[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a driving method of a plasma display device which performs display by utilizing plasma discharge.

[0002]

2. Description of the Related Art Plasma display (PDP: Plasma)
The Display Panel) can be thinned and has a large screen, which is difficult to realize with a cathode ray tube (CRT) that has been widely used in television receivers and computer displays in the past. Expected to be deployed.

FIG. 8 shows the structure of a display panel of a conventional AC type plasma display device. This display panel 100
Has a structure in which a front glass substrate 101 and a rear glass substrate 102 are arranged to face each other, and an electrode pair 10 for discharging for light emission display is provided on the front glass substrate 101 on the display surface side.
7 (sustain electrodes 107X, scan electrodes 107Y) are formed in plural. The electrodes 107X and 107Y are 100 μm
The electrodes are arranged in parallel via a discharge gap of about m, and a bus electrode 108 for reducing electric resistance is integrally attached to each of them. In addition, a dielectric layer 109,
The protective layer 110 is sequentially formed.

On the other hand, a plurality of address electrodes 103 are formed on the rear glass substrate 102 so as to be arranged in a direction orthogonal to the electrode pairs 107. Address electrode 103
A dielectric layer 104 is formed on the above, and a partition wall 105 for partitioning a space for each address electrode 103 is further formed thereon.
Are formed. Between the partitions 105, red (R; Re
Phosphor layers 106 of three primary colors of d), green (G; Green) and blue (B; Blue) are applied and formed periodically.

The discharge space sandwiched between the front glass substrate 101 and the rear glass substrate 102 is hermetically sealed at the peripheral edge and filled with discharge gas. Usually, a mixed gas of neon (Ne), xenon (Xe) or the like is used as the discharge gas, the Xe mixing ratio is about 5%, and the gas pressure of the mixed gas at that time is about 65 kPa.

FIG. 9 is a plan view showing an electrode structure in the display panel 100. Here, the electrode pair 107 and the address electrode 103 form an m × n matrix, and the intersecting region is shown surrounded by a dotted line in the drawing, but each of them constitutes a minimum unit of light emission and It is a corresponding area. This plasma display device operates by supplying a drive pulse to each electrode from a drive circuit connected to the display panel 100, and ON / OFF (light emission / non-light emission) control for each pixel is usually performed in three steps. Be seen. Taking the selective erasing method as an example, FIG. 10A to FIG.
The voltage waveform as shown in (C) is applied.

During the reset period, all the sustain electrodes 107 are
X (X ₁ , X ₂ , ..., X _n ) has a negative voltage, and the scan electrode 1
A positive voltage is applied to 07Y (Y ₁ , Y ₂ , ..., Y _n ) to cause discharge between each electrode pair (reset discharge). As a result, priming (supply of charged particles from auxiliary discharge for smooth discharge) is performed, charged particles and the like are generated in the entire pixel area, and are uniformly accumulated on the surface of the protective layer 110, and before that. All of the written pixel information is erased to bring the entire screen into a uniform charged state. The charges due to the accumulated charged particles are so-called wall charges.

In the subsequent address period, a binary state is formed depending on the presence or absence of charges in each pixel, and ON / OFF data writing is performed. That is, the parallel scan electrodes 107Y
(Y ₁ , Y ₂ , ..., Y _n ) are sequentially pulse-inputted for scanning, and all address electrodes 103 are scanned.
Each of (A ₁ , A ₂ , ... _Am ) corresponds to ON / OFF of a pixel selected by a combination with the scan electrode 107Y to which a voltage is applied (in this case, for an OFF display pixel). ) Data pulses are input in synchronization with the scanning timing on the scanning electrode 107Y side. Since only scan pulses lower than the discharge start voltage are applied to the ON pixel region, no discharge occurs, but in the OFF pixel region, 2
The superimposed voltage of the two pulses exceeds the discharge start voltage to cause address discharge, and the accumulated charge is erased.

During the sustain period, the previously selected ON
The display pixel is caused to emit light to perform display. At this time, an AC pulse (sustain pulse) is applied to all the electrode pairs 107. This time, the potential due to the wall charges becomes a bias, and only the pixels where the wall charges remain, that is, the ON display pixels, reach the discharge start voltage in the discharge gap, and discharge is selectively generated (sustain discharge). In this pixel, the discharge gas emits ultraviolet rays due to the electric discharge, and the ultraviolet rays emit the ultraviolet rays.
The luminescence is caused by the irradiation of the light and is sustained during the discharge period.

