[Prior Art] In recent years, the application of touch panels has become more and more widespread, and more and more touch panels have been installed on portable information devices. In a portable information device, such as a mobile phone, a small size game machine and the like, it is naturally desirable to have a lightweight and thin device and a structure capable of withstanding a drop collision without malfunction. Therefore, in place of the conventional touch panel based on the thin film glass structure, touch panels based on plastic materials such as FFP, FF, FP have become more widely used. On the other hand, in a mobile phone or a small game machine, a foldable type structure has been increasingly adopted. Many conventional machines employing a folding type structure have two screens, and the center-surface is used as a display screen and the other surface is used as an operation panel having a push button switch and a pointing device mounted thereon. When a touch panel is applied to such a device, the display screen is provided only on the one of the two surfaces. However, the most recent device 129956.doc 200903309 and its needs are attempting to increase the functionality of the display panel on both surfaces of the touch panel application. In such a device, one or two display screens have been performed. In order to apply the touch panel to a device having two , 贝 ,, as shown in FIG. 14 , two touch panels 70 , 80 are required. Therefore, there is a problem that two sets of flexible circuit bodies 71 and 81 are required for the two touch panels, and the structure of the touch panels is inevitably complicated. Therefore, the present invention has been researching

Although not directly related to the present invention, the present patent application No. H10-34G151 discloses a foldable type a la carte terminal having a plurality of switch sheets. In this ordering terminal, an adhesive ring is fixed to a substrate, and a plurality of switch sheets are bonded in the form of a bonded type book. Each of the switch sheets is composed of five resin sheets attached thereto. The switch sheets have a circuit body in which switches are formed. In a conventional resistive film type touch panel, an IT germanium film is formed as a conductive film. Since the IT0 film is hard and brittle, like a thin glass plate, there is a problem that when the sorghum film is bent by a small radius of curvature R, cracks and the conductive properties of the film are impaired. That is, there is a problem that the film is damaged due to stress applied to the curved portion of the tantalum film. For example, it has been confirmed that if the tantalum film is folded with a corner radius R 1.0, a change in resistance occurs after several and dozens of repeated folding and opening (see Fig. 9). SUMMARY OF THE INVENTION The problem described in the present invention is to provide a touch panel. The touch panel has excellent f-curve characteristics and high (four) long-term properties and can maintain reliable power for a long period of time. connection. In order to achieve the above object, in accordance with the aspect of the present invention, a touch-reverse 3 relative arrangement and a mutual adhesion of a fixed side substrate and an operation side substrate 'is formed on the fixed side substrate and on the operation side substrate, respectively. - a fixed side conductive film and an operation side conductive film, and can be detected between the end and the other end on any of the contact points 固定 on the fixed side conductive thin layer and the operation side conductive film by the 2D dimension Forming a bendable segment that can be bent 'and its two input operating zones are defined and formed on either side of the curved segment. According to the above configuration, since the curved segment defining the two-input operation region can be bent, even if one end portion of the touch panel is repeatedly bent in a direction in which the support point is toward or away from the other end of the touch panel, the heart is bent. When the touch panel is used, the stress concentration in the curved segment can be avoided. 1 The touch panel that integrally forms a unit can take two states, that is, an open state and an off state. In this way, it is possible to provide a touch panel which has excellent bending characteristics and high reliability and long-term reliability for electrical connection. In the touch panel described above, the solid-side conductive film and the operation-side conductive film may be formed of a conductive polymer. In the fixed-side conductive film and the operation-side conductive film, a conductive polymer is used instead of the IT film, and the 'Yanhai touch panel can be relaxed and folded when the curved segment is repeatedly supported as a support point. The stress of the segment and the damage to the conductive film are reduced, so as to achieve a significant improvement in the durability of the touch panel of the 129956.doc 200903309. In the touch panel described above, it is also possible to use the fixed side conductive film and the -conductive polymer as the operation side conductive: film. Although the IT film is a hard and brittle material, the stencil or the like removes the enamel film from the curved segment, and the slamming segment can be used as a support point to bend the touch. panel. b 5 In the touch panel described above, it is also possible to form a fixed side substrate from a broken glass and to divide the touch panel into two parts in a curved section and to form a transparent film integrally in the unit. Operate the side substrate. Since the two-input operation area is based on glass, it is possible to provide a touch panel that can