These plates and electrodes are joined together to provide the first and second layers of the gas cell that work together to provide the desired display.

Although this panel works well and has been commercially successful, improvements are always needed to simplify construction and reduce cost.

This invention relates to eliminating the need for a perforated center plate and the associated manufacturing and assembly costs.

Summary of the Invention Briefly stated, a display panel embodying the invention comprises a first
a base plate holding an array of electrodes; a face plate holding a second array of electrodes; a third array of electrodes 7; disposed between the first array of electrodes and the second array of electrodes; Together with one electrode, a first layer scanning cell is formed, and together with a second electrode a second layer display cell is formed.

The third electrode also separates the scan cell and display cell.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIGS. 1-3, there is shown a display panel 10 embodying the present invention, which includes a first insulating plate or base plate 20 of glass, ceramic, or the like.

The base plate 20 has a top surface 40 and a bottom surface 5.
0 as well as a plurality of parallel slots or channels 30 formed in its upper surface 40.

The number of slots 30 is determined by the number and size of characters displayed on panel 10, as will be apparent to those skilled in the art.

A first electrode 60 generally acts as a scanning anode and is located at the base of slot 30.

The first electrode or scanning anode 60 may be a wire or flat metal strip, or may be plated, vapor deposited, or otherwise formed within the slot 30.

Panel 10 also includes a third electrode 70 that generally operates as a scanning cathode and is positioned on the mutually parallel upper surface 40 of base plate 20 at a preferably 90° angle with respect to scanning anode 60. Ru.

Thus, slot 30 allows scanning anode 60
and the scanning cathode TO.

The third electrode or can-door 0 is a flat metal strip and has an upper surface and a lower surface (FIG. 4).

The area where each can-door 0 intersects the scanning anode 60 is
Scanning gas cells 90 are defined, and these cells are arranged in rows and columns.

The strip-shaped cathode 70 is provided with a continuous aperture 100 extending along its length, so that communication from the scanning cell 90 through the cathode 70 to other elements arranged above the cathode 70 is achieved. (described later).

If desired, one aperture 100 may be provided overlapping each scan cell 90, or a series of apertures 100 may be provided such that each scan cell 90 is covered by more than one aperture. good.

Note that each cathode 70 is aligned in a row of scanning cells 90. According to the invention, each cathode γ0 in the form of a strip is
A film or layer 74 of glass or similar insulating material is maintained along its edges, and the strip is placed in position with the insulating edges abutting each other.

This provides effective spacing between adjacent cathodes 70 and prevents light that may appear below the lower surfaces of cathodes 70 from passing upwardly between the cathodes.

Thus, insulating layer 74 is preferably opaque.

As shown in FIG.
and may have any suitable width.

Other shapes may be used if desired.

For example, as shown in FIG.
It may extend above and below, respectively, upper and lower surfaces 73 and 75 of cathode 70 .

To ensure that no glow appears between the strips of cathode, the adjacent edges of cathode 70 overlap each other, as illustrated in FIGS. 6 and 7. You can.

In this case, the overlapping portion may be thinned so that the strip-shaped cathode 70 lies flat, as shown in FIG.

However, since the strip of cathode 70 is quite thin, such a shape may not be necessary.

In any case, all contacting parts are suitably insulated from each other, for example by having an insulating layer γ4'' extend over the top and bottom surfaces of cathode 70 near the edges of cathode 70. will be done.

If desired, on only one edge of each cathode 70,
An insulating layer 74'' may be provided as shown.

Panel 10 is completed by faceplate 150, which is similar to baseplate 20 and includes a plurality of slots 154 in which a second electrode or display anode 130 is secured to the lower surface.

Slot 154 and display anode 130 are provided parallel to and overlapping slot 30 of base plate 20 and scanning anode 60, respectively.

The display anode 130 and cathode 70 intersect each other, and each area of intersection defines a display cell 157.

In panel 10, plays) 20, 110 and 15
0 are sealed together at their edges, such as by a glass frit, forming a seal 170 as shown in FIGS. 2 and 3.

To conveniently form this seal, face plate 150 and base plate 20 are typically made somewhat larger than center plate 110.

The panel 10 may also contain an ionized gas such as argon, neon, xenon, and preferably a Penn of such gas.
ing mixing and a small amount of mercury vapor to minimize cathode sputtering.

The gas is supplied at a suitable pressure for the intended purpose.

The gas may be introduced by tubing (not shown) suitably secured to the panel, or the gas may be introduced in any other manner.

One convenient way to create panel 10 is to
No. 383,827, filed July 30, 1973.

In accordance with this method, the strip cathode 70 is formed from a continuous ribbon wrapped around the base plate 20 of the panel from a suitable reel.

In this configuration, the rotatable four-sided axle has at least four
One plate 20 (holding the wire 60) can be supported and a strip can-door 0 is arranged to be wound onto it from a reel.

After the cathode 70 is wound, there is still a plate 2 on the mandrel.
0, the faceplate 150 holding its display anode 130 is assembled with each baseplate 20, and the assembly is sealed together and removed from the mandrel.

The cathode ribbon is then cut to form separate cathode strips and force the panels apart for processing into finished products in a conventional manner.

A laser is used to drill an aperture 100 in the cathode 70 at certain times during processing of the panel.

Using a modification of the invention illustrated in FIG. (see Figure) and the desired spacing between scanning anode 60 and display anode 130, and between each of them and cathode 70, is provided by an insulating layer 74' on cathode 70.

Panel 10' thus includes a base plate 20' having a flat top surface on which scanning anode 60 is positioned and secured in any suitable manner.

Cathode 70 has a lower surface 75 disposed adjacent scan anode 60, which contacts insulating layer 74'.

Also, the face plate 150' and the display anode 1
300 assembly is disposed adjacent the upper surface 73 of the cathode 70 and includes the display anode 130 and its insulating layer 74.

Base plate 20' and scanning anode 60, and face plate N50' and display anode 130, may be formed as separate assemblies, with electrodes joined to their respective plates, and then cathode 70.
It will be appreciated that they may be joined together, with the two elements suitably disposed between them.

The principle of this invention is self-scan (5ELF-8CA
N) particularly applicable to display panels, and the construction and operation of such panels are disclosed in co-pending United States Patent Application No. 2551, filed May 19, 1972;
It is detailed in issue 33.

However, the principle of the electrode structure taught here is
It may also be used in other types of devices.

Briefly, panel 10 (and 10') operates as follows.

As already mentioned, cathode 70 and scan anode 60 form scan cell 90; cathode 70 forms scan cell 90;
Define a column of 0s and align with it.

Further, cathode 70 and display anode 130 form display cell 157.

In operation of the panel, the scan cells 90 are energized column by column by applying an actuation potential to all scan anodes 60 simultaneously and to each of the can-doors 0 sequentially.

At the same time, an information signal is applied to the display anode 130 according to the information provided, and where the appropriate signal appears when the scan cell 90 of each column is energized, a glow is transmitted from the scan cell 90 to the aperture 100 of the cathode 70. The display cell 157 moves to the related display cell 157 via the display cell 157, and the display cell 157 emits glow light.

This operation is repeated for each row of cells in turn, and at such a rate that an apparently stationary but changeable message appears between the energized display cells.
