Description

Description 'Plasma display panel and its manufacturing, method technical field;

The present invention relates to a plasma display panel and a method for manufacturing the same, and more particularly to a plasma display panel having discharge cells that are partitioned by barrier ribs and color-coded for each column and a method for manufacturing the same. Background art

First, as an example of the basic structure of a plasma display panel (hereinafter also referred to as PDP), an AC 'drive type PDP (AC type PDP) will be described.

A typical AC type PDP has a front substrate and a rear substrate, and a transparent electrode such as I. TO is usually formed on the front substrate, and a bus electrode is formed on the soil. . These transparent electrodes and bus electrodes are covered with a transparent dielectric layer and further covered with a protective film such as MgO. '

On the rear substrate, address electrodes are formed in a direction crossing the transparent electrode and bus electrode on the front substrate. The address electrode is covered with a dielectric, and a partition (rib) is formed thereon.

The barrier ribs have an open structure in which the discharge space in the vertical direction (column direction) is not divided, such as a striped structure, and a box structure (waffle and lattice structure) arranged in a grid so as to surround the four sides of the discharge cell. Can be roughly divided into closed structures such as Between these barriers, red (R), blue (B) and green (G) phosphors are respectively coated. Here, in the box structure, this phosphor is applied. The discharge gap of the electrode on the front substrate is positioned directly above the electric cell. ,

The rear substrate is provided with a second seal portion for sealing the panel around the display area of the panel, and a gap between the inner end portion of the seal portion and the outer end portion of the dummy rib is used to form a partition wall. Noble gases such as Xe and Ne are sealed while discharging the impurity gas inside the panel from the ventilation hole provided outside the display area through the gap between the front panel and the front substrate. Is to be sealed. '

By the way, the PDP with a box barrier rib structure can prevent discharge interference of discharge cells adjacent in the vertical direction in parallel in the horizontal direction (row direction). There is an advantage that the light emitting area can be increased by applying a phosphor on the side surface.

However, the PDP with a box-bulb structure has a narrow gap that can serve as an exhaust path if the four sides of the discharge cell are surrounded by the bulkheads. There is a problem. : '

A barrier rib structure that improves this problem has a barrier rib structure in which the four sides of the discharge cell are surrounded by barrier ribs, and the thermal contraction characteristics of the barrier ribs. Exhaust is improved by using the gap between the top of the partition wall in the horizontal direction and the front substrate as an exhaust path (Patent Document 1 This is because the partition wall is formed of neodymium having a shrinkage shrinkage characteristic. The difference in thickness makes it possible to make a difference in height, and it is not necessary to increase the number of processes In principle, the thicker part of the partition (wider partition) and the thinner part of the partition (narrower partition) This is because the shrinkage in the width direction is small and the shrinkage in the height direction is large. In addition, as a plasma display panel that is excellent in productivity in both rib formation and exhaust treatment, and can realize a bright and stable display, the horizontal rib has a heat shrinkage in the height direction. It is formed with a pattern width of 130% or more of the width of the longitudinal rib so that it is larger than the amount of heat shrinkage in the height direction. In addition, there is also proposed a ventilation passage that is formed in a low shape and passes through the top of the lateral rib (see, for example, Patent Document 2). '

By the way, the amount of impure gas discharged at the time of sealing the panel is different for each color of the phosphor, for example. Therefore, as in the prior art, even if the exhaust route was examined without considering the difference in the amount of impure gas depending on the color of the phosphor, it was difficult to exhaust the impure gas effectively.

First, the principle configuration of the present invention will be described before the embodiments of the plasma display panel according to the present invention are described in detail.

FIG. 1 is a diagram schematically showing the principle configuration of a plasma display panel according to the present invention. In FIG. 1, reference numeral 1 is a front substrate, 2 is a rear substrate, 3 is a vent hole, 4 is a display area, 5 is a seal portion, 1 3 is a gap between the seal portion and the end of the display region, Reference numerals 1 4 1 to 1 4 3 denote exhaust paths in the display cell. Here, for example, reference numeral 1 4 1 represents the exhaust path of the discharge cell coated with the red (R) phosphor, 1 4 2 represents the exhaust path of the discharge cell coated with the green (G) phosphor, and 1 and 4 3 are coated with a blue (B) phosphor. The exhaust path of the discharge cell is shown.

As shown in FIG. 1, the PDP according to the present invention has discharge cells constituting pixels in a vertical direction (column direction) and a horizontal direction (row direction) in a space between the front substrate 1 and the back substrate 2. The display area 4 is formed in a matrix. '.

Around the display area 4, a seal part 5 is provided, and in the seal part 5, a ventilation hole 3 is provided for exhausting the inside of the panel and for discharging discharge gas. . ^ In the display area 4, barrier ribs are formed so as to surround each discharge cell. For example, phosphors of the same color are applied in a repeated pattern in the vertical direction.

