Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transparent touch panel and a method for manufacturing the same.

[0002]

2. Description of the Related Art LCD (Liquid Crystal Display) and CRT
Some machines with display devices such as (CRT)
2. Description of the Related Art There is a type in which input is enabled by touching a screen of a display device with a finger or an input pen (for example, a cash dispenser installed in a bank or the like). This type of machinery has a structure in which a transparent touch panel is provided on a screen of a display device. As shown in FIGS. 12 to 14, the transmissive touch panel 100 includes a transmissive fixed electrode member 101 and a transmissive and fixed electrode member 101 that is opposed to the surface of the fixed electrode member 101 via a non-contact gap 102. A flexible movable electrode member 103 and a bonding member 104 interposed between the two electrode members 101 and 103 in an arrangement surrounding the non-contact gap 102 to maintain a facing distance therebetween.
And

[0003] The fixed electrode member 101 includes a movable electrode member 1.
Electrodes 106 are provided on two opposing sides in the plane facing 03, and the bending span (length in the plane direction) of movable electrode member 103 does not become too large within a range sandwiched by these electrodes 106. Dot spacers 107 (shown only in FIG. 14) are provided in a dotted manner. On the other hand, the movable electrode member 103 has a fixed electrode member 1 in a plane facing the fixed electrode member 101.
The electrode 1 is located on the two opposite sides that do not match the electrode 106
08 is provided.

Then, each electrode 10 of the fixed electrode member 101
6 and the movable electrode member 103
And a conducting wire 111 drawn out from each of the electrodes 108 is connected to a controller (not shown) via a connector tail 112 provided toward the outer peripheral portion of the panel. Therefore, when the movable electrode member 103 is pressed from the front surface side and the back surface of the movable electrode member 103 contacts the surface of the fixed electrode member 101, the contact point is determined by the potential difference between the two electrodes 106 in the fixed electrode member 101. The coordinates of the contact point (input position) are recognized as a result calculated from the potential difference between the two electrodes 108 of the movable electrode member 103.

[0005] A communication hole 115 for opening the non-contact gap 102 between the two electrode members 101 and 103 to the outside in a direction crossing the bonding member 104 is provided in the outer peripheral portion of the panel of the touch panel 100. . The communication hole 115 is used as an air hole for keeping the non-contact gap 102 and the outside air in a pressure balanced state. In many cases, only one air hole is provided. By the way, Japanese Patent No. 3011697 discloses that the fixed electrode member 101 is formed of a glass substrate, and that the movable electrode member 103 is a touch panel 100 formed of a film as a substrate. At the manufacturing stage, the movable electrode member 10
3 describes that the outer peripheral portion of the fixed electrode member 101 is cut by a laser beam, and that the outer peripheral portion of the fixed electrode member 101 is also cut by a laser beam in some cases.

[0006]

As described above, when the outer peripheral portion of the movable electrode member 103 and the outer peripheral portion of the fixed electrode member 101 are cut with a laser beam, carbonized scum and various gases are generated during the cutting. In some cases, scum and various gases may enter the communication holes 115 provided in the outer peripheral portion of the panel. Therefore, this communication hole 115
In some cases, black spot-like adhesion or white turbidity occurred, and the appearance was sometimes poor. When the range of the dirt in the communication hole 115 is widened or the degree of dirt becomes remarkable, not only the commercial value of the touch panel 100 is lowered, but also in the extreme case, the function may be defective. This has led to a reduction in the production yield.

The present invention has been made in view of the above circumstances, and provides a high-quality transmissive touch panel in which no dirt or the like is generated in a communication hole provided in an outer peripheral portion of a panel. The purpose is to: Further, the present invention can prevent dirt and the like from being generated in the communication hole provided in the outer peripheral portion of the panel, and can prevent a reduction in commercial value and the occurrence of defects, thereby preventing a reduction in manufacturing yield. It is another object of the present invention to provide a method of manufacturing a transparent touch panel, which is capable of facilitating manufacturing and increasing manufacturing efficiency.

[0008]

In order to achieve the above object, the present invention takes the following measures. That is, the transmissive touch panel according to the present invention is based on the premise that the transmissive touch panel has a transmissive fixed electrode member and a transmissive and flexible member that is disposed opposite to the surface of the fixed electrode member through a non-contact gap. It has a movable electrode member and a bonding member interposed between the two electrode members in an arrangement surrounding the non-contact gap and maintaining a facing distance therebetween.

