BEST MODE FOR CARRYING OUT THE INVENTION

 Hereinafter, an embodiment of the present invention will be described with reference to FIGS. In these drawings, the same or corresponding parts are denoted by the same reference numerals.

FIG. 1 is a front view of a color sheet light emitting display device 11 according to a first embodiment of the present invention, and FIG. 2 is an end view of a section taken along line II-II of FIG. The color sheet light-emitting display device 11 displays information such as characters, pictures (graphics), and symbols three-dimensionally on the surface 11a side and emits such information. A plurality of color sheets EL (electroluminescent light emitting devices) 12, 13, 14, 14, 15, 16, 17 of, for example, six colors are laminated in the thickness direction to form a three-dimensional picture 11b or the like with six colors. The outer surfaces of the color sheet ELs 12 to 17 are covered with a pair of front and back transparent films 18a, 18b, and the outer peripheral edges of the pair of transparent films 18a, 18b are integrally formed by thermocompression bonding or the like. It is hermetically sealed.

FIG. 3 is a partially exploded perspective view showing the configuration of these color sheet ELs 12 to 17, and FIG. 4 is a partial longitudinal sectional view thereof. Each of the color sheet ELs 12 to 17 has a light emitting layer 19 composed of a phosphor layer that emits a required color and contains a dye that is substantially the same as or similar to the luminescent color of the phosphor to always exhibit the required color. ing.

Then, a sheet-shaped insulating layer 19 a is brought into contact with the back surface of the light emitting layer 19, and the back surface of the insulating layer 19 a and the surface of the light emitting layer 19 are connected to each current collector 20. A pair of tongue-shaped electrode leads 21a and 21b are sandwiched between a pair of protruding sheet-like front and back electrode sheets 22a and 22b.

Further, the front and back surfaces of the pair of electrode sheets 22a and 22b are covered with a pair of front and back moisture absorbing films 23a and 23b, respectively, and the outer edges of the pair of front and back package films 24a and 24b are heated. It is formed integrally by crimping or the like by crimping or the like, and has a total thickness of, for example, about 1 to 3 mm, and is formed into a flexible sheet. Note that the pair of moisture absorbing films 23a and 23b may be omitted.

The color sheet ELs 12 to 17 emit light of various colors such as blue, green, red, white, and yellow according to the type of the phosphor of the light emitting layer 19, and include a pair of electrode leads 21a. , 21b are connected to an inverter, which is an EL driving device (not shown), and emit light by applying an AC electric field to the phosphor of the light emitting layer 10. In addition, due to the dye contained in the phosphor of the light emitting layer 19, the required color is always exhibited even when the light is not lit.

Then, these six layers of color sheet ELs 12 to 17 are cut out or cut out as needed, and laminated in the thickness direction to form, for example, a three-dimensional solid picture as shown in FIG. 11b.

Next, a method of forming the knitted picture 11b will be described. For simplicity, a part of the method will be described with reference to FIGS.

FIG. 5 is an enlarged front view of a part of the picture 11b, for example, the periphery of the eyeball portion 11c of the profile of the right woman in FIG. 1, and FIG. 6 is a sectional view taken along line VI-VI of FIG. It is.

That is, the eyeball portion 11 c is formed by laminating at least three color sheet ELs of three colors, for example, 12, 13, and 14 in three layers. In FIG. 6, an outer elliptical through-hole 12a showing the outline of the eyeball portion 11c is cut out in the upper color sheet EL12, and the middle color sheet EL13 has a smaller diameter than the outer elliptical through-hole 12a. The inner elliptical through hole 13a of the eyeball portion 11c is cut out concentrically, and nothing is cut out in the lower color sheet EL14.

Next, by concentrically laminating the color sheets EL12 to EL14, the eyeball portion 11c can be expressed by, for example, three colors. Since the whole picture 11b is formed in this way, the picture 11b becomes a three-dimensional picture and the depth can be increased.

FIG. 7 shows the back surface 11d of the color sheet-shaped light emitting display device 11 for displaying the knitted picture 11b, and one end (the left end in FIG. 7) of each of the color sheet ELs 12 to 17 is formed. The figure shows a state in which the sheets are slightly shifted by a predetermined interval in the horizontal direction, that is, the direction orthogonal to the laminating direction of the color sheet-like ELs 12 to 17.

