Description

Detailed Description of the Invention [Industrial Application Field] The present invention provides a vertical electrode plasma display panel in which a partition wall for forming display discharge cells between x and Y electrodes can be easily formed. (hereinafter simply referred to as FDP).

[Conventional technology] Conventional FDPs are formed in a counter-electrode discharge type in which the discharge surface of the discharge electrode is parallel to the substrate (for example, the back plate), so the discharge space is small, the luminance is low, and the luminous efficiency is poor. There was a problem. In order to solve these five problems,
In Japanese Patent Application No. 62-217403, the present applicant proposed a vertical electrode FDP in which the discharge surface of the discharge electrode has a substantially angle of view with the substrate.

[Problems to be Solved by the Invention] The above-mentioned vertical electrode FDP is, as shown in FIGS. 5 and 6, a plurality of rows of vertical electrodes that generate a display discharge between adjacent parallel discharge surfaces. ..., Xn, Xn4. , . . . , Y+a, Ym+, . . . are provided alternately, and multiple columns of write electrodes WIL1. It is constructed by providing WQ, WQ+I... (1) is a partition wall made of an insulator for partitioning the discharge cells S, (2) is a dielectric layer, (3) and (4) are glass front and back plates, (5)
) is a phosphor layer 6 However, the vertical electrode FD shown in FIGS. 5 and 6
In P, in order to form a discharge cell S between the Xn and Ym electrodes, it is necessary to provide a partition wall (1) made of an insulator separate from the Xn and Y+o electrodes. There was a slight problem that the formation was complicated in terms of production.

The present invention was made in view of the above-mentioned problems, and an object of the present invention is to provide a vertical electrode FDP in which the formation of partition walls is simplified.

[Means for Solving the Problems] The FDP according to the present invention has vertical X and Y electrodes that generate display discharge between adjacent parallel discharge surfaces arranged alternately with a discharge interval of d, and A conductor partition part is integrally provided on the parallel discharge surface of at least one of the X and Y electrodes, and the distance between the tip end surface and the other electrode surface is dl, which is shorter than the above-mentioned d1. The device is characterized in that a display discharge cell is formed between the X and Y electrodes.

[Function] Approximately perpendicular to the opposing inner surface of the back plate (substrate), vertical Xff1 poles and Y electrodes that generate display discharge between adjacent parallel discharge surfaces are formed alternately with a discharge interval of d. . This X
, when forming the Y electrode, a conductor partition part is provided on the parallel discharge surface of one or both of the X and Y electrodes so that the distance between the tip surface and the other electrode surface or the other tip surface is dl (<d). Protrude in one piece.

The above d and dl correspond to the discharge voltage V2 (> v i) in FIG. 4, which shows the relationship between the discharge interval and the discharge voltage. If a discharge voltage that satisfies (for example, the voltage shown in the shaded area in Figure 4) is applied, a display discharge will occur between the X and Y electrodes, and the conductor partition of one of the X and Y electrodes will be generated. between the other electrode or x
, no discharge occurs between the conductor partitions of both the Y electrodes.

[Example] Figures 1 and 2 show an example of the present invention.
In these figures, (3) and (4) are a front plate and a back plate of glass provided oppositely. The front plate (3)
A phosphor M(5) is coated on the opposing inner surface. A plurality of rows of write electrodes are provided on the opposing inner surface of the back plate (4).
. . WQ-WQ, WI2+1, . . . are thick-film printed with conductor paste. the write electrode W Q-1,
A dielectric layer (2) printed with glass insulating paste is provided on the upper surface of WQ, WQ+, . hand,
A plurality of rows of vertical X electrodes and Y electrodes are provided alternately to generate display discharge between adjacent parallel discharge surfaces. The X and Y electrodes are.

For example, it is formed by laminated printing of conductive paste. The parallel discharge surfaces of each of the X and Y electrodes are provided with a conductor partition portion (6) whose tip surfaces are spaced at a distance of dl (<di);
(7) are integrally protruded, and these conductor partition parts (6)
(7) is the write electrode WQ-I WQ, WQ □
A matrix-like discharge cell group S is formed between the X and Y electrodes corresponding to the intersections of the X and Y electrodes. The distance is dl, and dl is the discharge voltage □ which gives the minimum value of the curve P showing the relationship between the discharge interval and the discharge voltage shown by the solid line in FIG. 4, and the discharge ftff1 which is larger than this discharge voltage v1.
It is selected in accordance with the pressure V2 (>v) and is changed by changing the gas pressure sealed in the discharge cell S. For example, if the gas pressure is reduced, the change will correspond to the curve Q shown by the dotted line in FIG.

The peripheral edges of the front plate (3) and the back plate (4) are sealed by a side plate (not shown), and a vertical electrode FDP is formed by filling discharge gas after evacuation. When this vertical electrode FDP is moved, X.

When a discharge voltage IV1<V<V2) is applied between the Y electrodes and a signal is applied to any one of the write electrodes WQ-I, WQ+I, etc., a signal is generated corresponding to the intersection of these electrodes. A display discharge is generated between the parallel discharge surfaces of the X and Y electrodes facing one discharge cell S, and the phosphor layer (5) of the discharge cell S emits light by the ultraviolet rays generated by this discharge.

At this time, the discharge voltage V is also applied between the conductor partition parts (6) and (7) that partition the discharge cells S that emit light.

This voltage V is the distance d2 between the conductor partitions (6) and (7).
Since the discharge voltage v2 of this conductor partition part (6
) (7) No discharge occurs between.

In the above embodiment, the conductor partition portion protrudes 5 by the same length (+d1 or less) from each of the parallel discharge surfaces of the x and y electrodes, and its tip surface is parallel to the parallel discharge surfaces.
The present invention is not limited to this, but the conductor partition portion (6a)
(7a) is inclined from one side of the adjacent discharge cells S to the other, as shown in FIG. may be formed.

In this case, the amount of ultraviolet light leaking from one discharge cell S to the other discharge cell S is reduced, and crosstalk in color display etc. can be reduced as much as possible.

In the embodiment, the conductor partitions (6), (7), (6a)
(7a) is formed integrally with each of the X and Y electrodes in the same pattern shape to facilitate manufacturing, but the present invention is not limited to this, and at least It is sufficient if it is integrally provided on one of the electrodes. Furthermore, even if they are formed integrally on each of the x and y electrodes, they do not have to have the same pattern shape. For example, as shown in FIG.
Conductor partitions (6) and (7), (6a) and (7) in Figure 3.
The protruding lengths of a) may be different.

[Effects of the Invention] The FDP according to the present invention has a parallel discharge surface of at least one of the vertical X and Y electrodes that generate discharge for one display as described above, and an X, Y for display between the electrodes. Since the conductor partitions for forming the discharge cells are integrally provided, unlike the previously proposed vertical electrode FDP, there is no need to provide a partition wall made of an insulator separate from the X and Y electrodes. This makes it extremely easy to manufacture partitions for forming discharge cells. Furthermore, compared to the conventional opposed electrode discharge type FDP, the vertical electrode FDP has the advantage of having a wider discharge space, higher luminance per luminescence, and better luminous efficiency per luminescence.
