Description

DETAILED DESCRIPTION OF THE INVENTION [Summary] The present invention describes an electrode extraction method for reducing the number of electrode extraction on a substrate to a medium number in a surface discharge gas discharge panel having three electrodes. .

[Industrial applications]

The present invention relates to an improvement in the manufacturing process of a matrisk type surface discharge type gas discharge panel among gas discharge panels that have come to be widely used for information display, and a panel electrode lead wire in consideration of compatibility with a panel external drive circuit. Applies to withdrawal methods.

[Conventional technology]

The present inventors have disclosed a display panel related to the present invention in Japanese Patent Laid-Open Nos. 55-113237, 57-78751, and 62-2.
2352 (Japanese Patent Application No. 60-160952).

FIG. 2 shows one method of extracting electrodes of a surface discharge gas discharge panel, which is one of the conventional examples.

In FIG. 2, A is an address electrode that is insulated from each other and is also insulated from other sustain electrodes, and X and Y are a pair of mutually insulated sustain electrodes.
3,..., M and N are identification numbers of the respective electrodes.

The upper electrode of the pair of horizontal electrodes indicated by a circle which is a representative portion of the display in the center of FIG. 2 is a Y electrode,
The electrode located at the bottom is the X electrode. Thus, subscript 1
A sustain electrode for maintaining a display discharge is formed by a pair of electrodes shown in FIGS. A driving voltage is sequentially applied to the sustain electrodes from the upper side to the lower side in the figure, and the display is scanned. Most commonly, the electrode take-out portions are taken out individually for each electrode as shown in FIG.

In this case, N extraction terminals are arranged on both sides of the substrate.

Considering this, N on a single substrate shown in FIG.
When the pair of counter electrodes are taken out separately on the left and right, the number of electrodes is 2N
When N is a large number, the number of terminals becomes very large, and the space of the terminal portion becomes narrow.

[Problems to be solved by the invention]

The panel of the present invention has a problem of extreme convergence of the extraction electrode at the end of the substrate. Normal two-electrode type with N electrodes
In an XY orthogonal matrix panel, the number of electrodes is N on one substrate, but in the three-electrode surface discharge panel of the present invention, M address electrodes and 2N display electrodes are formed on one substrate. Exists.

The number of display points is the number M of address electrodes A and the number N of sustain electrodes Y.
(= The number of X sustain electrodes), which is the same as the product of M and N in the case of the simple matrix type. However, in the case of this method, the number of extraction electrodes is paired compared to the simple matrix type. It can be said that the number is equal to the number of the sustain electrodes N. It is narrow to fit the 2N ends of the sustain electrodes on the two sides of the panel on the extension of the display electrodes, and the electrodes are congested.

[Means for solving the problem]

In order to not only reduce the number of electrodes that take out the congested display substrate by using the common connection often used in the matrix addressing method but also to correct the bias of the number of existing electrodes, draw out the lead lines from multiple groups that made the common connection. , And take them out in different directions alternately. In other words, the occupied locations of the electrode terminals are evenly distributed on both sides of the panel.

(Operation)

Commonly connected and reduced extraction electrodes are distributed and distributed to the left and right ends in order, and the other plurality of electrodes that are not commonly connected are distributed and derived to the opposite end. When n lines are commonly connected in this way, the density is averaged and reduced by the amount of thinning out the electrodes at both ends. As compared with the case of FIG. 2 in which the number of extraction electrodes is 2N,
(+ 1 / n) N lines. By this distribution change, the degree of electrode denseness is averaged.

〔Example〕

 Examples of the present invention will be described below.

FIG. 1 shows one preferred embodiment of the present invention. First
Of the electrode pairs 印 as the display portion in the center of the figure, the electrode drawn on the upper side is the Y electrode, and the electrode drawn on the lower side is the X electrode. Both are sustain electrodes for maintaining the display discharge. A drive voltage is sequentially applied to the sustain electrodes from above, and the display operation is scanned. At this time, only X electrode, X1, X2,
· Like X (N / 2), common connection is made every two adjacent electrodes to reduce the number of extraction electrodes, and Y electrodes are Y1, Y2, Y3, Y4,
・ Because of sequential scanning type driving like YN, the number is the same as before without common connection. Assuming that the total number of electrodes is N, the number of X electrodes is (N / 2), and the number of Y electrodes is N as it is. Therefore, the total number of sustain electrodes taken out is (1 + 1/2)
N.

At this time, the lead line of the electrode X1 in which the number of lead lines is reduced by half is assigned to the left end, and instead, the Y electrode belonging to the same group is
If the assignment of the lead lines of Y1 and Y2 to the opposite right end is alternately repeated left and right, the number of electrodes at the left and right ends decreases on average due to the decrease of the X electrode lead lines, and FIG. , The number was reduced to (1 + 1/2) N lines, and the total number of lines was averaged right and left.

In addition to this embodiment, one of the electrode groups is a number larger than two,
An extraction method in which n lines are commonly connected, the lead line is assigned to the left end, and the other n electrode lead lines belonging to the same group are assigned to the opposite right end. Are also included in the present invention.

〔The invention's effect〕

According to the present invention, not only the electrode path congestion at the electrode end portion of the conventional surface discharge gas discharge panel is alleviated, but also an electrode arrangement suitable for bonding to an external circuit of the panel, and an electrode extraction form suitable for practical use became.