In this touch panel, a communication hole is provided at at least one position on the outer peripheral portion of the panel so as to open a non-contact gap between the two electrode members to the outside while traversing the bonding member. In the side of the outer peripheral portion of the panel where the communication hole is provided, at least a portion of the bonding member corresponding to the outer opening edge of the communication hole is formed as a position retracted inward of the panel. ing. By adopting such a configuration, even if cutting using a laser beam is performed in the process of manufacturing this touch panel, carbonized scum and various gases generated at the time of cutting are not allowed to flow from the outer opening edge of the communication hole. This occurs at a position that is substantially distant, so that it is possible to prevent entry into the communication hole.

[0010] The retreating of the outer side edge of the communication hole into the panel is at least necessary for the bonding member as described above. Further, as a specific example of the structure to be retracted, a notch-shaped concave portion may be formed at a substantial portion of the bonding member.
In this case, at least one (or both) of the fixed electrode member and the movable electrode member can be formed with a concave portion in accordance with the concave portion of the bonding member. Also, different from such a specific structure example, in the bonding member, the entire length of the side portion where the outer opening edge of the communication hole is provided is set to one of the fixed electrode member and the movable electrode member. It is also conceivable to match them over the entire length of the corresponding side, and then shift them in a step-like manner with respect to the entire length of the corresponding side of the other electrode member.

By the way, apart from the above-mentioned means of retracting the outer side edge of the communication hole into the panel, the communication hole itself provided in the bonding member is formed by bending a halfway portion in the direction of the passage. Such a structure can be adopted. With this structure, it is possible to prevent the carbonized scum and various gases generated at the time of cutting using a laser beam from entering the communication hole because it is difficult for the gas to enter the communication hole.
Such a halfway bending of the communication hole can be performed in combination with each of the above-described structures in which the outer side edge of the communication hole is retracted inward of the panel.

On the other hand, the method for manufacturing a transmissive touch panel according to the present invention basically includes a method in which a fixed electrode member having transparency and a movable electrode member having transparency and flexibility are opposed to each other. In order to form a non-contact gap between the facing surfaces of the two electrode members, a bonding member is interposed in an arrangement surrounding the non-contact gap, and the non-contact gap between the two electrode members is opened to the outside in at least one place of the bonding member. A communication hole is provided. Here, a plurality of fixed electrode members are prepared as fixed-side material sheets that can be measured (that is, large enough to cut out a plurality of fixed electrode members).

Similarly, the plurality of movable electrode members are prepared as movable-side material sheets from which the plurality of movable electrode members can be measured (ie, large enough to cut out the plurality of movable electrode members). Then, the both material sheets are bonded by providing a bonding member in a predetermined arrangement between the facing surfaces of the two material sheets. Then, individual touch panels are cut out by irradiating a laser beam from one or both of the fixed-side material sheet and the movable-side material sheet along a predetermined panel shape.

[0014] By adopting such a procedure, the working efficiency is firstly improved, thereby improving the productivity and reducing the manufacturing cost. This means that the fixed electrode member is formed on a film or plastic substrate,
It is particularly advantageous when the movable electrode member is formed using a film as a substrate. Further, at an appropriate stage at the latest until the laser beam is irradiated, at least one of the material sheet and the bonding member so as to correspond to the outer opening edge of the side where the communication hole is provided among the external shapes of the bonding member. And punched holes penetrating in the direction of their thickness.

By doing so, a recess corresponding to the predetermined distance including the outer opening edge of the communication hole is formed in the portion corresponding to the punched hole, and thus the cutting using the laser beam is performed. Even if carbonized scum or various gases are sometimes generated, it can be prevented that they enter the communication hole. In addition, it is also preferable to form the communication hole provided in the bonding member by bending the communication hole provided in the bonding member in the middle of the passage direction, as a combination with the provision of the punched hole as described above.

[0016]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 3 show a first embodiment of a touch panel 1 according to the present invention. The basic configuration of the touch panel 1 is substantially the same as the conventional one. That is, the touch panel 1 includes a fixed electrode member 2 having transparency, and a movable electrode member 4 having transparency and flexibility which is installed on the surface side of the fixed electrode member 2 through the non-contact gap 3. And a bonding member 5 interposed between the two electrode members 2 and 4 in an arrangement surrounding the non-contact gap 3 and maintaining a facing distance therebetween.

