Description

Detailed Description of the Invention The present invention provides a two-dimensional shift method having a write line in which information is written in the horizontal direction by a self-shift function of the discharge spot, and a display line in which the contents of the write line are shifted in the vertical direction and displayed. It concerns possible improvements to gas discharge panels.

As a self-shifting gas discharge panel that has a discharge spot shifting function and an electrode configuration that does not create a crossover part for busbar connection, it is connected alternately to two-phase busbars on one and the other substrate. A gas discharge panel provided with electrodes has been previously proposed in Japanese Patent Application No. 82410/1983.

That is, this gas discharge panel has two-phase bus lines Xas Vertical column electrodes xai, xbi and write electrodes We (it
e-1, 2.3""), and the other board 2 is connected alternately to the busbars Ya, Yb of another two phases, and the adjacent two are set as one set, and the horizontal protrusions are provided alternately. Directional row electrodes yaj, ybj (j-1, 2, 3...)
are provided and covered with dielectric layers 3 and 4, respectively, and at is applied to each opposing portion of both electrode portions Xa, xbp yay yb.
The discharge cells are arranged facing each other with a discharge gas filled space 5 in between so that a regular periodic arrangement of discharge cells shown as by c . . . is formed.

However, the self-shifting gas discharge panel of the type shown in Figure 1 above is called a meander electrode type gas discharge panel because the electrode arrangement has a meandering pattern, and it consists of a pair of substrates. Each of these has the advantage of having only electrode groups for two phases, eliminating the need for an insulation crossover for busbar connection, and achieving improved reliability and high resolution.

When performing multi-line display on such a self-shifting gas discharge panel, the number of write electrodes increases in proportion to the number of shift lines, and the number of write drivers must also increase accordingly. , and the number of connections between the gas discharge panel and peripheral circuits also increases.

Therefore, the inventors of the present invention previously created a write line and a display line, and in the write line, while writing from one end, shifted in the horizontal (line) direction, and when writing for one line was completed, the contents of the write line were transferred vertically to the display line. A two-dimensional shift type gas discharge panel that displays information by shifting in the (column) direction was proposed in Japanese Patent Application No. 1983.

A simplified layout diagram of the electrodes in this case is shown in Figure 3, where one substrate has bus lines X, y and X2 as shown by dotted lines.
+ Xl y Electrodes regularly connected to
Provide regularly connected electrodes to y2, and busbar ¥1,
Electrodes connected to busbars Y3 and Y4 are arranged between the electrodes connected to Y2, and each electrode is covered with a dielectric layer and arranged to face each other with a space filled with a discharge gas such as neon.

The write row is formed by an array of discharge cells at opposing points of electrodes connected to bus lines X, , X2, Y1 to Y4, and the display row is formed by an array of discharge cells at opposing points of electrodes connected to bus lines X1, X2, y1, y2. It is formed by an array of cells.

Note that a write electrode is provided at one end of the write row, but is not shown for the sake of simplification.

Further, each electrode has a meandering shape, as shown in FIG. 1, so that the discharge points are arranged in a straight line.

FIG. 4 shows an explanatory diagram of a specific electrode configuration at the boundary between the writing row and the display row of this conventional panel.

That is, A to G are discharge cells in the write row, and a to d are discharge cells in the display row, and during the write operation, the bus lines X1 and X2 are
, Y1, and Y2, the discharge spot is shifted in the lateral direction along the array of discharge cells A-D.

Also, when shifting from the write row to the display row, discharge cell A
, E, F, G, C, D, A, b, c, d, a, b, c.

In this case, the order of application of shift pulses to each discharge cell according to the combination of busbars during a write operation and during a shift operation to a display row is as shown by the circles in Table 1.

In Table 1, by repeating t1 to t4, the discharge spots in the write row are changed to discharge cells D, A, A, B, B, C,
The display rows are shifted in the order of C and D, and in the display row, the discharge spot is fixed at the discharge cell d-a and displayed statically, regardless of the operation of the write row.

When the write row is shifted to the display row due to the completion of writing for one row, the discharge spots occurring in the discharge cells A, D and a, d at time t are at time t6.
In, the bus lines X1, Y,, Y4 and the bus lines Xi, y
Since a shift pulse is applied to 1 and y2, discharge cells A,
Shift to E and ab.

At the next time t7, shift Hals is applied to the bus lines X1, X2, Y4 and X1, x2, y2, so the discharge spot shifts to discharge cells E, F, b, and c.

Similarly, the discharge spot moves from the write line to the display line at time t.
Shift is performed by repeating the operation from 6 to tll.

In this way, conventionally, a discharge point b is provided between the electrodes of the write row bus line X1 and the display row bus line y2 at the junction between the write row and the display row, so that the shift from the write row to the display row is performed. I was doing it.

However, according to this conventional configuration, in order to make it possible to shift from the write row to the display row, generatrix lines X1 and y1 are required at the boundary between these two lines, and due to the relationship and constraints of the electrode arrangement pitch, the electrodes of this generatrix line Since the pattern cannot be made thicker, the resistance at the electrode portion through which the bus bar passes increases, resulting in a reduction in operating margin.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and to provide an electrode configuration in which a bus bar at the boundary between a write row and a display row can be omitted.

Briefly, according to the present invention, a plurality of column electrodes are regularly arranged with busbar connections on one substrate, and a plurality of column electrodes are regularly arranged with busbar connections on the other substrate opposite to the column electrodes.

The present invention aims to provide a novel morph shift type gas discharge panel featuring such an electrode configuration.

Embodiments of the present invention will be described below with reference to the drawings.
