Referring to fig. 1B again, fig. 1B is a schematic top view illustrating the first elastic waterproof membrane 110 and the first conductive pattern 120 thereon of the fabric module 100A of fig. 1A, wherein "schematic top view" means that the first elastic waterproof membrane 110 is seen from the second elastic waterproof membrane 112 of fig. 1A. As shown in fig. 1B, the first conductive pattern 120 is adhered to the surface of the first elastic waterproof film 110, and the first conductive pattern 120 has a plurality of first serial patterns 122 and a plurality of first conductive path patterns 123. The plurality of first serial patterns 122 extend along the first direction D1 and are electrically insulated from each other.

Referring to fig. 1C again, fig. 1C is a schematic top view of the second elastic waterproof membrane 112 and the second conductive pattern 124 of the fabric module 100A of fig. 1A, which is seen from the third elastic waterproof membrane 114 of fig. 1A to the second elastic waterproof membrane 112. As shown in fig. 1C, the second conductive pattern 124 is adhered to the surface of the second elastic waterproof film 112, wherein the second conductive pattern 124 is separated from the first conductive pattern 120 of fig. 1B by the second elastic waterproof film 112.

Referring to fig. 1D again, fig. 1D is a schematic top view of the fabric module 100A of fig. 1A, wherein the fabric module 100A of fig. 1D does not show the first fabric 102, the second fabric 104 and the third elastic waterproof membrane 114 of fig. 1A. As shown in fig. 1D, the control module 130 includes a controller 132, a flexible circuit board 134 and an anisotropic conductive adhesive 136, wherein the controller 132, the flexible circuit board 134 and the anisotropic conductive adhesive 136 are disposed on the first elastic waterproof film 110 and the second elastic waterproof film 112.

The controller 132 has a plurality of pins 133. The flexible circuit board 134 has conductive blind holes (not shown) and circuit patterns 135, wherein the pins 133 of the controller 132 are electrically connected to the circuit patterns 135 through the conductive blind holes, respectively. The line pattern 135 may be in contact with the first conductive pattern 120 on the first elastic waterproof film 110 and the second conductive pattern 124 on the second elastic waterproof film 112.

The anisotropic conductive adhesive 136 can have conductivity in a third direction D3, wherein the third direction D3 intersects a plane formed by the first direction D1 and the second direction D2. In more detail, the third direction D3 may be a direction out of (into) the paper surface, and is preferably a normal direction of the paper surface. The anisotropic conductive adhesive 136 disposed on the first elastic waterproof film 110 may be disposed between the first conductive pattern 120 and the circuit pattern 135 and may contact the first conductive pattern 120 and the circuit pattern 135, thereby enhancing the reliability of the electrical connection of the first conductive pattern 120 and the circuit pattern 135. Similarly, the anisotropic conductive adhesive 136 disposed on the second elastic waterproof film 112 may be disposed between the second conductive pattern 124 and the circuit pattern 135 and may contact the second conductive pattern 124 and the circuit pattern 135, thereby enhancing the reliability of electrical connection. Through the circuit pattern 135 of the flexible circuit board 134 and the anisotropic conductive adhesive 136, each pin 133 of the controller 132 is electrically connected to each serial pattern of the conductive patterns.

With the above configuration, the first serial pattern 122 of the first conductive pattern 120 and the second serial pattern 126 of the second conductive pattern 124 can be used as touch electrodes. For example, the first serial pattern 122 of the first conductive pattern 120 may be used as a transmitting electrode (Tx), the second serial pattern 126 of the second conductive pattern 124 may be used as a receiving electrode (Rx), and the controller 132 may use a capacitance coupled between the transmitting electrode (Tx) and the receiving electrode (Rx) as a touch detection source, so that the fabric module 100A has a touch function.

