Fig. 3 is the block scheme of PDP according to an exemplary embodiment of the present invention.
As shown in Figure 3, PDP comprises plasma panel 100, addressing driver 200, Y electrode driver 320, X electrode driver 340 and controller 400 according to an exemplary embodiment of the present invention.

Fig. 4 shows the figure that is used to present the drive waveforms that is applied to PDP of first exemplary embodiment according to the present invention.
As shown in Figure 4, according to first exemplary embodiment of the present invention, the Y electrode is divided into a plurality of groups according to the order of scanning Y electrode, and when scanning voltage is applied to the Y electrode successively, sets different scanning voltages for different groups.And, be applied to first group (after the decline ramp cycle in the reset cycle at scanning voltage, being applied with scanning voltage on it) before the Y electrode of in addition each group, the cycle that is used for reducing in the mode that is similar to the decline ramp resetting cycle voltage at Y electrode place is comprised in addressing period.Illustrate, convenient for the description of Fig. 4, the Y electrode is divided into three groups (that is, first, second and the 3rd scanning group).
After the voltage at Y electrode place reduced to voltage VscL1 in the reset cycle that descends, the scanning impulse with voltage VscL1 was applied to first scanning group successively, and voltage VscH1 is applied to the Y electrode in addressing period simultaneously.At this moment, when the addressing operation of first scanning group finished, the voltage at Y electrode place was VscL1.
In the discharge cell of the Y electrode that comprises second scanning group, the scanning voltage pulse with voltage VscL1 can not stably produce address discharge, and this is because wall voltage is eliminated when the scanning voltage pulse is applied to first scanning group.Therefore, before second scanning group was addressed, the voltage at Y electrode place reduced to voltage VscL2 from voltage VscL1.Between X electrode and Y electrode, produce weak discharge, and eliminate the wall electric charge to be similar to the mode that in the reset cycle, applies the decline ramp waveform.Therefore, the state of discharge cell changes, thereby makes the easier addressing-discharge of carrying out therein.Therefore, when the scanning impulse with voltage VscL2 when this state is applied to the Y electrode of second scanning group successively, stably produce address discharge.At this moment, for the addressing condition of creating second scanning group addressing condition with corresponding first scanning group, the voltage that is applied to non-selected sweep trace reduces to voltage VscH2.
The scanning voltage pulse is applied to second scanning group successively, the scanning voltage pulse be applied to the 3rd scanning group in order to the address discharge efficient that increases by the 3rd scanning group before, the voltage of Y electrode reduces to voltage VscL3 gradually from voltage VscL2, and the scanning voltage pulse with voltage VscL3 is applied to the Y electrode of the 3rd scanning group successively.Voltage difference between the voltage of VscL2 and VscL3 for example can and the voltage of VscL1 and VscL2 between voltage difference basic identical.
According to first exemplary embodiment of the present invention, although before scanning voltage is applied to a Y electrode except each group of first group, compensate by further comprising the voltage that is used for reducing gradually Y electrode place than the wall loss of charge of the addressing electrode on the lower part at panel, bigger than X electrode in the lower part and the voltage difference between the Y electrode at panel, this is because the voltage at X electrode place is biased to predetermined voltage in addressing period.Correspondingly, can produce discharge in the unit that is not addressed in the cycle of keeping, this is because can produce discharge in the non-selected discharge cell between X electrode and Y electrode in addressing period.
Correspondingly, in second exemplary embodiment of the present invention, in addressing period, for each group, the bias voltage at X electrode place reduces the voltage minimizing with Y electrode place gradually.To be described with reference to Figure 5 second exemplary embodiment of the present invention.
Fig. 5 shows the drive waveforms of the PDP of second exemplary embodiment according to the present invention.
As shown in Figure 5, the drive waveforms of the drive waveforms of second exemplary embodiment and first exemplary embodiment is basic identical according to the present invention, except for each group the voltage at X electrode place is set at (promptly the differing from one another) of variation in addressing period.
According to the order that applies scanning impulse the Y electrode is divided into a plurality of groups, and scan pulse voltage is set at variation, just as under the situation of first exemplary embodiment of the present invention for each group.In addition, in second exemplary embodiment of the present invention, the X electrode is divided into a plurality of groups with the respective sets corresponding to the Y electrode.When scanning voltage in addressing period was applied to a Y electrode of each group, the voltage at the X electrode place of each group reduced and the voltage minimizing at Y electrode place simultaneously.
Just, voltage VscH1 is applied in the Y electrode in addressing period, and the scanning impulse with voltage VscL1 is applied to first scanning group successively, and is biased to voltage Ve corresponding to the X electrode group of first scanning group.
