2. Description of the Related Art A conventional plasma display panel (hereinafter, referred to as a PDP) will be described with reference to FIGS.
Will be described. FIG. 3 is a perspective view showing the configuration of the plasma display panel. In FIG. 3, a transparent X electrode 32 and an X bus electrode 34 laminated thereon (hereinafter, these electrodes are collectively referred to as an X electrode group), a transparent Y electrode 33 and a transparent Y electrode 33 are formed on the lower surface of a front glass substrate 31. The Y bus electrodes 35 (hereinafter, these electrodes are collectively referred to as a group of Y electrodes) are alternately provided in parallel. The X electrode group and the Y electrode group are covered with a dielectric layer 36, and a protective layer 37 of MgO or the like is further provided thereon.

On the other hand, X on the upper surface of the rear glass substrate 38
An electrode 39 (hereinafter referred to as an address electrode) which vertically crosses the electrode group and the Y electrode group is provided, and the address electrode 39 is covered with a dielectric layer 30. This dielectric layer 3
A partition wall 51 is provided on 0 in parallel with the address electrode 39, and the address electrode 39 is provided between the two partition walls 51. Further, RGB phosphors 52 are applied in stripes on the wall surfaces of the partition walls 51 and the upper surface of the dielectric layer 30, respectively. The front glass substrate 31 and the rear glass substrate 38 are sealed with a sealing material such as frit glass at the sealing portion at the end, and N is filled in a gap between the front glass substrate 31 and the rear glass substrate 38.
Gases such as e and Xe are sealed.

FIG. 4 is a plan view of a plasma display panel. In the drawing, 41 is a display area for displaying an image, and 42 is a non-display area where no image is displayed. 43
Indicates a range of formation of a sealing material such as frit glass provided for sealing the front glass substrate 31 and the rear glass substrate 38. The display area 41 includes a front glass substrate 31.
And a plurality of discharge cells divided by a partition wall 51 at an intersection of an X electrode group and a Y electrode group attached to the pixel electrode and an address electrode 39 attached to the back glass substrate 38 so as to three-dimensionally intersect the X electrode group and the Y electrode group. A desired image is obtained by independently driving.

FIG. 5 is a partial cross-sectional side view of the end of the plasma display panel when FIG. 3 is viewed from the direction of arrow D1. In the figure, the same components as those in FIGS. 3 and 4 are denoted by the same reference numerals, and the description will be omitted. The dielectric layer 36 and the protective layer 37 formed on the front glass substrate 31 and the dielectric layer 30 formed on the rear glass substrate 38 are usually coated with a dielectric paste or a protective layer paste using a squeegee. The thickness of these pastes varies at the edge of the glass substrate corresponding to the peripheral edge of the region where each film is formed. As a result, the thickness of the dielectric layers 30 and 36 and the protective layer 37 at the edges of the glass substrates 31 and 38. There is a problem that pod width varies greatly and is not stable. Usually, in order to stabilize the film thickness in the display area 41, the dielectric layer 36, the protective layer 37, and the dielectric layer 30 are wider than the display area 41, that is, beyond the display area 41,
It is formed in a range that covers even up to.

For the same reason, the areas where the address electrodes 39, the partition walls 51, and the phosphors 52 are formed are also provided over a wider area than the display area 41 actually used, that is, over the non-display area 42. 41, a stable film thickness is obtained. Each film formed in the non-display area 42 is subjected to the same processing as in the display area 41. Now, non-display area 4
In order to distinguish the address electrode 39, the partition wall 51, and the fluorescent body 52 provided in the display area 41 from the address electrode 39, the partition wall 51, and the fluorescent body 52 provided in the display area 41, respectively, the dummy address electrode 39D, the dummy partition wall 51D, and the dummy fluorescent body are provided. 52D. The partition wall 51 is formed by thick film printing, sandblasting, or the like, and the top surface thereof is combined with the surface of the protective layer 37 of the front glass substrate 31 so as to be in contact with each other. .

The X bus electrode 34 and the Y bus electrode 35 are each extended to the end of the front glass substrate 31 to be connected to a driving circuit. The address electrodes 39 and the dummy address electrodes 39D are connected to the rear glass substrate. It extends to the end of 38. For this reason, a space separated by the dummy partition wall 51D is formed at the intersection of the X electrode group and the Y electrode group and the dummy address electrode 39D also in the non-display area 42 not related to display, and the dummy discharge cell 11D is formed here.
Is configured.

