Description of the Invention: [Technical Field of the Invention] The present invention relates to a view-capacity paste control panel, a copper touch panel, and a method of manufacturing the same. [Prior Art] A capacitive touch panel is attached to the display for the user to follow the indication of displaying the 11 screens. Click on the touch panel and drag to input the command. A conventional capacitive touch panel is shown in FIG. 1. The sensing layer 12 includes a subtractive inductor disposed on the upper surface (4) of the substrate M by a photoelectric process, and the shield layer 16 is deposited on the lower surface 144 of the substrate I4. Insulate the noise interference between the sensing layer 12 and the lower display or circuit component (wire). The soft_circuit printed circuit assembly (FpCa) i8 connects the sensor to process the sensed signal. Then, as shown in Figure 2 The adhesive inner layer 104 is bonded to the sensing layer I2 and the flexible printed circuit control 18 to form a capacitive touch panel 22. The protective layer 10 is used to protect the inductors in the sensing layer 12 and is operated by the user on the operating surface 102. The substrate 14 is used to provide the sensing layer 12 and the shielding layer 16. The protective layer 1 and the substrate 14 in the conventional capacitive touch panel are made of a hard glass material. Since both the protective layer 1 and the substrate 14 are hard plates, it is disadvantageous for the adhesive bonding. Common problems such as occurrence of bubbles are difficult to remove. The hard board bonding process has high construction difficulty, low yield, and high cost. Therefore, the present invention provides a capacitive touch panel and a manufacturing method thereof, which avoids the hard board attaching process, lowers the cost of 201107825 and improves the yield. . SUMMARY OF THE INVENTION The object of the invention is to provide a capacitive touch panel. The object of the present invention is to provide a method of manufacturing a capacitive touch panel. According to the present invention, a type of electric valley touch panel includes a protective layer having an operation surface and an inner surface, the sensing layer is disposed on an inner surface of the protective layer, and the adhesive medium layer adheres the sensing layer to the soft board coated with the conductive layer. fit. According to the present invention, a method for manufacturing an electric valley type touch panel includes providing a protective layer, disposing a sensing layer on an inner surface of the protective layer, providing a soft board plated with a conductive layer, and bonding the soft board and the induction| A bonding medium layer is formed between the soft board and the sensing layer. In the present invention - the embodiment is implemented by a transparent insulating film with IT0 or Zn. In an embodiment of the invention, the first direction sensor, the wire and the second direction sensor are disposed in the same plane, and the first direction sensors are connected to the wires, and the second direction sensors are spanned. The first direction sensor or the conductive bridges of the wires are connected to realize a thinned sensing layer. [Embodiment] FIG. 3 and FIG. 4 are schematic diagrams showing a first embodiment of a capacitive touch panel of the present invention. The upper surface of the protective layer 30 is an operation surface for a user to operate, and the sensing layer 32 is protected by a photoelectric process. The inner surface of the layer 30 3 〇 4 'conductive layer 4 [S1 4 201107825 is plated on the soft board 34, and the flexible printed circuit board 36 is connected to the sensing layer 32 for processing the sensed signal. In this embodiment, the conductive layer 344 For indium tin oxide (ITO), it is plated on the soft board 34 by means of sputtering, coating or printing, and then as shown in FIG. 4, the sensing layer is bonded by the adhesive medium layer 38. 32 and the flexible printed circuit board 36 are adhesively attached to the flexible board 34. The conductive layer 344 on the flexible board 34 provides a noise shielding function for the sensing layer 32. In other embodiments, conductive layer 344 can be implemented with zinc oxide (ZnO). In different embodiments, a layer of anti-reflective or glare material may be formed on the soft board or the protective layer to provide the touch panel with anti-reflection or glare-proof characteristics to provide better visual effects. Antireflection films are mostly made of low refractive index SiOx (n=1.46) or polymer resin (n=1 42_丨46). Recently, due to the diversified development of materials, heterogeneous materials in which SiOx and resin are mixed are often used. used. The deposition position of the anti-reflection film may have different anti-reflection effects depending on the operation surface 3〇2, the inner surface 304 in contact with the finger, or on the soft board 34 depending on the deposition position. The anti-glare will be an organic lion hybrid particle, which can be an organic or inorganic material that effectively diffuses the incident light source. Therefore, the anti-glare film should be deposited on the outermost surface, that is, the operation surface 3G2. The anti-reflective film and the anti-glare film can be used at the same time. Appropriate matching can not only increase the brightness of the backlight, but also reduce the reflection of the external light source, improving visibility and clarity. In the present embodiment, the flexible board 34 is a transparent insulating film having a certain thickness separating the sensing layer 32 and the conductive layer 344, so that the capacitance value formed therebetween is reduced to avoid the shadow axis surface 32. The age-appropriate age can be such that the plate 34 is gradually crimped to the sensing layer %, and this application requires a low 'good yield' cost reduction. Wherein, the adhesive medium layer 38 can be two

Referring to FIG. 2 , the sensing layer 12 and the shielding layer 16 of the conventional touch panel 20 are disposed on the upper and lower surfaces of the substrate 14 , so that the supporting power required by the substrate η is high, and the sensing layer 32 of the present invention is instead disposed on the protective layer 30 . The inner surface reduces the support required for the soft board 34. 5 is a top view of a second embodiment of a capacitive touch panel according to the present invention, the sensing layer disposed under the protective layer 50 includes a first direction trace 52 and a second direction trace 54, and FIG. 6 is a broken line in FIG.

Since the first direction sensor 522 and the second direction sensor 542 are both disposed on the same plane, the sensing layer of this embodiment can be thinner than the conventional two-layer architecture. After the sensing layer 56 is disposed, the dielectric layer 64 is formed thereon, and the sensing layer 56 and the flexible printed circuit board 36 are adhered to the flexible board 34 coated with the conductive layer 344 by the adhesive medium layer 38. 7 is a cross-sectional view of a third embodiment of the present invention.
