Description of the Invention: [Technical Field] [0001] The present invention relates to a method for manufacturing a flexible touch panel, and more particularly to a flexible touch panel having a low manufacturing cost and a simple manufacturing method. Manufacturing Method 0 [Previous Technical Standards] [0002] 〇 With the development of technology, the design of electronic products has gradually become more mainstream with the close interaction between human and computer and the simple operation interface. The touch panel is attached to the outside of the flat panel display to match the flat display display image as an intuitive and easy to use interface. The user can directly display the screen on the screen by finger contact or stylus. Like the text to achieve the purpose of losing Yuanxun and manipulating the product. [0003] With the development of flat-panel displays in a large area, the display of lighter, thinner, or even flexible, portable displays has become the main goal. Nowadays, it has become a display development to replace hard substrates with flexible substrates. The trend is that touch panels have the same trend. [0004] In order to meet the requirements of the flexible substrate introduction process, the flexible substrate is usually introduced into a conventional device by using a rigid substrate as a support, and then various processes are performed on the flexible substrate, for example, in a flexible manner. A film forming process or a thin film transistor is performed on the substrate. In general, conventional flexible touch panels are typically fabricated using a temporary adhesive that bonds the flexible substrate to a rigid substrate and physically or chemically strips the flexible substrate. However, the viscosity of the temporary adhesive is not easy to control, and the thermal stability is not good, and it is easy to cause a problem of poor adhesion or difficulty in peeling. 099104570 Form No. A0101 Page 3 of 17 0992008605-0 201128476 [0005] [0006 [0007] [0008] 099104570. Further, if the flexible substrate is chemically peeled off, the corrosion resistance of the substrate itself needs to be considered. In another method, the flexible substrate is attached to the hard substrate by an adhesive layer, and after the subsequent process is applied, the germanium is removed by high-temperature laser or light debonding. The adhesive layer is adhered, and the finished flexible touch panel is separated from the rigid substrate. However, equipment that is bonded by laser or illumination is expensive, time consuming, and limited in effect, and has a limited process speed and high cost. Moreover, if the adhesive layer is too viscous, the flexible substrate is removed from the rigid substrate. During the removal process, it may also damage the precision components on the flexible substrate. SUMMARY OF THE INVENTION In view of the above, an object of the present invention is to solve the above problems, and to provide a method of manufacturing a flexible touch panel which is easy to manufacture and which does not leave a residual glue. In order to achieve the foregoing objective, the present invention provides a method for manufacturing a flexible touch panel by attaching a partial region of a flexible polymer layer of a touch panel to a rigid substrate by an adhesive layer; The polymer layer forms an easy-disengagement interface with the rigid substrate. The manufacturing method of the flexible touch panel of the present invention comprises: preparing a hard substrate; forming a discontinuous adhesive layer on the hard substrate; forming a flexible polymer layer on the adhesive layer and the hard substrate The region of the flexible polymer layer contacting the rigid substrate is defined as a patterned region; a patterned region of the sensing layer on the flexible polymer layer is formed, the patterned region is cut, and the The flexible polymer layer of the sensing layer is detached from the rigid substrate. In the above embodiment, a protective layer may be further formed on the sensing layer. Form No. A0101 Page 4 of 17 201128476 [0009] With the present invention, when the touch panel is detached from the rigid substrate, it is easy to peel off without using expensive laser or illumination equipment, and the process is simple and no residue remains. It can solve the problem that the conventional touch panel is not easy to remove from the hard substrate. The detailed technical content and preferred embodiments of the present invention are described in conjunction with the drawings. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT [0010] The detailed description and technical contents of the present invention are described below with reference to the drawings, but the drawings and the component numbers are for illustrative purposes only and do not represent actual dimensions. And the proportions; and for the sake of simplicity and ease of understanding of the drawings, some of the drawings also omit the drawing of the conventional elements without affecting the implementation and understanding of the present invention. [0011] Please refer to "FIG. 1" to "Bob 7" for a schematic flow chart of a manufacturing method according to an embodiment of the present invention, and a top view corresponding to the above "FIG. 1-1" to "Bob 5". Figure 2-1" to "Figure 2-5". The invention provides a manufacturing method of the flexible touch panel 1 , the steps of which include: “00121 1 by 詈 石 石 f Π Π Π Π Π Π Π Π Π Π Π Π Π Π Π Π Π Π Π Π Π Π Π Π Π Π Π Π Π Π Π Π Π Π Π Π Π Π Π Π a discontinuous adhesive layer 11 on the rigid substrate 10; 3. a flexible polymer layer 12 is formed on the adhesive layer 11 and the hard substrate 10; the flexible polymer layer 12 contacts the hard substrate 10 The area is defined as a patterned area 121 (shown in the figure after "FIG. 2-3"); 4. a patterned area 121 of the sensing layer 13 on the flexible polymer layer 12 is formed; Forming a protective layer 14 on the sensing layer 13; 6.

