Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to an AC plasma display panel and a method of driving the same.

[0002]

2. Description of the Related Art FIG. 11 is a sectional view of a main part of a conventional AC surface discharge type plasma display panel (hereinafter referred to as a conventional panel). FIG. 11B is a sectional view taken along line AA of FIG.

As shown in FIG. 11, in a conventional panel 1, a front substrate 3 made of glass and a rear substrate 4 made of glass are arranged opposite to each other with a discharge space 2 interposed therebetween.
A gas that emits ultraviolet rays by discharge, such as neon and xenon, is sealed in the gap. Front substrate 3
On the upper side, an electrode group including a pair of strip-shaped scan electrodes 7 and sustain electrodes 8 covered with a dielectric layer 5 and a protective film 6 is arranged in parallel with each other. The scanning electrode 7 and the sustaining electrode 8 are composed of transparent electrodes 7a, 8a and metal busbars 7b, 8b for increasing conductivity, respectively.

On the rear substrate 4, strip-shaped data electrodes 9 are arranged in parallel with each other in a direction orthogonal to the scanning electrodes 7 and the sustaining electrodes 8, and these data electrodes 9 are separated from each other.
In addition, a strip-shaped partition 10 for forming the discharge space 2 is provided between the data electrodes 9. Further, a phosphor layer 11 is formed from above the data electrode 9 to the side surface of the partition wall 10. Further, the discharge space 2 is filled with a mixed gas of xenon (Xe) and at least one of helium (He), neon (Ne), and argon (Ar).

In such a conventional panel 1, the distance dp between the scan electrode 7 and the sustain electrode 8 (hereinafter referred to as a sustain discharge gap) is set close to a value at which a minimum discharge voltage determined by Paschen's law is obtained. ing. This is to lower the external sustain voltage VSUS applied between the scan electrode 7 and the sustain electrode 8 during the sustain period. That is, the discharge starting voltage between scan electrode 7 and sustain electrode 8 is set to V
When the sum of the wall voltage of the dielectric layer 5 on the scan electrode 7 and the wall voltage of the dielectric layer 5 on the sustain electrode 8 is VwSS, the voltage applied to the discharge space is VSUS + VwSS. In order to maintain the discharge between the electrode 7 and the sustain electrode 8, VfSS <VSUS + VwSS must be satisfied. By designing the panel so that VfSS is minimized, discharge can be maintained at a lower external sustain voltage VSUS. The lower the external sustain voltage VSUS is, the easier the circuit design is, and the loss due to the reactive power can be reduced.

At present, in the panel being manufactured, the total pressure of the filled gas is about 50 to 60 kPa, and the sustain discharge gap dp
Is 80 to 100 μm, VSUS becomes extremely small,
SUS = 180 to 200 V is obtained. In that case,
It is known that the luminous efficiency becomes highest when the partial pressure of xenon gas is 5 to 10%.

[0007]

However, the conventional panel has a problem that the luminous efficiency is significantly lower than that of a display device such as a CRT. For example, in the above-described panel having the sustain discharge gap dp of 80 to 100 μm, the luminous efficiency is about 1 lm / W, which is about one fifth of the CRT.

It is generally known that the longer the distance between the electrodes causing discharge, the higher the luminous efficiency. However, the longer the distance between the scan electrode 7 and the sustain electrode 8, the higher the discharge starting voltage V
The fSS also rises sharply according to the Paschen curve, making it difficult to drive, and there is a problem that a phenomenon of causing adjacent cells to be erroneously discharged (hereinafter referred to as crosstalk) is likely to occur.

When the distance between the scanning electrode 7 and the sustaining electrode 8 is increased while keeping the cell pitch constant, the scanning electrode 7 is connected to the sustaining electrode 8 of the adjacent cell, and the sustaining electrode 8 is turned in the opposite direction. Is closer to the scan electrode 7 of the adjacent cell, and the scan electrode 7 and the sustain electrode 8 which are the original discharge display space
This is because the discharge start voltage at the electrode between adjacent cells becomes closer to the discharge start voltage.

[0010] Of course, this phenomenon means that a discharge occurs in a cell other than the writing cell by the video signal, and the display quality of the video on the panel is remarkably deteriorated.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and prevents the occurrence of crosstalk without greatly increasing the applied voltage for sustaining discharge even when the sustain discharge gap is lengthened. It is an object of the present invention to provide an AC type plasma display panel and a driving method thereof.

