[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an AC type plasma display device used for displaying images on a television receiver, an advertisement display panel, and the like.

It is arranged. The discharge space 12 is filled with one or a mixture of helium, neon, argon, and xenon as a discharge gas.

That is, in the panel having such a structure, one discharge cell is formed in a region corresponding to one intersection of the display electrode including the pair of scan electrodes 4 and the sustain electrode 5 and the data electrode 9. I have.

Next, the operation of the panel will be described. First, as shown in FIG. 10, the electrode arrangement of this panel has a matrix configuration composed of M rows × N columns of discharge cells, and M rows of scan electrodes SCN1 to SCNM and sustain electrodes SUS1 to SUSM are arranged in the row direction. The data electrodes D1 to DN of N columns are arranged in the column direction. FIG. 11 shows a timing chart of a driving method of the AC type plasma display device used for this panel.

As shown in FIGS. 10 and 11, during the writing period, all the sustain electrodes SUS1 to SUSM are set to 0.
(V), a positive write pulse voltage + Vw (V) is applied to predetermined data electrodes D1 to DN corresponding to the discharge cells to be displayed in the first row, and a negative write pulse voltage is applied to the scan electrodes SCN1 in the first row. When a scanning pulse voltage -Vs (V) is applied to each of the scanning electrodes, predetermined data electrodes D1 to DN and scanning electrodes S1 in the first row are applied.
Write discharge occurs at the intersection with CN1.

Next, a positive write pulse voltage + Vw (V) is applied to predetermined data electrodes D1 to DN corresponding to the discharge cells to be displayed in the second row, and a negative scan pulse is applied to the scan electrodes SCN2 in the second row. When voltage -Vs (V) is applied to each,
The predetermined data electrodes D1 to DN and the scan electrodes SCN of the second row
Write discharge occurs at the intersection with 2. The same operation as described above is sequentially performed. Finally, a positive write pulse voltage + Vw (V) is applied to predetermined data electrodes D1 to DN corresponding to the discharge cells to be displayed on the Mth row, and the Mth row is scanned. Electrode S
When a negative scan pulse voltage -Vs (V) is applied to the CNM, a write discharge occurs at the intersection of the predetermined data electrodes D1 to DN and the Mth row scan electrode SCNM.

In the next sustain period, all scan electrodes SCN
1 to SCNM are temporarily held at 0 (V), and a negative sustain pulse voltage −Vm is applied to all the sustain electrodes SUS1 to SUSM.
When (V) is applied, the scan electrodes SCN1 to SCNM and the sustain electrode SUS at the intersection where the write discharge has occurred are performed.
Sustain discharge occurs between 1 and SUSM.

Next, a negative sustain pulse voltage -Vm (V) is alternately applied to all the scan electrodes SCN1 to SCNM and all the sustain electrodes SUS1 to SUSM, so that the sustain discharge is continued in the discharge cells to be displayed. Happen. Panel display is performed by the light emission of the sustain discharge.

In the next erase period, all the scan electrodes S

When (V) is applied, an erasing discharge occurs to stop the discharge. With the above operation, one screen of the AC type plasma display device is displayed.

Here, the stability and luminance of the sustain discharge in the above description will be described.

FIG. 12 is a sectional view taken along line AA 'of FIG. 9, and FIG. 13 is a sectional view taken along line BB' of FIG. This figure shows the dimensional relationship between scan electrode 4 and sustain electrode 5 and sustain discharge represented by scan electrode SCNi and sustain electrode SUSi in the i-th row and scan electrode SCNi + 1 and sustain electrode SUSi + 1 in the i + 1-th row. Is shown. As shown by the solid line arrows in FIG. 12, the sustain discharge occurs between scan electrode SCNi and sustain electrode SUSi in the i-th row, or i.
Since the discharge is between the scan electrode SCNi + 1 in the + 1st row and the sustain electrode SUSi + 1, that is, the discharge between the scan electrode 4 and the sustain electrode 5 in the same row, these electrode gaps G are narrowed. Further, sustain electrodes SUSi indicated by dotted arrows in FIG.
Since the discharge between +1 and scan electrode SCNi is erroneous discharge Y which is not the original sustain discharge, the discharge between sustain electrode SUSi + 1 and scan electrode SCNi is performed so that erroneous discharge Y does not occur. The distance D is sufficiently wide.

