurality of discharge electrodes disposed along a circumference of a discharge cell formed between the first and second substrate, a dielectric wall that buries the discharge electrodes, and a secondary electron emission amplifying unit that emits the secondary electrons into the discharge space and is formed at least on a portion of a surface that contacts plasma generated in the discharge space during a discharge. The discharge voltage can be reduced due to an increase in the emission of the secondary electrons.
Abstract:
A plasma display panel comprising a transparent front substrate, a rear substrate disposed parallel to the front substrate, upper partition walls disposed between the front substrate and the rear substrate and demarcating light-emitting cells in a lattice pattern arranged in a first direction, an upper electrode and a lower electrode disposed in the upper partition walls around the light-emitting cells and extending in the first direction, lower partition walls disposed between the upper partition walls and the rear substrate, and an address electrode extending in a direction intersecting the upper electrode and the lower electrode.
Abstract:
A plasma display panel includes first and second substrates provided opposing one another with a predetermined gap therebetween. Address electrodes are formed on the first substrate. Barrier ribs defining discharge cells are mounted in a display region between the substrates. Further, discharge sustain electrodes are formed on the second substrate substantially perpendicular to the address electrodes. The electrodes are formed into groups of a predetermined number, and the electrodes include effective segments positioned in the display region, terminal segments positioned in a terminal region outside the display region and having a smaller pitch than that of the effective segments, and intermediate segments interconnecting these segments. In at least one group, lengths of elements of the terminal segments increasingly decrease as a distance from a center of the group is increased.
Abstract:
A plasma display panel where the address electrodes are designed to have perforated portions in the vicinity of display electrodes to prevent the build up of unwanted wall charges in the vicinity of the display electrodes to thus prevent mis-discharge in the plasma display panel. The perforations can be quadrilateral in shape, and can be made to different sizes depending on the color of the phosphor in the vicinity of the perforation. As a result, drive voltage margin quality between the different colors can be improved to produce a more reliable display.
Abstract:
Disclosed is a PDP driving method and a plasma display device for providing stable discharge characteristics by varying gradients of PDP driving waveforms according to the external temperature of the PDP. A protection film of MgO reduces the secondary emission coefficient as the temperature is reduced. In order to compensate for the reduction, the external temperature is measured by an external temperature sensor, and the gradients in a falling period and/or the rising period during a reset period of a driving voltage waveform are modified according to the measured external temperature. In detail, the gradients in the falling period and/or the rising period of the reset period are varied to be less steep when the measured temperature is reduced to below a predetermined level such as freezing or −10 degrees C.