[0012]

According to the present invention, there is provided an AC type plasma display panel comprising: a first substrate having a first electrode and a second electrode covered with a dielectric layer formed substantially in parallel with each other; The third direction perpendicular to the electrode and the second electrode
An electrode is formed, and a partition parallel to the third electrode and a second substrate alternately formed with the third electrode are disposed opposite to each other across a discharge space, and a phosphor is provided on a wall surface between the partitions. A layer is formed, a distance between the first electrode and the second electrode is set to be greater than a height of the discharge space, and is defined by one third electrode and a pair of the first electrode and the second electrode. The discharge display space to be formed is one display cell, and the display cell is orthogonal to the third electrode in a space defined by the partition and the first dielectric layer and the second dielectric layer. In the projection cross-section in the direction of the third electrode, the projection cross-section between the display cells adjacent to each other in the third electrode direction is smaller than the projection cross-section in the display cell.

With this configuration, a display discharge with high luminous efficiency can be formed without increasing the discharge voltage, and
Crosstalk can be prevented.

Further, in the driving method of an AC type plasma display panel according to the present invention, the discharge space between the first electrode and the third electrode is a first opposed discharge space, and the second electrode and the third electrode are connected to each other. In the address period, a positive voltage is applied to the second electrode and the third voltage is applied to the third electrode during the address period.
A data pulse is applied to the electrode, and during the sustain period, a voltage is applied to the second electrode such that a discharge with the second electrode as the cathode side starts in the second opposed discharge space, and a voltage is applied to the second electrode. On the other hand, a positive voltage is applied to the first electrode.

Further, by making the space between the discharge cells narrower than the first discharge space and the second discharge space, crosstalk is prevented.

In addition to this configuration, light absorption occurs on the first substrate in a region between the discharge cells, which is a space not contributing to discharge between the discharge cells, and in a region between two adjacent pixels. A layer is formed.

With this configuration, it is possible to reduce the reflectance of the panel with respect to external light without blocking most of the light emitted from the discharge space.

According to this method, a stable display discharge can be formed in a long gap discharge space without increasing the discharge voltage.

[0019]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a sectional view showing a main part of an AC type plasma display panel (hereinafter, referred to as a panel) according to a first embodiment of the present invention. 2 is a sectional view taken along line BB of FIG. 1, and FIG. 3 is a sectional view taken along line CC of FIG.

As shown in FIGS. 1 to 3, a panel 12 according to an embodiment of the present invention has a front substrate 3 made of glass and a rear substrate 4 made of glass, which are arranged to face each other with a discharge space 2a interposed therebetween. I have. On the front substrate 3, a plurality of electrode pairs each including a first electrode 13 and a second electrode 14 in a band shape covered with the dielectric layer 5 are arranged. A protective film 6 is formed on the dielectric layer 5, and a material having a high secondary electron emission coefficient such as magnesium oxide (MgO) is used for the protective film 6.

On the back substrate 4, a plurality of strip-shaped third electrodes 1 are arranged in a direction orthogonal to the first electrodes 13 and the second electrodes 14.
5 are arranged, and a strip-shaped partition wall 10 for isolating each third electrode 15 and forming a discharge space 2a is formed as a third partition.
It is provided between the electrodes 15.

A horizontal rib 18 serving as an auxiliary partition is provided in a direction perpendicular to the partition 10 between each pixel in the discharge space 2a as the display cell and the display space adjacent thereto. However, the auxiliary partition 18 is lower than the height of the partition 10 because a space for exhausting and sealing the gas in the cell is required. Furthermore, between the partition walls 10, the third electrode 1
The phosphor layer 11 is formed so as to cover the side surfaces of the partition wall 5 and the partition wall 10 and the auxiliary partition wall 18. The discharge space 2a is filled with a mixed gas of xenon (Xe) and at least one of helium (He), neon (Ne), and argon (Ar).

The panel 12 is configured to view an image display from the front substrate 3 side, which is the display surface side, and to display the discharge space 2.
a, the fluorescent layer 1
1 is used to generate visible light and use it for display light emission.

In the panel 12 of the present embodiment, the gap between the first electrode 13 and the second electrode 14 is a gap dss, and the surface of the phosphor layer 11 and the surface of the protective film 6 on the center line of the third electrode 15. (Hereinafter referred to as the opposing discharge gap), that is, when the height of the discharge space 2a on the center line of the third electrode 15 is dsa, dss> dsa
Is set. The first opposed discharge space is the first electrode 1.
The discharge space between the third electrode 15 and the third electrode 15 and the second opposed discharge space indicate the discharge space between the second electrode 14 and the third electrode 15. Table 1 shows an example of panel design parameters according to the present embodiment.

