In particular, the substrate may be a transparent thin plate or a transparent composite plate in which a plurality of transparent thin plate adhesives M412413 are integrated; the plurality of transparent transparent plates may use the same or different materials. In particular, the transparent sheet is a non-planar sheet of a flat or convex or concave surface, the material of which is selected from glass or polycarbonate (PC), polyester PET, polyacrylic acid vinegar (PMMA) or Cycloalkane copolymers (coc), etc., but the range of materials to be implemented is not limited to the above materials, and various types of soft or rigid, transparent or translucent substrates are suitable. In particular, the aforesaid identity target may also be a pair of positioning marks respectively disposed on the upper and lower main surfaces of the substrate in the process, and the position of the pair of positioning marks is the same vertical through the upper or lower main surface. Axis. In particular, the distances between the identical targets are placed as far apart as possible from each other. This will further clarify other functions and technical features of the present work, which will be realized by those skilled in the art after reading the description in the text. [Embodiment] In the following embodiments, a capacitive touch panel will be described as an embodiment. However, the scope of implementation of the present invention is not limited to the use of a capacitive touch panel, such as a resistive touch panel or an electromagnetic touch. The panel can also be applied. As shown in the first and second embodiments, the touch panel structure includes an upper protective layer 4〇a, an upper signal guiding layer 3〇a, and an upper layer. a sensing electrode layer 20a, a transparent substrate 1〇, a lower sensing electrode layer 2〇b, a lower signal guiding layer 30b, and a lower protective layer 40b; wherein the transparent substrate 1〇 material 5 M412413 is selected from the group consisting of glass and poly Carbonate, polyester, polymethyl methacrylate or cycloolefin copolymer, etc., but the material range of the implementation is not limited to the above materials, all kinds of soft or rigid, transparent or translucent substrates are applicable; the above upper and lower The sensing electrode layers 20a and 20b are formed of a transparent thin film of indium tin oxide (ITO) or indium zinc oxide, and the upper and lower sensing electrode layers 20a and 20b are respectively provided with X-axis sensing stitches and γ-axis sensing stitches; The upper and lower signal guiding layers 30a and 30b are metal ore films made of silver, copper, sin (^/Α1/Μ〇) or silver-copper (Ag/Pu/Cu), and are yellow-lighted. The process is to form a signal guiding path and overlap the sensing electrode layer; and the upper and lower protective layers are galvanized and the material may be Fossil eve, oxidized stone, photoresist, etc., or a hardenable adhesive layer such as UV optical glue, or transparent glass, polycarbonate or vinegar sheet, but the material is implemented. The range is not limited to the foregoing materials, and the protective layer gamma and 4 〇b are respectively disposed on the upper sensing electrode layer 2a and the upper signal guiding layer and the lower sensing electrode layer 20b and the lower signal guiding layer 3 The outermost side of the % to avoid scratch damage to the sensing electrodes and signal guides. Specifically, in the above structure, in the embodiment, the substrate 10 is provided with two holes 105' penetrating the plate body and perpendicular to the upper or lower main surface of the substrate, and the holes 105 are disposed at The area of the touch panel other than the touch sensing area Ατ, by the setting of the signal K) 5, regardless of the position of the plane coordinates on the upper and lower main surfaces of the occupational board, the holes can be used as The dry standard of the grain provides the alignment reference of the touch panel in each processing county; and the distance between the aforementioned holes is preferably set in a different amount, which can increase the positioning accuracy; it is understandable that The substrate 10 is not provided with two holes 105 for positioning. In fact, if more holes are provided on the substrate, the precision of the positioning will be improved, but the labor cost and the strength of the substrate will be increased. Therefore, the number of holes provided on the substrate is preferably determined by the design of the workpiece holder used in the processing; by providing the through holes 105 on the substrate 10 as a registration reference in the process, when the substrate is Upper and lower main surfaces At the same time, various processing processes can accurately position each overlapping layer, thereby obtaining the upper and lower sensing electrode layers with extremely high alignment freshness, and achieving the defect rate of the health products and improving the optical characteristics of the panel. Conceiving, the holes 105 may also be replaced by a plurality of shapes of various shapes disposed on the edge of the substrate 10 and perpendicular to the upper or lower main surface of the substrate: 1〇6 (such as the third and fourth riding) Or it may be a positioning mark 1〇7 (as shown in FIG. 6) carved by the laser technology in the plate body of the substrate 10, or may be placed on the substrate 10 , the lower surface of the face - the dare sign, the 嶋, and the position of the pair of positioning is through the upper or lower main table = the same vertical axis l 〇 8c (as shown in the seventh and eighth figures). _ rigid material - lion basic structure can be adjusted according to different use conditions of the control panel, for example: the fifth embodiment shown in the ninth figure, which is based on the configuration of the foregoing first embodiment Signal Guide Layer = Upper Surface Coverage - Adhesive layering for attaching a color edge layer (^) to a cover plate (C0ver Lens) 70 and a functional film 9〇, and below, The composition of the color frame 60 may be ink 'color grade, organic material M412413 or inorganic material, but the range of materials that can be implemented is not limited thereto, and the foregoing materials are set by technical means such as printing, coating, metal evaporation and the like. The peripheral portion of the bottom surface of the surface cover is not limited by the above technical means. The color frame can directly cover the upper and lower signal guiding layers formed on the outer peripheral edge of the transparent substrate 10 to The purpose of the aesthetic appearance of the panel; in addition, the functional film 9 can be an anti-fingerprint layer, an atomized film layer or a hard coating film layer, thereby preventing surface contamination, reducing the reflectivity of the touch panel surface, or lifting the panel surface Hardness and The squeegee functional film 90 may be a film having a light-adjusting function, for example, a combination of a polarizing film, a phase difference _ or an optical film such as an optical film, or a combination of two or more film layers. Light-adjusting film 'to enhance the visibility of the display. Also in the sixth embodiment shown in the tenth fiscal, the planar surface cover 70 of the fifth embodiment is replaced with a convex surface cover 7 having a curved surface. As can be understood, this non-flat type The surface is covered by the surface of the aforementioned convex surface, and may be a curved concave surface or a concave or convex surface provided by each silk carving or residual. This creation is not a form described in the ship alone. (4) With reference to the above description, there can be more improvements and changes in the technical uniformity, such as: according to the structure of any of the above embodiments, the transparent substrate can be a single one. In addition to the transparent thin plate, a transparent composite plate which is bonded and laminated by a plurality of transparent thin plates may be used, for example, a transparent adhesive layer is bonded between the first and second transparent substrates H)a, H)b. Together, the first and second transparent substrates of the above-mentioned composite composite panel can be used, and the same or different materials can be used for 1%, and the change settings are achieved as described above. ·- or similar performance, it should be substantially the same as the 8 M412413 technology before the creation; therefore, any modifications or changes to the creation made under the same creative spirit should still be included in the creative intent.
