  First, an outline of a touch panel to which the wiring structure according to the embodiment is applied will be described with reference to FIGS. 1A to 1C. FIG. 1A is a perspective view showing a schematic configuration of a touch panel according to an embodiment. FIG. 1B is a view showing a schematic configuration of a conductive film according to the embodiment. FIG. 1C is an enlarged view of a conductive film according to an embodiment. Note that, in order to make the description easy to understand, a plurality of drawings including FIG. 1A are attached with a three-dimensional orthogonal coordinate system in which the stacking direction of each component of the touch panel is a Z axis.

  As shown in FIG. 1A, the touch panel 1 according to the embodiment includes a panel 2, a conductive film 3, and a display device 4. The touch panel 1 can be used, for example, as a navigation device mounted on a vehicle, or a touch panel of a smartphone, a tablet terminal, a PC (Personal Computer), an electronic blackboard, a wearable terminal, or the like.

  The panel 2 is a light transmitting plate-like member, and for example, a material such as glass or a transparent resin can be used. The display device 4 displays an arbitrary image such as, for example, a moving image, a still image, or a text document. The conductive film 3 is a film-like member provided with an electrode for touch position detection.

  Specifically, as shown in FIG. 1B, the conductive film 3 includes a wiring region 30 in which a conducting wire is patterned. The wiring area 30 includes a first electrode area 31, a second electrode area 32, a ground area 33, a signal line area 34, an isolation area 35 and a dummy area 36.

  The first electrode region 31 is, for example, a drive electrode (an example of a first electrode), receives a signal from a control circuit (not shown) via a signal line of the signal line region 34, and outputs the signal to the second electrode region 32.

  The first electrode region 31 is, for example, a mesh pattern (see FIG. 1C) region in which a plurality of conducting wires intersect. In addition, the first electrode region 31 has a protrusion that protrudes toward the second electrode region 32, and a signal is output from the protrusion to the second electrode region 32. In addition, in FIG. 1B, although the above-mentioned protrusion part of the 1st electrode area | region 31 is one, two or more may be sufficient.

  In addition, the first electrode region 31 is also provided at a position symmetrical with the Y axis as a symmetry axis at positions sandwiching the signal line region 34. That is, one pair of first electrode regions 31 is provided to sandwich the signal line region 34, and a plurality of the first electrode regions 31 are arranged in the row direction which is the Y-axis direction. The plurality of first electrode regions 31 arranged in the row direction are connected by the same conductor and then connected to a control circuit (not shown). Note that FIG. 1B shows the case where three pairs of first electrode regions 31 are provided in the row direction as an example, but may be two or less, or four or more.

  A plurality of first electrode regions 31 are also arranged in the column direction which is the X-axis direction. Specifically, the first electrode regions 31 are arranged in line-symmetrical positions with the X axis as a symmetry axis at positions sandwiching the separation region 35. Although FIG. 1B shows the case where five first electrode regions 31 are arranged in the X-axis direction, the number may be four or less, or five or more.

  The second electrode region 32 is, for example, a sensing region (an example of a second electrode), and outputs a signal input from the first electrode region 31 to the control circuit. Further, the second electrode region 32 is a region of mesh pattern as in the case of the first electrode region 31. Further, the second electrode regions 32 extend in the column direction which is the X-axis direction of the wiring region 30, and are provided in a pair so as to sandwich the signal line region 34, and a plurality are arranged in the row direction.

  The touch panel 1 is a so-called capacitive touch panel that detects a touch position based on a potential difference between a signal output from the control circuit (not shown) to the first electrode area 31 and a signal input from the second electrode area 32. Furthermore, the touch panel 1 is a touch panel of a one-layer circuit in which the first electrode region 31 and the second electrode region 32 are provided in the same layer.

  The touch panel 1 is not limited to the electrostatic capacitance type, and may be another type such as a resistance film type, as long as it uses a lead. Further, the touch panel 1 is not limited to a one-layer circuit, and may be a two-layer circuit.

  The ground region 33 is a region that functions as a ground (ground), and is a region serving as a reference potential point of a control circuit (not shown). The ground region 33 is provided so as to sandwich the dummy region 36 with the second electrode region 32.

