[0069] Figure 7 The electrodes of the plasma display panel according to the first embodiment of the present invention are shown. like Figure 7 As shown, in the electrode structure of the plasma display panel according to the first embodiment of the present invention, scan electrodes, sustain electrodes, and scan electrodes are sequentially formed.

[0070] Therefore, two scan electrodes and one sustain electrode form two sustain electrode pairs. For example, the second scan electrode Y 2 and the second sustain electrode Z 2 A sustain electrode pair is formed, and the third scan electrode Y 3 and the second sustain electrode Z 2 A sustain electrode pair is formed. Therefore, with the help of the second scan electrode Y 2 and the second sustain electrode Z 2 Instead, pulses are supplied to the discharge cells. With the help of the third scan electrode Y 3 and the second sustain electrode Z 2 Instead, pulses are supplied to the discharge cells.

Abstract

The present invention relates to a plasma display panel. In a plasma display panel according to an embodiment of the present invention, scan electrodes, sustain electrodes, and scan electrodes are sequentially arranged, and the sustain electrodes have an impedance smaller than that of the scan electrodes. Embodiments of the present invention can reduce the difference between the voltage drop of the scan electrode and the voltage drop of the sustain electrode and can also reduce brightness deviation.

Description

technical field [0001] The present invention relates to a plasma display panel. Background technique [0002] figure 1 A structural perspective view of a plasma display panel in the related art is given. like figure 1 As shown, the plasma display panel in the related art includes a front panel 100 and a rear panel 110 . The front panel 100 includes a front glass substrate 101 and the rear panel includes a rear glass substrate 111 . The front panel 100 and the rear panel 110 are parallel to each other with a predetermined distance. [0003] A pair of sustain electrodes 102, 103 for sustaining emission of a cell by mutually discharging is formed on a front glass substrate 101. Referring to FIG. Sustain electrode pair 102 , 103 includes scan electrode 102 and sustain electrode 103 . The scan electrode 102 includes a transparent electrode 102a formed of a transparent ITO material and a bus electrode 102b formed of a metal material. The sustain electrode 103 includes a tra...
