In order to protect the touch panel 10, a hard protective film 400 may be pasted on the film. In conjunction with FIG. 3 and FIG. 4, FIG. 3 is a schematic top view of the touchpad 10. On the upper and lower conductive layers 101 and 201, a plurality of interleaved electrodes 102 and 202 are formed respectively, and these electrodes 102 and 202 are connected to the controller 30 through a cable 20. Therefore, it will be driven by the controller 30 to provide a certain voltage or current to the conductive layers i〇 丨, 2〇 丨, where the upper electrode i will generate a linear voltage gradient in the X direction, and the lower electrode 20 A linear voltage gradient will be generated along the y direction. When the user presses the protective film, the upper conductive layer 101 near the pressing point will be connected to the lower conductive layer 201, which will generate a current or voltage change value. Therefore, the controller 30 That is, the (X, y) coordinate position at which the pressing point is located can be calculated. In the manufacturing process of the above-mentioned touch panel 10, it is conventionally known that after the thin film 100 is bonded to the substrate 200 and then the protective film 400 and the thin film are bonded together, the following problems often occur in the department: First, the rigid protective film 400 and the thin film 100 often cannot be completely adhered to each other, so air bubbles are generated and the yield is reduced. Secondly, it is known that after the film 100 is adhered to the substrate 200, the colloid of the two will maintain a distance between the upper and lower conductive layers 101 and 201 of about 100 ~ 200 / zm. The pitch is related to the driving force for bringing the upper and lower conductive layers into contact with each other when the user presses the touch panel. Therefore, if the phenomenon of incomplete adhesion between the protective film and the thin film can be effectively eliminated, the yield of the finished product can be improved, and if the distance between the thin film and the substrate can be shortened, the driving force can be reduced. [Content of the Invention] The touch detection action is more sensitive. Therefore, the object of the present invention is to provide a touch pad that improves the conventional manufacturing process and uses the driving force of the 5 p low touch pad and eliminates the defect that the protective film and the film are not fully adhered. Production method. This document addresses the shortcomings of the conventional resistive touch panel in the manufacturing process. Its technical characteristics are: A) The film of the touch panel is first heat-treated to remove the water content 10 and remove its tension. It is in a relatively dense state in the manufacturing process: this. (^ The biggest difference between the knife and the conventional process is that after the present invention is performed, only after the clothing is finished, the heat-treated film will swell by absorbing the K knife at normal temperature, and the protective film combined with it Because a large amount of dehumidification has not been used to privately rather than reabsorb the moisture in the air, after the two are combined together, 15 will cause a depression phenomenon due to the different expansion degrees, and the depression phenomenon can make the upper The gap of the lower conductive layer is narrowed, so that the white driving touch panel is not dehumidified, and the high driving force caused by the gap is too large. Therefore, the invention has the characteristics of low driving force and high sensitivity. 20 B ) Another improvement of this process is to combine the water-removed film with a protective film such as% or green, which can improve the conventional manufacturing process, and then combine the film with the substrate and then combine the protective film. The problem caused by the defective rate, for example, there will be a gap between the film and the substrate. When the protective film is combined, the stress will be uneven during the combined pressing process. Therefore, air bubbles are easily generated between the film and the protective film. and Heavy impact on manufacturing yield 6 1241514 C) Another process of the present invention is changed from the adhesion of thin film and protective film, which uses a low-viscosity and good fluidity material, which has the advantages of ... When the force is generated, the stress caused by Ku 6 5 can be used to disperse the non-positive part by the glue, which is less likely to cause the structure to be superb and shape, and the driving force is uneven; when the film and the protective film are caused When the fire is extremely hot and the T h fires are unevenly expanded, the plastic material with better fluidity can evenly disperse the internal shear stress caused by the mutual deformation and inconsistency, and can eliminate or equalize the force in the direction of the shear force without The driving force may vary depending on the uneven sentence. 10 [Implementation] Regarding the month of January; the other technical content, characteristics and effects are mentioned, and it will be clear in the following detailed description of one of the tea research schemes, private / soil ^ K. understand. Before ordering the steps of the present invention, as shown in FIG. 5 and FIG. A thin film of a first conductive layer u and a substrate 2 provided with a first conductive layer 21 are disposed. The material of the film 1 is made of poly-terephthalic acid 'and the substrate 2 can be glass, plastic or PET film. The first conductive sound 11a refers to indium-tin oxide (― •) or steel zinc oxide (indium-zinc-oxide) by vapor deposition methods such as evaporation and sputtering. (IZO), or indium-tin-zinc oxide (indium-tin / · "mtln_Zlnc-〇xide5 ITZO) is provided on the bottom surface 110 of the film 1 and the same as the 'top surface 210 on the substrate 2 is also provided with a method of the same manufacturing method as above Second conductive layer 21. 