In the PDP, the front substrate 1 and the rear substrate 2 are hermetically bonded through a thermal process. The impure gas generated from the phosphors of each color by this thermal process is exhausted from the discharge cell for each color 1 4 1 4 3, and a gap 13 between the seal part 5 and the end of the display area 4 is used to protrude from the vent hole 3. It should be noted that the shape of the non-display area and the position and number of the vent holes 3 are not limited to those shown in FIG. .

P D P according to the present invention improves the exhaust conductance by improving the structure of the partition walls and changing the size of the exhaust path according to the degassing characteristics of the phosphors different in color.

That is, as shown in Fig. 1, the discharge cell exhaust path 14 1 coated with a red phosphor (R phosphor), the green phosphor (G phosphor) is applied. The discharge cell exhaust path 1 4 2 is wide, and the discharge cell exhaust path 1 4 3 is coated with blue phosphor (B phosphor). When sealing the panel For each color phosphor to be discharged According to the amount of impure gas is set according to '.

Specifically, the amount of impure gas discharged from the phosphor when the panel is sealed is, for example, the smallest phosphor for R, the largest phosphor for B, and the phosphor for G both. Accordingly, the discharge path 1 4 1 of the discharge cell coated with the phosphor for R is the narrowest, and the exhaust path 1 4 3 of the discharge cell coated with the phosphor for B is the first. Widely, the exhaust path 14 2 of the discharge cell to which the phosphor for G is applied is wide between them. : '

Hereinafter, embodiments of the plasma display panel and the manufacturing method thereof according to the present invention will be described in detail with reference to the accompanying drawings.

[Embodiment 1] '-FIG. 2 is a perspective view schematically showing a part of a discharge cell in the first embodiment of the plasma display panel according to the present invention, and shows the inside of the back substrate 2 in FIG. It is a fragmentary perspective view.

In the following description of each embodiment, the structure of an AC type three-electrode surface discharge type plasma display panel is used as an example, but the present invention mainly relates to a barrier rib structure for partitioning PDP discharge cells. Therefore, it can be widely applied without depending on the AC type and DC type of the PDP and the discharge method and driving method. '

As shown in Fig. 2, the back substrate 2 has an address electrode 1 2 formed thereon, the dielectric 1 1 covers it, and a vertical partition wall 25 is formed thereon. ing.

Here, between the adjacent vertical walls 25, the phosphor for R 18, the phosphor for B 20, and the phosphor for G 19 are repeatedly applied in order, and these phosphors are applied. It is arranged so that the discharge gap of the electrode of the front substrate (1) comes directly above the discharge cell.

Here, as shown in FIG. 2, in the PDP of the first embodiment, The horizontal barrier ribs 24 (2 4 R, 24 G, and 24 B) separating the vertical discharge cells are formed so as to have different heights depending on the color of the single light body.

FIG. 3 is a transverse cross-sectional view showing the structure of the discharge cell in the first embodiment of the plasma display panel according to the present invention, which is cut along the horizontal direction (^ wall 2 4.

As is apparent from FIG. 3, the height of the partition walls 24 in the horizontal direction is different depending on the color of the applied phosphor. That is, the partition wall 24 R in the region where the phosphor for R 1.8 is not applied is the highest, and the partition wall 24 B in the region where the phosphor for B 20 is applied is the lowest. Further, the height of the partition wall 24 G in the region where the phosphor for G 19 is applied is set to the middle height of the person.

This is because, as described above, for example, when the panel is sealed (thermal process), the impurity gas exhausted from the phosphor is less phosphorous for the R phosphor 18. This is because 20 is the most, and G phosphor 19 is between them. That is, since the amount of impure gas from the phosphor for R 18 is the smallest, the partition wall 2 in the region where the phosphor for R 18 is applied is set to the highest height of the partition wall. (Protective film formed on front substrate 1) Even if the gap (exhaust air path) is narrowed and exhausted sufficiently, the amount of impure gas from phosphor for B 20 is Because it is the most common, the partition wall 24 in the area where the phosphor for B 20 is applied 4 4 B cannot be exhausted enough unless the height of B is made the lowest to widen the gap with the front substrate 1 is there. ,

In the description of this specification, the amount of impure gas discharged from the phosphor when the panel is sealed is the smallest for the phosphor for R 18, the largest for the phosphor for B 20, and The force that the phosphor for G 19 explains as being between the two This is just an example, the most impure gas amount Needless to say, the height of the partition wall 24 in the area where the light is applied is made the lowest, and the exhaust path is widened so that sufficient exhaust is performed.