  The signal line area 34 is an area in which a signal line connecting the first electrode area 31 and the control circuit is formed. Specifically, signal line region 34 is connected to each of the plurality of first electrode regions 31 arranged in the row direction and the column direction, and goes out of the region from the lower end side which is the Y axis negative direction side of interconnection region 30. Connected to the control circuit.

  In the signal line area 34, only one signal line is connected to the pair of first electrode areas 31 at the upper end which is the Y-axis positive direction side. Specifically, four end sides of the wiring area 30 are surrounded by the conducting wire, and in the signal line area 34, one signal line is connected to the conducting wire at the upper end which is the Y-axis positive direction side, Are connected to the pair of first electrode regions 31 via

  In addition, the signal line region 34 is a region of a zigzag pattern (see FIG. 1C) in which a plurality of conductive wires are arranged to be bent. In the signal line region 34, the conducting wire is disconnected so that one signal line is connected to one first electrode region 31.

  The dummy region 36 is a region that electrically separates the first electrode region 31 and the second electrode region 32, and the second electrode region 32 and the ground region 33. The dummy area 36 is an area of a mesh pattern as in the case of the first electrode area 31 and the second electrode area 32. In addition, the dummy region 36 is separated from the first electrode region 31 and the second electrode region 32 by leaving a gap.

  The separation region 35 is a region that separates two first electrode regions 31 (an example of a partial region) arranged in the column direction. Here, the separation region 35 will be further described using FIG. 1C. FIG. 1C shows an enlarged view of the separation region 35 and the periphery thereof. Further, in FIG. 1C, a first conducting wire 10 arranged along a first direction orthogonal to each other and a second conducting wire 11 arranged along a second direction different from the first direction. And a closed region 20 surrounded by the first conducting wire 10 and the second conducting wire 111. Further, in FIG. 1C, the two first electrode regions 31 a and 31 b are separated by the separation region 35.

  As shown in FIG. 1C, the separation region 35 is formed by the openings 40a to 40f which are portions where the first conducting wire 10 and the second conducting wire 11 are broken. More specifically, the separation region 35 is formed by connecting the adjacent closed regions 20 by the openings 40 a to 40 f. That is, the separation region 35 is separated into the first electrode region 31 a on the positive side in the X-axis positive direction and the first electrode region 31 b on the negative side in the X-axis direction by the plurality of closed regions 20 being continuous. In addition, below, when not distinguishing the opening parts 40a-40f, it may describe as the opening part 40. FIG.

  In the example shown in FIG. 1C, although the first conducting wire 10 and the second conducting wire 11 are orthogonal to each other, they do not necessarily have to be orthogonal, and if the first conducting wire 10 and the second conducting wire 11 cross each other It is enough.

  Here, the conventional wiring structure will be described. In the conventional wiring structure, the conducting wire is broken in a straight line (for example, a straight line parallel to the Y-axis direction). Specifically, the electrode regions are separated such that the openings are linearly arranged along the Y-axis direction.

  However, for example, in the case of using a conducting wire made of an opaque material, when the conducting wire is broken in a straight line, the openings are arranged in a straight line, and the separation region is made straight by a so-called illusion effect (a kind of Ehrenstein illusion) There was a risk that so-called bone appearance appeared to be present. Such a bone appearance is particularly prominent in the leads of the opaque material, but may occur in the leads of the transparent material, which contributes to the deterioration of the appearance of the touch panel product.

  Therefore, in the wiring structure according to the embodiment, the openings 40a to 40f are not arranged in a straight line. Specifically, in the wiring structure according to the embodiment, the separation region 35 is such that, for three consecutive openings 40 a to 40 f via the closed region 20, the remaining one deviates from the straight line passing through any two. Be placed.

  For example, when three consecutive openings 40a, 40b, and 40c among the six openings 40a to 40f are viewed, the openings 40a are not located on a straight line connected by the openings 40b and the openings 40c. .

  Similarly, the opening 40b is not positioned on the straight line connected by the opening 40a and the opening 40c, and the opening 40c is not positioned on the straight line connected by the opening 40a and the opening 40b.

  That is, three continuous openings 40a, 40b, and 40c are provided so as not to line up on a straight line. And as shown to FIG. 1C, even if it sees also about three continuous combinations of six opening parts 40a-40f, it arrange | positions so that it may not line up on a straight line similarly.

