DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a three-electrode surface-discharge type plasma display panel (PDP) for displaying a matrix of various colors using phosphors.

2. Description of the Related Art PDPs are capable of displaying images at a higher speed than liquid crystal panels and are easy to increase in size. Therefore, use of PDPs in fields such as OA equipment and public information display devices has begun to spread. Further, for example, progress is expected in the field of high definition television.

[0003] With the expansion of such uses, PD
In P, it is particularly desired to improve the visibility of color display.

[0004]

2. Description of the Related Art A matrix display type PDP selectively emits light in unit light-emitting regions arranged in rows and columns.
Display arbitrary characters and figures.

[0005] Among these types of PDPs, a surface discharge type PDP having a three-electrode structure suitable for color display using a phosphor is provided on one substrate with a pair of display electrodes (main electrodes for surface discharge) adjacent to each other in parallel with each other. ) And a plurality of address electrodes orthogonal to each electrode pair.

In each unit light emitting region, a selected discharge cell for selecting display or non-display is defined at an intersection of one display electrode and an address electrode, and display is performed by an electrode pair in the vicinity of the selected discharge cell. Main discharge cells (surface discharge cells) are defined.

FIG. 6 is an exploded perspective view showing a sectional structure of a portion corresponding to one unit light emitting region EU of a conventional surface discharge type PDP 1j. In the figure, the unit light emitting region EU on the inner surface of the glass substrate 11 (the surface on which the display electrodes X and Y are formed)
Is indicated by a two-dot chain line.

In the PDP 1j, a pair of display electrodes X and Y corresponding to one line of display are formed on the inner surface of the glass substrate 11 on the display surface H side of the glass substrates 11 and 21 opposed to each other with the discharge space 30 interposed therebetween. Are located.

The display electrodes X and Y are covered with a dielectric layer 17 for AC driving. On this dielectric layer 17, for example, a grid-like partition wall 19W for dividing the discharge space 30 into unit light emitting regions EU. Is provided. When performing multi-color or color display, one pixel (dot) for display is constituted by the plurality of unit light emitting areas EU.

The display electrodes X and Y are formed of a wide band-shaped transparent conductive film (a Nesa film or the like) 41 and a narrow band-shaped metal film (Cr-Cu-
42). That is, light shielding by the display electrodes X and Y is minimized. Also,
The surface of the dielectric layer 17 is covered with a protective film made of MgO (not shown) together with the partition wall 19W.

On the other hand, on the inner surface of the glass substrate 21 on the rear side, a strip-shaped partition wall 29 defining a discharge space 30 and defining the gap size thereof together with the partition wall 19W, and a unit light emitting region E
An address electrode A for selectively causing U to emit light and a phosphor 28 of a predetermined emission color are provided.

The address electrode A is arranged so as to approach one end of the unit light emitting region EU, that is, adjacent to one of the partition walls 29 on both sides of the unit light emitting region EU.
8 is arranged on the surface of the glass substrate 21 between the address electrode A and the other partition 29.

At the time of display, for example, display electrodes X and Y
, A driving voltage exceeding the discharge starting voltage (depending on the composition of the discharge gas) is applied. As a result, surface discharge in the surface direction of the dielectric layer 17 occurs, and the surface discharge stops when a predetermined amount of wall charge is accumulated in the dielectric layer 17. Thereafter, a discharge sustaining voltage (display pulse) having a polarity opposite to the wall charge is applied to the display electrodes X,
Each time Y is alternately applied, a surface discharge occurs, and the ultraviolet light generated at this time excites the phosphor 28 to emit light.

When the unit light emitting region EU is not to emit light, the address voltage (erase pulse) is applied to the address electrode A at a predetermined time in synchronization with the discharge sustaining voltage.
Is applied. As a result, the wall charges disappear, and no surface discharge occurs thereafter.

[0015]

Generally, a surface discharge type PD
In P, the gap size of the discharge space 30 (that is, the PDP) is used to alleviate the ion bombardment of the phosphor 28 during the discharge.
1j) is 100 to 100.
It is selected to be about 130 μm.

For this reason, in the conventional PDP 1j having the phosphor 28 only on the surface of the glass substrate 21 as described above, when the display is viewed from an oblique direction with respect to the display surface H, the partition walls 19W and 29 are used. Visibility is impaired. That is, conventionally, there was a problem that the viewing angle of display was small. The higher the definition, the smaller the viewing angle.

Further, since the surface area itself (substantial light emitting area) of the phosphor 28 in the unit light emitting region EU is small, there is also a problem that the display brightness when viewed from directly in front of the display surface H is low. Was.

An object of the present invention is to provide a PDP which has a large viewing angle and is capable of high-luminance display in view of the above problems.

1 and 2 are exploded perspective views showing the cross-sectional structures of the main parts of surface discharge type PDPs 1 and 2 according to first and second embodiments of the present invention, respectively. In these figures, FIG.
Components having the same functions as those described above are denoted by the same reference numerals regardless of the difference in shape, and description thereof will be omitted or simplified.