In other words, the width direction (horizontal direction in FIG. 7) dimension of each of the color sheet ELs 12 to 17 is formed so as to be sequentially shortened by a predetermined length a. The pair of electrode terminals 25 and 26 are juxtaposed vertically in a state where they are exposed on the outer surface. The electrode terminals 26 on the anode side (the lower side in FIG. 7) are spaced apart from each other by a predetermined distance b for each of the color sheet ELs 12 to 17 and are insulated from the rectangular electrodes 26a, 26b, 26c, 26d, 26e. , 26f and separately formed, for example, arranged in a horizontal line. Each of the electrode terminals 12a to 17a has a respective one of the projections in which the anode terminals of the electrode lead wires 21a and 21b of each of the color sheet EL12 to 17 project outward from one end of each of the color sheet EL12 to 17 respectively. Each is electrically connected to the end.

On the other hand, the electrode terminal 25 on the cathode side (upper in FIG. 7) is formed in a band shape of a predetermined width, and is integrally formed from the left end color sheet EL12 to the right end color sheet EL17 left end in the figure. Have been. The cathode side electrode terminal 25 has a cathode side of each of the color sheet-like ELs 12 to 17, that is, a ground side of each pair of electrode leads 21a and 21b protrudes outward from one end of the color sheet-like ELs 12 to 17, respectively. Are electrically connected to the respective protruding ends.

One lead wire 27 for grounding is fixed to the outer surface of the strip electrode terminal 25 on the ground side by soldering or the like. Further, for example, six lead wires 28a, 28b, 28c, 28d, 28e, 28f are fixed to the outer surfaces of the respective electrode terminals 26a to 26f on the respective anode sides by soldering or the like, and these six lead wires 28a to 28f are respectively fixed. 28f are tied into a single flat cord. These lead wires 27 and 28a to 28f are electrically connected to respective inverters (not shown) which are EL driving devices.

Accordingly, the sheet-shaped light emitting display device 11 configured as described above can always display the assembled picture 11b on the front surface in color, and can appropriately turn on the colored sheets EL12 to 17 by appropriately lighting. 11b can be displayed by emitting light in color.

Further, since the color sheet ELs 12 to 17 are laminated in the thickness direction, each pair of electrodes of the color sheet ELs 12 to 17 is provided at the same side end of each of the color sheet ELs 12 to 17. Electrode terminals 25, 26a to 26f electrically connected to the leads 21a, 21b are formed, respectively, and can be exposed to the outside.

Therefore, even if the number of stacked color sheet ELs 12 to 17 increases, all of these electrode terminals 25, 26 a to 26 f are at the same side end of the color sheet ELs 12 to 17. Lead wires 27, 28a to 28f can be easily and quickly connected to these electrode terminals 25, 26a to 26f by soldering and the like, and a plurality of lead wires connected to these electrode terminals 25, 26a to 26f can be obtained. Since all the lead wires 27, 28a to 28f can be drawn in one direction on the same side, the wiring can be routed easily. As a result, the risk of erroneous connection when connecting the lead wires 27, 28a to 28f to an inverter or the like of the EL driving device can be reduced.

Further, by increasing the number of layers of the plurality of color sheet ELs 12 to 17, the method of expressing the assembled picture 11 b and the graphic can be enriched. Since it can be expressed in different ways, the depth as a picture can be increased, and the range of application to arts and crafts can be expanded.

Further, since the outer surfaces of the plurality of color sheet ELs 12 to 17 are integrally covered with a pair of transparent films 18 a and 18 b and sealed, the moisture proof properties of the respective color sheet ELs 12 to 17 can be improved. In addition to the above, it is possible to fix the information display portion such as characters and figures formed by the plurality of color sheet ELs 12 to 17 to prevent the information display portion from being displaced. Can be handled as one part, so that the workability of assembling the color sheet ELs 12 to 17 can be improved.

The electrode terminals 25, 26 a to 26 f are respectively disposed on the same side end on the back side of each of the color sheet ELs 12 to 17, and the respective side ends of the color sheet EL are stacked in the stacking direction. Since the electrode terminals 25, 26a to 26f are exposed to the outside by being shifted in a direction perpendicular to the direction, the lead wires 27, 28a to 28f can be easily connected to these electrode terminals 25, 26a to 26f. At the same time, the direction in which the wires are drawn out can be aligned in one direction, so that the wires can be drawn out and routed very easily, and the wires 27, 28a to 28f are bound in a flat band shape. Therefore, the workability of these wirings can be improved.