Please refer back to fig. 1A. The conductive pattern or the electrically-related element can be coated between the elastic waterproof films, so as to prevent the elastic waterproof films from being influenced by the outside, such as moisture or dust. Specifically, the first conductive pattern 120 of fig. 1B may be coated between the first elastic waterproof film 110 and the second elastic waterproof film 112, and the second conductive pattern 124 of fig. 1C may be coated between the second elastic waterproof film 112 and the third elastic waterproof film 114. In addition, the control module 130 of fig. 1D may also be disposed between the first elastic waterproof membrane 110 and the third elastic waterproof membrane 114, and the control unit 130 may include a wireless charging device and a wireless transceiver device, so that the control module 130 may also function in the elastic waterproof membrane. With the above configuration, since the conductive patterns and the electrically related elements of the fabric module 100A are all encapsulated between the elastic waterproof films, the fabric module 100A will not be affected by the placement of the fabric module 100A in water, i.e. the fabric module 100A has a water-washable property. In addition, adjacent elastic waterproof films may be adhered to each other, and the first elastic waterproof film 110 and the third elastic waterproof film 114 may be adhered to the first fabric 102 and the second fabric 104, respectively, so as to increase the sealing property of the elastic waterproof film to the inner space thereof, wherein the adhesion of the elastic waterproof film may be generated by performing a hot pressing process.

Referring again to fig. 1E, fig. 1E is a block flow diagram of a method of making fabric module 100A. As shown in fig. 1E, the method for manufacturing the fabric module 100A includes steps S10-S40.

Step S10 is to form a conductive pattern on the elastic waterproof film. In step S10, a first conductive pattern and a second conductive pattern are formed by disposing conductive ink on the first elastic waterproof film and the second elastic waterproof film, respectively, wherein the conductive ink is silver paste, for example. Then, the elastic waterproof film with the silver paste disposed on the surface thereof may be heat-baked to adhere the silver paste to the surface of the elastic waterproof film, thereby improving the reliability of the conductive pattern. Specifically, the temperature of the above-mentioned heat-baking is, for example, 100 ℃, and the heat-baking time is, for example, 10 minutes.

Step S20 is to set the control module on the elastic waterproof membrane. In step S20, the controller may be first bonded to the flexible circuit board. Then, a second elastic waterproof film is disposed on the first elastic waterproof film, and the second elastic waterproof film covers the first conductive pattern. The anisotropic conductive adhesive can be disposed on the first conductive pattern and the second conductive pattern, and the anisotropic conductive adhesive can be heated to 90 ℃ to increase the adhesion strength of the anisotropic conductive adhesive. In addition, the anisotropic conductive adhesive depicted in fig. 1D is in a strip shape, which may be, for example, an anisotropic conductive adhesive tape. However, in other embodiments, the anisotropic conductive adhesive may be dot-shaped, for example, liquid anisotropic conductive adhesive formed by dispensing. After the anisotropic conductive adhesive is configured, the controller and the flexible circuit board are arranged on the elastic waterproof film, wherein the circuit pattern of the flexible circuit board is aligned to the anisotropic conductive adhesive for connection. In addition, the process of connecting the circuit pattern of the flexible circuit board with the anisotropic conductive adhesive can be performed at normal temperature. After the flexible circuit board is arranged, the flexible circuit board can be further fixed on the elastic waterproof film through the anisotropic conductive adhesive in a hot pressing mode. Specifically, the temperature and pressure of the hot pressing process may be 140 ℃ and 2MPa, respectively.

Step S30 is to set an elastic waterproof film between the fabrics. In step S30, a third elastic waterproof film may be first covered on the first elastic waterproof film and the second elastic waterproof film, wherein the control module is also covered by the third elastic waterproof film. Then, the first elastic waterproof film, the second elastic waterproof film and the third elastic waterproof film are coated by the first woven cloth and the second woven cloth, and the control module is arranged between the first elastic waterproof film and the second elastic waterproof film.