[0026]

[Table 1]

The distance between the electrodes performing the sustain discharge in the conventional surface discharge type panel, that is, the distance between the scanning electrode 7 and the sustain electrode 8 is 80 to 100 μm, whereas the gap of the panel of the present embodiment is 80 μm. dss is set to 400 μm, which is about five times as large as the conventional value. Therefore, when the panel of the present embodiment is driven by the conventional driving method, the voltage VfSS for starting the sustain discharge becomes extremely high. Therefore, in the present embodiment, by using the third electrode 15, Vf
The sustain discharge is performed by lowering the SS, and this sustain discharge is not a conventional surface discharge but rather a counter discharge.

Next, a method for displaying image data on the panel 12 of the present embodiment will be described.

As a method of driving the panel of this embodiment, one field period is divided into a plurality of subfields having a weight of a light emission period based on a binary system, and gradation display is performed by a combination of subfields to emit light. Do.
Each subfield includes an initialization period, an address period, and a sustain period.

In order to display image data, different signal waveforms are applied to each electrode during the initialization period, the address period, and the sustain period. During the initialization period, for example,
A pulse voltage of a positive polarity is applied to all the scan electrodes 7 with respect to the sustain electrodes 8 and the data electrodes 9 to accumulate wall charges on the protective film 6 and the phosphor layer 11.

In the address period, scanning is performed by sequentially applying a negative pulse to all the scanning electrodes 7. When there is display data, when a positive data pulse is applied to the data electrode 9 while the scan electrode 7 is being scanned, discharge occurs between the scan electrode 7 and the data electrode 9,
Wall charges are formed on the surface of the protective film 6 on the scanning electrode 7.

In the subsequent sustain period, a sustain pulse having an amplitude VSUS is applied to the first electrode 13 and the second electrode 14 alternately. The sustain pulse is applied to the second counter discharge space at time t3.
It is applied in such a phase that a discharge with the electrode 14 on the cathode side starts. At this time, since a positive voltage is applied to the first electrode 13 with respect to the second electrode 14, the discharge generated in the second opposed discharge space extends in the direction of the first electrode 13, and time At t4, a discharge is also formed in the first opposed discharge space. As a result, the polarity of the charge stored in the protective film 6 on the first electrode 13 and the second electrode 14 is reversed.

In the subsequent sustain period, the above operation is alternately repeated, and discharge light emission is performed a number of times corresponding to the weight of the subfield.

Next, a mechanism in which the discharge started in one opposed discharge space extends in the direction of the other opposed discharge space will be described in detail with reference to FIGS. 5 and 6, taking a sustain period as an example.

FIGS. 5 and 6 show the state of the applied voltage, the wall charge, and the discharge plasma during the sustain period for the simplified cross-sectional view of the panel of the present embodiment shown in FIG. The protective film 6 is omitted.

FIG. 5A shows the time t3 of the sustain period (FIG. 4A).
2) shows the wall charges and the applied voltage. At time t3, the external sustain voltage Vsus is applied to the first electrode 13,
The second electrode 14 is grounded. In the address period, since negative wall charges are accumulated on the dielectric layer 5 on the second electrode 14, a voltage having the second electrode 14 as the negative electrode is applied to the second opposed discharge space, and the discharge is started. Start. Although a voltage of about Vsus is applied to the first opposed discharge space, the phosphor layer 11
The discharge cannot be started because of the polarity of the cathode. In addition,
Positive wall charges are accumulated on the phosphor layer 11 on the third electrode 15. This is because a large positive voltage was applied to the second electrode 14 during the address period, while the third electrode 15 having a lower potential attracted positive charges.

FIG. 5B shows a state in which discharge has started in the second opposed discharge space. When the discharge starts in the second opposed discharge space, a large amount of positive charges and negative charges are generated, and are attracted toward the second electrode 14 and the third electrode 15, respectively, to form wall charges. The wall voltage generated by the wall charge acts to cancel the voltage applied to the second opposed discharge space and stop the discharge. Comparing the dielectric layer 5 on the second electrode 14 and the phosphor layer 11 on the third electrode 15, the latter has a smaller dielectric constant, so that the accumulation of wall charges proceeds faster on the third electrode 15 side. .
As a result, the anode end of the discharge moves in search of the phosphor layer surface to which the negative charge can flow. The moving direction is the first electrode 13 to which the positive external sustain voltage Vsus is applied.
Direction.

FIG. 5C shows a state in which the anode end of the discharge is moving. The anode end of the discharge extends toward the first electrode 13 while canceling out the positive charges accumulated on the phosphor layer 11.

