Plasma display panel (PDP)

Abstract

A Plasma Display Panel (PDP) has a reduced power consumption by forming transparent electrodes of the PDP so that the brightness of the PDP can be gradually reduced from a central region towards outer regions of the PDP. The PDP includes: a first substrate and a second substrate facing each other; a plurality of barrier ribs arranged between the first and second substrates to define a plurality of discharge cells; a plurality of sustain electrode pairs each having: a common electrode including a first bus electrode extending across the first substrate and a first transparent electrode bonded to the first bus electrode, each of the plurality of sustain electrode pairs is separated corresponding to each of the discharge cells, and has different areas in each discharge cell; and a scanning electrode including a second bus electrode extending across the first substrate and separated from the first bus electrode and a second transparent electrode bonded to the second bus electrode, the scanning electrode is separated corresponding to each of the discharge cells, and has different areas in each discharge cell; the areas of the first and second transparent electrodes are gradually reduced outwards from the center of the PDP; a first dielectric layer covering the sustain electrode pairs; a plurality of phosphor layers arranged within the discharge cells; and a discharge gas contained within each of the discharge cells.