Step S40 is to perform a hot pressing process. In step S40, the elastic waterproof films are adhered to each other by hot pressing, and the first elastic waterproof film and the third elastic waterproof film are adhered to the first fabric and the second fabric, respectively, wherein the temperature and the pressure of the hot pressing process are 140 ℃ and 2MPa, respectively. After the hot pressing of the elastic waterproof membrane is completed, the manufacturing process of the fabric module is completed.

On the other hand, when the conductive pattern is formed by the conductive ink, since the conductive ink is adhered to the surface of the elastic waterproof film, the conductive pattern is not broken when the elastic waterproof film is stretched, thereby continuously providing the touch function.

Specifically, a tensile test will be performed on the fabric module 100A to explain the change in elongation and capacitance of the fabric module of the present embodiment during stress.

Referring to fig. 1F and 1G, fig. 1F is a graph showing the relationship between the elongation and the tensile force of a fabric module in tensile test, wherein the horizontal axis and the vertical axis of fig. 1F are the elongation (in percent) and the tensile force (in kg), respectively; fig. 1G is a graph of elongation versus change in capacitance ratio for a tensile test on a fabric module, wherein the horizontal and vertical axes of fig. 1G are elongation (in: percent) and change in capacitance ratio (in: ratio), respectively.

As shown in fig. 1F, when the tensile force applied to the elastic waterproof film increases gradually to 5 kg, the elongation thereof increases gradually to about 80%, and no yield point (yield point) occurs, i.e., the elastic waterproof film does not undergo permanent deformation until the elongation thereof is about 80%. Then, as shown in fig. 1G, when the elongation of the elastic waterproof film is gradually increased to about 80%, the capacitance change gradually increases to about 1.12 times. Therefore, as can be seen from fig. 1F and 1G, when the elastic waterproof film having the conductive pattern disposed on the surface thereof is stretched within the elastic limit, the capacitance thereof does not change drastically. That is, the elastic waterproof film with the conductive pattern disposed on the surface can still exert the touch function within the elastic limit.

According to the above, the fabric module of the present embodiment includes two layers of fabric, a plurality of layers of elastic waterproof films, conductive patterns and a control module, wherein the fabric module can have a touch function through the conductive patterns and the control module. The conductive patterns and the control module are coated in the multilayer elastic waterproof film, so that the conductive patterns and the control module are prevented from being influenced by water vapor or dust fall. Since the conductive pattern and the control module are disposed within the multilayer elastomeric waterproof film, the fabric module is water-resistant. On the other hand, when the elastic waterproof film is stretched within the elastic limit, the capacitance of the elastic waterproof film does not change drastically, so that the elastic waterproof film with the conductive pattern arranged on the surface can still play the touch function within the elastic limit, that is, the fabric module has stretchability and does not influence the touch function during stretching.

Referring to fig. 2, fig. 2 is a schematic top view of a fabric module 100B according to a second embodiment of the disclosure, wherein the fabric module 100B of fig. 2 does not show the first fabric, the second fabric and the third elastic waterproof membrane. At least one difference between the present embodiment and the first embodiment is that: the control module 130 of the fabric module 100B of the present embodiment omits a flexible circuit board, that is, each pin 133 of the controller 132 of the control module 130 is directly fixed on the first conductive pattern 120 and the second conductive pattern 124 by the anisotropic conductive adhesive 136.

Further, the vertical projection of a portion of the pins 133 of the controller 132 on the first elastic waterproof film 110 overlaps with the first conductive pattern 120, and the vertical projection of another portion of the pins 133 of the controller 132 on the second elastic waterproof film 112 overlaps with the second conductive pattern 124, wherein the anisotropic conductive adhesive 136 is disposed on each of the pins 133 of the controller 132, so that the controller 132 can be electrically connected to the first conductive pattern 120 and the second conductive pattern 124 through the anisotropic conductive adhesive 136.

