Abstract
There is provided a PDP device capable of suppressing generation of erroneous discharge during the entire cell initialization period and generation of flickering in a low gradation if the voltage applied to the data electrode is increased for fine resolution when characteristic irregularities are generated in the panel plane or a discharge start voltage lowered area is generated by a long period of drive. A method for driving the PDP device is also disclosed. A pulse Pul.3 to a data electrode Dat is performed at timing t0, i.e., with temporal relationship preceding to timing t1 for increasing the potential of the scan electrode Scn to Vq(V). Accordingly, in this drive method, at timing t0 when voltage Vx(V) is applied to the data electrode Dat to generate discharge Dis.3, no potential difference exists between the scan electrode Scn and the sustain electrode Sus. The discharge Dis.3 generated between the data electrode Dat and the sustain electrode Sus by the lowering of the discharge start voltage serves as a trigger and spreads to the side of the scan electrode Scn without causing erroneous discharge.
Description
Technical field
The present invention relates to plasma display panel device and driving method thereof, the technology of the generation that misplaces electricity during the initialization when particularly suppressing to drive.
Background technology
In plasma display, the formation that has become now the panel (below, only note is made " PDP ") of the interchange surface discharge type of main flow is, 2 panels of determining are opposed mutually, the gap is reserved in the centre, seals at outer part, and inner the filling comprises xenon discharge gass such as (Xe).1 formation of determining (front panel) in 2 panels is, it is right to form a plurality of show electrodes on an interarea of glass substrate, and lamination dielectric layer and protective seam in order are with its covering.
In addition, the formation of another panel (rear panel) is, with the interarea of the relative side of front panel of glass substrate on form a plurality of data electrodes, and the lamination dielectric layer covers it.In addition, rear panel has parallel with data electrode and is located at partition between the adjacent data electrode.This partition plays a part to keep the gap with front panel.Between partition, each red, green, blue luminescent coating forms by each applying colour respectively.Have, front panel and rear panel are configured on the electrode pair and the cross one another direction of data electrode of formation again.
With PDP as the formation of the PDP device of display panel be, above-mentioned each electrode is connected with driver, each driver is connected with the drive control part that utilizes a son method (in time cut apart gray level display mode) that drive signal takes place.In the driving of PDP device, the field is divided into a plurality of sons after the weighting, carry out gray level display by controlling the lighting of its each son/non-lighting.During a distribution writes to each son and during keeping, during writing be for the discharge cell of having selected make as produce between a side's of electrode pair scan electrode and the data electrode write discharge during, during keeping be for whole discharge cells at the scan electrode that constitutes electrode pair and keep apply between the electrode alternating voltage discharge cell that has carried out writing is produced keep discharge during (for example, with reference to patent documentation 1).
In addition, in 1, whole discharge cells are set the initialization of whole unit during, make it produce the initialization discharge simultaneously, with the wall electric charge before this of eliminating son and the wall electric charge that is formed for write activity.
As shown in Figure 1, during going up the initialization of whole unit, be divided into first half and when latter half of from the time, at first half, be 0 (V) with the potential setting of keeping electrode and data electrode, scan electrode is applied the acclivity waveform voltage that slowly rises to current potential Vr (V) from current potential Vq (V).Then, utilize this change in voltage produce with scan electrode as anode, will keep faint the 1st the initialization discharge of electrode and data electrode as negative electrode.Secondly,, will keep electrode and be set at current potential Vh (V), under this state, apply the decline ramp waveform voltage that slowly descends to current potential Va (V) from current potential Vg (V) keeping electrode latter half of.Utilize this change in voltage produce with scan electrode as negative electrode, will keep faint the 2nd the initialization discharge of electrode and data electrode as anode.During whole unit initialization, carry out the initialization of whole discharge cells by this twice faint discharge.
In recent years, as a kind of method of the luminescence efficiency that improves PDP, adopt the method that makes the Xe branch pressure rises in the discharge gas.When making Xe branch pressure rises, during the whole unit initialization in existing driving method shown in Figure 1, the strong discharge that first half produces becomes clearly, influenced by it, discharges by force latter half of also the generation sometimes.The strong discharge that takes place during whole unit initialization as shown in Figure 1 forms exactly and to finish and writes same wall electric charge, makes the picture quality variation.
