Description of the Invention: [Technical Field] The present invention relates to a touch panel, and more particularly to a touch that can improve process convenience panel. [Prior Art] With the development of flat panel display technology, the display effect of the flat panel display has been greatly improved. Moreover, due to the advancement of process technology, the cost of driving the flat f display has decreased, making the flat panel display popular among consumers in the market. In order to improve the convenience of use, in recent years, the industry has integrated touch panels into flat-panel displays and applied them to various electronic devices; for example, in mobile phones, users can click on the screen directly on the panel. To carry out various operations, thereby providing a more convenient and user-friendly operation mode. Among the various types of touch panels, capacitive touch panels are the subject of recent developments by manufacturers. Capacitive touch panels are widely used in electronic products because of their multi-touch, high transparency, long life and suitability in harsh environments. The structure of the capacitive touch panel mainly includes a transparent substrate having a first conductive film on the upper surface thereof and chemical or laser etching to meet the requirements of the product, and the lower surface can be designed according to different applications. Conductive film. In general, in order to increase the aesthetic value and commercial value of the touch panel, an adhesive layer (such as optical glue, polymer glue, double-sided tape) may be coated or attached on the surface of the transparent substrate, and The flexible diaphragms are joined to each other, so the shape and size of the touch panel and the flexible diaphragm must be the same. 5 201001259 I νΎ ~TII Γ~\. In the choice of materials, generally the transparent substrate is polycarbonate plate or glass. The transparent substrate made of polycarbonate is easy to process, but its light transmittance is not good; glass The transparent substrate of the material has good light transmittance, but the processing process is not easy. Moreover, both of them are likely to damage the first conductive film or the second conductive film on the surface during processing, thereby reducing the yield of the production process. In addition, when the touch panel is applied to electronic devices of different specifications and sizes, it is necessary to change the position at which the through holes are punched out on the transparent substrate, and correspondingly change the size of the transparent substrate. This is quite costly and reduces the efficiency of the process f'k.

The lining 180 is made, for example, of polybrothene or polyacetate, and (iv) flexible film 201001259 The adhesive layer 120 on the surface of the sheet 110 is disposed on the flexible film ι10. In the present embodiment, the lining 180 is, for example, adjacent to the transparent substrate 150. Hereinafter, the transparent substrate 150 and the lining sheet 180 will be described as an example. Referring to Fig. 3, there is shown a sound-receiving diagram of the flexible film, the transparent substrate, and the lining in Fig. 2. A transparent substrate 15 and a lining 180 are correspondingly disposed on the same side of the flexible cymbal 110, and are preferably one side of the flexible diaphragm 11 相反 opposite to the opaque coating ii 〇 b . In addition, the flexible film 11 〇 has, for example, a plurality of first through holes 110a' disposed on the flexible film u 〇 ' at the lining 180; correspondingly, the lining 180 has At least - the second through hole 180a corresponds to the number, shape and position of the first through holes u 〇 a. In practical applications, when the touch panel 1 is applied to, for example, a mobile phone, the first through hole 11a and the second through hole 18A have functions of exposing components such as a handset or a video camera of the mobile phone. . In the process of the touch panel 100, only the first through hole 11〇a and the second through hole 18〇a are cut out on the flexible film 11〇 and the lining 180 of the plastic material. The size, shape, and goodness of the conductive film disposed on the transparent substrate 15 are reduced by the method, and the process cost is reduced and the process efficiency is improved. In the touch panel 1 according to the preferred embodiment of the present invention, the lining 180 is exemplified by the configuration of the adjacent transparent substrate 150. However, the arrangement of the slab 180 and the transparent substrate 150 is not limited thereto. The system can be changed according to the design requirements of different products. For example, the lining 18 can also be disposed around the transparent substrate 150. Please refer to Fig. 4, which is a schematic view showing the arrangement of the dry lining around the transparent substrate. The transparent substrate 15 and the reticle 180' are disposed on the same side of the flexible film 11', and the lining 18 〇 is wrapped around the transparent substrate 150 by 9 201001259. In addition, the flexible film 110, the light-transmissive region U0c whose surface is not covered by the opaque coating 110b', substantially corresponds to the transparent substrate 150 for exposing at least a portion of the transparent substrate 15A. The flexible film 110' has at least one first through hole 〇a, 'located on the flexible film 〇, corresponding to a portion outside the light transmitting portion 〇c'. The lining 180 has at least one second through hole 180a'' corresponding to the number, shape and position of the first through hole 110a. That is to say, it is not necessary to cut the through holes on the transparent substrate 15 in the manufacturing process. Further, please refer to FIG. 3 and FIG. 4 at the same time, under the condition that the same transparent substrate 15 应用 is applied, only the area of the flexible films 110 and 110 ′, the lining 180 and the lining 180 are required to be changed correspondingly. 180, the configuration manner and the range of the light-transmitting regions 110c and 110c, so that the silver ep〇xy (not shown) disposed on the upper surface and the lower surface of the transparent substrate 15 is not exposed. The light-transmissive areas 〇c and 110c' can be touched in different electronic devices of different specifications. In this way, it is not necessary to change the cutting shape of the anti-transparent panel 150, and it is not necessary to cut the CJ through hole on the transparent substrate 15〇, and the first conductive film 130 or the second conductive film on the surface of the transparent substrate 可以5〇 can be avoided. No (pictured in Figure 2) is a problem of damage. The step of forming the first conductive film m and the second conductive film 170 (e.g., miscellaneous or vapor deposition) can be performed on a large-sized transparent substrate before cutting, which improves the efficiency of the process. In the touch panel of the preferred embodiment of the present invention, the first through hole on the flexible film and the second through hole on the lining expose the components under the touch panel, and the cutting is not required for the transparent substrate. It simplifies process complexity and improves process efficiency and yield. In addition, by changing the size of the 201001259 and the configuration of the lining, the touch panel can be applied to different specifications, which further increases the flexibility of the touch panel and saves man-hours and costs. In the above, the present invention has been disclosed in the preferred embodiments, and is not intended to limit the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention. Therefore, the scope of the invention is defined by the scope of the appended claims. 11 201001259 [Simple description of the drawing] The first picture depicts the secret picture of the present invention (4) the diagram of the difficult panel of the actual closing; f 2 shows the perspective view of the touch panel in the second drawing; In the figure, the flexible film y - stand-up film, transparent substrate and lining are not considered; and the figure 4 shows the arrangement of the moon around the transparent substrate [main symbol description] 100 : touch panel 110, 110': flexible film ll〇a, ll〇a': first through hole 〇b, 110b': opaque layer 110c, 1 l〇c': light transmitting area 120 · adhesive layer 130 : First conductive film 150 : Transparent substrate 170 : Second conductive film 180 , 180 ′ : linings 180 a , 180 a ′ : second through hole 12