In such a PDP, the display area 41
In the plurality of discharge cells 11, in order to obtain a desired display image, a preliminary discharge period (or a reset period) in which the state of charge of all discharge cells is the same between the X electrode group, the Y electrode group, and the address electrode 39. ), A write discharge period (or address period) in which an address pulse is applied to the address electrode 39 and a pulse is simultaneously applied to the Y electrode group to select and discharge a predetermined discharge cell 11 to accumulate electric charges, And a Y-electrode group, a pulse is alternately applied, and a display sustain discharge period (or a sustain period) in which a selected cell is discharged by a write discharge for a certain period is periodically repeated.

In the dummy discharge cell 11D formed at the end of the non-display area 42, no address pulse is applied to the dummy address electrode 39D, and thus no lighting control is performed. However, the X electrode 32, the Y electrode 3
3 is common to the discharge region 41 and the non-discharge region 42,
The pulses of the preliminary discharge and the display sustaining discharge applied to the X electrode 32 and the Y electrode 33 are also applied to the dummy discharge cell 11D.
It is desirable that the charge generated in one discharge cell be controlled in the discharge cell, but the charge may move to the adjacent cell beyond the partition wall 51. Therefore, the display area 41
Dummy cell 1 adjacent to discharge cell 11 formed in
Unnecessary charges may be accumulated in the pre-discharge, the write discharge, and the display sustain discharge in the 1D, or may be affected by noise, thereby causing erroneous light emission (erroneous discharge). That is, although the normal non-display area 41 does not discharge, the dummy discharge cells 11D in the non-discharge area 42 are configured in the same manner as the discharge cells 11 in the display area 41. Discharge may occur during the sustain discharge period to degrade image quality.

[0010]

In the non-display area 42, a dummy discharge cell 11D having the same shape as that of the display area 41 is formed. However, it is desirable not to discharge in view of display quality. However, the partition 5 interposed between the display area 41 and the non-display area 42
There is a problem that the charge moves beyond 1 or the charge is accumulated in the dummy cell 11D in the non-display area 42 during each discharge period, causing unnecessary discharge and erroneous light emission. Furthermore,
Since the lighting status changes according to the setting status of the drive waveform,
There is a problem that the degree of freedom in setting the drive waveform is reduced. For example, the X electrode 32 in a preliminary discharge period or a display sustain discharge period,
When the driving waveform applied to the Y electrode 33 is changed, the display area 4
1, the image quality is improved, but erroneous discharge occurs in the non-display area 42, which causes a problem that the degree of freedom of the drive waveform is reduced. Therefore, countermeasures such as leaving the dummy address electrode 39D attached to the non-display area 42 in a floating state, directly connecting to the GND, or connecting to the GND via a resistor are conceivable. The effect of completely preventing the erroneous light emission was not obtained.

An object of the present invention is to provide a discharge type display panel and a display device in which unnecessary discharge in dummy discharge cells formed in a non-display area is eliminated and display quality at the end of the display area is improved.

[0012]

In order to achieve the above object, according to the present invention, a dummy partition conventionally formed in a non-display area is not formed in the same shape as a partition in a display area, but is buried between the dummy partitions. Or a shape in which the discharge space becomes narrow. Thus, even if a voltage similar to that of the discharge cells is applied to the dummy discharge cells, it is possible to reduce the charge transfer from the adjacent cells and the accumulation of charges generated during each discharge period. Furthermore, by narrowing the discharge space by the shape of the dummy partition wall, the voltage of the dummy discharge cell can reach a higher voltage than the discharge voltage of the display area, and the discharge can be performed even when the same voltage is applied to the display area. It becomes difficult.

In order to achieve the object of the present invention, the first invention has a display region in which discharge cells are formed by a plurality of partition walls and a non-display region in which dummy discharge cells are formed by a plurality of dummy partition walls.

In the first aspect of the present invention, a part of the plurality of dummy partitions may be buried between dummy partitions to reduce the volume of a discharge space of the dummy discharge cells. Further, the volume of the discharge space of the dummy discharge cell may be reduced by embedding the space between all of the plurality of dummy partitions.
Further, a dummy wall having a height lower than that of the dummy partition may be formed in a part of a portion where the plurality of dummy partitions are formed to reduce a volume of a discharge space of the dummy discharge cell.