When the anode end of the discharge approaches the first opposed discharge space, the amount of space charge in the first opposed discharge space increases, and the discharge starting voltage decreases. The time t4 (see FIG. 4) indicates a time during which the discharge using the phosphor layer 11 as a cathode can be started in the first opposed discharge space as a result of the decrease in the discharge start voltage.

FIG. 6A shows a state where the discharge has started in the first opposed discharge space at time t4. At this time, the first
A positive column discharge is formed so as to connect the opposing discharge space to the second opposing discharge space, and a large amount of ultraviolet light is emitted.

FIG. 6 (b) shows the second discharge at the beginning of discharge.
This shows a state in which wall charges are accumulated on the electrode 14 and the third electrode 15 opposed thereto, and the voltage applied to the second opposed discharge space is almost zero. At this time, the discharge on the second opposed discharge space side is extinguished, but a part of the positive column still remains on the first opposed discharge space side. This discharge forms negative wall charges on the dielectric layer 5 on the first electrode 13 and positive wall charges on the phosphor layer 11 on the third electrode 15 in the first opposed discharge space. . As a result, the first occurrence of the sustain discharge
It is stored as the wall charge of the opposed discharge space.

FIG. 6C shows a state where the discharge is stopped as a result of accumulation of wall charges on the dielectric layer 5 and the phosphor layer 11. Negative charges are accumulated in the dielectric layer 5 on the first electrode 13 to which the positive external sustain voltage Vsus is applied, and the second electrode 1
Positive charges are accumulated in the dielectric layer 5 and the phosphor layer 11 on the top 4. This is obtained by reversing the distribution of wall charges at the time t3 for the first electrode 13 and the second electrode 14.

Therefore, in the state of FIG. 6C, when the positive external sustain voltage Vsus is applied to the second electrode 14 and the first electrode 13 is grounded (time t5 in FIG. 4), the first The first electrode 13 and the second electrode 14 are switched, and the same sustain discharge can be repeated.

Here, the previous discharge state is stored as wall charges in the opposite discharge space on the side where the anode end of the discharge has reached. For example, if a certain discharge reaches the second opposed discharge space and ends, the next discharge starts in the second opposed discharge space and is completed by reaching the first opposed discharge space. At the end of the discharge, the wall voltage in the opposite discharge space on the side where the discharge has started is almost completely erased as shown in FIG. 5A or FIG. 6C, and the previous discharge state is not stored.

As described above, in the present embodiment, the discharge generated in the first opposing discharge space and the discharge generated in the second opposing discharge space extend to the other opposing discharge space, thereby maintaining the sustain discharge. Do. Such a discharge is not a conventional surface discharge, but rather a counter discharge.

The time td from the time when the sustain discharge voltage of the first or second electrode decreases to the time when the other sustain discharge voltage rises is arbitrary, and the above operation is performed within a range of ± several hundred ns. Has been confirmed. td is negative,
That is, the sustain discharge voltages of the first and second electrodes are both Vsus.
If there is a period of time when the potential is reached, the discharges in the first opposed discharge space and the second opposed discharge space start almost simultaneously. On the other hand, when td is positive, that is, when there is a period in which the sustain voltages of the first and second electrodes are both at the ground potential, the discharge of the second opposed discharge space is considerably delayed after the discharge of the first opposed discharge space is started. Discharge may start. In the latter case, two light emission may be observed during the half-cycle sustain discharge, but it is essentially the same as the former discharge mode. However,
It can be said that the latter is a discharge mode having a stronger opposing discharge characteristic.

In a discharge cell having a long gap dss, which is the distance between the first electrode 13 and the second electrode 14, a so-called positive column discharge can be formed to obtain high luminous efficiency. However, since the gap dss is increased to 400 μm, the first electrode 13 of a certain discharge cell among the discharge cells arranged in the direction parallel to the partition wall and the first electrode 13
And the second electrode 14 which is adjacent to and belongs to the adjacent discharge cell
Is 1080-430-100 × 2 = 450 μm
And there is no large difference from the gap dss.
Therefore, the direction from the first electrode to the second electrode between adjacent cells,
Or, the so-called crosstalk in which the positive column extends in the opposite direction is liable to occur.

However, in this embodiment, the cross talk is prevented by providing the auxiliary partition 18 between the discharge cells. This is because, when the discharge gap is constant, the permittivity is higher than that of the sealed gas, but by entering the gap space, the effective electric field applied to the gas is reduced. The fact that the discharge becomes difficult to suppress the increase in the effective discharge start voltage VfSS is used. Further, by applying a phosphor to the wall surface of the auxiliary partition wall 18, the area of the phosphor can be increased and the luminous efficiency of the panel can be increased.