[0014] The following is a detailed explanation of each step: First, as shown in FIG. 1-1 and FIG. 2-1, a rigid substrate 10 is prepared, and the rigid substrate 10 is a rigid one. The substrate of the heat-resistant material can withstand the process temperature during the whole manufacturing process, and maintain its original shape without deformation; preferably, the rigid substrate 1 can have the characteristics of resisting strong acid and alkali, and can avoid The solvent erodes, for example, it is a glass substrate. [0015] Next, a discontinuous adhesive layer 11 is formed on a predetermined region of the hard substrate 10, and a flexible polymer layer 12 is formed on the adhesive layer 丨丨 and the hard substrate 10 as described in FIG. 2" to "Figure (4)" and "Figure 2_2" to "Figure 2-3". Here, the term "discontinuous" means that the adhesive layer is applied to the hard substrate 10 in a non-uniform manner, and is applied only to a region to be adhered. The adhesive layer 11 provides an effect of causing a portion of the flexible polymer layer 12 to adhere thereto by the adhesive layer n to adhere closely to the rigid substrate 10. The flexible polymer layer 12 is not bonded (or covered) to the region of the adhesive layer 11, that is, the range in which the flexible polymer layer 12 contacts the rigid substrate 10 is defined as a patterned region 121 (see "Fig. 2_3") The functional layers subsequent to (4) of the 'fine' can be formed in the patterned region 丨 21 on the flexible polymer layer 12. [0016] In the above-embodiment, the adhesive layer u may be made of organic matter and may be modified by physical laser or chemically engraved to form a special surface of the base (4). . In the above-described embodiments, the flexible polymer layer 12 is used as a flexible substrate for a touch panel, which can be spin coated (plus 099104570 Form No. A0101 Page 6 / Total 7 Pages 0992008605- 0 [0017] 201128476 ing), slit coating or blade coating, formed on the rigid substrate 10 and the adhesive layer 11; on the other hand, the glass of the flexible polymer layer 12 The glass transition temperature (Tg) can be higher than 15 (TC, and its material is transparent, with a low coefficient of thermal expansion (CTE) 'for example, p〇iyimide (PI), but not [0018] Ο ❹ [0019] In the following, please refer to "Figure 1-4" to "Figure 1-5" and "Figure 2-4" to "Figure 2-5" respectively The patterned region 211 of the flexible polymer layer 12 forms a sensing layer 13 and a protective layer 14 to form a stack of touch panels. The sensing layer 13 can be a touch panel. The dimensional sensing area ' can be a multi-layer structure, including a plurality of sensing units for sensing the X direction and the γ direction. The sensing units are arranged in an array manner; the protective layer 14 can protect the overall structure of the touch panel, has water blocking and gas barrier properties, can avoid being invaded by water vapor or organic solvent, or avoid The sensing layer 13 is damaged by an external force. In an embodiment, the insulating layer is an insulating transparent material. After the stacking structure of the touch panel is completed, the flexible polymer layer 12 and the sensing layer are then included. The touch panel structure of the protective layer 14 is removed from the rigid substrate 10. Please refer to "Fig. 6" to "Fig. 7" because the flexible polymer layer 2 is discontinuous. The adhesive layer 11 is adhered to the hard f substrate 1G. Therefore, the flexible polymer layer 12 of the patterned region 121 is cut in the manner of the hard substrate 10 (that is, the cut or unbonded) In the area of the adhesive layer, the cutting line is not shown in the dotted line of "Fig. 1 - 6", and the touch panel is directly separated from the hard substrate 10 by 099104570 Form No. A0101 Page 7 / Total 17 Page 0992008605-0 201128476. There is no coating of the adhesive layer 11 in the range of the δ hai patterned region 121, so The touch panel is easily detached from the rigid substrate 10. [0020] [0023] [0023] [The flexible polymer layer 12 is adhered to the hard substrate by the layer η 10 does not mean that there is no adhesion between the flexible polymer layer 12 and the rigid substrate 1 , in fact, the flexible polymer layer 12 can still bear the hard material by the adhesion of the material itself. On the substrate 10; however, the flexible polymer layer 12 itself has a smaller adhesion than the adhesive layer 11, and thus is easily separated from the rigid substrate. Compared with the prior art, the present invention fixes the flexible polymer layer 12 by the adhesive layer, and removes the flexible polymer layer 12 by the characteristics of the flexible substrate 10, so that the manufacturing cost is low. Moreover, the process is relatively simple and easy; on the other hand, through the invention, it is possible to avoid the problem that the prior art is easy to form residual glue or the material is destroyed due to the debonding process. The above is only the preferred embodiment of the present invention, and is not intended to limit the scope of the patent protection of the present invention, and the equivalent changes and modifications of the present invention using the specification and the drawings of the present invention are equally included in The scope of protection of the present invention is combined with Chen Ming.