be folded without the strength (flexibility) of the A & Touch panel. In the touch panel described above, it is also possible to form an insulating layer in the curved segment. With such a structure, the occurrence of a short break in the curved section can be eliminated. A plurality of dot spacers in the touch panel described above having a narrower spacing than the dot spacer formed in the two operation regions can be formed in the curved segments. The uniformity of the gap between the opposing conductive films having such a structure can be maintained. In the touch panel described above, a tone correction film can be formed for correcting the blue color of the conductive polymer material. Such a tone correction film can accurately reproduce the color of a liquid crystal display or the like and thus obtain a south quality image. In the touch panel described above, the tone correction film may be a hard coat layer containing a yellow pigment as a color correction element. Having such a hard film 129956.doc 200903309 layer 'is effectively weakened the blue color of the conductive polymer material. In the touch panel described above, an external circuit configuration can be electrically connected to the fixed side conductive film and the operation side conductive film at a position via a predetermined line pattern. Since an external circuit configuration such as an FPC is connected in one place, the structure of the touch panel can be simplified. The touch panel as described above can be applied to a folding type information device having two folded liquid crystal regions so that the two input operation regions are attached to the two liquid crystal regions. The touch panel can also be applied to an electronic paper that displays the material by applying a magnetic field or an electric field. Since the touch panel can be formed on the liquid crystal area of a folding type information device or on an electronic paper, the operability of information input to the information device can be improved, and the application range of the touch panel can be expanded. The above and other objects, features and advantages of the present invention will become apparent from the <RTIgt; [Embodiment] Now, the present invention will be described in detail with reference to the accompanying drawings. 1 is a view of a touch panel in accordance with an embodiment of the present invention. As shown in FIG. 1 , a resistive film type touch panel 1A of this embodiment includes: a fixed side substrate (film) u, the fixed side substrate is a lower substrate adjacent to a liquid crystal screen; a side substrate (film) 12 - a substrate to be pressed by a finger, a stroke or the like, disposed opposite the fixed side substrate n; and an FPC connector 13 electrically interconnecting the two substrates U, 12 to the main body of the device ° The touch panel 1G is applied to a two-liquid crystal screen area - 129956.doc -10- 200903309 folding type information device 5 (Fig. 4)' and integrally formed in a layer having an input operation area 14 , 15 and a curved region (bending section) 16 between the two-wheel operating area (4). Therefore, the -operation region 15 is adapted to be bent with the curved region 16 as a support point. The touch panel 10 of this embodiment will be described in detail below. The two substrates 11, 12 have substantially the same structure 'except that the dot spacers 18 are formed on the solid side of the substrate 11. The two substrates 1 1 and 12 are attached to each other inside the frame portion with a gap (relative pitch) of about 100 μm. The dot spacers 18 are formed of epoxy resin or the like, and are provided at a prescribed pitch of 40 μm in diameter and several micrometers in height. The spacing between two adjacent dot spacers 18 is wider in the two input operating regions 14, 15 and is narrower in the curved region 16, such as a dot spacer in an input operating region 14, 15 The distance between 1 8 can be 23⁄4 meters and the distance between the dot spacers 18 in the curved region 16 can be millimeters. The uniformity of the gap between the opposing conductive films (resistive film sheets) 20, 21 by the dot spacers 8 formed at a narrow pitch in the curved region 丨6 can be maintained. Moreover, as shown in Fig. 2, the edge film 22 formed in the curved region 16 cooperates with the provided narrower pitch spacers 8 to prevent short-path occurrence in the curved region 16. 12 has a base material 45, 46 which is formed of biaxially widened polyethylene terephthalate (PET) having a thickness of 100 to 200 μm, respectively, and H has a thickness of 1,75 μm.

According to this embodiment, the durability of the touch panel with respect to bending is very high, and it has been experimentally confirmed that there is no crack and change in resistance after repeated bending of the corner radius of 1 mm. The system is very small (Figure 9). On the contrary, for the conventional touch panel, even in the initial stage of repeated bending, the change in resistance is very large, and it has been found that it cannot (re) repeat the f-curve. When the screen of the touch panel 1G is performed by the writer, the stress concentration of the conductive polymer is moderated, and the durability of the touch panel 10 with respect to the writing operation is also improved by the elasticity of the conductive film itself. . The bending test will be described later. As shown in Figures 3A and 3B, the two substrates are 丨! The frame portion of 12 is compared with the input operation area of the touch panel 1 系 is a non-input area, and a pair of electrodes 24, 25, 27 are respectively provided on one of the opposite edges of each of the substrates 11, 12, so that two When the