Description

  The present invention relates to an input device, and more particularly to an input device provided with a conductor portion that blocks an influence of a finger to be operated or shields noise from the outside.

  A display unit of an electronic device such as a smartphone or a tablet terminal uses a translucent electrostatic input device for performing coordinate input by directly operating a menu item or object of a display image with a finger or the like. . Patent Document 1 discloses a capacitance type input device that is hardly affected by electromagnetic noise entering from outside.

  FIG. 13 is a partially enlarged cross-sectional view of a conventional capacitance type input device described in Patent Document 1. As shown in FIG. 13, a conventional input device 110 includes a translucent base material 121, a plurality of first electrodes 122 and a plurality of second electrodes formed on one surface 121a of the base material 121. (In FIG. 13, only the connection portion 128 for connecting a plurality of second electrodes is shown). A wiring 129 connected to the first electrode 122 and the second electrode is formed in the non-input region 116.

  In the input device 110 of the conventional example, the first electrode 122 and the second electrode are electrically insulated and disposed in the input region 115, and static electricity is provided between the first electrode 122 and the second electrode. Form a capacitance. When a detection object such as an operator's finger contacts or approaches the input region 115 of the input device 110, the capacitance between the first electrode 122 and the second electrode changes, and based on this Input position information can be detected.

  Since the detected input position information is drawn out to an external circuit through the wiring 129, when electromagnetic noise enters from the outside and is superimposed on the wiring 129, it is confused with the input position information and erroneous detection occurs. As shown in FIG. 13, a conductor portion 155 is formed through an insulating layer 154 at a position overlapping the wiring 129. Thereby, the electromagnetic wave noise which invades from the outside of the input operation side can be shielded. Therefore, it is possible to prevent erroneous detection and detect input position information with high accuracy.

  However, since the thickness of the insulating layer 154 is about 1 μm to 2 μm and the distance between the wiring 129 and the conductor portion 155 is small, the capacitance formed between the wiring 129 and the conductor portion 155 is large. Become. For this reason, the capacitance change between the first electrode 122 and the second electrode in the input region 115 becomes relatively small, which causes a problem that the detection sensitivity is lowered.

  In order to deal with this problem, it has been studied to provide the conductor portion 155 on the other surface 121b of the base 121. Since the thickness of the base material 121 is about 50 μm to 100 μm, the distance between the conductor portion 155 and the wiring 129 increases, and the capacitance formed between the wiring 129 and the conductor portion 155 increases. It is suppressed. Therefore, a decrease in detection sensitivity in the input area 115 can be prevented.

Further, in the case where the conductor portion 155 is provided on the other surface 121b, it is necessary to apply a predetermined voltage to the conductor portion 155. Therefore, a step of providing a terminal portion also on the other surface 121b to connect a flexible substrate or the like. Cost.

  Therefore, after performing the connection process on one surface 121a, it is necessary to turn over the base material 121 and perform the connection process on the other surface 121b, which is complicated and leads to an increase in manufacturing cost. Furthermore, since a resin material in the form of a film is used for the base material 121, if connection by thermocompression bonding is performed a plurality of times, there is a possibility that the input operation cannot be detected due to damage. In addition, it is necessary to prepare a plurality of external flexible boards to connect to the terminal portions of the one surface 121a and the other surface 121b, or to have a special configuration in which connection terminals are formed on both surfaces.

As shown in FIG. 4, an insulating layer 35 (not shown in FIG. 2) is provided to cover the connection portion 34. And the bridge | bridging part 33 is provided ranging over the connection part 34 and the insulating layer 35, and connects the 1st electrode 31 to a X1-X2 direction. In this way, the first electrode 31 and the second electrode 32 are arranged to be insulated from each other, and a capacitance is formed between the first electrode 31 and the second electrode 32. When the operator performs an input operation, when the object to be detected is brought close to the front panel 41, a capacitance is formed between the object to be detected and each of the electrodes 31 and 32, and the first electrode 31 and the second electrode It is added to the capacitance between the electrodes 32. Input position information can be detected based on this capacitance change.

  As shown in FIG. 2, in the input device 10 according to the present embodiment, a first lead portion 22 and a second lead portion 23 extending from the base material 21 are formed. The first lead portion 22 is provided with a terminal portion 24, and a plurality of terminals are arranged in parallel. In addition, as shown in FIG. 2, electrode part wirings 36 are connected to the connected first electrode 31 and the connected second electrode 32, respectively. The electrode part wiring 36 is formed around the non-input area 16 of the base material 21 to form the first lead part 22 and is connected to the terminal part 24. An external substrate (not shown) or the like is connected to the terminal unit 24, and input position information is output to an external circuit (not shown) such as an IC.

In this embodiment, the base material 21 is formed using a film-like resin material, and includes polycarbonate resin (PC), polyethylene terephthalate resin (PET), polyethylene naphthalate resin (PEN), cyclic polyolefin (COP), A translucent resin material such as polymethyl methacrylate resin (PMMA) is used.

