Description

[Detailed description of the invention]

[! Field of Application of Soil Collection] The present invention relates to a large-sized display device, such as one used by hanging from the side of a building, and in particular relates to a connection method during construction thereof.

[Conventional technology]

Conventionally, the method for constructing this type of large display device is as follows:
As shown in FIG. 3, for example, a square module 31 with sides of 1 m is formed, and electrical connections are made on the back side of the module 31 using a connector 33 with wires, etc., as shown in FIG. It was something to do.

[Problem to be solved by the invention]

However, since the conventional method described above requires two types of connections, mechanical and electrical, there is a problem in that the workability is generally poor, especially for this type of large display device. In this case, the driving for display is very complicated, as dynamic driving such as matrix is performed within the module 31, and dynamic driving is performed for each module 31, and accordingly, the electrical connections described above are also complicated. As a result, problems such as connection errors often occur, and solutions to these problems have been a challenge.

[Means to solve the problem]

The present invention provides a module connection method for constructing a large display device by mechanically and electrically connecting individual modules. The electrical wiring placed at the end of the connecting side facing each other is set so that the pairs to be connected are facing each other, and the electrical wiring is placed at the position of the electrical wiring on the connecting side. A module connection of a large display device, characterized in that a conductive fastener claw is attached to the other part, an insulating fastener claw is attached to the other part to form a slide fastener, and the slide fastener is attached. By providing a method, the above-described mechanical connection and electrical connection can be performed simultaneously and without causing erroneous connections, thereby solving the above-described conventional problems.

【Example】

Next, the present invention will be explained in detail based on an embodiment shown in the drawings. In FIG. 1, reference numeral 1 indicates a large display device, which is a part of the large display device, and this large display device 1 includes, for example, 24×24 dot LED lamps 2b arranged on a sheet-like base material 2a, and further on the same substrate 2a. It is a conventional example that a plurality of modules 2 are connected vertically and horizontally, each of which is equipped with a driving circuit (not shown) for driving the LED lamp 2b and has appropriate wiring. However, according to the present invention, the connection method when connecting the modules 2 is based on the fastener 3 configured to be able to perform mechanical connection and electrical connection at the same time. FIG. 2 shows the connection method of the present invention in more detail. The positions of the electrical wiring 2C provided at the respective ends of the left connecting side 2L of the module 2s and the right connecting side 2R of the other module 2T are determined by, for example, power line to power line, ground line to ground line, clock line, etc. Pairs to be connected, such as a clock or a signal output and a signal input, are placed facing each other. . Note that when the base material 2a is formed of a resin film, this laying may be done by a known method such as etching used in the manufacturing method of printed circuit boards, and when the base material 2a is a cloth base material, a known method such as etching may be used. Any method may be used, such as direct adhesion of copper foil or adhesion to a predetermined position of a flexible printed circuit board. Fastener claws are attached to the four sides of the module 2 formed as described above or to the connection side connected to another module 2, thereby forming one side of the slide fastener 3. Here, the fastener claws are Two types of fastener claws 3a are prepared: conductive fastener claws 3a made of a conductive material such as metal, and insulating fastener claws 3b made of an insulating material such as resin. The conductive fastener claws 3a are engaged so as to be connected to the electrical wiring 2c, and the insulating fastener claws 3b are engaged at other positions, ie, at positions where the electrical wiring 2c is not provided. It goes without saying that the conductive fastener claws 3a and the insulating fastener claws 3b have the same shape in their main parts except for their constituent members. There is no difference in the joint performance of the slide fastener 3 even when they are combined in a complicated manner. An appropriate number of modules 2 configured in this manner are connected vertically and horizontally to obtain the desired large-sized display device 1. Next, to explain the operation and effect of the present invention explained above, first, the electrical wiring 2c installed on the opposing sides where the modules 2 are connected to each other is arranged so that the pairs to be connected face each other. Furthermore, a conductive fastener claw 3a to be connected to the electrical wiring 2c is attached to the position where the electrical wiring 2c is laid, and an insulating fastener claw 3b is engaged to the other position to fasten the slide fastener. 3, and by using the connection method of splicing the slide fasteners 3, the pair of electrical wirings 2C to be connected can be connected to the conductive wires at the time when the modules 2 are mechanically connected by the slide fasteners 3. Electrical connection is also made at the same time by the conductive fastener claws 3a, and since electrical conductivity does not occur across the entire slide fastener 3 due to the insulating fastener claws 3b separated from other parts, the above-mentioned connection is possible. Independent connection of each pair of electric wiring lines 2C is ensured.

【Effect of the invention】

As explained above, according to the present invention, the laying positions of the electrical wiring arranged at the ends of the opposing connection sides of adjacent modules are set so that the pairs to be connected face each other, and A conductive fastener claw connected to the electrical wiring is engaged at the position of the electrical wiring, an insulating fastener claw is engaged at other parts to form a slide fastener, and the slide fastener is attached. By using this method of connecting modules for large display devices, when the modules are mechanically connected, the electrical connection can also be made simultaneously and easily using the conductive fastener claws. It has the outstanding effect of simplifying the extremely time-consuming connections and increasing work efficiency by making electrical connections separately, and it also eliminates errors by automatically making complex electrical connections without checking the connection positions. It also has the excellent effect of preventing accidents that occur during connection, such as failure of electrical circuits due to connection or incorrect connection.