In addition, at least one difference between the manufacturing method of the fabric module 100B of the present embodiment and the manufacturing method of the fabric module 100A of the first embodiment is that: in the step of setting the control module on the elastic waterproof film, the present embodiment directly sets the controller on the elastic waterproof film and connects the pins of the controller with the anisotropic conductive adhesive.

Referring to fig. 3A again, fig. 3A is an exploded view of a fabric module 100C according to a third embodiment of the present disclosure.

In addition, the fabric module 100C may further include at least one set of conductive patterns and electronic components, so that the fabric module 100C may be functional, as will be described below.

Referring to fig. 3B, fig. 3B is a schematic top view of the first elastic waterproof membrane 110 of the fabric module of fig. 3A and the first conductive patterns 120 and the second conductive patterns 124 thereon, wherein "schematic top view" means that the first elastic waterproof membrane 110 is seen from the second elastic waterproof membrane 112 of fig. 3A. As shown in fig. 3B, the first conductive pattern 120 and the second conductive pattern 124 are adhered to the surface of the first elastic waterproof film 110, and the second conductive pattern 124 is adhered to a portion of the first conductive pattern 120, that is, the first conductive pattern 120 and the second conductive pattern 124 on the first elastic waterproof film 110 are partially overlapped.

The first conductive pattern 120 has a plurality of first serial patterns 122, wherein the plurality of first serial patterns 122 extend along a first direction D1. The first conductive pattern 120 may be divided into a first conductive region 121A and a second conductive region 121B, wherein the first conductive region 121A and the second conductive region 121B are separated from each other, such that the first serial pattern 122 in the first conductive region 121A and the first serial pattern 122 in the second conductive region 121B are electrically insulated from each other. In addition, the first serial patterns 122 in the first conductive regions 121A are electrically connected to each other, and the first serial patterns 122 in the second conductive regions 121B are electrically connected to each other. On the other hand, the first conductive pattern 120 may be silver paste.

The second conductive pattern 124 has a plurality of second serial patterns 126, wherein the plurality of second serial patterns 126 are electrically insulated from each other and extend along the second direction D2. The first direction D1 may intersect the second direction D2, e.g., the first direction D1 and the second direction D2 may be in an orthogonal relationship. In addition, each of the second serial patterns 126 may partially overlap the first conductive region 121A and the second conductive region 121B of the first conductive pattern 120, and the overlapping portion may have a rectangular shape. On the other hand, the second conductive pattern 124 may be an anisotropic conductive paste, and the anisotropic conductive paste has conductivity in a third direction D3, wherein the third direction D3 is a direction out of (into) the paper surface, and is preferably a normal direction of the paper surface.

Referring to fig. 3C again, fig. 3C is a schematic diagram illustrating an arrangement of the electronic components 140 of the fabric module 100C, wherein the fabric module 100C of fig. 3C does not show the first fabric 102, the second fabric 104 and the second elastic waterproof membrane 112.

With the above configuration, when the pins 133A and 133B of the controller 132 respectively output two different voltages (e.g., positive voltage and negative voltage), the first pin 142 and the second pin 144 of the electronic device 140 respectively have different potentials, so that the electronic device 140 generates bias voltage and emits light. That is, with the above configuration, the fabric module 100C may have a light emitting function.

Please refer back to fig. 3A. As in the first embodiment, the first conductive pattern 120, the second conductive pattern 124, the control module 130 and the electronic component 140 of fig. 3C can be wrapped between the first elastic waterproof film 110 and the second elastic waterproof film 112, so that the fabric module 100C has a water-washable property. Referring to fig. 3D again, fig. 3D is a block flow diagram of a method of making the fabric module 100C of fig. 3A. As shown in fig. 3D, the method for manufacturing the fabric module 100C includes steps S50-S90.

