description
Field The present invention relates to a touch panel and a portable device.
Background In recent years, in a display device such as a liquid crystal display element provided in a mobile device, a mobile phone device, a car navigation device, or the like, a touch panel (also referred to as a touch-sensitive screen) for detecting an operation input is often available. As a type of the touch panel, a capacitive touch panel is known (for example, PTL 1). The touch panel described in PTL 1 has electrodes in the X-axis direction and Y-axis direction provided on a glass substrate and has signal lines (wiring) connected to the respective electrodes. The signal lines from the respective electrodes are brought together at a predetermined position on the glass base material, and a connection portion in which the signal lines are collected is connected to FPC (flexible printed circuits) by thermocompression bonding or the like. An actuating signal to the touch panel or an output signal from the touch panel is transmitted via the FPC to or from a substrate on which a control IC (integrated circuit) or the like is applied.

Summary However, in the touch panel described in PTL 1, it is necessary to secure a region for thermocompression bonding between the connection part and the FPC, and this has a problem that the downsize of the touch panel is difficult is. In addition, by narrowing the signal line that extends around an outer periphery of a base material, a resistance value per unit length of the signal line is increased and an impedance of the signal line is increased, and hence there is a possibility that the S / N ratio of the signal that is transmitted through the signal line, is reduced and the detection performance of the touch panel deteriorates. Particularly when the touch panel is a product with a narrow frame, it is necessary to make the signal line thinner, and thus there is a possibility that the above-mentioned problem is significant.
Furthermore, in recent years it has also been necessary to deal with the advancement of the narrowing of the frame of the display device in the touch panel. In particular, it is necessary to bend an output portion from the base material immediately outside the display device and to turn it over to the substrate side. In such a case, it is difficult to secure the region for thermocompression bonding. Furthermore, if the base material itself is bent without using the FPC, there is a problem that the signal line on the base material is broken. In addition, if the signal line is broken or a connection error occurs when connecting by thermocompression bonding or the like, the product must be discarded and the yield may be reduced.
[0006] Therefore, an object of an aspect of the present invention is to provide a new and useful touch panel and a portable device which solve the above-mentioned problems.
[0007] One aspect of the present invention is a touch panel including: a sensor having a base material, a plurality of first electrodes provided on the base material and configured to detect electrostatic capacity, and a plurality of connection pads connected to the plurality from the first electrodes and provided along a first outer peripheral portion of the base material all along the first outer peripheral portion; a substrate on which a plurality of second electrodes are provided along a second outer peripheral portion all along the second outer peripheral portion; and an anisotropic conductor interposed between the first outer peripheral portion of the sensor and the second outer peripheral portion of the substrate anywhere between the first and second outer peripheral portions and in contact with the plurality of the first electrodes and the plurality of the second electrodes ,
According to one aspect of the present invention, at least the region for thermocompression bonding between the connection portion and the FPC can be made unnecessary. It should be noted that content from one aspect of the present invention is not construed to be limited by the effects exemplified in the present description.

<1. First embodiment>
Hereinafter, a first embodiment of an aspect of the present invention will be described. In one aspect of the present embodiment, as an example of a touch panel, a self-capacitance type capacitive touch panel for detecting a change in electrostatic capacity between an electrode and a human body (fingertip), a stylus for operation, or the like is described as an example. Such a touch panel can be used as an input device by various electronic devices such as a cellular phone and a car navigation device. In the present embodiment, an example is described in which the touch panel is attached to a wristwatch type portable device.
[Example of overall configuration of portable device] Fig. 1 is an exploded view of a portable device 1 according to a first embodiment. The portable device 1 includes, for example, a sensor 2, a substrate 3, a zebra connector 4, which is an example of an anisotropic conductor, and a display device 5. The sensor 2, the display device 5, the zebra connector 4 and the substrate 3 are in a direction AA, which is by a user of the portable
CH 714 334 A2
Device 1 is detected visually, arranged one above the other. The touch panel (a touch panel 10) according to an aspect of the present embodiment has a structure that includes the sensor 2, the substrate 3, and the zebra connector 4 in a structure of the above-described portable device 1.
