Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a display device suitable for use in various information boards, signboards, and the like.

[Prior Art] Conventionally, display devices have been used in which display parts such as guide symbols are drawn on a transparent plate made of synthetic resin material, glass, etc., or holes are formed in the transparent plate and electrical display elements are inserted. . This kind of display device is transparent because the parts other than the display part are transparent.
For example, when used as information boards at reception counters, etc., it does not feel oppressive.

It does not hide the other person's face, and it has the feature of creating a clean design without any clutter.

[Problems to be Solved by the Invention] However, since the two display parts are fixed in the above-mentioned display device in which the display part is drawn on the transparent plate, and the display part does not have a three-dimensional effect, it cannot be used for a long time. It is difficult to attract the viewer's attention or give them a sense of surprise.

Furthermore, when an electric display element is inserted, the electric wiring cords of the power supply means are tangled on the back side of the transparent plate, making it unsightly.

SUMMARY OF THE INVENTION An object of the present invention is to provide a display device that has a neat design, attracts the viewer's attention for a long time, and can give the viewer a sense of surprise.

[Means for Solving the Problems] In the display device of the present invention, conductive parts for positive electrodes and negative electrodes each made of a conductive mesh formed by a plurality of conductive wires are arranged at a predetermined interval inside a base part made of a transparent electrically insulating material. A hole is provided in a transparent display plate arranged in layers with a distance between the holes, an end of each conductive part reaches the inner wall surface of the hole, and a layer of a conductive material is formed on the inner wall surface of the hole. The electrically conductive portions are provided separately and electrically connected to the ends of each conductive portion.

[Function] In the present invention, conductive parts for positive and negative electrodes, which are made of a conductive mesh formed by a plurality of conductive wires, are layered at predetermined intervals inside a base part made of a transparent electrically insulating material. A hole is provided in the transparent display plate arranged as shown in FIG. The positive electrode terminal and the negative electrode terminal of the electrical display element are separated from the positive electrode conductive part and the negative electrode conductive part, respectively, and connected to the conductive material. Complete electrical coupling can be achieved through the layers. In addition, by inserting an electric display element into the hole of the display device of the present invention and changing the lighting or blinking, it can attract the attention of the caretaker for a long time and give the caretaker a sense of surprise.
It can be suitably used for route guide boards, etc.

[Embodiment] FIG. 1 is a sectional view showing an example in which terminals of electrical display elements are inserted into two display devices of the present invention. In FIG. 1, holes 2 are provided in a conductive transparent display plate 1. As shown in FIG.

On the inner wall surface of the hole 2, the positive electrode conductive portion 3a and the positive electrode terminal 5a of the electrical display element 4 are connected via the conductive material layer 6a.

In addition, the conductive part 3b for the negative electrode and the terminal 5 for the negative electrode of the electrical display element 4
b are electrically coupled through a layer 6b of conductive material.

In FIGS. 2 to 4, the positions of the holes 2 provided in the transparent display +,)ij 1 are shown. The position of the hole 2 should just intersect with the conductive part 3. Further, the hole 2 may be a single through hole or a hole with a bottom.

To explain the electrical connection between the conductive part 3 and the terminal 5 of the electrical display element 4, if the hole 2 is simply opened with a drill, laser beam, etc., unevenness of the inner wall surface of the hole 2, chips caused by the drill, and dust will be generated. A complete electrical connection is difficult due to adhesion or the difference between the inner diameter of the hole 2 and the outer diameter of the terminal 5 of the electrical display element 4. In addition, when electrically connecting by soldering, if the inner diameter of the hole 2 is small (1, for example, 5 mm or less), it may be difficult to solder the conductive part 2.
If the resin fiber 1 is made of, for example, polyester fiber plated with metal, the conductive portion 3 will melt due to the heat of the solder or soldering iron, making it impossible to form a complete bond.

In the present invention, a layer 6 of a conductive material is deposited on the inner wall surface of the hole 2 as shown in FIG. 5 in order to easily obtain a perfect electrical connection and a beautiful design.

The layer 6 of the conductive material may be attached by plating the inner wall surface of the hole 2, or by applying a conductive adhesive or a conductive paste, but in any case, the inner wall surface of the hole 2 may be coated with a conductive adhesive or a conductive paste. It is sufficient if the layer is evenly distributed.

Even if the terminal 5 of the electrical display element 4 is inserted directly into the hole 2,
The positive and negative terminals of the terminal 5 and the conductive part 3 cannot be separated, resulting in a short circuit.

Therefore, in the display device of the present invention, as shown in FIG. 6, the inner wall surface of the hole 2 corresponding to the center part between the eyebrows of the conductive parts 3a and 3b is scraped, and the layer 6 of the conductive material in this part is completely scraped off.

The layer 6 of 2gL electrical material is thus completely electrically separated into a portion 6a coupled to the conductive portion 3a and a portion 6b coupled to the conductive portion 3b. Therefore, the conductive portion 3a and the conductive portion 3b can be completely electrically separated within the hole 2.

In this way, a method for scraping the inner wall surface of the hole 2 corresponding to the central part between the conductive parts 3a and 3b requires a blade 7 with an eccentric shaft, as shown in FIGS. 7 and 8, for example. Place it on the spot and rotate it with a drill press etc. to cut it.