As described above, according to the PDP of the first embodiment, the size of the gap that becomes the exhaust path after the front substrate 1 and the rear substrate 2 are superposed on each other in the region where the phosphors different in color are applied. The exhaust conductance of the entire PDP can be improved by setting it according to the amount of impurity generated. Further, in a panel having a closed partition wall such as a box structure, it is not necessary to set the partition 24 to be unnecessarily low, so that the effect of suppressing the discharge interference of the partition wall can be maintained. Note that the barrier rib structure in which the height of the barrier ribs is made different according to the color of the applied phosphor as described above, for example, by using a dot printing method (for example, an ink jet method). It is feasible. In addition, when a partition wall is formed by firing a material having heat shrinkage characteristics, the height after firing differs depending on the width even if the partition height before firing is the same height. Thick barrier ribs have less shrinkage in the width direction than thin barrier ribs, but can also be formed using the property that the shrinkage in the height direction is large. By utilizing this characteristic, the height of the horizontal barrier ribs 24 can be formed in accordance with the color of the coated phosphor without increasing the number of processes. An example in which the size of the gap serving as the exhaust path is different in all colors is shown. For example, only the height of the partition wall 24 B in the region where the phosphor 20 B is applied is set to the phosphor 18 for R and When lower than the partition walls 24 R and 24 G in the region where the phosphor for G 19 is applied, the size of the gap serving as the exhaust path may be varied only when one color is used.

[Example 2]

FIG. 4 shows a second embodiment of the plasma display panel according to the present invention. It is a top view which shows typically the discharge cell in.

Shown in Figure 4! As described above, in order to make the height of the horizontal partition walls 24 different according to the color of the applied phosphor, as described above, 'The width of the bulkhead is different.

That is, as described in Patent Document 1 described above, with respect to the partition wall formed of a material having heat shrinkage characteristics, a wide partition wall is smaller in height and contracted in the width direction than a narrow partition wall. The height decreases due to the large shrinkage in the direction. '

Therefore, the partition wall 2 in the region coated with the phosphor for R 2 8 4 has the widest width W 1 of the R, and the partition wall in the region coated with the phosphor for B 2 0 2 4 The width W 3 of B The width W 2 of the partition wall 2 4 G in the region where the phosphor for G 19 is applied is set to be in between.

Further, in the PDP of the second embodiment, the width of the horizontal partition 24 between the discharge cells adjacent in the vertical direction is widened, and a horizontal exhaust path 26 is formed in the partition 2'4. In addition, the exhaust conductance of the discharge cell for each color of RG Β is connected to the vertical exhaust path 1 4 1 to 1 4 3 to further improve the exhaust conductance of the entire PD Ρ. . ''

In this way, by forming the exhaust passage 26 by increasing the width of the horizontal partition 24 between the discharge cells adjacent in the vertical direction, for example, a closed system such as a box structure is formed. In a panel having a partition wall, an effect of suppressing discharge interference can be obtained. As described above, the barrier rib structure can be realized by using the dot printing method.

In the above, in the PDP of the second embodiment, the width of the partition wall 24 is increased in order to form the exhaust path 26 in the lateral partition wall 24, but this increases the width of the partition wall 24 to the outward direction. By increasing the width, it is possible to keep the area of the light emitting region of the discharge cell from changing. The outermost width A discharge cell having a barrier rib that spreads out the phosphor has a minimum height of the barrier rib and requires a wider exhaust path, that is, a discharge cell of a phosphor having the largest amount of impure gas at the firing temperature (for example, A discharge cell coated with phosphor for B 20).

[Example 3]

As shown in FIG. 5, the PDP of the third embodiment is discharged to “. (Burning temperature)” when the panel is sealed in the discharge cell of RBG that is repeatedly arranged in the horizontal direction. This is obtained by removing every other horizontal partition (24 B) of the discharge cell B in the region coated with the phosphor for B 20 having the largest amount of impure gas. A zigzag exhaust path is formed by every other discharge cell B from which the horizontal barrier ribs (24B) are removed and the horizontal exhaust path 26.

As described above, the discharge cell for removing the horizontal barrier ribs is not limited to the discharge cell B in the region where the phosphor 20 for B is applied. The discharge cell G in the area to which the body 18 is applied may also be removed, for example by removing the lateral barriers 2 4 B and 2 4 .G of both the discharge cell B and the discharge cell G You can also ...

Thus, in the PDP of the third embodiment, the discharge cell coated with the phosphor is divided into the cell 2 7 surrounded by the barrier ribs on all sides, and the cell 2 8 sandwiched between the barrier ribs only on both sides in the vertical direction. There will be two types.

With this structure, in addition to the exhaust paths 14 1 to 1 4 3 in the above-described direction, the light-emitting area of the discharge cell in which the horizontal exhaust path 2 6 provided in the non-light-emitting area and the horizontal barrier ribs are not provided. A zigzag exhaust path is also formed through the inside, which makes it possible to exhaust the gas out of the panel evenly and with higher conductance. In addition, it is effective that the phosphor applied to the cell 28 sandwiched between the partition walls only on both sides in the vertical direction has a larger degassing amount at the time of sealing exhaust than other phosphors. The blue (B) phosphor.20 is preferable as described above.

