ていた。 One type of AC-driven gas discharge panel is a panel called a surface discharge type or monolithic type. This type of gas discharge panel is known, for example, from JP-A-Sho.
As is well known from Publication No. 47-12, an X electrode and a Y electrode are disposed only on one of a pair of substrates that are placed opposite each other with a gas-filled space in between. The feature is that a horizontal discharge is generated along the substrate surface in the vicinity of the intersection. However, according to such a configuration, the requirement for the gap accuracy between a pair of substrates is significantly relaxed, and an ultraviolet-excited phosphor is added to the inner surface of the cover substrate to allow conversion of display colors and multicolor display. This has the advantage of being easy to perform, but on the other hand, since both the X and Y electrodes must be placed on a single substrate, it is difficult to improve resolution compared to a panel with a facing electrode structure. The use of horizontal discharges along both directions inevitably leads to stronger coupling between adjacent cells (discharge points), which also hinders the improvement of resolution in terms of preventing erroneous discharges due to excessive plasma coupling. .

This is an attempt to improve and obtain a sharp discharge spot.

It becomes possible to generate This discharge is caused by the selected
When a predetermined discharge starting voltage is applied between the Y electrodes, this is caused by the electric field E leaking into the gas space 11 at the intersection of these electrodes, and the electric charge associated with this discharge is subsequently transferred to the dielectric layer corresponding to the discharge point. 17 and is connected by applying an alternating sustain electrode.

止することができる。 Here, the feature of the present invention is that discharge regulating electrode pieces 21 are provided on both sides of the upper layer X electrode 16 at approximately the same distance Df on the insulating film 15 corresponding to the lower layer Y electrode 14. be.
Note that what is important here is the thickness of the insulating film 15.
The design must be such that the ratio of Di to the front distance Df (Df/Di) is 2 or more. When this ratio is set to 2 or less, the specified electrode piece itself functions as a discharge electrode accompanying the lower layer Y electrode. In the case of the embodiment shown in FIGS. 1 and 2, the specified electrode piece is arranged at the center position between two adjacent X electrodes, and is shared by two adjacent discharge points defined by both electrodes. ing. In addition,
In this example, the distance D f between the edge portion of the discharge regulating electrode piece 21 and the edge portion of the X electrode 16 is approximately 40 μm, and the pitch width of the X electrode is approximately 500 μm. However,
As mentioned above, the thickness Di of the vapor-deposited insulating film 15 is about 3μ.
m, the above (D f /Di) is approximately 13.
By providing the discharge regulating electrode piece 21 between the upper layer X electrodes 16 in this way, it is possible to prevent the discharge spot from tending to extend in the direction in which the lower layer Y electrode 14 extends.

ずることになる。 That is, in the above-mentioned surface discharge type gas discharge panel, among the X and Y electrodes arranged in two layers, the portion Sa of the lower Y electrode 14 facing the upper layer X electrode 16 is dotted as shown. It is in the shadow of the upper layer X electrode 16 and is shielded from the electric field E leaking into the gas space 11, and does not contribute to discharge. On the other hand, AC discharge between the X and Y electrodes occurs in such a way that each electrode surface alternately acts as a cathode, producing cathode glow, but in this case, the current when the polarity of the applied voltage is reversed is the same. As far as possible, the area where cathode glow occurs is equal on both the X and Y electrode surfaces. Therefore, in this type of panel where the widths of the X and Y electrodes are the same, when the lower layer Y electrode 14 side serves as a cathode and discharges, the upper layer X electrode 1
A discharge is generated by spreading in the extending direction of the Y electrode 14 by an amount corresponding to the area of the discharge invalid portion Sa immediately below the Y electrode 14.