  Thereby, when the six openings 40a to 40f are connected, the three or more openings 40a to 40f are not arranged in a straight line, so that the illusion effect is not generated, and the separation region is formed by the plurality of openings 40a to 40f. 35 does not look straight. Therefore, according to the wiring structure according to the embodiment, the occurrence of bone appearance can be suppressed.

  Furthermore, in the mesh pattern in which the first conducting wire 10 and the second conducting wire 11 intersect, the bone structure in the mesh pattern according to the embodiment is applied because bone visibility is more easily generated due to the crossing of the conducting wires. It is possible to efficiently suppress the occurrence of the appearance.

  In the wiring method of the wiring structure according to the embodiment, after patterning the first conducting wire 10 and the second conducting wire 11 on the conductive film 3, the positions to be the openings 40a to 40f are not masked with a resist. This can be realized by conducting wire removal such as etching.

  Next, a method of positioning the opening 40 will be described with reference to FIG. FIG. 2 is a view for explaining a method of positioning the opening 40 according to the embodiment. In FIG. 2, a method of positioning the opening 40 (hereinafter referred to as the opening 40c) continuous with the two openings 40a and 40b will be described.

  First, as shown in FIG. 2, it is assumed that two openings 40a and 40b of the closed region 20 at the left end are determined. In such a case, in order to determine the position of the opening 40c continuous with the openings 40a and 40b, first, a straight line L passing through the two openings 40a and 40b is drawn.

  Then, the opening 40 c is determined at a position other than the intersection point P of the straight line L and the first conducting wire 10 a. At this time, the opening 40c is preferably at a position different from the intersection position PIa of the first conducting wire 10a and the second conducting wire 11a and the intersection position PIb of the first conducting wire 10b and the second conducting wire 11a.

  This is because, if the openings 40c are provided at the intersection positions PIa and PIb, a circle that does not originally exist appears to be present due to an optical illusion effect. Therefore, by forming the openings 40c at positions other than the intersection positions PIa and PIb, the occurrence of bone appearance can be prevented.

  Next, the positioning of the opening 40 will be further described with reference to FIGS. 3 and 4. FIGS. 3 and 4 are diagrams for explaining the positioning method of the opening 40 according to the embodiment. In FIG. 3 and FIG. 4, each of the three openings 40 (openings 40-1 to 3) is indicated by a circle (ovoid).

  Moreover, in FIG. 3, the case where three continuous opening parts 40-1-3 are formed only in the 1st conducting wire 10 is shown. Further, in FIG. 4, of the three consecutive openings 40-1 to 3, two openings 40-1 and 2 are formed in the first conducting wire 10, and the opening 40-3 is the second conducting wire 11. It shows the case where it is formed.

  First, with reference to FIG. 3, positioning of the openings 40-1 to 3 when formed only in the first conductive wire 10 will be described. In the case of “forming only on the first conducting wire 10”, all the plurality of openings 40 (openings 40a to 40f in FIG. 1C as an example, for example) are formed only on the first conducting wire 10 The invention is not limited thereto, and it is sufficient if only one of the combinations of three consecutive openings 40-1 to 3 present in the plurality of openings 40 is formed in the first conductive wire 10.

  As shown in FIG. 3, the two openings 40-1 and 40-3 have substantially the same distance D1 to one intersection position PI2, and the distance D2 to the intersection position PI2 of the remaining openings 40-2 It is different from

  That is, by changing the distances D1 and D2 of the three consecutive openings 40-1 to 40-3, they are prevented from being aligned on a straight line. Thereby, it becomes possible to form three continuous opening parts 40-1-3 only in the 1st lead 10.

  Furthermore, the openings 40-1 to 3 are formed only in the first conducting wire 10, that is, by arranging three continuous openings 40-1 to 3 along the extending direction of the second conducting wire 11, The lines connecting the openings 40-1 to 3 are camouflaged so as to be dissolved in the second conducting wire 11, so that the appearance of bone appearance can be further suppressed.

  Furthermore, the angle θ between the opening 40-1 and the opening 40-3 centered on the opening 40-2 is preferably as acute as possible. Specifically, the distance D2 of the opening 40-2 is made longer, that is, arranged closer to the intersection position PI1 opposite to the intersection position PI2. Further, the distance D1 between the opening 40-1 and the opening 40-3 is shorter, that is, closer to the intersection position PI2. As a result, the broken line connecting the three continuous openings 40-1 to 40 becomes more difficult to see as a straight line, so that the occurrence of bone appearance can be suppressed.