[0016] Subsequently, each part from which the portable device 1 is composed will be described in detail. First, the sensor 2 will be described in detail. 2 is a plan view for explaining a structural example of the sensor 2, and is a view showing electrodes 22 and the like which will be described later as viewed from an operator input surface side. The sensor 2 has a circular base material 21. The base material 21 is an insulating material such as glass or film and is a transparent material to such an extent that a display device content of the display device 5 can be visually recognized. An electrode 22 (a first electrode) is provided on a main surface of the base material 21 facing the substrate 3. In an example shown in FIG. 2, sixteen electrodes 22 are provided and these electrodes 22 are insulated from one another.
On an outer peripheral portion (a first outer peripheral portion) of the base material 21, a connection pad 23 connected to the electrode 22 is provided along the outer peripheral portion thereof. The outer peripheral portion of the base material 21 means a region near an outer edge of the base material 21. The connection pad 23 is a portion to which an electrode described later is electrically connected from the substrate 3 via the zebra connector 4. Specifically, two connection pads 23a and 23b provided on the outer peripheral portion of the base material 21 are connected to a specific electrode 22a. Furthermore, a connection pad is connected to each of four electrodes 22 arranged near a center of the base material 21. As described above, the number of connection pads 23 connected to an electrode 22 may be one or more, but it is preferable to use a plurality of connection pads 23 in order to enlarge a contact area of the connection pad 23 so that contact resistance is reduced can.
The electrode 22 and the connection pad 23 are transparent electrode patterns made of an ITO (indium tin oxide) film or the like. The electrode 22 and the connection pad 23 are formed by a method using, for example, a photolithography method or a laser etching method. The shape and the number of the electrodes 22, the shape and the number of the connection pads 23 are appropriately determined according to the structure formation at the time of the formation of the electrodes 22 and the connection pads 23, a size of the base material 21 and the like. In addition, the electrode 22 and the connection pad 23 may be formed by a printing method using a transparent conductive ink, or a method of forming the electrode 22 and a method of forming the connection pad 23 may be different from each other.
[Substrate] Next, the substrate 3 will be described in detail. 3 is a view for explaining a structural example of the substrate 3. The substrate 3 is substantially the same size as the size of the sensor 2 and has a circular shape. The substrate 3 has electrodes (second electrodes) 31 provided along an outer peripheral portion (a second outer peripheral portion) of the substrate 3. The electrode 31 is electrically connected to the connection pad 23 described above from the sensor 2 via the zebra connector 4. 3, although the electrodes 31 are provided at substantially equal intervals along the outer peripheral portion, it is not necessary that all of the electrodes 31 are electrically connected to the connection pads 23, and only some of the electrodes 31 may be are electrically connected to the connection pads 23. Furthermore, a number of electrodes 31 can be provided at suitable positions on the substrate 3 in accordance with an arrangement pattern of the connection pads 23.
A control IC (not shown) as a control unit is mounted on the substrate 3. The control IC is connected to the electrode 31 and is connected to the sensor 2 via the electrode 31 and the zebra connector 4. The control IC sends a control signal to the sensor 2 and detects a position where a touch operation is performed on the sensor 2 based on an output signal from the sensor 2. The control IC performs various control operations according to a detection result.
[Zebra connector] Next, the zebra connector 4 will be described in detail. 4 is a perspective view for explaining a structural example of the zebra connector 4, and FIG. 5 is a cross-sectional view showing a cross section when the zebra connector 4 is cut along a section line A-A in FIG. 4. The zebra connector 4 is inserted between an outer peripheral portion of the sensor 2 and an outer peripheral portion of the substrate 3. The zebra connector 4 is a rubber-like material with a certain elasticity and has essentially the same size ( Diameter) such as the base material 21 and the substrate 3 from the sensor 2. The zebra connector 4 has an annular base portion 41. A step-shaped portion 42 is formed substantially in the center of a main surface (a surface close to the operator input side) of the base portion 41. An inside of the base portion 41 is lower than one
CH 714 334 A2
Outside through the step-shaped portion 42, and a cross section of the base portion 41 has an L-shape as shown in FIG. 5. The base portion 41 has an outer peripheral upper surface 43a and an inner peripheral upper surface 43b than the one main surface and a lower surface 44 as the other main surface.
In the base portion 41 of the zebra connector 4, a conductive portion 45, which is a conductive portion, and an insulating portion 46, which is an insulating portion, are alternately formed, and the conductive portion 45 selectively conducts between the outer peripheral top surface 43a or the inner peripheral top surface 43b and bottom surface 44. In Fig. 4, the conductive portions 45 are hatched. In FIG. 4, for a simple understanding, a distance interval between the conductive part 45 and the insulating part 46 is shown, which is large, but in the case of the zebra connecting piece 4, in which the conductive part 45 and the insulating part 46 are formed, the distance intervals are smaller, for example a distance of about 0.1 to 0.3 mm can also be used in a suitable manner.
