Description
Technical field
The present invention is relevant with plasma display panel drive method; Particularly, use with selectivity and selectivity to eliminate the driving method that walks abreast relevant; Be that to produce the plasma display panel drive method of stable address discharge relevant.
Background technology
Plasma display panel (PDP) (Plasma Display Panel: hereinafter to be referred as " PDP ") is He (helium)+Xe (xenon), Ne (neon)+Xe (xenon), produce ultraviolet ray when the inert mixed gas of He (helium)+Xe (xenon)+Ne (neon) etc. discharges, and utilize ultraviolet ray excited light-emitting phosphor to come the method for display image.Such PDP just develops into ultra-thinization easily, giant-screenization, and, optimize the quality of picture more along with the raising of technology.
With reference to Fig. 1 as seen, the discharge cell of 3 traditional electrode surface discharge type PDP is by scan electrode (Y), keeps electrode (Z) and scan electrode (Y) and keeps the addressing electrode (X) that electrode (Z) becomes orthogonal to form and form.
At scan electrode (Y), keep the cross part of electrode (Z) and addressing electrode (X), be provided with unit (1) in order to show any color in redness, green, the cyan.Scan electrode (Y) and keep electrode (Z) and be arranged on the not shown upper substrate.Insulator layer and MgO protective seam not shown on upper substrate form lamination.Addressing electrode (X) is to form on not shown lower basal plate.On lower basal plate, between the unit of horizontal direction adjacency, for the mixing that prevents light, electric signal is provided with barrier.Be provided with the fluorophor that produces visible light with excited by vacuum ultraviolet in lower basal plate and barrier surface.Discharge space between upper substrate and the lower basal plate injects inert mixed gas He+Xe, Ne+Xe, He+Xe+Ne etc.
This 3 electrodes exchange surface discharge type PDP and are divided into most height field to drive.Between each son field, become time number of ratio luminous owing to form, so gray level display is carried out easily with the weight of video data.
Fig. 2 is that traditional selectivity is used and selectivity is eliminated parallel plasma display panel driving method diagrammatic sketch.
With reference to Fig. 2,3 electrode interchange faces discharges PDP driving method to a field (frame or claim the territory), comprises selectivity user formula field (SF1 to SF6) and selectivity cancellation field (SF7～SF12).The 1st son (SF1) is divided into the reset period of closing whole image; Connect the selectivity of selected discharge cell group and use address period; According to address discharge, selecteed discharge cell is kept keeping the phase of discharge; The elimination phase of discharge etc. is kept in elimination in addition.The selectivity that the 2nd to the 5th son (SF2 to SF5) is divided into is separately used address period, is kept phase, elimination phase etc.The 6th son (SF6) is divided into selectivity to be used address period and keeps two kinds of phases.To the 1st to the 6th son (SF1 to SF6), its selectivity is used address period and elimination phase, is unified in each son field; Increase with 2n (n=0,1,2,3,4,5) ratio and keep each son field of phase.The the 7th to the 12nd son (SF7 to SF12) is the selection elimination group (its front does not write the phase) that whole image writes, and it can be divided into closes the selectivity elimination address period of selecting discharge cell and do not have selected discharge cell to keep keeping the phase of discharge.To the 7th to the 12nd son (SF7 to SF12), the unified selectivity that is provided with is eliminated address period and is kept the phase.To the 7th to the 12nd a son group (SF7 to SF12), its phase of keeping is arranged to have unified luminance state ratio with the 6th son (SF6), promptly is set to 25 luminance state ratio.
The the 7th to the 12nd son group (SF7 to SF12) that the selectivity cancellation drives, each height field group running hours, in order to close the discharge cell that there is no need, preceding face field must be in on-state.For example, in order to connect the 7th son (SF7), its preceding face field is that the 6th son (SF6) that the selectivity use-pattern drives must be in on-state.Like this, connect the 6th son (SF6) after, the 7th to the 12nd in (SF7 to SF12), to unnecessary discharge cell, one then a ground close continuously.For this reason, eliminate son (ESF), use son (WSF) promptly in the 6th son field (WSF), keep discharge, must keep on-state according to the on-unit group in last selectivity in order to use selectivity.Simultaneously, the 7th son (SF7), for selectivity is eliminated addressing mode, the discharge that writes in addition becomes and there is no need.Simultaneously, the 8th to the 12nd a son group (SF8 to SF12) does not write under the discharge scenario in front, to being in the unit group of on-state in the former son field, carries out selectivity and closes.
Fig. 3 is illustrated PDP driving method drive waveforms figure in Fig. 2.