When the addressing operation of first scanning group finishes, second group be addressed before, the voltage at Y electrode place reduces to voltage VscL2 gradually from voltage VscL1.At this moment, be reduced to less than the voltage Ve1 of voltage Ve corresponding to the bias voltage of the X electrode group of second scanning group.Because along with the minimizing X electrode of the voltage at the second scanning group place and the increase of the voltage difference between the Y electrode have been compensated, so do not produce discharge wrong in the cycle of keeping.
Scanning impulse with voltage VscL2 is applied to second scanning group and addressing operation successively to be finished, and before the scanning voltage pulse was applied to the 3rd scanning group, the voltage at Y electrode place reduced to voltage VscL3 gradually from voltage VscL2.And the bias voltage at the X electrode place corresponding with the 3rd scanning group is reduced to less than the voltage Ve2 of voltage Ve1, has therefore compensated the increase of the voltage difference between X electrode and the Y electrode.
Be applied to that the voltage Ve of X electrode can and be applied to the voltage Ve1 of X electrode with voltage difference between the voltage VscL1 that is applied to Y voltage and the voltage difference that is applied between the voltage VscL2 of Y electrode is basic identical or different.In addition, be applied to the voltage Ve2 of X electrode can and be applied to the voltage Ve1 of X voltage with voltage difference between the voltage VscL3 that is applied to Y voltage and be applied to the voltage difference between the voltage VscL2 of Y electrode and/or be applied to the voltage Ve of X electrode and the voltage difference that is applied between the voltage VscL1 of Y electrode basic identical or different.
In second exemplary embodiment of the present invention, can be set to variation corresponding to the voltage of the X electrode group of each scanning group.Yet in the 3rd exemplary embodiment of the present invention, even when the voltage difference between X electrode and the Y electrode is maintained at the voltage that does not produce erroneous discharge in the cycle of keeping, reduce the voltage at Y electrode place, the bias voltage at X electrode place also is maintained at predetermined voltage, and does not reduce described bias voltage.In Fig. 6, when first scanning group and second scanning group were addressed, the bias voltage at X electrode place was maintained at voltage Ve, and when the 3rd scanning group was addressed, the bias voltage at X electrode place reduced to voltage Ve2.Correspondingly, because the voltage level of the bias voltage that applies at X electrode place has reduced, so number of power sources has reduced.
In Fig. 6, be applied to that the voltage Ve2 of X electrode can and be applied to the voltage Ve of X electrode with voltage difference between the voltage VscL3 that is applied to Y voltage and the voltage difference that is applied between the voltage VscL1 of Y electrode is basic identical or different.In addition, be applied to that the voltage Ve2 of X electrode can and be applied to the voltage Ve of X electrode with voltage difference between the voltage VscL3 that is applied to Y voltage and the voltage difference that is applied between the voltage VscL2 of Y electrode is basic identical or different.
Though Fig. 4-6 shows the drive waveforms of single son field, those of ordinary skill in the art will recognize that drive waveforms of other son fields can be basic identical with each drive waveforms shown in Fig. 4-6.For example, Fig. 7 shows the drive waveforms of first and second sons, and wherein each is basic identical with the son field of Fig. 5.
Though scanning voltage is basic identical with the voltage before each group applies the scanning voltage pulse in first to the 3rd exemplary embodiment, these two voltages can be set to and change (that is difference) each other.
And, be equipped with scanning voltage between the scanning group poor, be voltage VscL1 with voltage VscL2 between voltage difference and the voltage difference between voltage VscL2 and the voltage VscL3 can be set to mutually the same or variation (promptly different).
For each height field, voltage difference can be set at is identical or variation, and for each height field, scanning group can be set at identical or variation.For example, the Y electrode in other son can be grouped into and first (Y electrode Y11, Y12...), second (Y electrode Y21, Y22...) and identical or different a plurality of scanning group of the 3rd scanning group (Y electrode Y31, Y32...) shown in Fig. 4-6.
According to aforesaid the present invention, according to scanning sequency the Y electrode is divided into a plurality of groups, and when scanning voltage is applied to the Y electrode successively, the scanning voltage of each group is set at variation.Be applied at scanning voltage before the Y electrode of each group except first group, the cycle that also comprises the voltage that is used for reducing gradually Y electrode place, and discharge cell recovered the state after the reset operation before applying scanning voltage, and had therefore improved address discharge efficient.
And when when the voltage at addressing period Y electrode place reduces, the bias voltage at X electrode place can reduce, and the voltage difference between X electrode and the Y electrode compensated, and does not therefore produce the discharge of mistake in the cycle of keeping.
Although some exemplary embodiment of the present invention described above, those of ordinary skill in the art should be appreciated that under the situation that does not deviate from the spirit or scope of the present invention can carry out various modifications and variations to described embodiment.Therefore, the present invention has often covered the modifications and variations of the present invention within the scope of claims and equivalent thereof.
