ものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a so-called self-shifting gas discharge panel having a discharge spot shifting function, and in particular improves the arrangement position of write electrodes in order to improve writing accuracy. .

を封入することにより構成されている。A meandering electrode type self-shift gas discharge panel that has already been put into practical use uses a plurality of electrode groups arranged regularly in order to define a fixed shift discharge point array and a writing discharge point at one end of the shift discharge point array. The array of discharge points is constructed by forming an electrode pattern on a transparent glass plate, covering it with a dielectric layer, overlapping them with a narrow space between them, and sealing in gas.

かさなりによって構成されている。However, in such a gas discharge panel, it is important that when a write voltage pulse corresponding to write information is applied to the write electrode, the first discharge spot is reliably generated regardless of the previous state. Among the discharge points formed by the substrate, the shift discharge point array is formed by the intersection of two sets of shift electrode groups, while the write discharge points are formed by the overlap with the write electrode at the end of these shift electrodes. It is configured.

に対応する書込み電圧の範囲が減少する欠点があった。Therefore, a change in the electrode facing area occurs due to an error in the overlapping position of both substrates or a deviation in the accuracy of the electrode pattern. In the former case, this area change has little effect on the shift voltage characteristics, but in the latter case, this effect is large. This has the disadvantage that the range of write voltages corresponding to the shift voltage is reduced.

Our goal is to provide products with a high yield in the manufacturing process.

してかくことを提案するものである。The present invention provides a voltage that produces a normal shift discharge by a combination of pulsed discharges applied to opposing electrodes in a discharge point array formed by opposing a group of electrodes provided on a pair of substrates with a certain space between them. In other words, the range of the write voltage that produces the initial write discharge spot that becomes the source of the shift voltage for the settable range of the shift voltage, the so-called write voltage margin, is the range between the write electrode that is pressed at the write discharge point and the outermost shift electrode provided opposite thereto. Focusing on the fact that there is a correlation in the area facing the electrode, in order to prevent the voltage margin from decreasing due to variations in the facing area, the position of the write electrode is shifted in advance to the base line side where it is less affected by positional deviation. This is a proposal.

Above, the two groups of electrodes 2 on the Y side are arranged alternately in parallel, and the bus lines X1. Another two groups of X electrodes 5 led out to X2, a write electrode W facing the outermost Y electrode y11, and a plurality of negative marks (not shown) facing the alignment mark on the Y side are accurately etched by exposure etching. It is set up as a pattern.

それらの間の空間にガスを封入したものである。The general structure of a meandering electrode type self-shifting gas discharge panel is that each electrode is coated with a dielectric material on these two electrode substrates 1 and 2, and the shift electrodes on the X and Y sides are arranged in predetermined positions as shown in FIG. After assembling with a predetermined space apart with the alignment cross mark as a reference so that they face each other at the relative position,
The space between them is filled with gas.

発生する。However, in the actual manufacturing process, there may be errors in the electrode pattern due to expansion and contraction of the electrode forming film, misalignment of the cross marks, or temporal and spatial unevenness in the melting and settling of the sealing glass or solidification during the sealing process. It is difficult to avoid alignment errors due to minute deviations of the substrate caused by
This causes variations in the facing area of the electrodes from panel to panel.

This shows a case where a shift occurs and the opposing area of the write discharge point W between the outermost shift electrode yix and the write electrode W is reduced.

み放電点の対向面積が著しく変化する。Since the shift discharge point is formed by the cross-opposed portions of the X electrode and the Y electrode, there is relatively little change in the opposing area due to alignment errors, but the write discharge point is formed by the linear write electrode W and the outermost shift electrode. y1□, the opposing area of the write discharge point changes significantly due to a shift in the width direction of the write electrode W.

によって変動しその関係を第５図により説明する。In the self-shift gas discharge panel, the write discharge point W is applied by applying a write voltage to the write electrode W.
A pilot discharge is caused to occur in the write discharge point W, and then a shift voltage is sequentially applied to the four-phase shift discharge point array constituted by two groups of Y electrodes and two groups of X electrodes, starting from the discharge point closest to the write discharge point W. A predetermined discharge pattern is displayed in the shifted discharge point group by the shift operation, but the settable range of the write voltage and shift voltage for such a shift operation varies depending on the electrode facing area, and the relationship is shown in Fig. 5. explain.

電圧の下限をＡ上限をＢとする。That is, the horizontal axis shows the write voltage V, and the vertical axis shows the shift voltage Vs, and the lower limit of the write voltage for an arbitrary shift voltage v8 is set to A, and the upper limit is set to B.

なわないように設定しなければならない。In this case, the amount of displacement of the write electrode is such that the electrode center does not exceed the upper edge position of the outermost X electrode adjacent to the electrode, so as not to impair the discharge coupling between the write discharge point and the starting edge shift discharge point. Must be set to .

果がある。According to the present invention, compared to the conventional meandering type self-shifting gas discharge panel, the pattern of the electrode group provided on each substrate is improved, so that it is possible to prevent a decrease in the write voltage margin due to alignment error. The above-mentioned margin is ensured even if the electrode pattern is misaligned due to this or the alignment is misaligned during the assembly and sealing process, and as a result, it is effective in reducing variations in product quality and improving assembly work efficiency.