[Display device] Next, the display device 5 will be described in detail. The display device 5 is inserted between the sensor 2 and the substrate 3. The display device 5 consists of an LCD (liquid crystal display device), an OLED (organic light-emitting diode) or the like and can display as desired using a dot matrix. The display device 5 has a circular shape and is large in size so that an outer peripheral portion (a region near an outer edge) of the display device 5 can be placed on the inner peripheral upper surface 43b of the zebra connector 4. Contents corresponding to functions from the portable device 1 are displayed on the display device 5. For example, the date, time, environmental information such as temperature, humidity and atmospheric pressure, current position or the like are displayed on the display device 5. A game display device, television, information obtained from a network such as the Internet, or the like can be displayed on the display device 5. In addition, information obtained by connecting the portable device 1 to a portable device such as a smartphone or the like can be displayed on the display device 5.
Consider that a circuit for operating the display device 5 can also be applied to the substrate 3. The circuit for operating the display device 5 is a circuit with a control IC or the like as a control unit for performing control according to a structure of the display device 5 and can be an IC integrated with the control IC with respect to the above-described screen. Touch panel 10. The connection pads (not shown), which face the display device 5 and the substrate 3, respectively, may be arranged so that the display device 5 and the substrate 3 can be connected via the zebra connector 4, similar to the above-mentioned structure with respect to FIG the connecting pad 23 from the sensor 2 and the electrode 31 on the substrate 3. In this case, the electrode 22 from the sensor, the electrode from the display device 5 and the electrode 31 on the substrate 3 facing it are suitably arranged such that no short circuit is caused via the zebra connector 4. Alternatively, the display device 5 and the substrate 3 may be connected using an FPC or the like (not shown). In this way, the circuit for operating the display device 5 is further applied to the substrate 3, so that it is possible to jointly have a substrate on which a circuit for operating the sensor 2 and processing the output signal from the sensor 2 is applied, and a substrate on which the circuit for operating the display device is applied, whereby the device is downsized.
[Method of Manufacturing a Portable Device] Next, an example of a method of manufacturing the portable device 1 will be described. The outer peripheral portion of the display device 5 is placed on the inner peripheral upper surface 43b of the zebra connector 4. As a result, the display device 5 is supported and positioned by the zebra connector 4.
Subsequently, the outer peripheral portion of the sensor 2 is brought into contact with the outer peripheral upper surface 43a of the zebra connector 4, and the outer peripheral portion of the substrate 3 is contacted with the lower surface 44 of the zebra connector 4 contacted. Then, the sensor 2, the substrate 3, and the zebra connector 4 are integrated by a pressing force in a vertical direction (the AA direction) in FIG. 1 using a case, a frame, or the like having a shape corresponding to the touch panel 10 corresponds (not shown). When an appropriate pressure is applied, a predetermined electrode 22 in the sensor 2 and the electrode 31 facing the electrode 22 in the substrate 3 are electrically connected by contact with the conductive portion 45 of the zebra connector 4. The control signal to the sensor 2 and the output signal, which is output in response to an operating input on the sensor 2, are between the sensor 2 and the control IC, which is applied to the substrate 3, via the zebra connector 4 and the Transfer electrode 31.
With the portable device 1 or the touch panel 10 described above, effects exemplified below can be obtained.
Since it is configured in such a way that the sensor 2 and the substrate 3 are connected, which is carried out by pressing, using the zebra connector 4, it is possible that a region for thermocom
CH 714 334 A2 pressure bonding from a connection part and the FPC, which was conventionally necessary, is not required. Therefore, the portable device 1 or the touch panel 10 can be downsized.
Further, it is possible to connect the electrode 22 and the connection pad 23 at the shortest distance without using wirings that extend along the outer periphery of the base material as in the conventional case. Therefore, the impedance of a signal line can be reduced.
In addition, there is no need to bend the base material 21 and there is no interruption problem.