Relative therewith, developed a kind of method, as shown in Figure 2, the first half during whole unit initialization, the current potential of scan electrode just be Vq (V) afterwards, the current potential of data electrode is Vx (V).In the method, before discharging between scan electrode and the data electrode, make scan electrode and keep to produce discharge between the electrode, make it produce stable initialization discharge (improvement prior art).This is based on a kind of like this mechanism and resolves, promptly because 2 electron emission coefficiencies of protective seam and luminescent coating are variant, so, data electrode is stablely next as the discharge of negative electrode with keeping electrode as the discharge ratio of negative electrode.

Summary of the invention
But, in the PDP device, sometimes discrete or drive etc. former thereby produce scan electrode in panel, keep mutual discharge ionization voltage such as electrode and data electrode than other regional low zones for a long time because of the characteristic in the panel, this phenomenon becomes more obvious because of the Xe in the discharge gas divides the rising of air pressure.Because such reason, even existing technology has been carried out above-mentioned improved PDP device, as shown in Figure 2, sometimes also can be because of the data electrode application voltage being produced even involving the strong discharge of keeping the electrode side, and the influence of the discharge that produces because of this first half makes the latter half of strong discharge that also produces.
Like this, when having regional that discharge ionization voltage descends, the first half during whole unit initialization as above-mentioned improvement prior art can not fully guarantee the quality of image to the method for data electrode application voltage Vx (V).
In addition, in recent years, the high-definition that carries out along with the requirement that adapts to overall height sharpness (full high vision) etc. tends to during writing the data electrode be applied the voltage higher than the past.This is because the discharge at following high-definition between the adjacent discharge cell is interfered to be increased, and is necessary be not subjected under the situation that influences of this interference, can carry out write activity reliably.
From the viewpoint that cost and circuit constitute, the magnitude of voltage that during wishing voltage Vx (V) that the first half during whole unit initialization applies the data electrode and writing the data electrode is applied is general.Therefore, as the countermeasure that the discharge between the neighboring discharge cells is interfered, the voltage that during raising writes the data electrode is applied can make the voltage Vx (V) that the data electrode is applied during the initialization of whole unit rise.Therefore, under these circumstances, the zone that not only exists discharge ionization voltage to descend, and have the tendency that begins to discharge with above-mentioned voltage from the beginning, this discharge can cause the discharge interference of low gray level.Therefore, in the PDP device, advance the high-definition degree just to be easy to generate the problem of the flicker of hanging down gray level region more more.
The present invention proposes in order to solve such problem, its purpose is to provide a kind of PDP device and driving method thereof, even under the situation in or long-term former thereby the zone that generation discharge ionization voltage descend that drive discrete because of the characteristic in the panel, perhaps, make applying under the situation that voltage rises of data electrode following high-definition, also can suppress the generation of the flicker of generation that misplaces electricity during the initialization of whole unit and low gray level.
The present inventor is on the basis that the mechanism of the strong discharge that produces because of the voltage that above-mentioned data electrode is applied Vx (V) is analyzed, such shown in the initialization luminous 2 of discovery image pattern 2, in the zone that discharge ionization voltage descends, because of the voltage Vx (V) that the data electrode is applied, at data electrode with keep between the electrode and discharge, at this moment, because of scan electrode with keep and have potential difference (PD) Vq (V) between the electrode, so above-mentioned discharge also feeds through to the discharge of scan electrode side as triggering, thereby makes its discharge develop into strong discharge.
The present invention proposes in view of such viewpoint, achieves the above object by adopting following formation.
About the driving method of PDP device of the present invention for having a plurality of electrode pairs that form by the 1st electrode and the 2nd electrode and a plurality of the 3rd electrode that is configured on the direction of intersecting and discharge space is clipped in the middle with this electrode pair, and with the corresponding panel part that constitutes discharge cell of each crossings on different level part of electrode pair and the 3rd electrode, in by 1 that has carried out respectively that luminance weighted a plurality of sons field constitutes, divide the whole discharge cells of pairing to carry out during initialized whole unit initialization of its wall state of charge, the method is characterized in that: with divide paired the 1st electrode to apply ramp waveform voltage during the initialization of whole unit with anacline and the first half of the 1st initialization discharge takes place during and the 1st electrode applied the ramp waveform voltage with reverse caster and the 2nd initialization discharge latter half of taken place during, during first half, in the timing that takes place prior to the 1st initialization discharge to the 3rd electrode voltage that to apply relative the 2nd electrode be the waveform of positive polarity.
Specifically, the method that can adopt following 2 kinds of methods and they are combined.