[Embodiment 4] FIG. 6 is a plan view schematically showing a discharge cell in a fourth embodiment of the plasma display panel according to the present invention.

As is clear from the comparison between FIG. 6 and FIG. 5 described above, the P D P of the fourth embodiment is the same as the horizontal partition wall in the P D P of the third embodiment described above.

For every other discharge cell B (28) from which (24 B) has been removed, a partial horizontal partition wall 30 is attached to a part (near) of the path connecting this discharge cell and the lateral exhaust path 6. It has come to provide. This prevents the phosphors in the discharge cells 28 sandwiched between the barrier ribs in the vertical direction from adhering to the gaps that continue in the horizontal direction, and prevents discharge from drying out and deterioration in display image quality (for example, display unevenness). be able to. Further, instead of forming the partial transverse bulkhead 3, the end of the vertical partition 25 may be thickened in the inner direction corresponding to the partial transverse bulkhead 30. '

[Example 5]

As is clear from the comparison between FIG. 7 and FIG. 6 described above, the PDP of the fifth embodiment has a partial transverse barrier rib 3 for every other discharge cell B (28) with the horizontal barrier rib removed. Instead of providing 0, in the horizontal exhaust path 26, a partial vertical partition 3 1 having a height lower than that of the vertical partition 2 5 is provided in the vicinity of the discharge cell 28 sandwiched between the vertical partitions only in the vertical direction. Installed so that the phosphor of discharge cell 28 does not adhere to gaps that continue in the horizontal direction. Thus, it is possible to prevent discharge interference and display image quality degradation.

Here, the width W 5 of the partial vertical partition 3 1 is made wider than, for example, the width W 4 of the vertical partition 2.5, so that the height of the partial vertical partition 3 1 is increased to the partition 2.5. It is designed to be lower than the height.

In the fifth embodiment, a PDP having discharge cells 28 sandwiched between barrier ribs only in the vertical direction shown in FIG. 5 is described as an example. However, for example, all discharges as shown in FIG. It can also be applied to PDPs where the cell has a closed partition wall such as a box structure. '[Example 6]--.

FIG. 8 is a plan view schematically showing a discharge cell in the sixth embodiment of the plasma display panel according to the present invention.

Here, T-shaped protrusions 3 2a of X electrode and T-shape of Y electrode A discharge gap is formed between the protrusions 3 3.

As shown in Fig. 8, the P 'DP of this sixth embodiment is the same as that of the third embodiment shown in Fig. 5 applied to a general AC 3-electrode surface discharge PDP. A metal electrode 34 is formed on a horizontal exhaust path 26 provided between the electrode 3 2 and the Y electrode 3 3. The metal electrode 3 4 improves the contrast by shielding the unnecessary discharge with the metal electrode 3 4 even if an unnecessary discharge occurs due to the phosphor adhering to the exhaust path 26 in the horizontal direction. It ’s like that. Here, the metal electrode 3 4 can be simultaneously formed with the same metal film such as Ag or Cr-Cu-Cr as the bus electrode of the X electrode 3 2 and the Y electrode 3 3. Metal electrode 3 4 itself is used as a predetermined electrode It is also possible to do.

Further, in FIG. 8, an X electrode 32 and a Y electrode 33 having discharge gaps are provided on both sides of the metal electrode 34, but this is an electrode having a discharge cap on one side of the metal electrode 34. It can also be applied to a panel having a structure in which a light shielding layer is provided on the other side.

In FIG. 9, reference numeral 3 5 is a display electrode (Λ electrode: light shielding region), 3 4 a and 3 4 b are T-shaped protrusions of the display electrode made of ITO, and 3 6 is scanning. Display electrodes (bus electrodes) and 35 a- and 35 b show scanning and display electrode T-shaped projections made of ITO or the like.

In the PDP of the seventh embodiment, the metal electrode 3 4 is formed on the horizontal exhaust path 26 in the PDP of the sixth embodiment described above. In the general AC type 3-electrode surface discharge PDP, There is also an AL I S- (Alternate Lighing of Surfaces) system (including e-ALIS (extended-ALIS) system) that shares one bus electrode 3 5, 3 6 with zero-zero cells adjacent in the vertical direction. The PDP is applied.

That is, as shown in FIG. 9, the PDP of the seventh embodiment has the lateral exhaust path 2 6 by disposing the bus electrodes 3 5 and 3 6 on the lateral exhaust path 2 6. Even if unnecessary discharge occurs due to the phosphor adhering to the substrate, the unnecessary discharge can be shielded by the bus electrodes 35 and 36 and the contrast 卜 can be improved.
