Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention is directed to a vertical ff1ti plasma display panel (hereinafter simply referred to as F
(described as DP).

[Prior art] 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 narrow, the luminance is low, and the luminous efficiency is poor. In order to solve this problem, the present applicant proposed in Japanese Patent Application No. 62-217403 a vertical electrode FDP in which the discharge surface of the discharge electrode is approximately perpendicular to the substrate. did.

[Problems to be Solved by the Invention] As shown in FIGS. 4 and 5, the above-mentioned vertical electrode FDP is a multi-row vertical electrode that generates display discharge between adjacent parallel discharge surfaces. ..., Xn, That's what happens. (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.

However, the vertical electrode FD shown in FIGS.
In P, a write electrode WQ is required in addition to the vertical electrodes Xn-Ya, so there is a slight problem that the structure of the drive circuit becomes complicated.

The present invention has been made in view of the above-mentioned problems.

It is an object of the present invention to provide a vertical electrode FDP that can simplify the drive circuit by reducing the number of electrodes connected to the drive circuit.

[Means for Solving the Problems] The FDP according to the present invention includes a plurality of rows of vertical electrodes that generate display discharge between adjacent parallel discharge surfaces.

The vertical electrodes in every other row are used as X electrodes, and the vertical electrodes in the remaining rows are divided into vertical electrodes corresponding to each column of the display discharge cell group. It is characterized in that it is coupled to a Y electrode that intersects with the electrode group.

[Function] Group 1 is formed between the predetermined x and Y electrodes of the X electrode group and the Y electrode group.
! When a voltage is applied, a display discharge occurs between the parallel discharge surfaces of the vertical electrode on the xit pole side and the divided vertical electrode connected to the Y electrode, which form a discharge cell at the intersection of the X and Y electrodes. Then, the corresponding discharge cell discharges and emits light. That is, X,
Y matrix driving becomes possible.

[Example] Figures 1, 2, and 3 show an example of the present invention. In these figures, (3) and (4) are glass front plates provided oppositely. and the back plate. A phosphor layer (5) is coated on the inner surface of the front plate (3).

On the inner surface of the back plate (4), there are two Y-shaped holes 0.0. a and Ym-11b, Ym, a
and Ym, b, Yn++1. a and YI11+0. b,
...The Y electrode group is printed with a thick film of conductive paste. Said Yt! A dielectric layer (2) printed with glass insulating paste is provided on the upper surface of the electrode group, and this dielectric layer WI (2) has a dielectric layer (2) formed on the upper surface of the pair of Y electrode groups alternately. The window hole (6) for the coupling conductor is located at a ratio of one for every two discharge cells. The dielectric layer (2
), multiple rows of vertical electrodes that generate display discharge between adjacent parallel discharge surfaces are formed by laminated printing of conductive paste, and of these multiple rows of vertical electrodes, every other row The vertical electrodes of Xn, Xn4. , . . . electrodes, and the vertical electrodes in the remaining rows are divided into columns corresponding to the discharge cells S to form divided vertical electrodes (7) (7) . . . (7) (7)... becomes the property of the Y electrode group through the window hole (6)... of the dielectric M(2) for each column of discharge cells S,... They are electrically coupled alternately to one side and the other side of the Y electrode group (for example, Y Ill, a and Ym, b, . . . ) in different ways. On the upper surface of the dielectric M (2), a partition wall (11) made by laminating and printing a dielectric paste is formed, and a matrix-like discharge cell group S, S, ... is formed. .

The peripheries 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 the evacuation machine discharge gas.

When driving this vertical electrode FDP, when sequentially applying a scanning pulse to one of the X electrode group and the Y electrode group and a display pulse to the other, the X electrode (e.g., Xn electrode) and the Y electrode group (e.g., Ym-,,a, Ym+1.a...
Divided vertical electrodes (7) (7)... A display discharge is performed between any adjacent parallel discharge surfaces, and the corresponding discharge cells S, S, etc. discharge and emit light.

In the embodiment described above, the Y electrode group is formed by a group of two electrodes (for example, Y If, a and Y m, b) that are alternately combined with a plurality of divided electrodes in a column to be combined in different ways. Although the definition of the display is increased, the present invention is not limited to this, but may be formed by a group of one electrode (for example, Ym) sequentially combined with a plurality of divided electrodes in the column to be combined. Good too. In addition, in the case of this one, if a space is provided between the tip surface of the X electrode group and the phosphor layer on the front panel so that ultraviolet rays can hit the phosphor layer on the top surface of the X electrode group, display unevenness can be reduced. becomes less.

[Effects of the Invention] Since the FDP according to the present invention is configured as described above, an electrode group for display selection is not required compared to the previously proposed vertical type TFI PDP, so the electrode structure is simplified. X
, Y matrix driving becomes possible, and the structure of the driving circuit can be simplified.

Furthermore, compared to conventional counter-electrode discharge type FDP.

The vertical electrode FDP can have the advantages of a wide discharge space, high luminance, and high luminous efficiency.