As described above, in this embodiment, since the sustain discharge is performed in the opposed discharge space, the gap dss is set to 400 μm.
Despite having been increased to m, it is possible to suppress an increase in the discharge maintaining voltage. Further, crosstalk is prevented by providing an auxiliary partition between adjacent cells. As a result, in this panel, a luminous efficiency of 2 lm / W and a stable discharge were obtained. Since the luminous efficiency of the conventional panel is 1 lm / W or less, the luminous efficiency of the panel of the present embodiment is more than twice as large as that of the conventional panel.

As described above, in the present embodiment, the gap between the first electrode 13 and the second electrode 14 can be increased, so that the luminous efficiency is high and the display quality is not deteriorated due to crosstalk. The suppressed AC type plasma display panel can be obtained.

Next, a second embodiment of the present invention will be described with reference to FIG. FIG. 7 is a sectional view of a main part of a panel according to a second embodiment of the present invention. As shown in FIG. 7, in the panel 17 of the second embodiment, the width of the barrier ribs 10 is changed between the discharge space and the adjacent cells to increase the width between the adjacent cells, thereby effectively increasing the cross section between the adjacent cells. The space is made narrower than the discharge space, and crosstalk is prevented similarly to the panel of the first embodiment. Other structures and driving methods of the panel are the same as those of the panel of the first embodiment shown in FIGS.

Next, a third embodiment of the present invention will be described with reference to FIG. FIG. 8 is a sectional view of a main part of a panel according to a third embodiment of the present invention. As shown in FIG. 8, in the panel 17 of the third embodiment, the thickness of the first dielectric layer 5 is changed between the discharge space and the adjacent cells to increase the thickness between the adjacent cells, thereby increasing the effective thickness. The structure is such that the cross-sectional space between adjacent cells is narrower than the discharge space, and crosstalk is prevented, similarly to the panel of the first embodiment. Other structures and driving methods of the panel are the same as those of the panel of the first embodiment shown in FIGS.

Next, a fourth embodiment of the present invention will be described with reference to FIG. FIG. 9 is a sectional view of a main part of a panel according to a third embodiment of the present invention.

As shown in FIG. 9, in the panel 17 of the third embodiment, the thickness of the second dielectric layer 5a is changed between the discharge space and the adjacent cells so as to increase the thickness between the adjacent cells. And
The structure is such that the cross-sectional space between the adjacent cells is effectively made smaller than the discharge space, and crosstalk is prevented similarly to the panel of the first embodiment. Other structures and driving methods of the panel are the same as those of the panel of the first embodiment shown in FIGS.

Next, a fifth embodiment of the present invention will be described with reference to FIG. FIG. 10 is a sectional view of a main part of a panel according to a fifth embodiment of the present invention.

As shown in FIG. 10, in the panel 17 according to the fifth embodiment, the thickness of the phosphor layer covering the second dielectric layer 5a is changed between the discharge space and the adjacent cells to change the thickness between the adjacent cells. Thus, the cross-sectional space between adjacent cells is effectively made narrower than the discharge space, and crosstalk is prevented similarly to the panel of the first embodiment. Other structures and driving methods of the panel are the same as those of the panel of the first embodiment shown in FIGS.

As described above, in the present embodiment, the positive pole is generated by increasing the gap between the first and second electrodes, and crosstalk is prevented by reducing the cross-sectional space between adjacent cells. An AC plasma display panel can be obtained.

In each of the above embodiments, an AC type plasma display panel which performs so-called address-sustain separation type driving in which an address period and a sustain period are separated from each other has been described. A similar effect can be obtained in a plasma display panel. The applied voltage waveforms in the initialization period and the address period do not need to be the same as those in the present embodiment, and may be any as long as wall charges are selectively formed according to the presence or absence of image data.

The positive column here refers to a filamentary discharge generally generated in a discharge space having a long distance between electrodes.

[0060]

As described above, according to the present invention, the gap between the first electrode and the second electrode arranged in parallel to each other is set to be larger than the facing discharge gap, and the space between adjacent cells is narrowed. In an AC type plasma display panel,
By extending the discharge generated in one opposing discharge space to the other opposing discharge space and forming a positive column discharge, the discharge voltage was not increased, crosstalk was prevented, and luminous efficiency and display quality were improved. An AC plasma display panel and a driving method thereof can be provided.