  Although the example shown in FIG. 3 shows the case where the distance D1 between the opening 40-1 and the opening 40-3 is the same, the distance D1 between the opening 40-1 and the opening 40-3 is different. May be

  Although FIG. 3 illustrates the case where the three continuous openings 40-1 to 3 are provided only in the first conducting wire 10, it is needless to say that the three consecutive openings 40-1 to 3 are the second. It may be provided only on the conductor 11.

  Next, with reference to FIG. 4, positioning of the openings 40-1 to 3 when the three continuous openings 40-1 to 3 are formed in the first conductive wire 10 and the second conductive wire 11 will be described. .

  In FIG. 4, the case where the opening 40-1 and the opening 40-2 are formed in the first conductive wire 10 and the opening 40-3 is formed in the second conductive wire 11 is shown.

  As shown in FIG. 4, when the two openings 40-1 and 40-2 are formed in the first conducting wire 10 and the remaining openings 40-3 are formed in the second conducting wire 11, the openings 40 are formed. -3 is preferably formed around the center of two adjacent crossing points PI2.

  That is, it is preferable that the difference between the distance D3 and the distance D4 to each of the intersection positions PI2 of the openings 40-3 be close to zero. Thus, even when the amount of removal increases due to an error when etching the second conducting wire 11 in the manufacturing stage, removal of the intersection position PI2 can be prevented.

  When the opening 40-3 needs to be disposed at a position other than the central periphery of the second conducting wire 11, the opening 40-3 is preferably formed at a position where the distance D 3 is shorter than the distance D 4. As a result, the angle θ between the opening 40-1 and the opening 40-3 centered on the opening 40-2 is more acute, so that the appearance of bone appearance can be further suppressed.

  Next, the wiring method of the wiring structure will be described in the embodiment with reference to FIG. FIG. 5 is a flowchart showing the procedure of the wiring method of the wiring structure according to the embodiment. The wiring method shown in FIG. 5 is executed by, for example, a worker (or a designer of a substrate) (not shown) and a working robot.

  As shown in FIG. 5, in the wiring method according to the embodiment, first, a wiring area 30 including a closed area 20 surrounded by a plurality of conducting wires and a plurality of conducting wires is formed (step S101). The wiring region 30 is formed, for example, by patterning a conducting wire so as to have a mesh pattern or a zigzag pattern.

  Subsequently, in the wiring method according to the embodiment, a plurality of closed regions 20 are continued by the opening 40 to form the separation region 35 for separating the wiring region 30 into a plurality of partial regions (for example, the first electrode region 31). (Step S102), and the wiring method is completed. The separation region 35 is formed by breaking the conductive wire of the wiring region 30 to form the opening 40 and connecting a plurality of adjacent closed regions 20.

  In step S102, when forming the openings 40, the remaining three are separated from the straight line passing through any two of the three openings 40 continuous through the closed region 20.

  As described above, the wiring structure according to the embodiment includes the wiring region 30 and the separation region 35. Wiring area 30 includes closed area 20 surrounded by a plurality of conducting wires 10 and 11 and a plurality of conducting wires 10 and 11. The separation region 35 separates the wiring region 30 into a plurality of partial regions (first electrode regions 31) by the plurality of closed regions 20 being continuous by the openings 40 where the conducting wires 10 and 11 are broken. In addition, the separation area 35 is arranged such that, for three consecutive openings 40 through the closed area 20, the remaining one is out of the straight line passing through any two. Thereby, the three or more openings 40 are not arranged in a straight line, so that the illusion effect is not generated, and the plurality of openings 40 are not seen in a straight line. .

  In the embodiment described above, the separation region 35 for separating the mesh pattern where the first conducting wire 10 and the second conducting wire 11 intersect is described, but the separation region 35 is not limited to the mesh pattern, A zigzag pattern such as the signal line area 34 may be separated. This point will be described with reference to FIG.