Step S50 is to form a conductive pattern on the elastic waterproof film. In step S50, a first conductive pattern and a second conductive pattern may be formed on the first elastic waterproof film, wherein the material of the first conductive pattern may be conductive ink, and the material of the second conductive pattern may be anisotropic conductive adhesive. Specifically, the silver adhesive is firstly arranged on the first elastic waterproof film, the first conductive pattern is formed after the first elastic waterproof film is heated and baked, and the heating and baking conditions can be set to be that the first conductive pattern is heated and baked for 10 minutes at the temperature of 100 ℃. And then, the anisotropic conductive adhesive is arranged on the first elastic waterproof film and part of the first conductive pattern, so that a second conductive pattern is formed. In addition, as described above, the anisotropic conductive adhesive may be anisotropic conductive adhesive tape or liquid anisotropic conductive adhesive.

Step S60 is to set the control module on the elastic waterproof membrane. In step S60, the controller may be first bonded to the flexible circuit board. Then, anisotropic conductive adhesive is disposed on the first conductive pattern and the second conductive pattern. After the anisotropic conductive adhesive is configured, the circuit pattern of the flexible circuit board is aligned to the anisotropic conductive adhesive for connection, and the flexible circuit board is further fixed on the elastic waterproof film through the anisotropic conductive adhesive in a hot pressing mode.

Step S70 is to dispose the electronic device on the elastic waterproof film. In step S70, the first pins and the second pins of the electronic device are aligned to the overlapping portions of the first conductive patterns and the second conductive patterns, so that the electronic device can be electrically connected to the first conductive patterns through the second conductive patterns. In addition, after the electronic component is configured, the first pins and the second pins of the electronic component can be further fixed on the second conductive patterns through a hot pressing mode.

Step S80 is to set an elastic waterproof film between the fabrics. In step S80, the second elastic waterproof film may be first covered on the first elastic waterproof film, wherein the control module is also covered by the second elastic waterproof film. Then, the first elastic waterproof film, the second elastic waterproof film and the control module arranged between the first elastic waterproof film and the second elastic waterproof film are wrapped between the first woven cloth and the second woven cloth.

Step S90 is to perform a hot pressing process. In step S90, similar to the first embodiment, the elastic waterproof films are adhered to each other by a hot pressing method, and the first elastic waterproof film and the third elastic waterproof film are adhered to the first fabric and the second fabric, respectively, so that the manufacturing process of the fabric module is completed after the hot pressing process is completed.

Referring to fig. 4 again, fig. 4 is a schematic top view illustrating a fabric module 100D according to a fourth embodiment of the disclosure, wherein the fabric module 100D of fig. 4 does not illustrate the first fabric, the second fabric and the second elastic waterproof membrane. At least one difference between the present embodiment and the third embodiment is that: the control module 130 of the fabric module 100D of the present embodiment omits the flexible circuit board, and the pins 133A and 133B of the controller 132 of the control module 130 are directly fixed on the first conductive area 121A and the second conductive area 121B of the first conductive pattern 120 by the anisotropic conductive adhesive 136, that is, the controller 132 can be directly connected to the first conductive pattern 120 by the anisotropic conductive adhesive 136.

Further, at least one difference between the manufacturing method of the fabric module 100D of the present embodiment and the manufacturing method of the fabric module 100C of the third embodiment is: in the step of setting the control module on the elastic waterproof film, the present embodiment directly sets the controller on the elastic waterproof film and connects the pins of the controller with the anisotropic conductive adhesive.

In summary, the fabric module of the present disclosure includes two layers of fabric, a plurality of layers of elastic waterproof film, conductive patterns and a control module, wherein the fabric module can be made to have functionality, such as a touch function or a light emitting function, through the conductive patterns and the control module. The conductive patterns and the control module are coated in the multilayer elastic waterproof film, so that the fabric module has washability. In addition, the fabric module may also be stretchable so that its functionality is not affected by stretching of the fabric.

While the present invention has been described with respect to various embodiments, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention, and it is intended that the scope of the invention be limited only by the terms of the appended claims.