In the first aspect of the present invention, the volume of the discharge space of the dummy discharge cell may be reduced by forming a dummy wall having a height lower than that of the dummy partition at a portion where the plurality of dummy partition is formed. Good. In addition, the space between some of the plurality of dummy barrier ribs may be made smaller than the space between the barrier ribs in the display area to reduce the volume of the discharge space of the dummy discharge cells. Still further, the space between the dummy partitions may be partially buried below the height of the dummy partitions to reduce the volume of the discharge space of the dummy discharge cells.

The discharge cell is configured to have a volume smaller than that of the discharge cell.

In the second invention, the volume of the discharge space of the discharge cell formed in the non-display area may be smaller than the volume of the discharge space of the discharge cell formed in the display area. Further, by changing the shape of the partition, the volume of the discharge space of the discharge cells formed in the non-display area may be made smaller than the volume of the discharge space of the discharge cells formed in the display area. Good.

In the second aspect, a dummy wall may be provided in the partition portion formed in the non-display area.
Further, an interval between the partition walls formed in the non-display area may be smaller than an interval between the partition walls provided in the display area. The discharge space formed in the non-display area adjacent to the display area may be filled in a discharge space formed between the partition and a substrate disposed opposite to the partition.
Further, at least one line of a discharge space formed in the non-display area adjacent to the display area may be buried in a discharge space formed between the partition and a substrate arranged opposite to the partition.

Further, a discharge space formed in the non-display area adjacent to the display area is buried so as to be lower than the height of the partition wall formed in the display area, and formed in the non-display area. The discharge space may be narrowed. Further, the interval between the partition walls formed in the non-display area may be smaller than the interval between the partition walls formed in the display area.

According to a third aspect of the present invention, the display device has a display region in which discharge cells are formed by a plurality of partition walls and a non-display region in which dummy discharge cells are formed by a plurality of dummy partition walls. In a display device which displays an image by controlling the driving voltage, a volume of a discharge space of the dummy discharge cell is made smaller than a volume of a discharge space of the discharge cell in the display area.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the discharge type display panel of the present invention will be described with reference to the drawings, using some examples. FIG. 1 is a partial sectional side view showing one embodiment of a discharge type display panel according to the present invention, and FIG.
2 shows a cross section of a main part of a panel end viewed from the direction of FIG. In the drawing, the left side separated by a broken line shows a cross section of the non-display area 42, and the right side shows a cross section of the display area 41. In the display area 41 and the non-display area 42, the X electrode 32, the X bus electrode 34, the Y electrode 33, the Y bus electrode 3
5, the dielectric layer 36 and the protective layer 37 are similarly provided.
An address electrode 39 and a dielectric layer 30 are similarly attached to the rear glass substrate 38. In the display area 41, a space for filling gas is formed by the front glass substrate 31, the rear glass substrate 38, and the partition wall 51, and the space of the X electrode group, the Y electrode group, and the address electrode 39 in the space partitioned by the partition wall 51, respectively. In the space located at the intersection, discharge cells 11 are formed, and a plurality of discharge cells 11 are formed in the display area 41. By controlling the plurality of discharge cells 11 to emit light, a display image can be obtained.

Now, the two partition walls 51 and the front glass substrate 31
And a rear glass substrate 38 to form a display area 41.
The space extending in the direction of arrow D1 in FIG. 3 is called a discharge space. Similarly, the non-display area 42 includes the two dummy partitions 51D, the front glass substrate 31, and the rear glass substrate 38.
Is referred to as a dummy discharge space.

In FIG. 1, the dummy wall 55D is formed by filling the dummy discharge space, that is, the space between the dummy partitions 51D in the non-display area 42 with the same material as the dummy partition 51D so that the dummy discharge cells 11D are not formed. Since the dummy discharge space is buried in this manner to reduce the space in which the electric charge is stored, the dummy discharge cell 11D is not formed. Accordingly, it is possible to reduce the accumulation of the electric charge that moves to the dummy discharge cell 11D beyond the partition wall 51 and the electric charge generated by the preliminary discharge, the write discharge, and the display sustain discharge.