With reference to Fig. 3 as seen, the rising stage (SU) to the 6th selectivity is used son (SW6) initial phase,, provide acclivity waveform (RP) to scan electrode (Y).According to this acclivity waveform (RP), produce discharge in the whole image unit group.According to the discharge of rising, at addressing electrode (X) with keep electrode (Z) and go up accumulation positive polarity wall electric charge; Go up accumulation negative polarity wall electric charge at scan electrode (Y).To decrement phase (SD), acclivity waveform (RP) is provided after, scan electrode (Y) is introduced than acclivity waveform (RP) maximum voltage decline ramp waveform low and that descend from positive polarity voltage (RP).
The decline ramp waveform (RP) drops to the 1st scan reference voltage (Vyw1) of wall electric charge negative polarity (-).Simultaneously, introducing the decline ramp waveform at scan electrode (Y) (RP), gives and keeps the 1st DC voltage (Zdc1) that electrode (Z) provides positive polarity (+).The decline ramp waveform (RP) produces faint elimination discharge, eliminates too much wall electric charge of part with this in the unit group.According to the discharge that descends, stable for making address discharge, its required wall electric charge remains in the unit group uniformly.
In address period, provide positive polarity (+) the 2nd DC voltage (Zdc2) to keeping electrode (Z).At this moment, the 2nd DC voltage (Zde2) has than the low magnitude of voltage of the 1st DC voltage (Zdc1).Keep provide the 2nd DC voltage (Zdc2) on the electrode (Z) during, to scan electrode (Y) and addressing electrode (X), supply with synchronous negative polarity (-) selectivity separately and use scanning impulse (SWSP) and positive polarity (+) selectivity use digit pulse (SWDP).At this moment, negative polarity (-) selectivity uses scanning impulse (SWSP) to have 2nd scan reference voltage (Vyw2) value lower than the 1st scan reference voltage (Vyw1) of rising stage (SD).When the wall voltage that the voltage difference of scanning impulse (SWSP) and digit pulse (SWDP) and initialization phase are produced is carried out addition, the generation address discharge unit of call number word pulse (SWDP) in.According to this address discharge, introduce in the selected cell group to form when keeping voltage (Vs) and can keep the wall electric charge that produces discharge.
Use in selectivity and to keep the phase, to scan electrode (Y) and keep introducing that electrode (Z) replaces keep pulse (SUSPy, SUSPz).Unit according to the address discharge selection, wall voltage and keep pulse (SUSPy SUSPz) keeps pulse (SUSPy is in the time of SUSPz) when each the introducing addition time in discharge cell, at scan electrode (Y) with keep between the electrode (Z) to produce and keep discharge, be i.e. mark discharge.In order to make discharge stability, (SUSPy, SUSPz) about 2～3 μ s degree of its pulse width of cloth get final product to keep pulse usually.This is because keep pulse (SUSPy, SUSPz), though the initial point that it takes place produces discharge later on greatly in 0.5～1 μ s time, but keep pulse (SUSPy, SUSPz) in order to produce the required wall electric charge of discharge next time, need to keep the cause of keeping voltage (Vs) of about 2～3 μ s degree after the discharge generation.
Selectivity is eliminated son group (SE1 to a SE6) reset period and can be omitted.Selectivity is eliminated the address period (APD) of son (SE1 to SE6), scan electrode (Y) and addressing electrode (X), the closing unit of respectively doing for oneself provides synchronous negative polarity (-) selectivity to eliminate scanning impulse (SESP) and positive polarity (+) selectivity elimination data pulse (SEDP).Selectivity is eliminated scanning impulse (SESP), and it can drop to, and (Vyw) high selectivity is eliminated with scanning voltage (Vye) than scan reference voltage.Eliminate the address discharge of son field (SE1 to SE6) according to selectivity, keep discharge for the unit group of not closing is produced, (SUSPy, electrode (Z) and scan electrode (Y) are kept in offering of SUSPz) replacing will to keep pulse.Then next height field is that selectivity is eliminated son, and so present selectivity is eliminated son (SE) and finished initial point, to scan electrode (Y) provide pulse height big keep pulse (SUSPy).Use the last selectivity of son (SW) to eliminate son but next height field is a selectivity,, and keep discharge in the unit group that is switched on of elimination so to scan electrode (Y) with keep electrode (Z) and provide and eliminate pulse (EP) and ramp signal (RAMP).
Fig. 4 to Fig. 6 is the wall state of charge figure when Fig. 3 selectivity is eliminated son field (SE) driven.
With reference to Fig. 4 to Fig. 6, selectivity uses the discharge of keeping of son (SW1 to SW6) to finish, and forms wall electric charge (as shown in Figure 4) on so whole sub-field plates.If selectivity is eliminated son (SE), scanning impulse (SESP) and digit pulse (SEDP) also are not incorporated into the t2 initial point, then do not produce discharge (as shown in Figure 5); Such discharge cell is kept discharge (as shown in Figure 6) at the t3 initial point owing to keep pulse (SUSPz) effect generation.