In the selective writing method, charges are erased from all pixels at the time of reset, and wall charges are formed in ON display pixels by address discharge (data writing).
The drive during the sustain period is performed in the same manner as in the selective erase.

[0011]

In such a series of operations, if the time from the application of a pulse to the start of discharge (discharge delay time) during sustain discharge is short, the current flows instantaneously in a concentrated manner, and power recovery is sufficient. However, there is a problem in that it cannot be performed, or a large load is applied to the drive circuit, so that the performance cannot be sufficiently exhibited.

Similarly, under the condition that discharge is likely to occur, a specific discharge such as tip discharge may occur. Therefore, every time a pulse is applied, the electrodes 107X and 107X
The current concentrates on the tip of Y. Further, in the normal sustain drive, since the pulse having the same shape is continuously applied, the same situation is repeated in the discharge state. For this reason, the discharge was often generated in the same part of the electrodes. As a result, deterioration of the protective layer 110 locally progresses, causing voltage fluctuations and brightness deterioration.

The tendency of occurrence of such a problem becomes more remarkable when the Xe concentration of the discharge gas is increased in order to increase the brightness.

By the way, the same applicant as the present applicant firstly increased the Xe concentration in the discharge gas significantly compared with the conventional one,
By setting the total gas pressure to 5 kPa or more and 50 kPa or less, a plasma display device having improved luminous efficiency and brightness has been proposed (Japanese Patent Application Nos. 11-201867 and 2).
No. 000-201502, Japanese Patent Application No. 2000-222007
No.). At the same time, the discharge gap between the sustain electrode and the scan electrode is set to be extremely narrow, less than 50 μm, so that the driving voltage can be reduced and the display area per pixel can be reduced to achieve high definition. In addition, the dielectric layer on the sustain electrode and the scan electrode has a thickness of 15 μm or less, which is the conventional value (30 μm
(m to 40 μm), the capacity is increased, the capacity is increased, and the charge storage amount is increased, whereby the drive voltage can be reduced. In the following description, the plasma display device having such a configuration will be referred to as a narrow gap type.

In the narrow gap type, the discharge gap is narrow and the dielectric layer is thin, so that the discharge start voltage of the sustain discharge is low, and the Xe concentration is high, so that the discharge delay time is shortened. That is, the structure is characterized in that the sustain discharge easily occurs. Therefore, in the narrow gap type, the above-mentioned problems in the conventional type are likely to occur, and further devising in driving has been awaited.

On the other hand, of the pulses continuously applied during the sustain period, the first pulse applied first may have a longer discharge delay time than the subsequent second pulse.

FIG. 11 shows the state of discharge delay during sustain driving measured on one of the electrode pairs,
(A) is the voltage waveform of the first pulse and the pulse applied next to this electrode, (B) is its charge / discharge current, and (C) is light emission (photomal output). The display panel used has a discharge gap of 20 μm between the electrode pair, a Xe concentration of 4% in the discharge gas, and a discharge gas pressure of 67 kPa. The driving condition is that the sustain voltage is 140 V and the driving frequency is 64 kHz, and the sustain driving is performed after the rest period of 1 ms.

In this case, the light emission in the first pulse starts 640 ns later than the rising edge thereof. On the other hand, in the pulse following the first pulse, the discharge delay is about 100 ns. This can be explained by the presence or absence of the priming effect. That is, at the time of application of the first pulse, since there is a time immediately after the address period, there is a gap from the previous discharge performed at the time of data writing or reset,
The priming effect due to these discharges is reduced. Therefore, since the discharge is mainly caused by the wall charges, the discharge is relatively unlikely to occur and the discharge delay time becomes long. But,
In the subsequent pulse application, the discharge delay time is short and almost constant because of sufficient priming due to the discharge by the first pulse.

The present invention has been made in view of such problems, and an object thereof is to provide a driving method of a plasma display device capable of stabilizing discharge.

[0020]

According to a method of driving a plasma display device of the present invention, a first sustain pulse that rises sharply at a rise time t ₀ is applied to at least one of the electrode pairs, and then the electrode pairs are applied. , A second sustain pulse that rises at a rise time t ₁ (t ₁ > t ₀ ) longer than the first sustain pulse is alternately applied continuously according to the light emission period, and discharge is continuously performed. The light emitting display is performed.