Further, by providing the dummy wall 55D, the voltage that causes the discharge in the non-display area 42 can be higher than the voltage that causes the discharge in the display area 41. That is, even if the same voltage is applied to the non-display area 42 as that of the display area 41, the probability of a discharge is reduced. In addition, since the dummy discharge cells 11D are not formed in the non-display area 42, the accumulation of electric charges can be reduced. Further, even if a small amount of electric charge is accumulated, the voltage to discharge becomes higher than that of the display area 41. 42
Unnecessary discharge at the time can be significantly reduced or eliminated. By providing the dummy wall 55D, the space between the partition walls at the left and right ends tends to be widened due to the shrinkage. However, the space can be made uniform by performing mask correction in advance.

FIGS. 2 (a) to 2 (d) are partial cross-sectional side views showing another embodiment of the discharge type display panel according to the present invention, and show the main part of the panel end. The same components as those in FIG. 1 are denoted by the same reference numerals, and description thereof will be omitted.
In FIG. 2A, a dummy wall 56D in which the height of the dummy wall 55D described with reference to FIG. 1 is set low is provided. Assuming that the height of the dummy partition wall 55D in FIG. 1 is h, in FIG. 2A, the height of the dummy wall 56D is formed to be h / 2.

Although the dummy wall 56D having a height of h / 2 is formed so as not to fill the entire dummy discharge space but to leave a small space, it has an effect of reducing charge accumulation. The voltage at which discharge occurs in the non-display area 42 is the display area 4
1 can be set higher than the voltage that leads to discharge. For this reason, even if the same voltage as that in the display area 41 is applied, the probability of a discharge in the non-display area 42 is reduced.

In FIG. 2A, the height of the dummy wall 56D is set to h / 2 of the height h of the dummy wall 55D. However, even if the same voltage as that of the display area 41 is applied, the partition wall does not lead to discharge. Since the height may be set to, for example, h / 3 may be set. Since the height of the dummy wall 56 varies depending on the manufacturing method and structure of the PDP, it can be set by an experiment by cut and try.

FIG. 2B shows a plurality of dummy discharge spaces 1 adjacent to the display region 41 without filling all of the dummy discharge spaces among the dummy discharge spaces formed in the non-display region 42.
1D is embedded. Erroneous light emission in the non-display area 42 of the PDP is caused by the display area 4 in the non-display area 42.
This occurs in several dummy discharge cells 11D adjacent to one. In particular, the dummy discharge cells 11D for one pixel adjacent to the display area 41, that is, three dummy discharge cells 11D,
It is easily affected by the display area 41, and there is a high probability that charges move from adjacent cells. For this reason, the dummy discharge space to be embedded is effective even for a few lines adjacent to the display area 41. In FIG. 2B, of the six lines of dummy discharge cells 11D, one line of dummy discharge cells 11D adjacent to the display area 41 is buried to form a dummy partition wall 57D. With such a configuration, the display area 41
Dummy discharge cells 11 that are susceptible to
Since the space of D is eliminated, the movement of the charge can be reduced or prevented, and the movement of the charge to the dummy discharge space which is not buried can be further reduced or prevented. The dummy discharge space to be embedded may be a space of two lines adjacent to the display area 41 or may be three lines. That is, assuming that there are six lines of dummy discharge spaces, how many lines of dummy discharge spaces are filled to prevent erroneous discharge in the non-display area 42 depends on the structure and manufacturing method of the PDP. It can be confirmed by an experiment how many lines are filled up. Also,
Increasing the number of dummy spaces to be buried increases the effect of preventing erroneous discharges.
Can be configured. In FIG. 1, when there are six lines of dummy discharge spaces, all six lines are embedded and the dummy wall 55D is formed.
Is composed.

In FIG. 2C, the dummy partitions 5 formed in the non-display area 42 are compared with the intervals between the partitions 51 in the display area 41.
The 1D interval is narrowed. Usually, assuming that the distance between the two partition walls 51 is d, in this embodiment, the dummy partition walls 51D are arranged so that the distance between them is d / 2. In this way, by making the space between the dummy partitions 51D in the non-display area 42 smaller than the space between the partitions 51, the dummy discharge cells 12D having a narrow space can be formed. The voltage that reaches the discharge in the dummy discharge cell 12D is higher than that of the discharge cell 11 in the display area 41 because the discharge space is narrow.