(1) making the voltage waveform that during first half the 3rd electrode is applied is the waveform with acclivity waveform portion of anacline.
(2) voltage waveform that will apply the 3rd electrode during first half is set regularly to begin timing regularly prior to the rising of voltage waveform that the 1st electrode is applied in the beginning that makes its acclivity waveform portion.
In addition, relevant PDP device of the present invention is characterised in that: drive division is carried out the display driver of panel part according to above-mentioned driving method.
In relevant PDP device of the present invention and driving method thereof, adopt during the first half during whole unit initialization, in the formation of the timing that takes place prior to the 1st initialization discharge to the voltage of the 3rd electrode waveform that to apply relative the 2nd electrode be positive polarity.Therefore, in relevant PDP device of the present invention and driving method thereof, even because of discrete and long-term driving the in the panel makes under the situation that discharge ionization voltage descends, also can the first half during whole unit initialization produce will have influence on write during and keep during such strong discharge.Specifically, can adopt above-mentioned (1) and (2) and then with these 2 kinds of method composite methods.For example, when adopting the method for above-mentioned (1),,, also can make this discharge become weak discharge, can suppress it and reach to the 1st electrode side wave even produce discharge when to the 3rd electrode application voltage and between the 2nd electrode by using ramp waveform at rising part.Therefore, in relevant method of the present invention, can be suppressed at effectively and can involve the such strong discharge during influence writes of the 1st electrode side during the first half during the initialization of whole unit.Therefore, when adopting this method,, also can suppress misplacing during the initialization of whole unit effectively even because of discrete in the panel or drive etc. former thereby the discharge ionization voltage in the part zone of panel is descended for a long time.Here, about ramp waveform, in " ASIA DISPLAY ' 98, pp.23～27 " etc., be documented, in addition, about the slope of waveform, because of in No. 3394010 communique of Jap.P. etc., being documented (for example 9V/ μ sec), so omit its explanation here.
In said method (1), though with to the 1st electrode application voltage in or voltage during carrying out first half thereafter to the 3rd electrode apply, also can suppress to misplace the generation of electricity.At this moment, the action effect of generation that misplaces electricity during suppressing the initialization of whole unit, also has the extra withstand voltage advantage that to guarantee data driver because of the amount of contraction (wringing) of the potential change of the 3rd electrode.Therefore, as if this method of employing, can reduce the cost of whole device.
In the method for above-mentioned (1), from the viewpoint of the generation that suppresses to misplace electricity, hope will be set than the slope mitigation of the rising part of the voltage waveform that during writing the 3rd electrode is applied at the slope of the acclivity waveform portion of the voltage waveform that during the first half the 3rd electrode is applied.
In addition, when adopting said method (2), because of to the timing of the 3rd electrode application voltage prior to regularly to the beginning of the 1st electrode application voltage, even so because of discharging to producing between the 3rd electrode application voltage and the 2nd electrode, but because of between this moment the 1st electrode and the 2nd electrode, not having potential difference (PD), so this discharge can not trigger and make discharge develop into strong discharge.Therefore, adopting under the situation of this method,, misplacing the generation of electricity in also can suppressing during the initialization of whole unit even because of discrete in the panel or drive for a long time the discharge ionization voltage in part zone is descended.
Under the situation that adopts said method (2), the beginning timing setting of wishing the acclivity waveform portion of the voltage waveform that will apply the 3rd electrode becomes the rising with the voltage waveform that the 1st electrode is applied to begin regularly to be separated by a period of time, in this time, even because of producing discharge between this voltage application and the 2nd electrode, the influence of this discharge is eliminated totally.
In two methods of above-mentioned (1) and (2),, wish to become when the 2nd electrode is begun to apply voltage, to make the voltage that the 3rd electrode is applied to descend wave setting for the timing of beginning during latter half of.
In addition, in two methods of above-mentioned (1) and (2), wish at least to set the amplitude of the interior voltage waveform that the 3rd electrode is applied during the first half according to the side in driving time and the panel temperature.If set like this, can produce stable initialization discharge and be not subjected to the influence of discharge instability factors such as driving time or panel temperature.For example, can set the amplitude that makes the voltage waveform that the 3rd electrode is applied along with the prolongation of driving time for increases.
