Description

TECHNICAL FIELD The present invention relates to a conductive transparent body for a display device.

[Prior Art] The present applicant has proposed a conductive transparent body for a display device described in JP-A-63-174216. This conductive transparent body,
A plurality of conductive wires are juxtaposed on a base body made of a transparent electrically insulating material so as not to short-circuit with each other.

In the case of using this conductive transparent body, a portion in which the power feeding portion provided on the peripheral side of the transparent body is connected to the power source side terminal of the conductive wire in the transparent body, and which is separated from the power feeding portion disposition portion of the transparent body. The display portion provided in the above is connected to the display side terminal of the conductive line in the transparent body for use.

According to the display device using the conductive transparent body, it is possible to produce an unexpected property such as lighting of the display element in the transparent space provided by the transparent body, and that the conductive line exists in the transparent space. Since it does not recognize, it is possible to provide a clean design.

[Problems to be Solved by the Invention] However, the prior art has the following problems.

When connecting the part which becomes the power supply side terminal of the conductive wire in the transparent body or the part which becomes the display side terminal to the power feeding part or the display part, the base part forming the transparent body is partially peeled off. Then, the conductive wire is partially exposed, and the exposed portion is used as a power supply side terminal or a display side terminal.
Then, the exposed surfaces of the terminals are subjected to electroless plating or electrolytic plating, and the terminals are soldered to the power supply section side conductor wire or the display section side conductor wire. That is, it is not easy because it is necessary to expose the conductive terminal each time the power supply unit is connected to the display unit and to solder the power supply unit side conductor wire or the display unit side conductor wire to the exposed conductive wire terminal.

A display element that constitutes the display unit is connected to a terminal of a conductive wire (display side terminal) fixed at an arbitrary position inside the transparent body, or a terminal of a conductive wire inside the transparent body of the control circuit of the display element (display side terminal) ), The work of finding the power supply side terminals is very difficult because the power supply parts are connected to the power supply side terminals of the conductive wires. This is because it is difficult to recognize the conductive wire in the transparent body, and it is difficult to continue tracing a certain conductive wire from the display side toward the power supply side.

When connecting the power supply unit to the display unit, it is difficult to select a sound conductive line that is not broken. This is because, in order to ensure the transparency of the transparent body, since the conductive wire is made of an ultrafine wire, the wire is likely to be broken during the manufacturing process, but it is difficult to detect the presence or absence of the wire.

The present invention simplifies the work of connecting the power supply unit to the display unit,
In addition, it is an object of the present invention to easily recognize the power supply side terminal of the conductive wire to which the display unit is connected and to easily select a sound conductive wire which is not broken.

When connecting the power supply unit to the conductive wire connected to the display unit, it is possible to use the power supply-side connector, which is implanted in the base portion in a state of being electrically connected to the conductive wire, as the power supply-side terminal of the conductive wire. it can. Therefore, it is not necessary to expose the conductive wire terminal each time when connecting the power supply section to the display section, and the connection of the power supply section to the power supply side connecting tool is not limited to soldering or the like, but a screwing structure, a socket, etc. The mating structure can be adopted and it is simple.

By applying a voltage to each of the power source side connecting tools and checking the energization state with the display section side, the power supply side terminal of the conductive wire to which the display section is connected can be easily recognized.

In the above, as a result of easily checking the energization state of each conductive wire connecting the display section and the power feeding section, a healthy conductive wire which is not broken can be easily selected.

According to the present invention described in claim 2, there are the following operational effects.

When connecting the display portion to the conductive wire, the display-side connector that is implanted in the base portion in a state of being electrically connected to the conductive wire in advance can be used as the display-side terminal of the conductive wire. Therefore,
It is not necessary to expose the conductive terminal each time the power supply section is connected to the display section, and the connection of the display section to the display-side connector is not limited to soldering, etc. The structure is simple and simple.