substrates 丨丨, 12 are combined, they form a frame-like shape. Each pair of electrodes 24-27 can be formed from silver and a polymer resin. For each pair of electrodes 24-24, the coordinates of the input point and the gamma-coordinate are detected via the Fpc connector 13 once by means of a finger or an input. In the frame portion of the two substrates 11, 12, a pair of electrodes 24_27 1 are formed with an insulating pattern 28, 29 or a pattern of silver and a polymer resin 129956.doc -13 - 200903309 line pattern 30, 31 (for interconnecting a flexible circuit board to an electrode) can be formed using an acrylic resin adhesive. The substrates 11 and 12 are attached to each other using the double-sided tape 33. The formed double-sided tape 33 (Fig. 1) corresponds to the frame portion of the substrates u, 12 in shape and size. The double-sided tape 33 has an adhesive layer on both sides of an insulating plastic film so that it can also be used as an insulating material for the electrode 24_27 in the form of a frame. The thickness of the double-faced rubber 33 can vary depending on the application, and a double-sided tape having a thickness of, for example, 3. micron can be used. The FPC connector 13 as shown in Fig. 2 is molded by resin and connected to the frame portion around the input operation region 14 by pressure bonding. Connector I] consists of a housing and a 4-pole internal terminal (not shown). An FPC (Flexible Printed Circuit) 34 for signals is connected to one end of each terminal, and a wiring pattern formed in the two substrates 11, 12 is connected to the other end of the terminal. FIG. 4 illustrates a foldable type information device 5 having a two-folded liquid crystal region and a touch panel 1 of the present embodiment mounted thereon. The touch panel 1 y y input operation areas 14, 15 are attached to the liquid crystal area of the information device 50. Since the input operation is performed on the second screen, the operation of inputting information to the information device 5 can be improved and applied to other uses becomes possible. Next, a bending test on a conventional film having an ITO film and on a film having the organic conductive polymer of the present invention will be described. Figure 5 is a schematic illustration of a test film 6 for bending test. The test film 60 has a prescribed thickness and a prescribed length, and has a pair of electrodes 61, 62 for measuring the resistance provided at the two longitudinal ends. 6A-6C are cross-sectional views along line a_A of the test film 60 of Fig. 5. Figure 129956.doc -14- 200903309 6A shows a polymer film 60a of the present invention having an organic conductive polymer 2〇 on the lower side, and a conventional tantalum film 60b having an IT〇 film 43 on the lower side, FIG. 6C illustrates a modified conventional ITO film 60c having a tantalum film 43 on the lower side as shown in FIG. The individual test films 60a-60c have a layered structure of a base material 45 formed of a PET resin, a hard coat layer 42 coated on the upper surface of the PET resin 45, and coated on the lower side of the PET resin 45. A transparent conductive layer 2, 43 is composed. In FIG. 6A, the thickness a2 of the PET resin 45 is set to 120-200 μm, the thickness a1 of the hard coat layer 42 is set to 3-4 μm', and the thickness a3 of the organic conductive polymer 2 is set to 100-200. Micron. In Fig. 6B, the thickness b2 of the PET resin 45 is set to 100 - 200 μm, the thickness bl of the hard coat layer 42 is set to 3-4 μm, and the thickness b3 of the ITO film 43 is set to 5 - 10 μm. In Fig. 6C, the PET resin 45 has a sandwich structure in which the PET resin 45 & in the upper layer and the pET resin 45b are adhered to each other by the soft adhesive 44 in the lower layer. By providing P E T tree in the second layer, the 4 5 ′ improved film 6 0 c is about the longevity of bending. In Fig. 6c, the thickness c2 of the upper PET resin 45 is set to 100-200 μm, the thickness c3 of the rice-filling agent 44 is set to several micrometers, and the thickness c4 of the lower layer of the pet resin 45 is set to about 25 μm. The thickness cl of the hard coat layer 42 is set to 3-4 μm and the thickness C5 of the ITO film is set to 5-1 〇 micrometer. In Fig. 7, 'the test film 60a-60c is repeatedly bent using the end of one of the jigs 63 for bending test as a bending point. In this test, mechanical stress is applied to the test films 6a-60c by folding and opening the test film 60a-60c as a bending point, and detecting a pair of electrodes 62 in the folded state, A change in resistance between 62. 129956.doc -15- 200903309 In Fig. 8, the relationship between the corner radius R of the end of the jig 63 and the resistance measured when the test films 60a-60c are bent to this corner radius R mm is shown. The conventional ITO film 60b has very poor bending properties and has exhibited a resistance change when the corner radius R is 8 mm. The improved IT 〇 film showed no change in resistance when the corner radius R was 8 mm, but the resistance changed when the corner half was R 2 metre, and the crack occurred in the curved section. On the other hand, the resistance of the polymer film 60a was not changed when the corner radius was 丨 mm, and the curved segment was found to flexibly follow the folding and opening operation. This property of the polymer film 60a is highly advantageous when it is used in a touch panel in which mechanical stress is applied to the film by direct doting and one-shot writing of a tip. In Fig. 9, the relationship between the number of repeated bendings and the resistivity measured when the test film 6 is 6 (where the bending is performed) is shown, wherein the test film 6〇a_6〇c is bent at the end of