Further, since the electrode terminals 25, 26a to 26f of each pair are arranged at the same side end of the color sheet EL12 to 17, each electrode lead 21a on the ground side of each of the color sheet EL12 to 17 or 21b can be electrically connected to each other by the ground-side electrode terminal 25 and can be shared.

Moreover, since these electrode terminals 25, 26a to 26f are on the back side of the information display portion such as the picture frame 11b, the electrode terminals 25, 26a to 26f can be hidden from the viewer, and the external beauty can be improved. Can be held.

Further, since the ground side terminals of each of the color sheet ELs 12 to 17 are connected and shared, the number of lead wires 27 connected to these common ground terminals can be reduced to one. Can be further simplified.

FIG. 8 is an overhead view of an essential part of an information transmission device 31 according to a second embodiment of the present invention. The information transmission device 31 embeds the information display section of the color sheet light emitting display device 11 on a table 32 or a top plate 32a such as a desk so that figures and symbols such as a picture 11b of the surface 11a can be seen. On the other hand, an inverter 33 and a lighting control device 34, which are the EL driving devices, are arranged in a table 32.

The lighting control device 34 controls the lighting of each of the color sheet ELs 12 to 17 so that each part of the knitted picture 11b or a required color portion exhibiting a required color is lit, blinked, or turned off. It has become.

[0053] Therefore, by associating various information contents to be transmitted between the parties in advance with the lighting, turning off or blinking of each part of the knitted picture 11b, the lighting state of each part of the knitted picture 11b can be changed. It is possible to transmit predetermined information to a person who is watching the picture 11b on the table 32 without being known to a third party.

FIG. 9 is an overall configuration diagram of an information transmission system (device) 41 according to a third embodiment of the present invention. The information transmission system 41 is, for example, a plurality of tables 32 such as cabarets and bars, and is an information transmission system suitable for transmitting necessary information to customers only to hostesses or the like in secret. The remote control device 42 is electrically connected to each lighting control device 34 of the plurality of tables 32 to which the devices 31 are mounted by a signal line (not shown). It is characterized in that the lighting of each part or the required color part can be controlled remotely for each table 32 as appropriate.

In other words, the information to be transmitted is made to correspond in advance between the parties in regard to the point of each part or required color part of each combination picture 11b, the turning off or blinking. For example, when the centerpiece portion 11c or a predetermined color portion, for example, a red portion of the picture 11b lights or flashes, it is information indicating that "the host has received a call, answer the phone". When the hair part or the blue part of the picture 11b lights up or flashes, the store side and the hostess and other employees can communicate with each other, as in the information such as "A familiar customer has come to the store, so the hostess should move the table 32." In the meantime, the information is set in advance to a required portion of the knitting picture 11b, a light-off or blinking, so that the customer can be seated on the predetermined table 32 without being known to the customer. Information can be reliably transmitted to hostesses and other employees.

For this reason, even if the information to be transmitted is inconvenient for the customer, it can be securely transmitted to a predetermined hostess, an employee, or the like in a confidential manner.

Moreover, the knitting picture 11b has a three-dimensional depth and is aesthetically excellent as an art and craft, so that it can be used as a mere interior, and that it is a means of transmitting information. There is little risk of being realized. Note that a personal computer may be used as the remote control device 42.

[0058]

As described above, according to the first aspect of the present invention, a plurality of color sheet-shaped electroluminescent light-emitting devices (hereinafter, referred to as color sheet-like EL) having a required color and a required shape are stacked in the thickness direction. Therefore, the electrode terminals electrically connected to each pair of sheet electrodes can be formed at the same side end of each of the color sheet EL in a state where they are exposed to the outside.

Therefore, even if the number of stacked color sheet ELs increases, all of these electrode terminals are located at the same side end of the color sheet EL, so that lead wires can be easily connected to these electrode terminals. Connection can be quickly performed by soldering or the like, and a plurality of lead wires connected to these electrode terminals can all be drawn out in one direction on the same side, so that wiring can be routed easily. As a result, the risk of erroneous connection when connecting the lead wire to the EL driving device or the like can be reduced.