But, keep pulse (SUSPy, SUSPz) keep voltage (Vs) Tai Gao or selectivity eliminate with scanning voltage (Vye) too low, between t2 initial point scan electrode group (Y) and address electrodes of address electrode group (X) or scan electrode group (Y) and keep that generation misplaces electricity (as shown in Figure 7) between the electrode group (Z).This electricity that misplaces is as Fig. 8, become eliminate discharge the phase of keeping because of not producing discharge, so problem of the expression gray level that existence can not be correct.

Embodiment
Followingly be described in further detail in conjunction with representative instance with reference to Fig. 9 to Figure 14.
Fig. 9 is the PDP driving method drive waveforms figure of the 1st example of the present invention.
With reference to Fig. 9, use rising stage (SU) of the initialization phase of son (SW6) in the 6th selectivity, provide acclivity waveform (RP) to scan electrode (Y).According to acclivity waveform (SP), will form discharge in the unit group of whole image.According to the discharge of rising, at addressing electrode (X) with keep electrode (Z) and go up accumulation positive polarity wall electric charge; Go up accumulation negative polarity wall electric charge at scan electrode (Y).At decrement phase (SD), supply with acclivity waveform (RP) after, will will be low than acclivity waveform (RP) ceiling voltage and decline ramp waveform that descend from positive polarity voltage (RP) be incorporated into scan electrode (Y).The decline ramp waveform (RP) will drop to the 1st scan reference voltage (Vyw1) of negative polarity (-).In scan electrode (Y), introduce the decline ramp waveform simultaneously and (RP), provide positive polarity (+) the 1st DC voltage (Zdc1) keeping electrode (Z).Because the decline ramp waveform (RP) forms faint elimination discharge, therefore eliminates too much wall electric charge of part in the unit group.According to the discharge that descends, can stablize generation for making address discharge, its required wall electric charge evenly remains in the unit group.
In address period, provide positive polarity (+) the 2nd DC voltage (Zdc2) to keeping electrode (Z).At this moment, the 2nd DC voltage (Zdc2) has than the low magnitude of voltage of the 1st DC voltage (Zdc1).Give keep electrode (Z) the 2nd DC voltage (Zdc2) be provided during, provide synchronous negative polarity (-) selectivity to use scanning impulse (SWSP) and positive polarity (+) selectivity use digit pulse (SWDP) separately to scan electrode (Y) and addressing electrode (X).At this moment, the selectivity of negative polarity (-) uses scanning impulse (SWSP) to have 2nd scan reference voltage (Vyw2) voltage lower than the 1st scan reference voltage (Vyw1) of decrement phase (SD).To the voltage difference of scanning impulse (SWSP) and digit pulse (SWDP) with when the wall voltage of initialization phase generation is carried out addition, the unit of call number word pulse (SWDP) produces address discharge.When keeping voltage (Vs), form and keep the required wall electric charge of generation discharge according to introducing in the address discharge selected cell.
Use keeping the phase of son (SW) in selectivity, to scan electrode (Y) with keep electrode (Z), the introducing that replaces keep pulse (SUSPy, SUSPz).According to the selected unit of address discharge, to wall voltage in its unit and keep pulse (SUSPy, when SUSPz) carrying out addition, the each introducing when keeping pulse, scan electrode (Y) and keep to produce between the electrode (Z) and keep discharge, promptly mark discharges.(SUSPy, SUSPz), for keeping discharge stability, its pulse height is approximately kept 2～3 μ s to keep pulse.Though this is because keep pulse (SUSPy, SUSPz) after the starting point of Chan Shenging, in 0.5～1 μ s, produce discharge greatly, but keep pulse (SUSPy, SUSPz), produce the cause of keeping voltage (Vs) of 2～3 μ s degree of approximately need keeping after discharging in order to form the required wall electric charge of next discharge generation.
After the 6th selectivity is used keeping discharge and finishing of a son group (SW6), eliminate the address period of son (SE1), introduce the wall charge stable with decline ramp waveform (WSR) in the 1st selectivity.After wall charge stable introducing decline ramp waveform, eliminate son (SE1) address period (APD) in the 1st selectivity, to scan electrode (Y) and addressing electrode (X) closing unit of respectively doing for oneself, provide the selectivity of synchronous negative polarity (-) to eliminate the selectivity elimination digit pulse (SEDP) of pulse (SESP) and positive polarity (+).This selectivity is eliminated scanning impulse (SESP) and will be dropped to and keep reference voltage than the 2nd (Vyw2) high selectivity is eliminated with scanning voltage (Vye)., be the decline ramp waveform (WSR) that the wall charge stable is introduced here, its function is: because when keeping voltage (Vs) height and causing too much accumulation wall electric charge, it eliminates too much wall electric charge specially; (Vye) situation, it can regulate the decline reference voltage (Vyeb) of decision waveform degree of tilt, thereby eliminates the root that misplaces the electricity generation with scanning voltage to low selectivity elimination.At this moment, decline reference voltage (Vyeb) has than selectivity and eliminates with scanning voltage (Vye) high voltage.Thus, (Vye) bounds can become big with scanning voltage to keep the elimination of voltage (Vs) and selectivity.