In addition, in two methods of above-mentioned (1) and (2), wish to set for two sons of the 2nd son that makes during comprising the 1st son that has during the initialization of whole unit in 1 and not having the initialization of whole unit, the 1st son shared ratio in 1 is set according to the average picture level (Average Picture Level:APL) of this image.That is, in the high field of APL, because of thinking that black image display area is narrow,, therefore, can make the discharge stability that writes during writing, simultaneously, can encourage (priming) to measure by increase and make discharge stability so increase the son that comprises during the initialization of whole unit.On the other hand, in the low field of APL, because of thinking that black image display area is wide,, can improve the black display quality so reduce the sub-field that comprises during the initialization of whole unit.
In addition, in relevant PDP device of the present invention and driving method thereof, can adopt a kind of like this formation, promptly, voltage waveform for during the first half during whole unit initialization the 3rd electrode being applied goes to set the timing of its potential change according at least one side in driving time and the panel temperature.In addition, in relevant PDP device of the present invention and driving method thereof, also can adopt a kind of like this formation, that is,, set the timing of " height " according to APL for the voltage waveform that during the first half during whole unit initialization, the 3rd electrode is applied.In addition, in relevant PDP device of the present invention and driving method thereof,, also can set its amplitude according to APL for the voltage waveform that during the first half during whole unit initialization, the 3rd electrode is applied.
And then, better effects if when device that relevant PDP device of the present invention and driving method thereof are used for panel part and have the resolution more than " HD ".Promptly, along with realizing high-definitions such as corresponding with the overall height sharpness, even be necessary to improve the voltage that the data electrode is applied,, also can suppress the discharge that data electrode application voltage (height) is produced because of during whole unit initialization if adopt relevant PDP device of the present invention and driving method.Therefore, even if relevant PDP device of the present invention and driving method thereof also can prevent the flicker of low gray level region for high-definition.
As mentioned above, in relevant PDP device of the present invention and driving method thereof, even under the situation in or long-term former thereby the zone that generation discharge ionization voltage descend that drive discrete because of the characteristic in the panel, perhaps, make the applying under the situation that voltage rises of data electrode along with high-definition, also can suppress reliably during the initialization of whole unit the generation that misplaces electricity and in the generation of the flicker of low gray level.

T during writing
2In, the current potential of scan electrode Scn (1)～Scn (n) is temporarily remained on the Vs (V).Then, in data electrode Dat (1)～Dat (m), the data electrode Dat (i) of the discharge cell that should show the 1st row apply amplitude be Vw (V) write pulse Pu1.5, simultaneously, to the scan electrode Scn (1) of the 1st row apply amplitude be Vb (V) negative polarity write pulse Pu1.4.At this moment, the voltage of the cross section of data electrode Dat (i) and scan electrode Scn (1) becomes and externally applies voltage (Vw-Vb) and add the voltage sum that is produced behind wall electric charge on the data electrode Dat (i) and the wall electric charge on the scan electrode Scn (1), surpasses discharge ionization voltage.
By as above-mentioned write discharge, in the discharge cell of having selected, between data electrode Dat (i) and scan electrode Scn (1), reach scan electrode Scn (1) and keep to produce between the electrode Sus (1) and write discharge, go up the positive wall electric charge of formation at scan electrode Scn (1), keeping the upward negative wall electric charge of formation of electrode Sus (1), going up at data electrode Dat (i) and form the wall electric charge of bearing.So, in the discharge cell that the 1st row should show, carry out the write activity that on each electrode Scn (1), Sus (1), Dat (i), carries out the formation of wall electric charge by writing discharge.
On the other hand, because of the voltage of the cross section that do not apply the data electrode Dat that writes pulse Pu1.5 and scan electrode Scn (1) surpasses discharge ionization voltage, so do not write discharge.T during writing

T2 does not write in the discharge cell of discharge during writing, and keeps pulse Pu1.6 and does not keep discharge yet even apply.Therefore, the wall state of charge of T1, T4 finish time during this discharge cell is kept initialization.
Then, make the current potential of scan electrode Scn (1)～(n) get back to 0 (V), and to keep electrode Sus (1)～Sus (n) apply amplitude be Vm (V) keep pulse Pu1.7.Apply by this, because of above-mentioned scan electrode Scn (1)～Scn (n) is applied pulse Pu1.6 and produces in the discharge cell of keeping discharge, scan electrode Scn (j) and the voltage of keeping between the electrode Sus (j) surpass discharge ionization voltage, produce and keep discharge.Have again,, do not produce at this child field SF and keep discharge above-mentioned scan electrode Scn (1)～Scn (n) being applied pulse Pu1.6 and not producing in the discharge cell of keeping discharge.