The scanning electrode 4 and the sustaining electrode 5 are composed of transparent electrodes 4a, 5a and buses 4b, 5b of silver or the like, and the buses 4b, 5b are opaque. Therefore, as shown in the luminance distribution characteristics of FIG. 14, the luminance decreases at the positions of the buses 4b and 5b. As a countermeasure against this, the electric resistance of the buses 4b and 5b is made as low as possible, and
The reduction in luminance due to the line widths b and 5b is suppressed.

[0015]

However, in the structure of the conventional panel described above, when the number of rows M of the panel is increased in order to realize high definition in a panel of the same size, it is shown in FIG. As described above, the sustain electrode SUSi
When the number of rows M increases to a certain value or more, the electrode between the sustain electrode SUSi and the scan electrode SCNi + 1 is inevitably reduced. There is a problem that erroneous discharge Y shown by a dotted arrow occurs therebetween, and display on the panel is not performed normally.

In the case where high definition is to be realized,
From the viewpoint of the adhesive strength of the bus bars 4b, 5b to the transparent electrodes 4a, 5a, the bus bar 4 to the area of the transparent electrodes 4a, 5a
There is a problem that the ratio of the areas b and 5b increases, and the luminance distribution characteristics decrease at the positions of the buses 4b and 5b.

An object of the present invention is to provide a high-definition panel with high display quality in which erroneous discharge is prevented and luminance is reduced even if the structure of the display electrode pair is improved.

[0018]

In order to solve the above-mentioned problems, an AC-type plasma display device according to the present invention has a transparent electrode in which a plurality of rows of display electrodes are arranged so that a non-display portion is formed therebetween. A front-side substrate, and a rear-side substrate provided with a plurality of rows of data electrodes arranged in a direction orthogonal to the display electrodes so as to face each other so as to form a discharge space between the front-side substrate and the front-side substrate.

3 is a sectional view taken along line BB ′ of FIG.

As shown in FIGS. 1 to 3, on a front substrate 21 made of a transparent glass substrate or the like, a dielectric layer 22 and a protective film layer 23 cover a scan electrode 24 and a sustain electrode 25. A plurality of stripe-shaped display electrodes 26 paired with each other
Are arranged in parallel in a plurality of columns so that a non-display portion 27 is formed therebetween, and a light-shielding layer 28 is provided in the non-display portion 27 between adjacent display electrodes 26. Further, the scanning electrode 24 and the sustain electrode 25 are respectively
a and 25a, and buses 24b and 25b made of silver or the like, which are provided at the ends on the non-display portion side on the transparent electrodes 24a and 25a and are electrically connected to the ends. Generally, since the transparent electrodes 24a and 25a have a large electric resistance, the resistance of the scanning electrodes 24 and the sustain electrodes 25 as electrodes is reduced by forming the bus bars 24b and 25b with a low-resistance material such as silver.

A plurality of data electrodes 31 covered with an insulator layer 30 and arranged in a plurality of rows in a direction perpendicular to the display electrodes 26 are provided on a rear substrate 29 also made of a transparent glass substrate or the like. Insulator layer 30 between data electrodes 31
A plurality of partition walls 32 made of glass or the like are provided on the upper side in parallel with the data electrodes 31.

The rear substrate 29 and the front substrate 21
Is that the display electrode 26 composed of the scan electrode 24 and the sustain electrode 25 and the data electrode 31 are orthogonal to each other, and are arranged to face each other so that a discharge space 33 is formed therebetween. Then, in the discharge space 33, helium as a discharge gas,
One or a mixed gas of neon, argon, and xenon is sealed.

That is, in the panel having such a structure, one discharge cell is formed in a region corresponding to one intersection of the display electrode 26 including the pair of scan electrodes 24 and the sustain electrodes 25 and the data electrode 31. ing. A strip-shaped partition wall 32 disposed between the data electrodes 31 on the rear substrate 29 defines the discharge space 33 and defines a gap dimension H of the discharge space 33 in the thickness direction of the panel. .

In the present invention, the non-display portion 2 of the front substrate 21 is interposed between the partitions 32 on the rear substrate 29.
A barrier 35 having a width corresponding to the non-display portion 27 and forming a gap 34 with the front substrate 21 and preventing erroneous discharge between the display electrodes 26 is provided at a position facing the non-display portion 27. Provided.