Even if an electrical connection error occurs due to a relative positional deviation or the like between the sensor 2 and the substrate 3, it is only necessary to press using the frame or the like after repositioning or the like. Consequently, when the positional deviation conventionally occurred in the joint portion by thermocompression bonding, a product could not be corrected, and thus it was forced to be discarded, but since it is not necessary to discard the product, the yield in a manufacturing process can be improved ,
<2. Second embodiment>
[0035] Next, a second embodiment will be described. Points described in the first embodiment can also be applied in the second embodiment unless otherwise stated. Fig. 6 is a plan view for explaining the structural example of the sensor (a sensor 2a) according to the second embodiment. The sensor 2a has a rectangular base material 26. The base material 26 is an insulating material such as glass or foil and is transparent to the extent that display device contents can be visually recognized by the display device.
In the second embodiment, transparent electrode patterns 27 and 28 made of the ITO film or the like are provided on a surface of a base material 26. The transparent electrode pattern 27 has four rows of transparent electrode patterns 27a, 27b, 27c and 27d that extend in the X-axis direction and are strung together in the Y-axis direction. The transparent electrode pattern 27 has a plurality of electrodes. For example, the transparent electrode pattern 27a includes electrodes 271, 272, 273, 274 and 275 in order from the side close to an outer edge of the base material 26. Among them, the electrodes 272, 273 and 274 have a rhombic shape (diamond shape) with substantially the same diagonal length, and the electrodes 271 and 275 at both ends have a triangular shape, the rhombic shape being divided by a diagonal line , The same applies to other transparent electrode patterns 27b and the like.
The transparent electrode pattern 28 has four rows of transparent electrode patterns 28a, 28b, 28c and 28d which extend in the Y-axis direction and are strung together in the X-axis direction. The transparent electrode pattern 28 has a plurality of electrodes. For example, the transparent electrode pattern 28a includes electrodes 281, 282, 283, 284 and 285 in order from the side close to an outer edge of the base material 26. Among them, electrodes 282, 283, and 284 are approximately the same size and shape as, for example, electrode 272, and electrodes 281 and 285 at both ends are approximately the same size and shape as, for example, electrode 271. The same applies to other transparent electrode patterns 28b and the like. Note that each electrode that represents the transparent electrode pattern 28 is connected by a known bridge structure (not shown).
In addition to such a mode, for example, a bonding structure can be adopted in which the transparent electrode pattern 27 is provided on one base material from the two base materials, the transparent electrode pattern 28 is provided on the other base material from the two base materials, and these two Base materials are arranged so that they face each other in the Z-axis direction and are bonded by an optical adhesive sheet (OCA (optical clear adhesive) or the like).
The connection pads made of the ITO film or the like are located with the electrodes at both ends (first electrodes in the second embodiment), located at portions close to the outer edges, under the electrodes, which is the transparent electrode pattern 27 represent connected. Further, the connection pads made of the ITO film or the like with the electrodes at both ends (first electrodes in the second embodiment), located at portions close to the outer edges, are below the electrodes constituting the transparent electrode pattern 28 , connected. For example, a rectangular connection pad 29a is connected with a side portion substantially parallel to the outer edge of the base material 26 among three side portions from the electrode 271, which is the transparent electrode pattern 27a. For example, a rectangular connection pad 29b having a side portion substantially parallel to the outer edge of the base material 26 is connected among the three side portions of the electrode 275 which is the transparent electrode pattern 27a. Further, for example, a rectangular connection pad 29c is connected to a side portion that is substantially parallel to the outer edge of the base material 26 among the three side portions of the electrode 281, which is the transparent electrode pattern 28a. For example, a rectangular connection pad 29d is connected to a side portion that is substantially parallel to the outer edge of the base material 26 among the three side portions of the electrode 285, which is the transparent electrode pattern 28a. In order to facilitate understanding, an imaginary dashed line is added to the boundary between the electrode and the connection pad in FIG. 6.
CH 714 334 A2
If it is not necessary to distinguish individual connection pads, they are collectively referred to as the connection pad 29, if appropriate.
The connection pad 29 is connected to the electrode, located at an end portion, among the electrodes constituting the transparent electrode patterns 27 and 28, so that the connection pad 29 in a frame shape along the outer peripheral portion (first outer peripheral portion in the second embodiment) is provided by the base material 26. The outer peripheral portion of the base material 26 means a region near the outer edge of the base material 26. The transparent electrode patterns 27, 28 and the connection pad 29 are formed by the method using, for example, the photolithography method or the laser etching method, wherein however, they can be formed by different methods. Further, the transparent electrode patterns 27, 28 and the connection pad 29 can be formed by a printing method using transparent conductive ink.