  FIG. 3 is a plan view showing the base material constituting the input device of the present embodiment as viewed from the second surface side. As shown in FIG. 3, a conductor portion 55 is provided on the second surface 18 of the base material 21. The conductor portion 55 is provided in the non-input area 16 and is formed in a frame shape surrounding the input area 15. As shown in FIG. 3, a second relay terminal portion 26 is provided on the second surface 18 of the second lead portion 23. The conductor portion 55 is electrically connected to the second relay terminal portion 26 via a conductor portion wiring 56.

  The conductor portion 55 is formed by a thin film method such as sputtering or vapor deposition using, for example, a metal material such as Cu, Ag, or Au, an alloy such as CuNi or AgPd, or a conductive oxide material such as ITO. Moreover, it can form by printing methods, such as screen printing and inkjet printing, using the ink containing said material. The conductor portion 55 can be formed at low cost by printing.

  As shown in FIG. 4, the second surface 18 of the base material 21 is bonded to the front panel 41 via the adhesive layer 42. The conductor portion 55 is formed closer to the surface panel 41 than the electrode portion wiring 36 at a position overlapping the electrode portion wiring 36. As a result, when a detected object such as a finger is brought close to the input region 15 during an input operation, a voltage is applied to the conductor portion 55 to control it to the same potential as the electrode portion wiring 36, whereby the finger and the electrode portion wiring 36 are controlled. It is possible to prevent a capacitance from being formed between the two. Since the electrostatic capacitance is eliminated between the finger and the electrode part wiring 36, the detection sensitivity of the first electrode 31 and the second electrode 32 can be improved.

  Further, as shown in FIG. 4, the base material 21 is interposed between the conductor portion 55 and the electrode portion wiring 36. As the base material 21, a film material having a thickness of about 50 μm to 200 μm is used. Therefore, since the distance between the conductor part 55 and the electrode part wiring 36 can be made sufficiently large, an increase in the capacitance formed between the conductor part 55 and the electrode part wiring 36 is suppressed, and the input region 15 is prevented from lowering the detection sensitivity.

  As shown in FIG. 4, the decorative layer 43 is laminated so as to cover the conductor portion 55, and the decorative layer 43 is formed in a frame shape so as to substantially coincide with the non-input region 16 in plan view. (In FIG. 1, FIG. 3, the decoration layer 43 is abbreviate | omitted and shown). Thereby, it can prevent that the conductor part 55 is visually recognized by the operator. The decorative layer 43 can be formed by a printing method using colored ink. The decorative layer 43 may be printed on the non-input area 16 of the front panel 41.

  FIG. 5 is a partially enlarged plan view of the first lead portion and the second lead portion, and shows a state in which the first lead portion and the second lead portion are not connected.

The relay terminal portion 25 is electrically connected through wiring.

  As shown in FIG. 5, a second relay terminal portion 26 is formed on the second protrusion 23a on the second surface 18 of the second lead portion 23, and the second relay terminal portion 26 is a conductor. It is connected to a conductor portion 55 (not shown in FIG. 5) via a partial wiring 56.

  The second protruding portion 23a is provided on the outer peripheral side (Y1 side) of the base material 21 relative to the first protruding portion 22a, that is, the distance between the second relay terminal portion 26 and the base material 21 is It can be said that the distance between the first relay terminal portion 25 and the base material 21 is larger. In the X1-X2 direction, the first protrusion 22a and the second protrusion 23a are formed at overlapping positions.

  By forming the first lead portion 22 and the second lead portion 23 as described above, the second lead portion 23 is bent and deformed as shown in FIGS. 6 (a) and 6 (b). By doing so, the 2nd protrusion part 23a can be moved to the Y2 direction, and the 1st protrusion part 22a and the 2nd protrusion part 23a can be made to oppose. Thereby, the 1st relay terminal part 25 and the 2nd relay terminal part 26 can be made to oppose and can be connected easily.

  Further, in the input device 10 of the present embodiment, the first drawer portion 22 and the second drawer portion 23 are formed integrally and continuously with the base material 21. Thereby, since the 2nd drawer | drawing-out part 23 is formed with the same film-like material as the base material 21, it can be changed easily and the 2nd relay terminal part 26 is connected to the 1st relay terminal part 25. .

  Note that, as shown in FIG. 6B, the first relay terminal portion 25 and the second relay terminal portion 26 are connected to face each other via a conductive adhesive 57. In other words, the second surface 18 of the first lead portion 22 is connected so that the first surface 17 of the second lead portion 23 faces the second surface 18 of the first lead portion 22. An anisotropic conductive adhesive can be used as the conductive adhesive 57, for example, an anisotropic conductive film (ACF, Anisotropic Conductive Film) or an anisotropic conductive paste (ACP, Anisotropic Conductive Paste) can be used. Thereby, the 1st relay terminal part 25 and the 2nd relay terminal part 26 are a simple structure, and are connected reliably.