In the method of driving the plasma display device according to the present invention, the first sustain pulse is steeply raised, which unnecessarily shortens the discharge delay time. The second sustain pulse applied after the first sustain pulse is gently raised,
The discharge delay time is extended to the extent that electric power can be sufficiently recovered.

[0022]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[First Embodiment] FIG. 1 shows a schematic structure of a plasma display device driven by a driving method according to a first embodiment of the present invention. FIG. It is a figure which shows the structure of a panel. This device is of a narrow gap type, and has a general configuration except for the display panel 10. Therefore, with respect to the drive circuit portion, illustration and description thereof are omitted except for the sustain driver 21 and the data driver 22 which are connected to the display panel 10 and output a voltage signal.

The display panel 10 includes a front glass substrate 11,
The rear glass substrate 12 is arranged so as to face each other with a discharge space in between. The sustain electrodes 17X are formed on the front glass substrate 11 so as to extend across the discharge gap G.
(X ₁ , X ₂ , ... X _n ), scan electrode 17Y (Y ₁ ,
There are provided n pairs of electrode pairs 17 made of Y ₂ , ... Y _n ). A bus electrode 18 made of Al (aluminum) or the like is integrally provided on one side edge of the sustain electrode 17X and the scan electrode 17Y to reduce resistance. Also,
Here, the discharge gap G between the sustain electrode 17X and the scan electrode 17Y is less than 50 μm, preferably 20 μm or less. Therefore, the sustain discharge is more likely to occur than usual.

A dielectric layer 19 and a protective layer 20 are sequentially provided on the electrode pair 17. Normally, the dielectric layer is formed by applying a glass paste to a thickness of about 30 μm by a screen printing method. The dielectric layer 19 is formed by sputtering silicon oxide, vacuum deposition, ion plating or CVD (Chemical Vapor Deposition). ) Or the like to form a thin film having a uniform thickness of, for example, about 6 μm. The sufficiently thin dielectric layer 19 has a large capacitance, increases the amount of accumulated charge, and contributes to a reduction in driving voltage.

On the other hand, on the rear glass substrate 12, address electrodes 13 (A ₁ , A ₂ , ...
_-Am ) are arranged in parallel. A dielectric layer 14 and a partition wall 15 for partitioning the discharge space into each address electrode 13 are sequentially provided thereon. A phosphor 16 is provided between the partition walls 15.

Front glass substrate 1 having such a structure
1 and the rear glass substrate 12 are electrode pairs 17 (17X, 17
Y) and the address electrode 13 are aligned so that their extending directions are orthogonal to each other to form an n × m matrix having pixels at each intersection. FIG. 1 shows a state where such an electrode structure is viewed from the display surface side.
The X and scan electrodes 17Y are electrically connected to the sustain driver 21, and the address electrodes 13 are electrically connected to the data driver 22. Further, the substrates 11 and 12 are filled with a discharge gas in the discharge space and hermetically sealed at the peripheral edges. Here, Xe alone or Xe-containing gas is used as the discharge gas, and the pressure thereof is set to 5 kPa or more and 70 kPa or less. The Xe concentration of the Xe-containing gas is preferably 30% or more and less than 100%, which is high in order to improve brightness.

Next, the driving method according to the present embodiment will be described. Here, it is assumed that gradation control is performed by the subfield method, and the basic operations of reset, address, and sustain in each subfield are performed as usual.

FIGS. 3A to 3C are timing charts showing drive voltage waveforms (for one subfield) according to the drive method of the present embodiment, and FIGS. 4A and 4B are
The drive voltage waveform in the sustain period is enlarged and shown.

First, reset discharge is performed as usual.
Positive and negative pulses are simultaneously applied from the sustain driver 21 to all the sustain electrodes 17X and the scan electrodes 17Y,
Discharge between each electrode pair 17. As a result, either the state where the surface of the protective layer 20 in all the pixel regions is charged by the charged particles (wall charges are formed) or the state where the charges are erased from all the pixel regions is uniformly formed. .