In FIG. 1, a PDP 1 is a surface discharge type PDP having a three-electrode structure in which a pair of display electrodes X and Y and an address electrode A are associated with a unit light emitting area EU. The display electrodes X and Y each include a strip-shaped transparent conductive film 41 and a strip-shaped metal film 42, and are arranged on the inner surface of the glass substrate 11 on the display surface H side.

On the dielectric layer 17 covering the display electrodes X and Y, there is provided a strip-shaped partition wall 19 made of low-melting glass extending in a direction perpendicular to the display electrodes X and Y. It is partitioned for each unit light emitting area EU in the extending direction of the display electrodes X and Y.

In the PDP 1, in order to prevent discharge interference (coupling of discharges) between display lines, the sum of the widths of the display electrodes X and Y and the discharge gap (the width of the electrode pair) is determined by the line pitch (the width of the electrode pair). This value corresponds to the length of the unit light emitting region EU in the direction orthogonal to the display electrodes X and Y, and its value is, for example, about 220 μm) and is selected to be 0.7 times or less.

On the other hand, a strip-shaped partition 29 having substantially the same height as the above-described partition 19 and extending in the same direction is provided on the glass substrate 21 on the rear side. The size of the gap in the discharge space 30 is defined by the partition wall 19.

An address electrode A having a predetermined width is arranged between the partition walls 29 by, for example, pattern printing and baking of a silver paste. The phosphor 28 is provided so as to cover the inner surface of the glass substrate 21 except for the portion of the partition wall 29 which is in contact with the display surface H side and the vicinity thereof. That is, in the PDP 1, the phosphor 28 is provided on almost the entire wall surface of the discharge space 30 on the glass substrate 21 side in the unit light emitting region EU, including the side surface of the partition wall 29 and the surface of the address electrode A. .

In the PDP 1 having the above structure, the partition 2
Since the side surface 9 also becomes a light emitting surface, the viewing angle of display is large. Further, as compared with the conventional PDP 1j, the light emitting area is increased by an amount corresponding to the partition 29 and the address electrode A, so that the display brightness is increased.

In FIG. 2, PDP 2 is a display electrode X
2, three unit light emitting regions EU arranged in the extension direction of Y2
It is configured to perform color display in association with pixels. On the inner surface of the glass substrate 11 on the display surface H side, display electrodes X2 and Y2, a dielectric layer 17, and a protective film 18 made of MgO are sequentially laminated.

The display electrodes X2 and Y2 are connected to the unit light emitting region EU.
It is composed of a strip-shaped transparent conductive film 412 having a notch k for localizing a surface discharge every time, and a strip-shaped metal film 42 having a constant width. That is, the planar shapes of the display electrodes X2 and Y2 are selected such that the display electrodes X2 and Y2 are adjacent to each other with a predetermined discharge gap therebetween at the center of the unit light emitting region EU, and the gap therebetween is large at both ends of the unit light emitting region EU. Have been. The ratio of the width of the electrode pair to the line pitch is P
As in DP1, it is selected to be 0.7 or less.

On the other hand, an underlayer 5 for uniformly covering the surface of the glass substrate 21 is provided on the inner surface of the glass substrate 21 on the rear side.
1, an address electrode A2, a partition 292, and a phosphor 28 are sequentially stacked.

The underlayer 51 is made of a low-melting glass (however, the melting point is higher than that of the low-melting glass for the partition), and the address electrode A and the partition 292 are formed on the glass substrate 21 made of a soda-lime glass plate by a thick film method. When formed by
Absorbs the solvent in the paste and suppresses shape loss. The base layer 51 is colored white, for example, by adding an oxide or the like, and also plays a role as a light reflection film.

The address electrode A2 is a silver electrode whose surface color is obtained by setting firing conditions appropriately. The partition wall 292 has a height substantially corresponding to the gap size of the discharge space 30, and is made of a low-melting glass layer having a different color depending on its location. That is, in the partition wall 292,
The top 292B is dark (e.g., black) to improve display contrast, and the other portion 292A, which occupies most of the height, is light (e.g., white) to increase luminance. . Such a partition wall 292 is formed by printing a low-melting glass paste to which aluminum oxide, magnesium oxide, or the like is added as a white colorant several times, and then printing a low-melting glass paste to which a black pigment is added. It can be formed by firing color low-melting glass pastes at once.

The phosphor 28 is provided so as to cover the inner surface of the glass substrate 21 except for a portion in contact with the display surface H side (the protective film 18) of the partition wall 292 and its vicinity. I have. That is, the phosphor 28 is provided on almost the entire wall surface of the discharge space 30 on the glass substrate 21 side in the unit light emitting region EU, including the side surface of the partition wall 292 and the surface of the address electrode A2.

The emission colors of the respective phosphors 28 corresponding to the three unit emission regions EU constituting one pixel are set to red (R), green (G), and blue (B) in this order (in the figure). The letters R, G, and B indicate emission colors.)

In the PDP 2 configured as described above, the discharge space 30 is defined by the partition 292 provided on the glass substrate 21 side, and the phosphor 2 is disposed on the side surface of the partition 292.
8, compared with the PDP 1 of the above-described embodiment, only the partition is not provided on the glass substrate 11 side (the partition 2
Only the difference between the height of the partition 92 and the height of the partition wall 29) is such that the surface on which the phosphor 28 is formed extends toward the display surface H, and the viewing angle is large and the luminance is high.

