[0048] Before describing the first embodiment ( Figure 10 and 11 ), will describe the general driving waveform ( Figure 9 ) technology of driving the delta unit PDP for comparison with the first embodiment so that the features of the first embodiment are clearly defined.

[0049] The expression about "on the scan electrode" to be used in the following description will now be described. The expression "on" refers to the position of a part on the scan electrode when the PDP is mounted such that its screen is perpendicular to the ground and its sustain electrodes are horizontal to the ground. The expressions "under the scanning electrodes" and "above and below the scanning electrodes" should also be understood in the same way.

[0086] Another driving method is described in the second embodiment. According to this method, the address current flowing in the scan electrodes can be reduced (halved), as in the case of the first embodiment. In addition, the address discharge current flowing in the common electrodes (odd-numbered X electrodes and Xo even-numbered X electrodes Xe) can be reduced to half that in the case of the first embodiment.

[0087] More specifically, as Figure 12 and 13 As shown in , the voltage of the common electrode sandwiched between consecutive (adjacent) scan electrodes Yo(n) and Ye(n) ( Figure 13 The odd-numbered X electrodes (Xo) shown in ) are assigned a low voltage Vxh (voltage in the counter-selected state). In addition, the voltage of the other common electrode ( Figure 13 The even-numbered X electrodes Xe shown in ) are assigned a high voltage Vxh (voltage in the selected state). As a result, the discharge cells provided above the scan electrode Yo(n) and the discha...

[0090] The single odd-numbered Y electrode Yo and the single even-numbered Y electrode Ye to be scanned do not necessarily have to be arranged consecutively (adjacently) as in the case of the first and second embodiments. Any odd-numbered Y electrodes Yo and arbitrary even-numbered Y electrodes Ye may be scanned. However, the two electrodes scanned at the same time must include a single odd-numbered Y electrode Yo and an even-numbered Y electrode Ye.

[0091] This embodiment is designated as the third embodiment. Figure 14 A scan unit and an inverse scan unit according to the present embodiment are shown. exist Figure 14 , the selection X voltage Vxh is applied to the even-numbered X electrodes Xe, and the counter-selection X voltage Vxl is applied to the odd-numbered X electrodes Xo.

[0092] However, when the PDP is driven such that the reverse selection X voltage Vxl is applied to the even-numbered X electrodes Xe, and the selection X voltage Vxh is applied to the odd-...

Abstract

A method for driving a PDP having a first electrode on a substrate; a second electrode between the first electrodes; a third electrode intersecting the first and second electrodes; and a discharge cell, which performs The address discharge between the first electrode and the third electrode, and the sustain discharge between the first electrode and the second electrode, and the sustain discharge between the first electrode and the adjacent second electrode can be performed simultaneously, where in In an address period in which address discharge is performed, the odd-numbered electrodes and the even-numbered electrodes of the first electrodes are paired with each other and scanned in a predetermined order, and the address period is divided into first and second periods, wherein in the first period, One of the set of odd-numbered electrodes and the other set of even-numbered electrodes in the second electrode is placed in a selected state, and the other set is placed in an anti-selected state, and in the second cycle, the other set of electrodes is placed in a selected state And another set of electrodes is placed in a counter-selected state for scanning against the first electrodes.

Description

technical field [0001] The present invention relates to a method of driving a plasma display panel and a plasma display device. In particular, the present invention relates to a driving method for reducing an address current in a scan electrode and for reducing a load on a scan driver or reducing the number of scan drivers, driving circuits, and the like. Background technique [0002] First, see figure 1 , describing a plasma display panel (hereinafter referred to as a PDP). figure 1 is an exploded perspective view showing the structure of a pixel in a PDP. On the front substrate 10, two kinds of electrodes 11 and 12 for display are provided so that they are substantially parallel to each other. A plurality of electrodes 11 and 12 are provided on the entire portion of the front substrate 10 in the order shown in the figure. These electrodes 11 and 12 are designated as sustain electrodes. Typically, the sustain electrodes are formed of transparent electrodes 11i and 12i,...