Between the partition walls 32, red, red and black are applied to the side surfaces of the partition walls 32, the side surfaces of the barriers 35, and the surface of the insulating layer 28.
Each of the phosphors 36 emitting blue and green light is arranged in a striped manner in order via the partition 32, and a set of R, G,
One pixel is constituted by three discharge cells corresponding to the phosphor 36 of B.

Here, the gap 34 formed between the front substrate 21 and the barrier 35 has a function of allowing the discharge space 33 between the pair of adjacent display electrodes 26 to communicate with each other and allowing the discharge gas to flow therethrough. Has the function of preventing the erroneous discharge Y between the pair of display electrodes 26 adjacent to each other by setting the size of the display electrodes 26. That is, the front substrate 21 and the front substrate 2
A gap 34 is formed between the first and first barrier surfaces 32a, and a barrier surface 35a is provided in parallel with the front substrate surface 21a. Then, the height H of the partition wall 32, the height T of the barrier 35, and the height of the partition wall 32 on the substrate 29 on the rear side are determined.
The difference between the height H of the scan electrode 24 and the height T of the barrier 35 is δ, and a pair of the scan electrode 24 and the sustain electrode 2 adjacent via the non-display portion 27
Assuming that the distance from D is 5, the relationship is δ ≦ D / 3. In addition, a bus 24 b and a bus 2 between a pair of scanning electrodes 24 and sustain electrodes 25 adjacent to each other via the non-display portion 27.
The distance X between the generatrix crossing 5b is configured to be smaller than the width B of the barrier 35 in the longitudinal direction of the partition 32.

The electrode arrangement and timing chart of this panel are the same as those described in the conventional example shown in FIGS.

As described above, in the panel according to the embodiment of the present invention, the erroneous discharge between the adjacent display electrodes 26 is formed on the rear substrate 29 at a portion facing the non-display portion 27 of the front substrate 21. Since the barrier 35 is provided for prevention, even when the structure of the display electrode 26 has a high definition (a structure in which the size of the discharge cell is reduced), it is adjacent via the non-display portion 27 as compared with the related art. The distance D between the display electrodes 26 can be reduced without the erroneous discharge Y. As a result, the display electrode 26
And the light emitting area of each discharge cell is widened, and the luminance can be improved. In addition, since the erroneous discharge Y between the adjacent display electrodes 26 via the non-display portion 27 is prevented,
An image with high contrast can be displayed. Further, since the width W of the display electrode 26 can be increased as described above,
The display electrode 26 includes transparent electrodes 24a, 25a and a bus 24b,
25b, the transparent electrode 2 compared to the prior art
The ratio of the area of the buses 24b and 25b to the area of 4a and 25a is reduced, and the luminance can be improved.

The discharge space 33 between the adjacent display electrodes 26 is communicated by a gap 34.
It is possible to prevent erroneous discharge between the adjacent display electrodes 26 via the non-display portion 27 only by defining the size of the opening. Further, the front substrate 21 and the front substrate 2
Since the gap 34 is formed between the first and second barrier surfaces 35a, that is, the partition wall 32 and the barrier 35 can be provided on the rear substrate 29, the partition wall 32 and the barrier 35 are formed in one direction by, for example, sandblasting. Can be formed at the same time, and manufacturing is easy. In particular, since the barrier surface 35a facing the front substrate 21 is formed in parallel with the front substrate surface 21a, manufacture is easy as described above.

A bus 24b straddling the buses 24b, 25b between the adjacent display electrodes 26 via the non-display portion 27,
Since the distance X between the electrodes 25b is smaller than the width B of the barrier 35 in the longitudinal direction of the partition 32, the light emission generated by the discharge of the display electrode 26 is not blocked by the opaque buses 24b and 25b. , The display brightness can be improved as compared with the conventional panel.

Further, since the phosphor 36 is disposed on the side surface of the barrier 35, the phosphor 36 is disposed near the discharge of the display electrode 26.
Emits light, and as a result, the display luminance from the discharge cells can be further improved.

Next, an embodiment in which the effect of the present invention has been confirmed will be described.