20 1241514 Figure 7 'The method of manufacturing a low driving force resistance touch panel according to the present invention is to perform heat treatment on the film 1 provided with the first conductive layer 11 as shown in step 701, so as to eliminate the film 1 Internal stress, in this embodiment, the internal stress and water vapor are removed by heat treatment after the film 1 and the first conductive layer 11 are pelletized and baked at a brewing degree between 80 ° C and 150 ° C. Since this observation is far lower than the melting point of the first conductive layer u, it will not cause the crystal system of the first conductive layer 11 to change. Next, as shown in step 702 and shown in FIG. 8, a protective film 3 is first bonded to the film that has completed step 701 and then other steps are performed. Here, the film 1 and the substrate 2 are bonded with Bai Zhi before bonding. The manufacturing process of the protective film 3 is different, and Lu Zhi's this step is to glue the protective film 3 stored in room temperature (00c ~ 300c, 20 ~ 85RH) in advance, and glue the film 1 in step 701. , 'On the non-conductive surface (top surface 112) of the film 1. In order to reduce the bubbles generated after the protective film 3 is adhered to the film i, the material of the film 3 is made of a material that is softer than the film 1, such as polyester (Myester) or polysacral acid (p〇). iyCarbonate, pc). In particular, the adhesive used for bonding between the film 3 and the film 1 should be selected with a low viscosity and a flowing fluid. It is better to use it when it helps the user to apply force on the protective film 3. The stress generated by the adhesive can disperse the non-positive force, so the protective film 3 is less likely to deform. In addition, the surface of the film 1 will undergo a hardening process to protect the surface of the film 1 from damage caused by improper application of force. Since the film 1 has been heat-treated first, the film 1 will be in a relative position relative to the protective film 3. The density is higher, so when step 702 is completed, 8 1241514 is mounted at room temperature, the film! Because it undergoes a dehumidification process in advance, it will absorb water and swell. On the other hand, because the protection 3 is not heated, its water swell capacity is small. Because of the asymmetric expansion, it makes the film work and protection. The middle part of the film 3 is slightly concave. … 5 As shown in step 703, a plurality of dot spacers 4 are set on the first conductive layer u or the second conductive layer u. The dot spacer 4 is used to prevent the first and second conductive layers 11 and 21 from contacting each other after the thin film 1 and the substrate 2 are bonded. 10. Forming the dot spacer 4 between the first and second conductive layers 1 丨 and 2ι is a technique that can be understood by those skilled in the art, and will not be repeated here. 15 20 Next, as shown in step 704 and referring to FIGS. 8 and 9, a first layer of the film i = the first layer of the electrical layer 11—a circuit layer 13 is provided, and a first layer of the second conductive layer 21 of the substrate 2 is provided.二 电路 层 23。 Two circuit layers 23. The circuit layers ΐ3 and μ are provided to provide the transmission of telecommunication numbers. In this embodiment, a four-wire touchpad is taken as an example. Therefore, the -circuit layer 13 ^ is used to provide a voltage gradient in the χ direction, so A first electrode body 1 ′ printed with silver wire and a first wire 132 connected to the two second-electrodes 131 should be formed on each of the left and right sides, wherein the first electrodes are respectively connected to the left and right of the first conductive layer u. The electrical connection on both sides is the same. The second circuit layer 23 is used to provide a voltage gradient in the y direction. Therefore, a second electrode 23b should be formed on both sides after w and a connection between the two -A lead 232, in which the second electrode 231 is electrically connected to two sides of the second conductive layer 21 on the rear side of the second conductive layer 21, and each of the electrodes and the leads are arranged in pairs and symmetrically, and each of the electrodes and the conductive layer are respectively The production of the related P-layer connections of the relevant circuit layer is a conventional technique, which is not repeated here. It should be noted that, if the helmet x Zhidou, „Xu, Poor + 疋 is a five-wire type, a six-wire type, or even an eight-wire type port, the number of electrodes, u ~ μ 酉 own position will be Somewhat awkward, because this is a 5 and is not the focus of the present invention, it will not be repeated here. 10, after 'as in step 7. 5, the step 7G2 has completed the protective substrate 3 of the soldier substrate 2 to obscure The body 5 is attached to each other. Here, an anisotropic conductive adhesive having a thickness of about #, a double-sided adhesive tape, or a printing frame (5 to 5 Am) can be used on the second circuit layer 23 of the substrate 2. A circuit layer =, attached to the adhesive layer, so that the first conductive layer 13 and the second conductive layer M are adjacent to each other. 'Because the binding film 1 is in a recessed state, The pitch is not the same, the shortest pitch is the shortest at the middle part. 15 After the film 1 and the substrate 2 are bonded to each other by the haze 5, it should be heated under pressure (approximately 3 (TC ~ 50. 155 seconds to 180 seconds, It is allowed to solidify and adhere. Finally, an optional step can be added, that is, after the touch pad is assembled, it can be heat-treated at a temperature of somot for about 1G ~ 3G minutes. Bake to remove moisture from the protective film 3. 20 Of course, when the film 丨 is attached to the substrate 2, a winding wire 6 needs to be placed between the film i and the substrate 2 so that the film i and the substrate After the 2 phases are laminated, the flexible cable 6 is electrically connected to the wires 13 2, 2 3 and 2 in an equal quantity and symmetrical manner, so that the controller (not shown) can be connected via the flexible cable 6 Supply voltage or current to the first electrode 3, 1 and the second electrode 1 to sense the user's touch action. In summary, the present invention is to heat treat the film to remove the internal stress 10 10 15 20 Figure 2 Is a cross-sectional view illustrating the structure of the touchpad; FIG. 3 is a schematic plan view illustrating the upper and lower electrodes of the touchpad 1241514 force and water vapor, and after bonding with the protective film 3 and then with the substrate 2 Lamination ', so when the film 1 is bonded to the protective film 3, the generation of bubbles after bonding can be reduced.' Better, because the protective film 3 is combined with the film 1 ', the film 1 after heat treatment, when back At room temperature, it will absorb water vapor again.