During the display sustain discharge period, a voltage is applied to the X electrode group and the Y electrode group, and the discharge cell 11 selected during the write discharge period causes a discharge to emit light. Dummy discharge cell 1
In 2D, erroneous light emission may occur due to movement of electric charges from the display area 41 or influence of noise. However, since the formation interval of the dummy partition walls 51D is narrow and the discharge space of the dummy discharge cells 12D is narrow, discharge occurs. Voltage is high. For this reason, discharge is less likely to occur and erroneous light emission can be reduced. The dummy address electrodes 39D are arranged so as to be located in the middle of the two partition walls, but are provided for stabilizing the dimensions of the address electrodes 39 in the display area 41 and are not subjected to discharge control. In this embodiment, the dummy address electrodes 39D are not necessarily located at the center, but the dummy address electrodes 39D are formed at the same interval as the display area 41 in FIG.
Also, the dummy partition walls 51D may have an arbitrary number, and the arrangement interval thereof is such that the voltage that causes the discharge in the non-display area 42 is higher than the voltage that causes the discharge in the display area 41, as in d / 3 and d / 4. It should just be set to become.

In FIG. 2D, a floor 58D is provided at the bottom between the dummy partition walls 51D to reduce the height of the dummy discharge space 11D. Usually, the dummy discharge space 11
The height of D is substantially the same as the height of the dummy partition wall 51D.
In the figure, when the height of the discharge space in the display area 41 (the height of the discharge cells 11 is substantially h), the height of the dummy discharge space in the non-display area 42 is h / 2, so that the dummy partition wall 51D is formed.
And a floor 58D covering the top of the dielectric layer 30
Is formed. It has been found that increasing the thickness of the dielectric layers 36 and 30 increases the voltage at which discharge occurs. With such a configuration, the same effect as in the case where the dielectric layer 30 is made thicker can be obtained. Therefore, even if the charge is moved to the dummy discharge cell 11D adjacent to the display region 41, the charge accumulation can be reduced. Yes, and the display area 41
Even if the same voltage is applied, the discharge hardly occurs in the non-display area 42.

In FIG. 2D, the height of the dummy discharge space is h.
The floor 58D is formed so as to be / 2, but the height may be higher than a predetermined value, and the predetermined value can be obtained by experiment according to the structure and manufacturing method of the PDP.
The point is that it is only necessary to set the voltage that causes the discharge in the non-display area 42 to be higher than the voltage that causes the discharge in the display area 41.

In all the embodiments, the non-display area 42 is provided with a dummy address electrode 39D, a dummy phosphor 52D, and the like, on which the dummy wall 5 is made of the same material as the partition wall 51.
5D, 56D, a dummy partition 57D, and a floor 58D are provided. The dummy address electrodes 39D and the dummy phosphors 52D are provided on the address electrodes 3 attached to the display area 41.
9. It is provided to stabilize the dimensions of the phosphor 52. Although the dummy address electrode 39D is necessary for stabilizing the dimensions, it is not necessary for the dummy address electrode 39D to be arranged between the dummy partition walls 51D because it is not related to the actual display.

The dummy partition wall 51D, the dummy wall 55
D, 56D, dummy partition 57D, and floor 58D are formed as follows:
Since it is sufficient to prepare a mask pattern corresponding to the shape, it can be realized relatively easily without adding a new manufacturing process.

As described above, in the present invention, by setting the volume of the discharge space of the dummy discharge cells in the non-display area smaller than the volume of the discharge space of the discharge cells in the display area, erroneous discharge in the non-display area can be achieved. Can be prevented. Therefore, the objects and effects can be achieved by configurations other than those described in this embodiment. For example, the volume of the discharge space in the non-display area may be reduced by changing the shape of the dummy partition wall. In addition, a sufficient effect can be obtained only by reducing the interval between some of the dummy partitions without reducing the entire interval between the dummy partitions. Further, the height of the dummy partition wall itself may be reduced.

According to the present invention, the dummy discharge cells 11D in the non-display area 42 adjacent to the discharge cells 11 in the display area 41
Thus, it is possible to prevent the accumulation of electric charges in the PDP, to set the voltage at which the dummy discharge cell 11D is discharged to a high level, to eliminate unnecessary light emission at the end of the PDP, and to improve the quality of the image at the display end.

[0038]

According to the present invention, unnecessary light emission at the display end of the display device can be eliminated, and the quality of the image at the display end can be improved.