Next, addressing is performed as usual. That is, from the sustain driver 21 to the scan electrode 1
The scan pulse is applied to 7Y, and at the same time, in synchronization with the scan timing from the data driver 22 to the address electrode
A data pulse is applied to 3. The data pulse is based on an ON / OFF signal generated from video data, and is controlled so as to be output to an ON display pixel when writing data and to an OFF display pixel when erasing data. . The value of each pulse is set so that the address discharge is generated by exceeding the discharge start voltage only when a voltage is applied to both electrodes of the scan electrode 17Y and the address electrode 13, and as a result, the pixel region to emit light is emitted. Wall charges are selectively formed on the.

Next, sustain discharge is performed. That is,
Sustain pulses are continuously applied alternately from the sustain driver 21 to all the sustain electrodes 17X and the scan electrodes 17Y in accordance with the light emission period. As a result, discharge is continuously generated between the electrode pair 17 of the pixel in which the wall charge is formed, and the light emission display of the selected pixel is performed. Each sustain pulse is referred to as a first pulse, a second pulse, a third pulse, ...

Here, first, as the first pulse, the sustain pulse 31 that rises sharply at the rising time t ₀ is
It is applied to the scanning electrode 17Y. It is preferable that the sustain pulse 31 rise as steeply as possible, and the rising time t ₀ is, for example, 200 ns or less, and further 100 ns.
It is set below. This allows the discharge to start earlier. Usually, in the first discharge, a relatively large discharge delay occurs due to less priming, but the discharge delay time is shortened here.

Subsequently, the sustain pulse 32 which rises at a rising time t ₁ (t ₁ > t ₀ ) longer than the sustain pulse 31 is alternately applied to the electrode pair 17 to sustain the discharge.
The value of the rise time t ₁ is set appropriately according to the conditions such as the discharge gas pressure in the display panel and the driving conditions.
The discharge delay time is set to be extended to the extent that electric power can be sufficiently recovered. Specifically, the discharge delay time is set to 80n.
It is preferable to set s or more so that the reactive current flowing at the time of pulse application is separated from the discharge current contributing to the discharge. As a result, the sustain pulse of the second pulse and thereafter is gently raised, and the concentration of current on the electrode pair 17 is reduced. In addition, the discharge delay time is adjusted to a length that allows sufficient power recovery.

As described above, in the present embodiment, the first
As the pulse, the sustain pulse 31 that sharply rises is applied to the scan electrode 17Y, and subsequently, the sustain pulse 32 that gradually rises more slowly than the sustain pulse 31 is alternately applied to the electrode pair 17 to generate the sustain discharge. Therefore, the unnecessarily long discharge delay time in the first discharge is shortened, and the discharge delay time in the subsequent discharge is adjusted to a length that can sufficiently recover the power, and the discharge state is controlled. Therefore, the sustain discharge can be stably performed, and the power consumption can be reduced by sufficiently collecting the power. Further, since the sustain pulse 32 of the second pulse or less is gradually raised, the deterioration of the display panel 10 due to the concentration of current and the load on the drive circuit are reduced.

In this embodiment, since the narrow gap type plasma display device is driven, the structure is more likely to cause the discharge between the electrode pair 17 than the conventional type,
Such discharge control has a more remarkable effect.

(Modification) FIGS. 5A and 5B are timing charts showing the driving method according to the modification of the first embodiment, and show the drive voltage waveforms during the sustain period. That is, the reset period and the address period are driven as in the first embodiment.

In this modification, during the sustain period,
The sustain pulse 31 is applied not only to the first pulse but also to the second pulse. As described above, priming cannot be expected at the time of applying the first pulse, but depending on the period before the sustain period, during which no discharge has occurred, even when the second pulse is applied, charged particles and the like have not been sufficiently supplied. There is a risk. Therefore, the second pulse has a waveform similar to that of the first pulse so that the discharge is intentionally started. As a result, the discharge delay time at the initial stage of sustain discharge is appropriately controlled. Note that this modified example is also applicable to the following embodiments.

[Second Embodiment] FIGS. 6A and 6B.
[FIG. 8] is a timing chart showing a driving method according to the second embodiment, showing a driving voltage waveform in a sustain period. In the following embodiments, the narrow gap type plasma display device similar to that in the first embodiment is driven, and therefore the same reference numerals are used for the respective constituent elements and the description thereof will be omitted as appropriate. Further, also in the driving method, description of the same parts as those in the first embodiment will be omitted.

