[Embodiment] Next, an embodiment of the present invention will be described based on the drawings. In the drawing, 1 is a light emitting display device.

The light-emitting display section N1 is composed of a light-emitting display section 2 that forms a display screen using a plurality of light-emitting elements, and a display control section 3 that controls the light emission operation of the light-emitting elements. , as shown in Figure 8, a microcomputer (CP
It is a conventional device consisting of U, ROM, RAM), an IC card reader, a row driver (drive circuit), a column driver, etc.

On the other hand, the light-emitting display unit 2 has four circumferences formed by left and right ropes 4 that hang down due to fixed support at the upper end, and upper and lower shaft members 5 that are suspended horizontally between the left and right ropes 4, and can be hung on the outer wall of a building, etc. However, there are 4 left and right ropes and 5 upper and lower shaft members.
A plurality of horizontal electric wires 6 and vertical electric wires 7 each having an insulating coating are strung therebetween at a predetermined interval, thereby forming the light-emitting display section 2 into a net-like hanging curtain.

Reference numeral 8 denotes a light emitting unit attached to the intersection of the horizontal electric wire 6 and the vertical electric wire 7, and the light emitting unit 8 is formed of a resin material in the form of a combination of an upper case 9 and a lower case 1o. 9. On the mating surface of 10, orthogonal round holding grooves 9a, 9b with different groove depth dimensions are provided in order to avoid the intersection of both mold lines 6, 7 on the same plane and hold them.
10a and 10b are formed, respectively. In the light emitting unit 8, when the upper case 9 and the lower case 10 are integrated by appropriate means such as adhesive, the two mold lines 6.
At this time, the convex portion 10C formed on the lower case 10 side fits into the holding groove 9a on the upper case 9 side to guide the alignment of the upper and lower cases 9 and 10. It looks like this.

Furthermore, 11 and 12 are retaining grooves 9a and 9 of the upper case 9.
contact bins 11 and 12 are respectively provided to protrude into the interior of the contact bins 11 and 12, and these contact bins 11 and 12 are inserted into the horizontal electric wire 6 and the vertical electric wire 7, respectively, by penetrating the insulation coating and piercing the same.

A light emitting diode LED is connected in series between both contact pins 11 and 12 to prevent both mold wires 6 and 7 from coming out.
is connected to both type wires 6.7. That is, by attaching the light emitting unit 8, the light emitting diodes LEDs installed in the light emitting unit 8 are connected to each intersection of the horizontal electric wire 6 and the vertical electric wire 7, so that a so-called matrix array light emitting display section is formed. It has become. In addition, 9c
1 is a light emitting window formed in the upper case 9, and 13 is a weight attached to the lower end of the light emitting display section 3.

In the embodiment of the present invention configured as described above, the light-emitting display section 2 can be manufactured by an extremely easy operation of simply attaching the light-emitting unit 8 to the intersection of the electric wires 6 and 7 crossed in the vertical and horizontal directions. The light-emitting display is activated by connecting the horizontal wires 6 to the row drivers of the display control unit 3 and the vertical wires 7 to the column drivers, but since this is an extremely lightweight suspension structure, no installation work is required. It can be installed on the outer wall of a building without any need for storage, and when it is not needed, it can be removed and rolled up around the shaft material 5 for compact storage.

As described above, in the present invention, the light emitting display is performed on a large screen, but since it is formed into a net-like hanging curtain shape by the electric wires 6 and 7 crossed vertically and horizontally, the number of parts can be reduced. Not only can this be greatly reduced, but the manufacturing process can also be significantly simplified, and as a result, the cost of light-emitting display devices can be dramatically reduced. Moreover, since it does not require any special installation work and can be removed, it is easy to secure a space for installation, and the luminous display is performed only during the necessary period, something that conventional large luminescent display devices cannot do. It can be used for applications that could not be achieved before, and since it can be removed for maintenance, maintainability can be significantly improved compared to conventional light emitting display devices that are integrated into buildings. Furthermore, since the light emitting display section is formed in a net shape, it is extremely convenient because it is not easily affected by wind.

Furthermore, in the embodiment, the light emitting unit 8 is formed into a unit, and the light emitting unit 8 is connected to a fixing member that fixes the intersection of the vertical and horizontal electric wires 6 and 7, and one light emitting diode LED is connected to both electric wires 6.7. Since it is also used as a connecting member for the purpose, the structure can be further simplified, the manufacturing process can be simplified, and the price of the product can be reduced.

It should be noted that the present invention is of course not limited to the above-mentioned embodiments, and the light-emitting display section does not necessarily have to be formed on a vertical hanging banner as in the above-mentioned embodiments, but may be formed, for example, on a horizontal banner. Furthermore, it is also possible to use it as an advertising screen for atto balloons.

[Operations and Effects] In summary, the present invention is configured as described above, and by activating a plurality of light emitting elements arranged on a display screen to emit light, news messages, advertising messages, etc. consisting of characters, symbols, figures, etc. can be sent. However,
Since the light-emitting display screen is formed in a net shape with light-emitting elements arranged at intersections, it can be used as a hanging curtain installed on the outer wall of a building. Therefore, no special installation work is required during installation, and removal is possible.
Perhaps because it is easier to secure an installation location, it can now be used for applications that are not possible with conventional large luminescent display devices, such as displaying luminescence only for a necessary period of time. performance can also be significantly improved. Moreover, since it has an extremely simple configuration in which light emitting elements are placed at the intersections of the mesh formed by electric wires, the number of parts can be significantly reduced.
The manufacturing process can also be significantly simplified, and the cost of the light emitting display device can be dramatically reduced.

Furthermore, if the light emitting unit is configured as a light emitting unit equipped with contact pins that connect the light emitting element to the vertical and horizontal electric wires by piercing the vertical and horizontal electric wires, the light emitting unit can be used to fix the intersections of the vertical and horizontal electric wires. Since it can be used both as a fixing member and a connecting member for connecting the light emitting element to both electric wires, the structure can be further simplified.
Furthermore, the cost of the light emitting display device can be reduced.