(Embodiment 1) As a panel according to Embodiment 1 of the present invention shown in FIGS. 1, 3 and 4, 480 rows × 85
Using two rows of 42 inch panels, electrode gap G = 8
0 (μm), electrode width W of scanning electrode 24 and sustain electrode 25 = 370 (μm), distance between electrodes D = 260 (μm),
The width B of the barrier 35 = 260 (μm) and the height H of the partition 35 =
120 (μm), and the height T (μm) of the barrier was changed, that is, the relationship between the ratio P between the electrode distance D and the gap δ and the probability P at which the erroneous discharge Y occurred was examined. This result is shown in FIG.
Shown in

From this figure, it can be seen that the probability P at which the erroneous discharge Y occurs in the panel of the product of the present invention is smaller as the gap δ is smaller, that is, as D / δ is larger, and is zero when D / δ ≧ 3. I understand. In other words, by setting the gap δ to be equal to or less than １ ／ of the distance D between the electrodes, the erroneous discharge Y can be prevented.

Therefore, erroneous discharge Y can be reduced by providing the barrier 35.

(Embodiment 2) Next, as a panel according to Embodiment 2 of the present invention, a 42-inch panel of predetermined rows × 852 columns was used, and the height of the barrier H = 80 (μm), in other words, D / δ = 3 and the range of the inter-electrode distance D where the erroneous discharge Y occurs with respect to the number of rows M was examined. The result is shown in FIG. The other specifications were the same as in the first embodiment.

For comparison, the range of the inter-electrode distance D at which the erroneous discharge Y occurs with respect to the number of rows M was examined in a panel having a conventional structure in which only the barrier 35 of the panel of Example 2 was removed. This result is shown in FIG.

As shown in FIGS. 6 and 15, when the number of rows M of the panel increases, the distance D between the electrodes becomes inversely proportional to the number of rows M (D = 480 × 260 / M = 124800 / M).
From the figure, the erroneous discharge Y at the inter-electrode distance D occurs when the number of rows M exceeds about 600 in the conventional panel, but in the panel according to the second embodiment of the present invention, the inter-electrode distance D has a sufficient margin, It can be seen that this does not occur even when the number M exceeds 800 rows.

Therefore, the provision of the barrier 35 allows the erroneous discharge Y to occur even in the case of the structure of the display electrode pair with high definition.
Can be reduced.

(Embodiment 3) Next, as a panel according to Embodiment 3 of the present invention shown in FIG.
m), electrode width W of scanning electrode 24 and sustain electrode 25 = 4
55 (μm) and the height of the barrier H = 80 (μm), in other words, D / δ = 3, and the distribution of discharge intensity and the luminance distribution between the scan electrode 24 and the sustain electrode 25 were examined. The results are shown in FIGS. 7 (b) and 7 (c).
The other specifications were the same as in the first embodiment.

For comparison, the distribution of the discharge intensity and the luminance distribution were examined with the above-mentioned conventional panel specifications. The results are shown in FIGS. 14 (b) and (c).

As shown in FIGS. 7 (b) and 14 (b), the distribution of the discharge intensity was almost the same between the conventional panel and the panel of the present invention. However, from these figures, the luminance near the bus bars 24b and 25b of the scan electrode 24 and the sustain electrode 25 is reduced to zero in the conventional panel, but is higher than the central luminance of the discharge cell in the panel of the present invention. You can see that it has become. The actual measurement of the panel luminance of the present invention was about 1.3 times the conventional panel luminance. Here, the reason why the luminance is zero in the conventional panel is that the panel is shielded by the buses 24b and 25b,
Further, the reason why the luminance is high in the panel of the present invention is that the panel is not blocked by the buses 24b and 25b,
This is because the phosphor 36 is arranged on the side surface of the barrier 35.

In the first embodiment of the present invention,
The color panel structure using red, blue, and green phosphors is not limited thereto, and a panel structure using only a single color phosphor, a panel structure displaying a gas color without a phosphor, or the like may be used. Further, the driving method of this panel is not limited to the above driving.

Further, the gap 34 according to the first embodiment
Is formed by the front-side substrate 21 and the barrier surface 35a facing the front-side substrate surface 21a, but is not limited thereto, and a round hole, a long hole, a square hole, or the like is provided on the side surface of the barrier 35. May be used. The method of forming the barrier 35 is not limited to the sandblast method, but may be a printing method.

Further, the partition wall 32 according to the first embodiment
Has a height H of the barrier 32 provided only on the front substrate 1 side, but is not limited to this. For example, as shown in FIG. Height bulkhead 3
2a, and a partition wall 32 having a height HT on the front substrate 1 side.
b may be provided.