The connection pad 29 according to the second embodiment has a width which is substantially equal to the maximum width of the electrode to which the connection pad 29 is bound. For example, in the present embodiment, the maximum width from the electrode is a length of a diagonal line 51 from the electrode. The connection pad 29 has a width 52 that is substantially equal to the length from the diagonal line 51. Substantially equal means equal to or equal to within a range of a small defect that can occur in a manufacturing process. Furthermore, the connection pad 29 has a rectangular shape, which maintains the width 52 to the outside of the base material 26.
Although not shown, the substrate, the zebra connector and the display device have the same structure and the same operation as the first embodiment, except that the overall shape corresponding to the shape (rectangular shape) of the sensor 2a is rectangular. The touch panel according to the second embodiment is configured to include, for example, the sensor 2a, the substrate, and the zebra connector. The touch panel works as a mutual capacitance-type capacitive touch panel that detects a change in electrostatic capacitance between the transparent electrode patterns 27 and 28, each of which functions as a transfer electrode and a pickup electrode.
In the same way as in the first embodiment, each component is integrated with each other by the pressing force. That is, the outer peripheral portion of the display device is placed on the inner peripheral upper surface of the zebra connector. As a result, the display device is carried by and positioned by the zebra connector. Then, the outer peripheral portion of the sensor 2a is brought into contact with the outer peripheral upper surface of the zebra connector, and the outer peripheral portion of the substrate on which the control IC is mounted, and a predetermined wiring pattern is formed , is brought into contact with the lower surface of the zebra connector. Then, the sensor 2a, the substrate and the zebra connector are pressed by the pressing force in the vertical direction (Z-axis direction in Fig. 6) using the housing, the frame, or the like with the shape corresponding to the touch panel , integrated (not shown). If an appropriate pressure is applied, the electrode in the substrate corresponding to the predetermined connection pad 29 in the sensor 2a and the electrode facing the electrode in the substrate will be in contact with the conductive portion of the zebra connector electrically connected. Consequently, the control signal to the sensor 2a and the output signal output in response to the operation input to the sensor 2 are between the sensor 2a and the control IC mounted on the substrate via the zebra connector and the electrode transfer.
According to the second embodiment described above, effects exemplified below can be obtained in addition to the effects obtained by the first embodiment described above.
The connection pad 29 is configured to have the maximum width of the electrode, so that an area of the connection pad 29 can be increased. As a result, a contact area between the sensor 2a and the anisotropic conductor can be increased, and the contact resistance can be decreased. Therefore, the impedance of a signal path from the sensor 2a to the control IC can be further reduced, and it is possible to prevent the detection performance from the touch panel from deteriorating.
<3. modification>
Although the embodiments of one aspect of the present invention are described in detail above, one aspect of the present invention is not limited to the embodiments described above, but various modifications can be made.
In the second embodiment described above, a circuit for operating the display device may further be applied to the substrate, similar to the structure described in the first embodiment. Accordingly, it is possible to share the substrate on which the circuit for operating the sensor 2a and processing the output signal from the sensor 2a is applied, and the substrate on which the circuit for operating the display device is applied.
CH 714 334 A2 In the second embodiment described above, the connection pad 29 may be connected to only one of the electrodes instead of both ends of the transparent electrode pattern. It is also possible to adopt a structure in which the connection pad 29 is expanded from the portion of the width 52 to the outside of the base material 26 to such an extent that it does not come into contact with adjacent connection pads 29. As a result, the area of the connection pad 29 can be made larger. Further, the number of transparent electrode patterns and the number, shape, and the like of the electrodes constituting the transparent electrode patterns can be changed appropriately.
It goes without saying that a structure corresponding to the device to which the touch panel is attached can be added if appropriate. For example, when the touch panel is attached to the wristwatch type portable device as in the embodiment described above, the portable device may have a structure of a band, a button, and the like.
As described in the above-described embodiment, the capacitive touch panel of one aspect of the present invention may be the self-capacitance type capacitive touch panel or the mutual capacitance-type capacitive touch panel, and may also be on a resistance film type touch panel is attached.
The structures, methods, processes, shapes, materials, numerical values and the like mentioned in the above-described embodiments and modifications are only examples, and different structures, methods, processes, shapes, materials, numerical values and the like can be used if necessary, or they can be replaced with known ones. Furthermore, the structures, methods, processes, shapes, materials, numerical values and the like in the embodiments and modifications can be combined with one another as long as there is no technical contradiction.