The fixed electrode member 2 is provided with electrodes 8 on two opposing sides in a plane directed to the movable electrode member 4, and has a movable electrode member 4 within a range sandwiched by the electrodes 8. Dot spacer 9 (FIG. 3) for limiting the deflection span (length in the surface direction) of the
) Are provided in a dotted pattern. In addition, the movable electrode member 4 includes, in a plane facing the fixed electrode member 2,
Electrodes 10 are provided on two opposite sides of the fixed electrode member 2 that do not coincide with the electrodes 8. The conductive wire 12 drawn from each electrode 8 of the fixed electrode member 2 and the movable electrode member 4
And a conducting wire 13 drawn from each of the electrodes 10 is connected to a controller (not shown) via a connector tail 14 provided toward the outer peripheral portion of the panel.

In the first embodiment, the fixed electrode member 2
The substrate 17 was formed by laminating a substrate 17 and a hard coat layer 18 covering the substrate 17, and the substrate 17 was formed of, for example, a polycarbonate film or plastic. The thickness is 1 mm to several mm.
On the other hand, the movable electrode member 4 is formed by laminating a substrate 20 and a hard coat layer 21 covering the substrate 20, and the substrate 20 is formed of, for example, a polyester film. The thickness is 50 to 300 μm.

The fixed electrode member 2 is not limited to the case where one hard coat layer 18 is provided on the substrate 17, and the hard electrode layer 2 has a laminated structure of a plurality of layers as shown in FIG. In some cases, a single structure in which the hard coat layer 18 is omitted may be employed. Also,
Although not shown, the same applies to the movable electrode member 4. The bonding member 5 is formed by a double-sided tape or the like. The point is that the bonding member 5 functions as an adhesive for bonding the fixed electrode member 2 and the movable electrode member 4 together with the fixed electrode member 2.
What is necessary is just to have a function as a spacer for securing the non-contact gap 3 between the opposing faces of the movable electrode member 4 and the movable electrode member 4. The material is not limited.

As shown in FIG. 2, this bonding member 5
A communication hole 23 for opening the non-contact gap 3 between the two electrode members 2 and 4 to the outside through the outer peripheral portion of the panel of the touch panel 1
Is provided. A notch 24 for connection is provided so as to correspond to the connector tail 14 where the conductive wire 12 of the fixed electrode member 2 and the conductive wire 13 of the movable electrode member 4 are converged. The above-mentioned communication hole 23 is provided with a concave portion 27 widened by a notch at the outer opening edge. Therefore, the outer opening edge of the communication hole 23 is located at a position deep in the recess 27, that is, substantially inward of the panel.

The movable electrode member 4 has a concave portion 28 which matches the concave portion 27 of the bonding member 5. Since the fixed electrode member 2, the movable electrode member 4, and the bonding member 5 are bonded to each other by the adhesive force of the bonding member 5, in the touch panel 1, the communication hole in the panel outer peripheral portion is formed. The recess 30 of the movable electrode member 4 and the recess 27 of the bonding member 5 are formed in the side portion 30 where the opening 23 is provided so as to cut off the outer opening edge of the communication hole 23. .

In the first embodiment, no recesses are formed in the fixed electrode member 2 so as to match the recesses 28 and 27 (that is, the matching portions of the recesses 28 and 27 extend in the thickness direction). However, the fixed electrode member 2 may be penetrated in the thickness direction by forming a recess in the fixed electrode member 2. In addition, as shown in FIG. 5, it is possible in some cases to provide a recess 27 only in the bonding member 5 and not to provide a recess in the fixed electrode member 2 and the movable electrode member 4.

Next, a manufacturing method according to the present invention will be described based on a case where the touch panel 1 of the first embodiment shown in FIGS. 1 to 3 is manufactured. As shown in FIG. 6, first, a fixed-side material sheet 40 capable of measuring a plurality of fixed electrode members 2.
And a movable-side material sheet 41 capable of measuring a plurality of movable electrode members 4 are prepared. Also, it is preferable that a plurality of the bonding members 5 are prepared in the form of a large bonding sheet 42 that can measure a plurality of the bonding members.

