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) through the signal line of the signal line region 34 , and outputs the signal to the second electrode region 32 .

Also, the first electrode region 31 is, for example, a mesh pattern (see FIG. 1C) region where a plurality of conductors intersect. Also, the first electrode region 31 has a projecting portion projecting toward the second electrode region 32 , and a signal is output from the projecting portion toward the second electrode region 32 . In FIG. 1B, the first electrode region 31 has one projecting portion, but may have two or more projecting portions.

In addition, the first electrode regions 31 are also provided at positions that sandwich the signal line region 34 and are symmetrical with respect to the Y-axis. That is, a pair of first electrode regions 31 are provided so as to sandwich the signal line region 34, and a plurality of first electrode regions 31 are arranged in the row direction, which is the Y-axis direction. A 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). Although FIG. 1B shows an example in which three pairs of first electrode regions 31 are provided in the row direction, the number 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 respect to the X-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. Also, the second electrode region 32 is a mesh pattern region, like 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 pairs so as to sandwich the signal line region 34, and are arranged in plurality 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 to the first electrode region 31 by a control circuit (not shown) and a signal input from the second electrode region 32 . Furthermore, the touch panel 1 is a one-layer circuit touch panel in which the first electrode region 31 and the second electrode region 32 are provided in the same layer.

It should be noted that the touch panel 1 is not limited to the capacitive type, and may be of another type such as a resistive film type, as long as it uses conducting wires. Moreover, the touch panel 1 is not limited to a one-layer circuit, and may be a two-layer circuit.

The ground area 33 is an area that functions as a ground (earth) and serves as a reference potential point for 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 region 34 is a region where a signal line connecting the first electrode region 31 and the control circuit is formed. Specifically, the 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 extends out of the wiring region 30 from the lower end side of the wiring region 30 in the Y-axis negative direction. connected to the control circuit.

Further, in the signal line region 34, only one signal line is connected to the pair of first electrode regions 31 at the upper end on the Y-axis positive direction side. Specifically, four edges of the wiring region 30 are surrounded by conductors, and in the signal line region 34, one signal line is connected to a conductor at the upper end in the positive Y-axis direction. are connected to the pair of first electrode regions 31 via the .

Also, the signal line region 34 is a region of a zigzag pattern (see FIG. 1C) in which a plurality of conducting wires are arranged in a bent manner. The signal line region 34 is broken 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 a mesh pattern area, like the first electrode area 31 and the second electrode area 32 . Also, the dummy region 36 is separated from each of the first electrode region 31 and the second electrode region 32 by leaving a gap.

The isolation region 35 is a region that separates the two first electrode regions 31 (an example of partial regions) aligned in the column direction. Here, the isolation region 35 will be further described with reference to FIG. 1C. FIG. 1C shows an enlarged view of the isolation region 35 and its periphery. In addition, in FIG. 1C, a first conductor 10 arranged along a first direction orthogonal to each other and a second conductor 11 arranged along a second direction different from the first direction are shown. , and a closed area 20 surrounded by a first conductor 10 and a second conductor 111. FIG. Also, 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, isolation regions 35 are formed by openings 40a-40f, which are portions where first conductor 10 and second conductor 11 are disconnected. More specifically, the separation region 35 is formed by connecting the adjacent closed regions 20 with the openings 40a to 40f. In other words, the separation region 35 is separated into the first electrode region 31a on the X-axis positive direction side and the first electrode region 31b on the X-axis negative direction side by connecting a plurality of closed regions 20 . In the following description, the openings 40a to 40f may be referred to as the openings 40 when they are not distinguished from each other.

In the example shown in FIG. 1C, the first conductor 10 and the second conductor 11 are orthogonal to each other, but they do not necessarily have to be orthogonal. Enough.

Here, a 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 by arranging the openings in a straight line along the Y-axis direction.

However, for example, when a conducting wire made of an opaque material is used, if the conducting wire is cut in a straight line, the openings are arranged in a straight line, and the so-called optical illusion effect (a type of Ehrenstein illusion) causes the separation area to appear as a straight line. There is a possibility that so-called bone appearance, which looks as if it exists, occurs. Such bone appearance is particularly conspicuous in conductive wires made of opaque material, but it may also occur in conductive wires made of transparent material, which is one of the factors that impair the appearance of touch panel products.

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 formed such that the remaining one of the three openings 40a to 40f that are continuous through the closed region 20 is off the straight line passing through any two of them. placed.

For example, when looking at three continuous openings 40a, 40b, and 40c among the six openings 40a to 40f, the opening 40a is not located on the straight line connecting the openings 40b and 40c. .

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

That is, the three continuous openings 40a, 40b, and 40c are provided so as not to line up on a straight line. Then, as shown in FIG. 1C, any three consecutive combinations of the six openings 40a to 40f are similarly arranged so as not to line up on a straight line.