  FIG. 6 is a view showing a separation area 35 according to a modification. In FIG. 6, a zigzag pattern in which the first conducting wire 10 and the second conducting wire 11 bend at right angles at the crossing position PI is shown as an example. The first conducting wire 10 and the second conducting wire 11 are not limited to bending at a right angle at the intersection position PI, but may be bent at an acute angle or an obtuse angle. Further, the distance between the crossing positions PI of the first conducting wire 10 and the second conducting wire 11 may be the same as or different from each other. Further, the closed region 20 shown in FIG. 6 is surrounded by the conductive wires provided on the above-described four end sides of the wiring region 30 and the first conductive wire 10 and the second conductive wire 11.

  As shown in FIG. 6, in the case where only the second conducting wire 11 is formed, for example, three consecutive openings 40 do not line up on a straight line by changing the distance D5 to the intersection position PI. Let's do it. Thus, the signal line area 34 is separated into, for example, a signal line connected to the first electrode area 31 and a dummy area not connected to the first electrode area 31. Then, since the openings 40 of the separation region 35 corresponding to the boundary between the signal line and the dummy region are not aligned on a straight line, it is possible to suppress the occurrence of bone appearance.

  Although FIG. 6 shows the case where the opening 40 is formed only in the second conducting wire 11, it may be formed only in the first conducting wire 10, and the first conducting wire 10 and the second conducting wire 11 may be formed. It may be formed on both sides, as long as three consecutive lines do not line up on a straight line.

  In the above, the first conducting wire 10 and the second conducting wire 11 are arranged along a predetermined regularity like a mesh pattern or a zigzag pattern, but the first conducting wire 10 and the second conducting wire 11 are It may be an irregularly arranged pattern. Moreover, the 1st conducting wire 10 and the 2nd conducting wire 11 may be not only a straight line but a curve.

  In the embodiment described above, the so-called single-layer circuit touch panel 1 in which the first electrode area 31 and the second electrode area 32 are formed in one wiring area 30 has been described. May be Here, the touch panel 1 of the two-layer circuit will be described with reference to FIGS. 7 and 8.

  7 and 8 are diagrams showing a touch panel 1 according to a modification. FIG. 7 shows a schematic front view of the touch panel 1, and FIG. 8 shows an enlarged view of the separation area 35 shown in FIG.

  As shown in FIG. 7, in the touch panel 1 of a two-layer circuit, two layers of conductive films 3a and 3b are laminated. Specifically, the conductive film 3a includes the wiring area 30a in which the first electrode area 31 is formed, and the conductive film 3b includes the wiring area 30b in which the second electrode area 32 is formed.

  Each of the first electrode region 31 and the second electrode region 32 is partitioned, for example, in a rhombus shape, and each is arranged in a checkered pattern. Then, as shown in FIG. 8, in the separation region 35 which is a boundary between the first electrode region 31 and the second electrode region 32, a gap is formed in top view in order to enable signal exchange.

  Specifically, as shown in FIG. 8, a gap is formed by setting a predetermined distance between the opening 40 of the first electrode region 31 and the opening 40 of the second electrode region 32. If such a gap is linear, there is a possibility that bones may appear.

  So, in the touch panel 1 which concerns on a modification, it is made for continuous three opening parts 40 not to line up on a straight line about each opening part 40 of the 1st electrode field 31 and the 2nd electrode field 32. As shown in FIG. Thereby, in the touch panel 1 of the two-layer circuit, it is possible to prevent the deterioration of the appearance of the product due to the bone appearance.

  Further, in the example shown in FIG. 8, it is preferable that all the distances D6 between the openings 40 of the first electrode region 31 and the openings 40 of the second electrode region 32 be equal. In other words, the boundary formed by the opening 40 of the first electrode region 31 and the boundary formed by the opening 40 of the second electrode region 32 have substantially the same shape. This can prevent the occurrence of unevenness in the current value flowing between the first electrode region 31 and the second electrode region 32.

  In FIG. 8, although the three continuous portions of the openings 40 in both the first electrode region 31 and the second electrode region 32 are positioned so as not to align on a straight line, the first electrode region 31 and the second electrode region 32 are positioned. Only one of the openings 40 may be positioned. As a result, since the other opening 40 can be disconnected linearly without being positioned, the design cost can be reduced.

  Further effects and modifications can be easily derived by those skilled in the art. Thus, the broader aspects of the invention are not limited to the specific details and representative embodiments represented and described above. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