  In this way, the second relay terminal portion 26 is electrically connected to the terminal portion 24 via the first relay terminal portion 25. Accordingly, the electrodes 31 and 32 are electrically connected to the terminal portion 24 provided on the first surface 17 of the first lead portion 22, and the conductor portion 55 is also connected to the first relay terminal portion 25 and It is electrically connected to the terminal part 24 through the second relay terminal part 26. Therefore, when connecting the terminal portion 24 and the external substrate or the like, it is possible to connect from the same surface side, so that the connection process can be simplified and the manufacturing cost can be reduced. Moreover, since it is not necessary to connect on both surfaces of one base material 21, it is not necessary to prepare an external substrate or a plurality of external substrates that can be connected on both surfaces of the base material 21, leading to a reduction in manufacturing cost. .

  In addition, since the first lead portion 22 and the second lead portion 23 are formed and connected at a position away from the input region 15, even when a connection process such as thermocompression bonding is performed, the input region The trouble which arises by a connection process, such as generation | occurrence | production of the distortion | strain of 15 base materials 21, can be suppressed.

  Therefore, according to the input device 10 of the present invention, it is possible to simplify the connection process with an external substrate or the like and reduce the manufacturing cost.

  In the present embodiment, as shown in FIG. 5, the first relay terminal portion 25 is provided in the first protrusion 22a, and the second relay terminal portion 26 is provided in the second protrusion 23a. Yes. By providing the first projecting portion 22a and the second projecting portion 23a in this way, the first relay terminal portion 25 and the second projecting portion 25 are not affected by the routing structure of the electrode portion wiring 36, the conductor portion wiring 56, and the like. The relay terminal part 26 can be provided, and a design freedom increases.

  Moreover, since the 1st drawer | drawing-out part 22 and the 2nd drawer | drawing-out part 23 are the film-form materials formed by extending elongate, when a big stress is added, there exists a possibility that a damage and a disconnection may arise. In this embodiment, the 1st protrusion part 22a and the 2nd protrusion part 23a are provided, and the 1st relay terminal part 25 and the 2nd relay terminal part 26 are provided in the position which overlaps in a X1-X2 direction. For this reason, as shown in FIGS. 6A and 6B, when connecting, the second lead-out portion 23 is deformed and connected so that the second projecting portion 23a is moved in the Y2 direction. Is possible. Therefore, when connecting, a force is applied to the second lead portion 23 in the direction parallel to the extending direction (Y2 direction), and the stress in the X1-X2 direction is suppressed from being applied. Damage to the drawer 23 is prevented. In addition, even after the connection, the stress in the X1-X2 direction remains in the first lead portion 22 and the second lead portion 23 is reduced.

  In the present embodiment, as shown in FIG. 5, the second protrusion 23 a is provided on the outer peripheral side (Y1 side) of the base material 21 relative to the first protrusion 22 a. However, the present invention is not limited to this, and the first protruding portion 22a can be provided on the outer peripheral side (Y1 side) of the base material 21 with respect to the second protruding portion 23a. In this case, the first protruding portion 22a is moved in the Y2 direction by bending and deforming the first lead portion 22, and the first protruding portion 22a and the second protruding portion 23a are opposed to each other. Can do. Thereby, the 1st relay terminal part 25 and the 2nd relay terminal part 26 can be faced and connected. However, the first lead portion 22 has more wires than the second lead portion 23, and there is a risk of disconnection. Moreover, the width | variety is thick compared with the 2nd drawer | drawing-out part 23, and the operation | work which bends and deform | transforms is complicated. Therefore, it is more advantageous to bend and deform the second lead portion 23 than to bend and deform the first lead portion 22.

  FIG. 7 shows a first modified example of the input device according to the present embodiment, and is a partially enlarged plan view of the first lead portion and the second lead portion. FIG. 7 is a plan view showing a state in which the first lead portion 22 and the second lead portion 23 are not connected.

Is provided.

  When the notch 28 is not provided, the first lead portion 22 and the second lead portion 23 are separated from the base material 21 when the first relay terminal portion 25 and the second relay terminal portion 26 are connected. Stress tends to concentrate in the vicinity of the extending portion, and particularly stress concentrates on corners formed by the first and second lead portions 22 and 23 and the outer periphery of the base material 21. This may cause disconnection of each wiring 36 and damage to the respective lead portions 22 and 23. As shown in FIG. 7, by providing the notch 28, stress concentration can be suppressed and damage to the first lead portion 22 and the second lead portion 23 can be prevented.

  In the present modification, the notch 28 is formed in a semicircular shape with a curve, and stress concentration can be effectively prevented. The shape of the notch 28 is not limited to this, and may be other shapes such as a polygonal shape capable of dispersing stress.

Therefore, the conductor portion 55 is electrically connected to the terminal portion 24 via the first relay terminal portion 25 and the second relay terminal portion 26. Further, when the terminal portion 24 and the external substrate are connected via the conductive adhesive 57, the step of providing the conductive adhesive 57 on both the terminal portion 24 and the first relay terminal portion 25 is performed once.