Simultaneously, be the decline ramp waveform (WSR) that the wall charge stableization is used, it can eliminate the wall electric charge of the too much accumulation on the addressing electrode (X), and keeps low digital voltage.The whole discharge cell wall of PDP of the present invention electric charge all is arranged to evenly, and the addressing that historical facts or anecdotes is existing stable drives.
This decline ramp waveform of using for the wall charge stableization (WSR), also unified each selectivity that is applicable to is eliminated between the son group (SE1 to SE6).
Figure 10 to Figure 13 is wall state of charge figure when PDP driving method shown in Figure 9 drives.
With reference to as seen in conjunction with Fig. 9 and Figure 10 to Figure 13, use the t1 initial point that discharges after finishing of keeping of son (SW6) in the 6th selectivity, if introduce the too high voltage (Vs) of keeping, so in the discharge cell each electrode as forming too much wall electric charge as shown in Figure 10.At this moment, for reducing the part wall electric charge of overheap on each electrode of discharge cell, to scan electrode group (Y), before introducing son keep pulse (SUSP) after decline slope shape (WSR) is provided.Decline ramp waveform (WSR) is supplied with the t2 initial point (as shown in figure 11) that finishes, and each electrode part bulkhead electric charge is partly eliminated.Because a part of wall electric charge is eliminated, therefore between each electrode of discharge cell group, do not produce discharge.That is,, do not have the t3 initial point of call number word voltage (DP), do not produce and misplace as shown in Figure 12.After, discharge cell is introduced at the t4 point and is kept pulse (SUSPy SUSPz) produces (as shown in figure 13) time and keeps discharge.
Use the t1 initial point that discharge finishes of keeping of son field (SW6) in the 6th selectivity, introduce and keep voltage (Vs) normally, each electrode (as shown in figure 11) formation wall electric charge in the discharge cell.After, the 1st selectivity is eliminated the address period of son (SE1), selectivity is eliminated the voltage ratio selectivity elimination of using scanning impulse (SESP), and (Vye) low, generation misplaces according to the voltage difference between scanning impulse (SESP) and the digit pulse (SEDP) so with scanning voltage.At this moment, in order to prevent to misplace electricity, between the address period that the phase of keeping and the 1st selectivity of the 6th selectivity use (SW6) are eliminated son field (SE1), introduce decline ramp waveform (WSR).In this case, decline ramp waveform (WSR), it uses the rising stage (SD) of the initialization phase of a son group (SW1 to SW6) to remove (RP) the waveform effect of drop angle slope in selectivity.That is because decline ramp waveform (WSR) is eliminated the wall electric charge that a part forms in the unit group, therefore prevent introduce low selectivity eliminate with scanning impulse (SESP) and selectivity elimination with digit pulse (SEDP) between the misplacing of generation.
This decline ramp waveform (WSR) also is applicable to situation between the selectivity elimination group (SE1 to SE6) as above-mentioned method.
Figure 14 is the plasma display panel drive method diagrammatic sketch of the 2nd example of the present invention.
With reference to Figure 14 as seen, the present invention's the 2nd example plasma display panel driving method is: the 6th selectivity is used keeping the phase of son (SW6), to scan electrode (Y) with keep the introducing that electrode (Z) replaces and keep pulse (SUSPy, SUSPz) discharge is kept in formation, promptly, forming mark discharge back is the stabilization of wall electric charge, and scan electrode (Y) is introduced decline ramp waveform (WSR).At this moment, the initial point of the beginning of the decline ramp waveform (WSR) of introducing is to go up at scan electrode (Y) to use the most last last initial point that pulse (SUSPy) keeps keeping voltage (Vs) of keeping.The degree of tilt that this decline ramp waveform (WSR) and the 1st example are unified drops to decline reference voltage (Vyeb).
For after the wall charge stableization introduces decline ramp waveform (WSR), eliminate the address period (APD) of son (SE1) in the 1st selectivity, to scan electrode group (Y) and address electrodes of address electrode group (X), eliminate selectivity elimination digit pulse (SEDP) signal of scanning impulse (SESP) and positive polarity (+) for the selectivity of closing unit separately and provide synchronous negative polarity (-).This selectivity is eliminated scanning impulse (SESP) and is dropped to that (Vyw2) high selective scanning voltage (Vye) than the 2nd scan reference voltage.PDP of the present invention constitutes and action is unified, is the decline ramp waveform (WSR) of wall charge stable introducing, is equally applicable to each selectivity and eliminates situation between the son group (SE1 to SE6).