As a result, when the six openings 40a to 40f are connected, three or more openings 40a to 40f are not arranged in a straight line, so that an optical illusion effect does not occur, and the plurality of openings 40a to 40f separate regions. 35 never looks straight. Therefore, according to the wiring structure according to the embodiment, it is possible to suppress the occurrence of visible bones.

Furthermore, in a mesh pattern in which the first conductor 10 and the second conductor 11 intersect, bones are more likely to appear due to the crossing of the conductors. It is possible to efficiently suppress the appearance of the appearance.

In the wiring method of the wiring structure according to the embodiment, after patterning the first conductor 10 and the second conductor 11 on the conductive film 3, the positions to be the openings 40a to 40f are not masked with a resist. In addition, it can be realized by removing the conductive wire by etching or the like.

Next, a method for positioning the opening 40 will be described with reference to FIG. FIG. 2 is a diagram illustrating a positioning method for the opening 40 according to the embodiment. In FIG. 2, a method of positioning an opening 40 (hereinafter referred to as an opening 40c) that is 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 this case, in order to determine the position of the opening 40c that is 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 40c is determined at a position other than the intersection point P between the straight line L and the first conducting wire 10a. At this time, the opening 40c is preferably located at a position different from the intersection position PIa of the first conductor 10a and the second conductor 11a and the intersection position PIb of the first conductor 10b and the second conductor 11a.

This is because if the openings 40c were provided at the intersection points PIa and PIb, it would appear that a circle that does not exist originally exists due to an optical illusion effect. Therefore, by forming the opening 40c at a position other than the intersection positions PIa and PIb, it is possible to prevent the occurrence of visible bones.

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

Also, FIG. 3 shows a case where three continuous openings 40-1 to 40-3 are formed only in the first conductor 10. As shown in FIG. Further, in FIG. 4, of the three continuous openings 40-1 to 40-3, two openings 40-1 and 40-2 are formed in the first conductor 10, and the opening 40-3 is formed in the second conductor 11. is formed in

First, positioning of the openings 40-1 to 40-3 when formed only in the first conductor 10 will be described with reference to FIG. It should be noted that "when formed only in the first conductor 10" means that all of the plurality of openings 40 (openings 40a to 40f, taking FIG. 1C as an example) are formed only in the first conductor 10. The present invention is not particularly limited, and it is sufficient that any combination of the three continuous openings 40-1 to 40-3 present in the plurality of openings 40 is formed only in the first conductor 10. FIG.

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 opening 40-2. 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 lining up on a straight line. Thereby, it is possible to form three continuous openings 40-1 to 40-3 only in the first conductor 10. FIG.

Furthermore, by forming the openings 40-1 to 40-3 only in the first conductor 10, that is, by arranging three consecutive openings 40-1 to 40-3 along the extending direction of the second conductor 11, Since the lines connecting the openings 40-1 to 40-3 are camouflaged so as to blend into the second conductors 11, the appearance of bones can be further suppressed.

Furthermore, it is preferable that the angle θ between the opening 40-1 and the opening 40-3 with the opening 40-2 as the center be as acute as possible. Specifically, the distance D2 of the opening 40-2 is made longer, that is, it is placed closer to the intersection point PI1 on the side opposite to the intersection point PI2. Also, the distance D1 between the openings 40-1 and 40-3 is made shorter, that is, they are arranged closer to the intersection point PI2. As a result, the polygonal line connecting the three continuous openings 40-1 to 40-3 becomes more difficult to see as a straight line, so that it is possible to suppress the occurrence of visible bones.

Although the example shown in FIG. 3 shows the case where the distance D1 between the openings 40-1 and 40-3 is the same, the distances D1 between the openings 40-1 and 40-3 are different. may

Also, in FIG. 3, the case where the three consecutive openings 40-1 to 40-3 are provided only in the first conductor 10 has been described, but of course the three consecutive openings 40-1 to 40-3 are provided in the second conductor 10. It may be provided only on the conducting wire 11 .

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

FIG. 4 shows the case where the openings 40-1 and 40-2 are formed in the first conductor 10 and the opening 40-3 is formed in the second conductor 11. FIG.

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

That is, it is preferable that the difference between the distance D3 and the distance D4 to each intersection point PI2 of the opening 40-3 is close to zero. As a result, even if the removal amount is increased due to an error when etching the second conductor 11 in the manufacturing stage, it is possible to prevent the intersection point PI2 from being removed.

If the opening 40-3 needs to be arranged at a position other than the central periphery of the second conductor 11, it is preferably formed at a position where the distance D3 is shorter than the distance D4. As a result, the angle θ formed by the openings 40-1 and 40-3 with the opening 40-2 as the center becomes more acute, thereby further suppressing the occurrence of visible bones.