Here, in the sustain period, the first
As a pulse, a sustain pulse 31 that rises steeply to the scan electrode 17Y is applied, and then sustain pulses 32a, 32 having a plurality of waveforms that rise more gently than the sustain pulse 31 are applied.
, b, 32c, ... are combined and sequentially applied to each of the electrode pairs 17. These sustain pulses 32a, 32b,
32c, ... are rise times t _1a ,
The pulses are different from t _1b , t _1c , ... And have rise times longer than the sustain pulse 31 (t ₀ <t _1a , t _1b , t _1c , ...).

Further, sustain pulses 32a, 32b, 32
It is preferable that c, ... Are set as predetermined n types of pulses and are applied in combination such that the types of pulses are different before and after, for example, these are repeated in order. Further, the types of applied pulses may all be different during the sustain period. Further, here, the type of pulse is changed for each of the electrodes 17X and 17Y, but the pulse type is changed according to the application order of the first pulse, the second pulse, the third pulse, .... You may

By thus changing the rise time of the sustain pulse in time series, the priming effect can be changed for each discharge. This prevents the discharge from always occurring in the same portion of the electrodes 17X and 17Y.

As described above, in the present embodiment, the second
Since the pulses below the pulse are the sustain pulses 32a, 32b, 32c, ...
It is possible to prevent the protective layer 19 on the electrode 17 from being locally deteriorated by shifting the portion of X and 17Y that causes a discharge, at each discharge. Therefore, the variation of the discharge starting voltage caused by this is suppressed, and the reliability of the device can be improved. The other effects are similar to those of the first embodiment.

(Modification) FIGS. 7A and 7B are timing charts showing the driving method according to the modification of the second embodiment, showing the drive voltage waveform during the sustain period. In the present modification, the sustain pulses 32a, 32 having no correlation with the rise time of the second pulse and the following pulses are provided.
b, 32c, 32d, 32e, ... Are applied. That is, in the second pulse and thereafter, the rising time is randomly changed to generate the sustain pulse. The sustain pulses 32a, 32b, 32c, 32
As with the second embodiment, d, 32e, ... Are set so that the rising time is longer than that of the sustain pulse 31. In this case, it is not necessary to consider the combination of pulse types, and it is possible to prevent the protective layer 19 from locally deteriorating more easily by shifting the discharge portions of the electrodes 17X and 17Y at each discharge.

The present invention is not limited to the above-mentioned embodiments and modifications, and various modifications can be made. For example, in the above embodiment, the narrow gap type plasma display device having a sustain discharge gap of less than 50 μm has been described, but the present invention can be applied to a conventional plasma display device having a sustain discharge gap of about 100 μm. Needless to say, it is suitably applied especially when the Xe concentration of the discharge gas is high. Even in that case, the same effect as that of the above-described embodiment can be exhibited.

[0046]

As described above, according to the driving method of the plasma display device of any one of claims 1 to 12, at least one of the electrode pairs rises steeply at the rise time t ₀ . 1 sustain pulse is applied,
Subsequently, a second sustain pulse that rises with a rise time t ₁ (t ₁ > t ₀ ) longer than the first sustain pulse is alternately applied to the electrode pair continuously according to the light emission period, and the discharge is performed. Since the light emission display is performed by continuously performing the discharge, the first sustain pulse shortens the unnecessarily long discharge delay time in the first discharge, and the second sustain pulse shortens the discharge delay time in the subsequent discharge. Is adjusted to a length that allows sufficient power recovery, and the discharge state is controlled. Therefore, the sustain discharge can be stably performed, and the power consumption can be reduced by sufficiently collecting the power. In particular, when driving a narrow gap type plasma display device, the structure is more likely to cause discharge between the electrode pairs than the conventional type, and the discharge delay tends to be shorter, so a great effect can be expected.

According to the driving method of the plasma display device of any one of claims 2 to 4, the second method is provided.
Since multiple types of pulses with different rise times are combined in time series and applied as the sustaining pulse of, the part of the electrode where discharge occurs is shifted at each discharge, and discharge always occurs in the same part. Is avoided. Therefore, local deterioration of the protective layer on the electrodes is suppressed, fluctuations in the discharge starting voltage, etc. are prevented, and the reliability of the device can be improved.