Another method for forming the conductive material layers 6a, 6b is to provide a hole 8 having a diameter smaller than the outer diameter of the terminal 5 of the electrical display element 4, for example as shown in FIG. Only the portion of the inner wall surface where the conductive portions 3a and 3b have been reached is expanded to a predetermined diameter, and a layer 6 of a conductive material is adhered to the inner wall surface as shown in FIG. Furthermore, only the hole 8 portion is ground with a drill or the like, the layer of conductive material adhering to that portion is completely scraped off, and the diameter of the hole 8 is adjusted by attaching the layer 6 of the conductive material as shown in FIG. Expand to the inner diameter of hole 2.

Thus, similarly to the method described above, 6 connected to the conductive part 3a
It is completely electrically separated into a portion a and a portion 6b coupled to the conductive portion 3b.

As described above, the completely electrically isolated conductive material layer 6
Since the hole 2 to which the electrodes a and 6b are attached is formed, the positive electrode terminal 5a of the electrical display element 4 is connected to the positive electrode conductive part 3a, and the negative electrode terminal 5b is connected to the negative electrode conductive part 3b in one hole. They can be separated and electrically coupled through conductive material layers 6a and 6b, respectively.

Conventionally, as shown in FIG. 12, the terminals of electrical display elements have consisted of two legs in which a positive electrode terminal 5a and a negative electrode terminal 5b are each separated and attached to the main body.

The electrical display element used by being inserted into the hole of the display device of the present invention is composed of a composite terminal 9 having a positive electrode terminal 5a and a negative electrode terminal 5b in a single direction, as shown in FIGS. 13 to 17. It is something. The positive electrode terminal 5a and the negative electrode terminal 5b are separated by an electrically insulating synthetic resin 110 so as not to cause a short circuit.

FIG. 18 is a perspective view showing an example of a display device constructed using the display device of the present invention, in which legs 11 are provided at the lower end of the bent transparent display plate 1.

The transparent display plate 1 is made of an achromatic or chromatic transparent electric insulating material (resin material) as shown in FIG.

Two conductive parts 3 (
3a, 3b) are buried inside the body. Each conductive part 3a,
3b are arranged inside the base portion 7 so as to form layers at predetermined intervals.

The conductive portion 3 has a diameter or width of 100 μm or less.

Preferably, it is made of a conductive mesh formed of ultrafine strands of 20 μm or less.

As shown in Fig. 2, the conductive mesh is constructed in the form of a net by using ultra-fine strands arranged in parallel as a composite material and incorporating other ultra-fine strands in parallel at right angles to the ultra-fine strands. There is.

Note that the interval between adjacent ultrafine strands is set in consideration of the viewer's sense of transparency. For example, when using ultrafine wires with a diameter of about 100 μm, the interval between adjacent wires is 1
It is desirable to set the distance roughly to about 0 mm or more, and when using ultrafine wires with a diameter of about 20 μm, the spacing between adjacent wires can be set closely to about 1 mm.

Further, the conductive mesh is formed by vapor depositing or plating metal on the surface of two synthetic resin wires formed from metal wires such as gold wires and copper wires.

Further, when the conductive mesh forming the conductive portion 3 is arranged in layers on the transparent display panel.

If the meshes are stacked in the same direction, a moiré phenomenon will occur, the transparency will drop, and the mesh will look complicated, which is not appropriate. On the other hand, when the meshes are overlapped so that their directions form an angle of 45 degrees to each other as shown in FIG. 2, no moiré phenomenon occurs.

That is, the transparent display plate 1 uses a conductive mesh made of ultra-fine wires for the conductive portion 3, and the directions of the mesh are 4
They are stacked at a 5 degree angle to prevent moiré, so the whole can be seen as an achromatic or chromatic transparent object.

In addition, the transparent display plate l has the above-mentioned conductive portion (conductive mesh) 3.
It may be formed by bonding and integrating two base parts made of transparent electrically insulating materials each having one layer embedded therein. Further, the constituent materials of these two base portions may be the same or different.

Furthermore, in the present invention, the conductive part built into the base part is
It may be multilayered to 3JW or more.

9 In the present invention, the conductive portion built into the base portion is 2
Parallel wire groups consisting of the above ultra-fine strands, or st O!
- It may be made of a conductive film or the like deposited with an indium alloy or the like.

Further, in the present invention, the conductive portion may be unevenly distributed near one surface of the base portion. The aspect of the conductive portion within the transparent display panel is as described in detail by the present inventor in the specification of Japanese Patent Application No. 61-282925.

[Effects of the Invention] As described above, in the present invention, a transparent display plate is provided with a hole in which a layer of conductive material is attached to a conductive part for a positive electrode and a conductive part for a negative electrode in a completely separated state. Because it is
When an electrical display element having a composite terminal is inserted into the hole, the positive terminal of the electrical display element is separated from the positive conductive part, and the negative terminal is separated from the negative conductive part, and the electrically conductive material layer is inserted between the positive terminal and the negative conductive part. can be completely combined.

In addition, since the display device of the present invention inserts an electric display element into the hole, if the electric display element breaks down or the display pattern needs to be changed, it must be replaced with a new one or with a different color electric display element. is very easy.

In addition, if an electric display element is inserted into the hole of the display device of the present invention and electrically connected, the electric display element uses a conductive wire as a power supply means that is almost invisible to the viewer's eyes. It is possible to produce an unexpected feeling as if the display element is independently displaying electricity without a power supply means in the transparent space provided by the transparent display board. Furthermore, since the coupling portion can easily hide the surface of the electrical display element, the surface can be designed with a clean appearance. Furthermore, when the hole is a bottomed hole, not only can the surface have a clean design, but also there is no electrical wiring cord on the opposite side.

The opposite side can also be used effectively.