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

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

Subsequently, in the wiring method according to the embodiment, a plurality of closed regions 20 are connected by the openings 40 to form separation regions 35 that separate the wiring region 30 into a plurality of partial regions (for example, the first electrode regions 31). (step S102) to complete the wiring method. The isolation region 35 is formed by disconnecting the conductive wire of the wiring region 30 to form an opening 40 and connecting a plurality of adjacent closed regions 20 .

In step S102, when the openings 40 are formed, three openings 40 that are continuous through the closed region 20 are arranged with the remaining one removed from a straight line passing through any two.

As described above, the wiring structure according to the embodiment includes the wiring region 30 and the isolation region 35 . The wiring area 30 includes a plurality of conductors 10 and 11 and a closed area 20 surrounded by the plurality of conductors 10 and 11 . The separation region 35 separates the wiring region 30 into a plurality of partial regions (first electrode regions 31) by connecting a plurality of closed regions 20 with openings 40 where the conductors 10 and 11 are disconnected. In addition, the separation region 35 is arranged such that the remaining one of the three openings 40 that are continuous through the closed region 20 is out of line with any two of the openings 40 . As a result, since three or more openings 40 are not arranged in a straight line, an optical illusion effect does not occur, and a plurality of openings 40 do not appear to be straight, thereby suppressing the appearance of bones. .

In the above-described embodiment, the separation region 35 that separates the mesh pattern in which the first conductor 10 and the second conductor 11 intersect has been described, but the separation region 35 is not limited to the mesh pattern. A zigzag pattern such as the signal line region 34 may be separated. This point will be described with reference to FIG.

FIG. 6 is a diagram showing an isolation region 35 according to a modification. FIG. 6 shows an example of a zigzag pattern in which the first conductor 10 and the second conductor 11 are bent at right angles at the intersection point PI. In addition, the first conducting wire 10 and the second conducting wire 11 are not limited to being bent at a right angle at the intersection point PI, and may be bent at an acute angle or at an obtuse angle. Also, the distance between the intersection positions PI of the first conducting wire 10 and the second conducting wire 11 may be the same or different. The closed region 20 shown in FIG. 6 is surrounded by the conductors provided at the above-described four edges of the wiring region 30, the first conductor 10 and the second conductor 11. As shown in FIG.

As shown in FIG. 6, when only the second conductor 11 is formed in the openings 40, for example, by changing the distance D5 to the crossing position PI, three consecutive openings 40 are not aligned on a straight line. make it Thereby, the signal line region 34 is separated into, for example, a signal line connected to the first electrode region 31 and a dummy region not connected to the first electrode region 31 . By not arranging the openings 40 of the separation area 35 corresponding to the boundary line between the signal line and the dummy area on a straight line, it is possible to suppress the occurrence of visible bones.

Although FIG. 6 shows the case where the opening 40 is formed only in the second conductor 11 , it may be formed only in the first conductor 10 . may be formed on both sides, and it is sufficient if the three continuous lines are not aligned on a straight line.

In the above description, the first conductors 10 and the second conductors 11 are arranged according to a predetermined regularity such as a mesh pattern or a zigzag pattern, but the first conductors 10 and the second conductors 11 It may be an irregularly arranged pattern. Moreover, the first conducting wire 10 and the second conducting wire 11 are not limited to straight lines, and may be curved lines.

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

7 and 8 are diagrams showing a touch panel 1 according to a modification. 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 having a two-layer circuit, two layers of conductive films 3a and 3b are laminated. Specifically, the conductive film 3a has a wiring region 30a in which the first electrode region 31 is formed, and the conductive film 3b has a wiring region 30b in which the second electrode region 32 is formed.

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

Specifically, as shown in FIG. 8, a gap is formed by setting a predetermined distance D6 between the opening 40 of the first electrode region 31 and the opening 40 of the second electrode region 32 . If such a gap becomes linear, there is a risk that the bone will be visible.

Therefore, in the touch panel 1 according to the modified example, the three continuous openings 40 of the openings 40 of each of the first electrode region 31 and the second electrode region 32 are arranged so as not to be aligned on a straight line. As a result, in the touch panel 1 of the two-layer circuit, it is possible to prevent deterioration of the appearance of the product due to bone appearance.

Moreover, in the example shown in FIG. 8, it is preferable that the distances D6 between the openings 40 of the first electrode region 31 and the openings 40 of the second electrode region 32 are all equal. In other words, the boundary line formed by the opening 40 of the first electrode region 31 and the boundary line formed by the opening 40 of the second electrode region 32 have substantially the same shape. As a result, it is possible to prevent unevenness in the value of the current flowing between the first electrode region 31 and the second electrode region 32 .

In FIG. 8, the openings 40 of both the first electrode region 31 and the second electrode region 32 are positioned such that the three continuous openings 40 are not arranged in a straight line. Only one of the openings 40 may be positioned. As a result, since the other opening 40 can be cut in a straight line without positioning, the design cost can be reduced.

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