The number of fixed electrode members 2 in the fixed material sheet 40, the number of movable electrode members 4 in the movable material sheet 41, and
In FIG. 6, the measuring number of the bonding members 5 in 2 is four each, but is not limited at all. The fixed side material sheet 40 has an electrode 8 corresponding to the assigned position of the fixed electrode member 2 (indicated by a two-dot chain line).
And the conductive wire 12 are formed, and the movable material sheet 41 is formed.
First, the electrode 10 and the conductive wire 13 are formed corresponding to the assigned position of the movable electrode member 4 (indicated by a two-dot chain line).

The bonding sheet 42 has an opening 44 for forming the non-contact gap 3 corresponding to the assigned position (indicated by a two-dot chain line) of the bonding member 5, and the communication hole 23 and the connection hole. A notch 24 is formed. Further, a punching hole 45 for forming the concave portion 27 by cutting out each bonding member 5 is formed in the bonding sheet 42, and the movable side material sheet 41 is similarly formed in the punching hole 45. A punched hole 46 for forming the concave portion 28 by cutting out each movable electrode member 4 is formed.

When the preparation is completed, the fixed-side material sheet 40, the movable-side material sheet 41, and the bonded sheet 42 are moved to the fixed position of the fixed electrode member 2, the allocated position of the movable electrode member 4, The bonding members 5 are bonded together so that the assigned positions thereof match each other. Then, at the stage where the lamination is completed, each of the assigned positions is cut along a predetermined panel shape from one or both of the fixed-side material sheet 40 and the movable-side material sheet 41, so that a plurality of touch panels 1 are cut out. To

Here, the cutting employs a cutting method using a laser beam. The reason is as follows.
In the touch panel 1, it goes without saying that the transparency is raised as one of the things that are valued as its quality,
In addition, transparency in appearance is also regarded as important. That is, the fixed electrode member 2 and the movable electrode member 4 become cloudy and dirty,
If the touch panel 1 is damaged or the like, the touch panel 1 is regarded as a low-grade product or a defective product. In addition, it is widely known that among the materials used as the fixed electrode member 2 and the movable electrode member 4, those having high permeability tend to have high hardness and also have high brittleness in proportion thereto.

Therefore, if such a highly brittle fixed electrode member 2 or movable electrode member 4 is mechanically cut using, for example, a metal cutter blade, the fixed electrode member 2 (especially In the hard coat layer 18) or the movable electrode member 4 (especially the hard coat layer 21), a small chip may be generated at the cut edge, or micro cracks may extend inward of the panel. It is indispensable that the micro crack expands and spreads like a spider web. Further, since the fixed electrode member 2 has a thick volume, the cutter blade is significantly worn or chipped, which causes a problem in terms of work efficiency and cost in terms of replacement of the cutter blade.

In this case, an attempt to divide the contact of the cutter blade from both the fixed electrode member 2 and the movable electrode member 4 so as to reduce the cutting resistance as much as possible has been made to solve the respective problems. Although it leads to a certain degree of achievement, they have found that it is not a fundamental solution because the work involved in increasing the positional accuracy is complicated and complicated. In this regard, if the cutting method using a laser beam is adopted as described above, all the above-mentioned concerns when using a cutter blade can be eliminated, which is preferable.

In particular, in the cutting method using a laser beam, since a minute material fusion occurs simultaneously with the cutting at the cutting edge, the outer peripheral portion of the panel has a higher integrity and adhesion between layers, which is more preferable. Becomes Then, even during the cutting operation using the laser beam, even if carbonized scum and various gases are generated by burning of the used material (mainly the bonding member 5), the communication holes 23 are provided for the carbonized scum and various gases. At the side 30, the outer opening edge of the communication hole 23 is retracted inward of the panel, so that the outer hole 30 is generated at a position substantially distant from the outer opening edge. As a result, entry into the communication hole 23 is prevented.

Therefore, it is possible to prevent black spot-like adhesion and white turbidity from occurring in the communication hole 23. 7 and 8
Shows a second embodiment of the touch panel 1 according to the present invention. The touch panel 1 according to the second embodiment is different from the touch panel 1 according to the first embodiment in that the communication hole 23 formed in the bonding member 5 is bent in the middle in the direction of the passage. is there. In such a case, carbonized scum and various gases generated at the time of cutting using a laser beam are in a form in which straightness in the communication hole 23 is inhibited, and as a result, enter into the communication hole 23. Will be prevented.