5. the superiority that has PDP device 1 and driving method thereof
By the PDP device 1 of relevant this example and the advantage that driving method had thereof relatively being described with the driving method (driving method of improvement prior art) of Fig. 2.
As mentioned above, in the driving method of the relevant improvement prior art of Fig. 2, scan electrode Scn (1)～Scn (n) is being applied voltage Vq (V) afterwards, data electrode Dat (1)～Dat (m) is being applied voltage V
x(V), so, in face, produce under the situation in the low zone of discharge ionization voltage, perhaps, because of high resolving powerization to the situations such as voltage rising that data electrode Dat (1)～Dat (m) applies under, by voltage V to data electrode Dat (1)～Dat (m) applies
x(V), at data electrode Dat (1)～Dat (m) with keep between electrode Sus (1)～Sus (n) and to produce discharge.
At this moment, because of the current potential of scan electrode Scn (1)～Scn (n) becomes Vq (V), so above-mentioned data electrode Dat (1)～Dat (m) and the discharge of keeping generation between electrode Sus (1)～Sus (n) become a kind of triggering, make it also extend to scan electrode Scn (1)～Scn (n), make and in discharge cell, develop into strong discharge.
Promptly, in the prior art of improvement, though when the discharge ionization voltage in panel part is not discrete, produce effect for the occurrent strong discharge during the initialization of whole unit, but disperse in because of panel or long-term driving etc. makes under the situation that produces the low zone of discharge ionization voltage in the face, perhaps, because of high resolving powerization to the situations such as voltage rising that data electrode Dat (1)～Dat (m) applies under, the result is to voltage V that data electrode Dat (1)～Dat (m) applies
x(V) can in this zone, bring out strong discharge.
Relative therewith, in the driving method of the PDP of relevant this example device 1, as shown in Figure 6, in timing t
0, promptly according to prior to making scan electrode Scn (1)～current potential of Scn (n) rise to the time relationship of the timing t 1 of Vq (V), carry out data electrode Dat (1)～Dat (m) applied pulse Pu1.3.Therefore, in the driving method of relevant example shown in Figure 6, data electrode Dat (1)～Dat (m) is applied voltage V
x(V), therefore, in the timing t that produces discharge Dis.3
0, at scan electrode Scn (1)～Scn (n) with keep between electrode Sus (1)～Sus (n) and do not have potential difference (PD).Therefore, in the method, data electrode Dat (1)～Dat (m) and keep between electrode Sus (1)～Sus (n) the discharge Dis.3 that produces and can not become a kind of triggering making discharge feed through to scan electrode Scn (1)～Scn (n) side.
In addition, in the driving method of relevant this example, because of T during whole unit initialization
1First half T
11Data electrode Dat (1)～Dat (m) is applied the pulse Pu1.3 of positive polarity, thus the same with the prior art of above-mentioned improvement, can produce stable initialization discharge.
As mentioned above, in the PDP of relevant this example device 1 and driving method thereof, even for the situation that in face, produces the low zone of discharge ionization voltage, perhaps, because of high resolving powerization to the situations such as voltage rising that data electrode Dat (1)～Dat (m) applies, can be at T during whole unit initialization
1Produce unwanted strong discharge, can guarantee high-quality picture performance.
Have again, in the driving method of the PDP of relevant this example device 1, each amplitude Vx (V), Vw (V) to pulse Pu1.3, Pu1.5 that data electrode Dat (1)～Dat (m) applies not necessarily must be same values, but, wish that they are identical magnitudes of voltage from the viewpoint of power supply number with the simplification of relevant therewith circuit structure etc.
6. T during whole unit initialization
1In the performed step of display driver portion 20
Below, use Fig. 7 and Fig. 8 explanation T during whole unit initialization
1The drive controlling that middle display driver portion 20 opposite boards 10 are carried out is handled.
At first, timing pip generating unit 24 has CLK of time clock portion and count section (having omitted diagram in Fig. 4), and the CLK of time clock portion has at interval than each timing t among Fig. 6
0～t
8Each at interval poor also short narrow wide time clock, count section is carried out stored counts to the time clock that is provided by time clock CLK.
As shown in Figure 7, T during whole unit initialization
1Drive controlling in, the count value CT of count section be reset (step S1).Simultaneously, the current potential with data electrode Dat (1)～Dat (m) is set to V
x(V) (step S2).