In addition, since the respective portions located on the back side of the phosphor 28, that is, the underlayer 51, the address electrode A2, and the partition wall 292 are colored white or a bright color close thereto, the light traveling toward the back is obtained. Is reflected to the display surface H side. For this reason, the PDP 2 is advantageous in that the utilization efficiency of light emission is high and the luminance is increased.

According to the above-described embodiment, since the phosphors 28 are provided on the side surfaces of the partition walls 29 and 292 together with the surface of the glass substrate 21, it is possible to improve the display brightness and improve the viewing angle.

That is, as shown in FIG.
Is provided also on the side surfaces of the partition walls 29 and 292 (shown by a solid line in the figure), compared with the case where the phosphor 28 is provided only on the surface of the glass substrate 21 (shown by a broken line in the figure). , The luminance in front of the display surface H (viewing angle 0 °) is about 1.35.
Doubled. In addition, a wide range (viewing angle is −60 ° to +6
(A range of 0 °), a luminance equal to or higher than that of the frontal plane can be obtained.

Focusing particularly on the viewing angle dependence of the luminance, as shown in FIG.
The reflective PDPs 1 and 2 also provided on the side surfaces of the second panel 2 are superior to the transmissive PDPs in which the phosphors 28 are disposed on the glass substrate 11 on the display surface H side.

According to the above-described embodiment, the ratio of the width of the electrode pair for the surface discharge to the line pitch (herein referred to as the occupancy rate) is selected to a value of 0.7 or less. Can be prevented, and an operation margin (permissible range of the driving voltage) required for reliably performing a normal display can be secured.

That is, as shown in FIG. 5, when the occupancy ratio is larger than about 0.7, the discharge starting voltage Vf is reduced and erroneous discharge is likely to occur between adjacent lines. If it is 0.7 or less, the discharge starting voltage Vf is substantially constant, and erroneous discharge hardly occurs. Also, the minimum discharge sustaining voltage Vsm is almost constant if the occupancy rate is 0.7 or less. However, when the occupancy ratio is larger than 0.7, the minimum discharge sustaining voltage Vsm increases due to interference of discharge between lines. Therefore, the occupancy rate is set to 0.
By selecting a value within the range of 7 or less, reliable driving is facilitated.

Actually, the display electrodes X, X2, Y,
If the width of Y2 is smaller than about 20 μm, disconnection is likely to occur. Therefore, the lower limit of the occupancy rate is usually about 0.15.

According to the embodiment of FIG. 2 described above, the gap size of the discharge space 30 is defined only by the partition wall 292 on the glass substrate 21 on which the address electrode A is disposed, so that predetermined components are provided. The tolerance when the glass substrates 11 and 21 are arranged to face each other is large, and the manufacturing is easy. For example, in a structure in which partition walls are provided on both substrates, when the pitch of the unit light emitting region EU is 220 μm, high-accuracy alignment with a tolerance of about ± 8 μm is required. On the other hand, in the structure of the PDP 2, the allowable error is on the order of millimeters, so that the alignment is greatly facilitated and an inexpensive glass substrate having a large shrinkage ratio in the firing step can be used.

In the above-described embodiment, the phosphor 28 may be mixed with indium oxide or the like to impart conductivity, thereby suppressing the charging of the phosphor 28 during the selective discharge and facilitating the driving. In the above-described embodiment, the reflection type surface discharge type PDP 1, in which the phosphor 28 can directly see the light emitting surface from the display surface H, is used.
2, the present invention can be applied to a transmissive surface discharge type PDP that uses light transmitted through the phosphor 28 as display light. In that case, opaque electrodes may be provided as the display electrodes X and Y.

In the embodiment of FIG.
2, and a coloring material mixed for coloring the underlayer 51 can be appropriately selected.

[0052]

According to the first to thirteenth aspects of the present invention, a display screen having a large viewing angle and high luminance can be realized.

According to the first aspect of the present invention, the luminance can be further increased by the light reflection of the partition walls. According to the second aspect of the present invention, the brightness can be further increased and the contrast can be improved. According to the third aspect of the present invention,
The trust can be good.

According to the fourth aspect of the present invention, the luminance can be further increased by the light reflection of the address electrode. According to the fifth aspect of the invention, the luminance can be further increased by light reflection of the underlayer for facilitating the formation of the address electrode.

According to the sixth aspect of the present invention, light emitted from the surface layer of the phosphor can be efficiently emitted from the display surface, thereby increasing display brightness. According to the seventh aspect of the present invention, it is possible to suppress the spread of the unnecessary discharge in the extension direction of the display electrode, and to facilitate the driving.

According to the invention of claim 8, it is possible to suppress the interference of discharge between the unit light emitting regions arranged in the arrangement direction of the display electrodes, so that a partition for dividing the discharge space for each unit light emitting region EU becomes unnecessary. Thus, the structure can be simplified.