In this case, the communication hole 23 may be bent in a variety of ways, including a lightning bolt as shown in the figure, and although not shown, the crank angle is bent at a right angle. Or a curved waveform is not particularly limited. As a method of manufacturing the touch panel 1 of the second embodiment, the method of manufacturing the touch panel 1 of the first embodiment includes only adding (or changing) a procedure of bending the passage shape of the communication hole 23 in a predetermined manner. , Basically the same.

As shown in FIG. 9, simultaneously with the structure in which the middle part of the communication hole 23 is bent, the structure in which the outer opening edge of the communication hole 23 is retracted inward of the panel as described in the first embodiment. The combined use is more effective. FIGS. 10 and 11 show a third example of the touch panel 1 according to the present invention.
1 shows an embodiment. In the touch panel 1 of the third embodiment, the communication hole 23 itself formed in the bonding member 5 has a straight passage direction and the communication hole 2
The concave portion 27 is not provided at the outer edge of the opening 3.

However, instead of these, at the side 30 where the communication hole 23 is provided, the bonding member 5 and the movable electrode member 4 are aligned over the entire length of the side, and then they are fixed. The electrode member 2 is shifted stepwise with respect to the entire length of the side portion (of course, the bonding member 5 side retreats inward of the panel). With such a structure, substantially the same operation and effect as in the first embodiment can be obtained. In the structure of the third embodiment, when the fixed electrode member 2 is made of glass, for example, a laser beam is irradiated from the movable electrode member 4 side, and the working depth is adjusted immediately before reaching the fixed electrode member 2. Method
Can be realized.

Needless to say, the structure of the third embodiment can be implemented by appropriately combining the structures described in the first and second embodiments.

[0036]

EXAMPLE With respect to the touch panel 1 of the first embodiment (FIGS. 1 to 3), the opening width dimension a and the depth dimension b of the concave portion 28 of the movable electrode member 4 and the concave portion 27 of the bonding member 5 are variously changed. An experiment was conducted to determine whether or not black spot-like adhesion or white turbidity occurred in the communication hole 23. The size of the touch panel 1 was 88.1 mm × 184.5 mm. Fixed electrode member 2
Used was made of polycarbonate and had a thickness of 2.0 mm.

The movable electrode member 4 was made of polycarbonate and had a thickness of 0.62 mm. The bonding member 5 is made of an acrylic resin and has a thickness of 0.09 m.
m. Laser beam output is 170 ± 10
W, the cutting speed was set to 40 mm / sec. At the time of this laser beam irradiation, a cutting gas was simultaneously jetted toward the cutting position. The injection pressure of this cutting gas was 3 kg / cm ² . Note that, for example, pressurized air may be used as the cutting gas.

Table 1 shows the types of changes in the opening width dimension a and the depth dimension b in the concave portion 28 of the movable electrode member 4 and the concave portion 27 of the bonding member 5 and the results of experiments.

[0039]

[Table 1]

As is apparent from Table 1, the movable electrode member 4 has the concave portion 28, and the bonding member 5 has the concave portion 27.
It has been confirmed that the effect of suppressing black spot-like adhesion and white turbidity to the communication hole 23 can be obtained by providing each of them. In this case, as the depth dimension b of the recesses 28 and 27 increases, the reliability of the effect also tends to increase. In particular, by setting the depth dimension b to 1.0 mm or more, it becomes practically preferable. It turned out that. By the way, the present invention is not limited to each of the above-described embodiments, and can be appropriately changed according to the embodiments.

For example, the number of communication holes 23 is not limited to one. The communication hole 23 is not limited to be an air hole, but in essence, refers to the communication between the non-contact gap 3 and the outside. In some cases, the connection notch 24 or the like However, it is only necessary to include the communication hole 23 in the category and to retreat the outer opening edge toward the inside of the panel. The present invention is not limited to a so-called FF type in which both the fixed electrode member 2 and the movable electrode member 4 are made of a film type, and a so-called FG type or GG type in which the fixed electrode member 2 is made of a glass type. It is feasible.

[0042]

As is apparent from the above description, in the transmissive touch panel according to the present invention, no dirt or the like is generated in the communication hole provided in the outer peripheral portion of the panel, and the touch panel is of high quality. Further, in the method for manufacturing a transparent touch panel according to the present invention, it is possible to prevent the occurrence of dirt and the like in the communication holes provided in the outer peripheral portion of the panel, and to prevent a reduction in commercial value and the occurrence of defects, As a result, a reduction in the production yield can be prevented, and simplification of the production and an increase in the production efficiency can be achieved.