Secondly, begin to carry out the accumulative total (step S3) of the count value CT of count section, before reaching count value CT=a, continue this state (step S4:N).Then, in the moment of the count value CT=a (timing t that is equivalent to Fig. 6
1), the current potential of scan electrode Scn (1)～Scn (n) is set to V
q(V) (step S5).
As shown in Figure 8, in the timing t of count value CT=a
1Make the current potential of scan electrode Scn (1)～Scn (n) rise to Vq (v) from 0 (V).
Get back to Fig. 7, become the timing t of Vq (V) from the current potential of scan electrode Scn (1)～Scn (n)
1Beginning is with positive slope ((Vr-Vq)/(t
3-t
1)) make voltage rise (step S6).The waveform of this part is the sloping portion from current potential Vq (V) to current potential Vr (V) shown in Figure 8.Then, in the timing t of count value CT=c
3(step S9:Y) makes the current potential of scan electrode Scn (1)～Scn (n) drop to Vg (v) (step S10) from Vr (V).In addition, meanwhile or roughly side by side, make the current potential of keeping electrode Sus (1)～Sus (n) rise to Vh (V) (step S11), make the current potential of data electrode Dat (1)～Dat (m) drop to 0 (V) (step S12).
Secondly, as shown in Figure 7, with negative slope ((Va-Vg)/(t
6-t
4)) make the current potential of scan electrode Scn (1)～Scn (n) descend (step S13).The decline ramp waveform part among the pulse Pu1.1 of applying of this scan electrode Scn (1)～Scn (n) proceeds to (step S14:N) till the count value CT=d always.If use Fig. 8 that this part is described, then be equivalent to slowly drop to the part of Va (V) from current potential Vg (V).
Timing t at count value CT=d
6(step S14:Y) is set to Vs (V) (step S15) with the current potential of scan electrode Scn (1)～Scn (n), the accumulative total of end counter (step S16), and finish T during the initialization of whole unit
1Control and treatment.

1The setting of son SF
Secondly, use Fig. 9 that setting to the son SF in 1 is described in the relevant driving method of this example.Fig. 9 be pattern be illustrated in the son pie graph of the formation of the son in 1 in the driving of PDP device 1.Have again, in Fig. 9, by 10 son SF
1～SF
10Constitute 1 field.
In the driving of the PDP of relevant this example device 1,, advise the formation of stator field SF according to by the APL test section 28 detected data relevant with APL.
In the driving of PDP device 1, comprise simultaneously in 1 and have T during the initialization of whole unit

4Use has T during the initialization of whole unit
1The son.In addition, shown in Fig. 9 (c), when the value of APL at 5[%]～10[%] scope in the time, compare with the situation of Fig. 9 (b), also increased by the 10th a son SF
10, set for and have T during the initialization of whole unit
1The son.

1The son.
As mentioned above, in the driving method of the PDP of relevant this example device 1, according to by the detected APL value of APL test section 28 (with reference to Fig. 4), regulation has T during the initialization of whole unit
1The number of son SF.Here, when the APL value is high, think that black viewing area is narrow image, but in the driving method of relevant this example, because of make under such state have the initialization of whole unit during T
1The number of son SF increase, so can increase energizing quantity, thereby can realize stable discharge.
On the other hand, when the APL value is low, think that black viewing area is wide image, because of make under such state have the initialization of whole unit during T
1The number of son SF reduce, so can guarantee high-quality black demonstration.
Therefore, in the driving method of the PDP of relevant this example device 1, even high luminance area is arranged, as long as the value of APL is low, also can reduce the brightness of black viewing area, the image that degree of comparing is high shows.
In addition, in the driving method of relevant this example, because of T during whole unit initialization
1In, apply the beginning timing t prior to voltage to scan electrode Scn (1)～Scn (n)
1, data electrode Dat (1)～Dat (m) is applied voltage V
x(V), so as mentioned above, even under the situation in the zone that exists discharge ionization voltage to descend because of the discrete or driving for a long time in the panel is local, perhaps, make the applying under the situation such as voltage rising of data electrode Dat (1)～Dat (m) because of high resolving powerization, also can produce stable initialization discharge.
And then, in the PDP of relevant this example device 1,, use fluorescent material as described above selectively as luminescent coating 124R, the 124G of panel 10, the constituent material of 124B.In the fluorescent material that illustrates like this, particularly in the formation of each luminescent coating 124R, 124G, 124B, at Y