By providing a floating discharge regulating electrode piece 21 between the electrodes 16, Y
The electric field that is unduly diffused in the direction of extension of the electrode is attracted to the electrode piece, and as a result, the extension of discharge in the direction of extension can be suppressed. FIG. 3 is a cross-sectional view of the electrode supporting substrate side schematically showing the state of discharge, and the operation of suppressing expansion of discharge will be explained in more detail according to this diagram. In this figure, if a voltage is applied between the X and Y electrodes so that the lower layer Y electrode 14 becomes a cathode state, then the parabola A in the figure
Symmetrical lines of electric force are generated on both sides of the X electrode 16 as shown in FIG. In this case, since the discharge regulating electrode piece 21 is arranged approximately in the center between the upper layer X electrodes 16,
- The electric field generated between the Y electrodes is not significantly disturbed. Thus, a discharge occurs near the intersection of the X-Y electrodes where the electric field distribution is highest, and this discharge extends in the direction in which the electric field distribution becomes coarser over time, that is, in the direction in which the underlying Y electrode 14 extends. During this time, on the surface of the dielectric layer 17 corresponding to the Y electrode,
Positive charges are accumulated one after another in a form extending along the extending direction of the Y electrode 14, and are finally accumulated on the surface of the dielectric layer corresponding to the discharge regulating electrode piece 21.
Then, since the specified electrode piece 21 has a floating structure, it is attracted by this charge and the potential state changes from the potential on the lower layer Y electrode side to approach the potential on the upper layer X electrode side. However, since this potential change is in the direction of lowering the effective voltage applied to the gas space, the discharge electric field is thereby suppressed, and as a result, the discharge does not extend beyond the specified electrode piece 21. Referring again to FIG. 1, the hatched portion Sx is the portion that functions as the discharge surface of the upper layer X electrode 16, and the double hatched portion Sx is the portion that functions as the discharge surface of the upper layer X electrode 16.
Sy is a portion of the lower layer Y electrode 14 that functions as a discharge surface. The areas of both parts Sx and Sy are equal,
As a result of the discharge regulating electrode piece 21 preventing discharge expansion corresponding to the area of the electrode intersection Sa, which is an ineffective region on the lower Y electrode side, the lengths of the discharge surface in both the X and Y directions become approximately the same.

る。 Therefore, according to the present invention, discharge spots that generally tend to extend in the stretching direction of the lower electrode can be shaped and sharpened, thereby preventing excessive plasma between discharge points adjacent to the lower electrode in the stretching direction. This is convenient for preventing erroneous discharges due to coupling, reducing the pitch between discharge points, and improving resolution. In addition, according to the panel structure according to the embodiment described above, the discharge starting voltage V f could be increased by about 10 volts compared to a normal panel having no discharge regulating electrode piece. Specifically, V f ≒160 volts for the panel of the present invention, and V f ≒ 160 volts for the conventional panel.
150 volts and the minimum sustaining voltage for both panels
Both Vsmin are about 130 volts. However, with Vf
The operating voltage margin determined by the difference from Vsmin is 20
Increases from volts to 30 volts for a 50% increase.

That's fine. According to this multicolor display panel, since there is little mutual interference between adjacent discharge points, it is possible to provide a high resolution multicolor display without crosstalk.

In an AC-driven surface discharge type gas discharge panel in which a layer of electrodes is arranged, discharge regulating electrode pieces of a floating electrode configuration are placed directly above the lower layer electrode and on both sides of the upper layer electrode on the surface where the upper layer electrode is arranged. are arranged in a nearly equidistant relationship, and the ratio (Df/Di) of the thickness Di of the insulating film between the two layer electrodes and the distance Df between the upper layer electrode and the discharge regulating electrode piece is set to 2 or more. This feature is extremely useful for improving resolution by preventing the abnormal spread of the discharge spot in the direction of extension of the lower electrode, which is characteristic of this type of surface discharge panel.

ことができる。 Incidentally, in Japanese Unexamined Patent Application Publication No. 1098/1983, an electrode pad with a floating structure that is capacitively coupled with the lower layer electrode is provided at a position close to one side of the upper layer electrode, and a positive electrode pad is provided between the upper layer electrode and the electrode pad. A surface discharge type gas discharge panel that generates a discharge has been proposed. However, with this panel structure, discharge occurs only on one side, so the discharge spot is small compared to the display space, that is, the filling factor is small. Therefore, the separation of discharge spots at adjacent discharge points becomes large, resulting in a display with low resolution. On the other hand, in the panel structure of the present invention, since discharge spots are generated symmetrically on both sides of the upper layer electrode as described above, the filling factor can be made extremely high.