the jig 63. The radius r is 2 〇. At the first bend, the ITO film 60b exhibits a change in electrical resistance, and a large resistance change due to further bending. At the first bend, the improved IT〇 film 6〇c is in terms of resistance; There is also a change in appearance, but after repeated, after bending for 1 turn, the resistance begins to change 'and a large change in resistance due to repeated bending of 100 or more times. On the other hand, the polymer film 60a is being No change in resistance was shown after repeated bending for 100 times and only slight change was observed in resistance after repeated bending for 10,000 times. Thus 'the organic conductive film 20 has the flexibility of the polymer material in the polymer film 60a' and polymerization has been found The material has good compatibility with the PET matrix material 45, and is caused by the destruction of the structure after repeated bending. 129956.doc 16 200903309 Plugging, such as the degradation of conductivity Conversely, conventional ιτ〇 film _, 6Ge (where ΙΤ (10) film 43 is formed in a vacuum by a spray coating and thus a thin and fragile glazed film on the ΡΕΤ matrix material 45 has been found to be curved Poor durability. Next, a variation of the touch panel will be described with reference to Figures 10-13. In the drawings, the dimensions in the thickness direction are exaggerated to promote understanding of the structure. In Figures 10-12, The touch correction panel 4GA_4GCe which does not have a tone correction film 41 for correcting the blue color of the conductive polymer is formed on the outermost layer of the substrates 11, 12 as a hard coat layer 42 containing a yellow pigment. For example, yellow or azo-based yellow pigment is recorded. The thickness of the hard coat layer 42 which is usually formed is several micrometers to increase the surface hardness or abrasion resistance of the substrates u, 12. The color correction film 41 of the present invention is one in A hard coat layer 42 to which a color correction function is added. In Fig. 10, an embodiment of the present invention is illustrated, wherein the color tone correction film 41 is provided on both the fixed side substrate and the side substrate. On the 11th and 12th, the hard coat layers 41 and 42 are composed of two layers, that is, the upper layer and the lower layer, the lower layer functions as a tone correction film and the upper layer is generally hard coated 42 and has no chromatic aberration correction function. The correction film 4 丨 weakens the blue tint of the touch panel 40A so that the discomfort of the touch panel can be reduced and the quality of the touch panel can be improved. In the embodiment, a tone correction film 41 is provided only on the operation side substrate 12. On the operation side substrate 12, the hard coat layers 41, 42 are composed of two layers, that is, the upper layer and the lower layer, and the lower layer serves as a lower layer. Hue correction thin film 129956.doc -17· 200903309 The film 41 functions and the upper layer is a general hard coat layer 42 and has no chromatic aberration correction function, as shown in FIG. It has been confirmed that it is also effective to provide the tone correction film 41 only on the operation side substrate 12.

As shown in FIG. 11, the conductive film on the fixed side substrate u is an ITO film 43 and on the operation side. The conductive film on the substrate 12 is a conductive polymer. In the touch panel 40C, the ITO film in the curved region 16 on the fixed side substrate 11 is removed, and the touch panel 4c can be bent as a corner of the curved region 16. In this variation, the writing durability of the touch panel 4c is not impaired due to the conductive polymer coated on the operation side substrate 12. FIG. 13 illustrates a touch panel without a tone correction film. In the touch panel 40D, a conductive polymer is formed on the fixed substrate, and a 1T film 43 is formed on the operation side substrate. 12 on. Therefore, unlike the touch panels 10, 4A, 4B, 4〇c described above, the touch panel cannot be bent with the curved region 16 as a support point. The touch panel is advantageously advantageous because the ITO film 43 on the fixed side substrate 11 is replaced by a conductive poly-α, the durability of the touch panel 4D can be improved, and at the same time, the ITO film 43 is light yellow. The adjustment can be used to correct the blue hue of the conductive polymer. As has been explained above, for the touch panel of the present embodiment, the curved region 16 defining the two input operation regions 14, 15 can be freely bent, and therefore, when the touch panel is in a curved region, the bamboo helmet ± ^ 3 〇 When it is a support point and repeatedly bends 129956.doc -18-200903309 at one end of the touch panel toward or away from the other end of the touch p-diameter panel, stress concentration is prevented from being concentrated in the curved region 16. Therefore, it is possible to provide a touch panel capable of being repeatedly bent and having high durability and excellent electrical connection reliability. The present invention is by no means limited to the embodiments described above, but may be practiced in various modifications without departing from the scope of the invention. Although in the present embodiment, • PET 45, 46 is applied to the substrates 11, 12, it is also possible to use, for example, a lime-lime glass having a thickness of WU mm as a fixed-side substrate ('/material. In this case) By dividing the portion of the curved region 16 of the corresponding base material into two parts, the strength of the touch panel can be increased without impairing the bending ability of the touch panel.
