As shown in FIG. 2, the structure of the conventional touch panel 1 包括 includes a glass plate 11 , and the upper surface of the glass plate 11 is glued with a layer ΙΤ 0 conductive film 13 , and the uppermost layer The main manufacturing step of the conventional touch surface (4) is as follows: the upper surface of the glass substrate 11 is cleaned, and the optical adhesive 12 is coated on the upper surface of the glass substrate u, which is electrically conductive. The film 13' is coated with the optical adhesive 14 on the conductive film 13, and the structure of the conventional touch panel and the method for manufacturing the same are present in the town: a complicated processing process, high cost, and low yield: ΙΊΌ conductive film 13 glued on the upper surface of the glass substrate 11 ' ΙΤ 0 $ film 13 is very fragile, it will be damaged when touched a few times 'can not be directly used as the operation surface' must be glued on top of a layer of stone stone (5) as the operation surface, therefore, After at least two processes of gluing and gluing, it is necessary to put in multiple production lines at a high cost; and it is difficult to ensure the uniformity of the coated optical glue when it is made, and bubbles are easily generated during the gluing process, plus glass. The fragility of all of this 201140200 has led to a lower yield of touch panels. 2 Anwang is poor. Lion glass is used as the substrate and operation surface. The glass is fragile. Any bad section of processing, transportation, storage and use may be damaged and broken, so there is a high safety hazard. 3, poor penetration rate · glass transmittance of the phase can be Lona, but because there are two layers of glass and coated with two layers of optical glue, affecting the glass through the green fruit, which leads to the transmittance of the touch panel The maximum can only reach 80%. 4,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, SUMMARY OF THE INVENTION An object of the present invention is to provide a method for manufacturing a touch panel and a product thereof, which can simplify the manufacturing process of the touch panel, and the structure of the control panel is simple and easy to process, which can ensure the protection and use. Security. In order to achieve the above object, the present invention provides a touch panel manufacturing method and a product thereof. The touch panel manufacturing method includes at least the following steps: an ejection step of forming a transparent plastic substrate by an injection compression molding method; a step of directly printing at least one printed layer on a lower surface of the substrate; at least a step of plating a conductive surface, forming at least one conductive film on a lower surface of the substrate. Also included is at least a "money optical filming step" wherein the upper surface of the substrate is further formed with at least one layer of optically rhodium. The order of the step of the conductive step of the clock, the printing step, and the step of the optical forging film of the clock can be adjusted according to the manufacturing method. A touch surface defect is processed by a manufacturing method including at least an - ejecting step, a printing step, and a step of plating a conductive film. A transparent plastic substrate is formed by an ejection step, and a printed layer is directly printed on the lower surface of the base (4) by a step, and a conductive film is formed on the lower surface of the plastic substrate by a step of conducting a conductive film. Because plastic has the advantages of light weight, low cost and high safety, it is more suitable for the substrate of the touch panel than glass, but because of the colorful, stress and variable material problems of the traditional injection molded fine plastic plate, the traditional injection molding The present is still unable to be used in the field of touch panels. 'The inventor disclosed in the patent _155 - - 种 种 种 种 种 种 , , , , , , , , , , , , , , , 职 职 职 职 职 职 职 娜 娜 娜 娜 娜 娜 娜The inventor relied on his own years of experience in the plastics electronics industry, and through the creative research of the patent, applied the invention of the patent to the field of touch panels, and confirmed the production of injection-molded compression molds through the experiments of (4). The feasibility and superiority of the plastic plate as a touch panel. The invention has a series of beneficial effects brought about by the use of a plastic plate which is reinforced by the injection step as a substrate. 1. The simplification of the manufacturing process of the touch panel and the reduction of the production cost. The direct printing and plating of the conductive film on the lower surface changes the process of bonding the printed contact panel to the surface layer and bonding the conductive film between the two layers of glass with optical glue, which greatly simplifies the manufacturing process and enables mass production through assembly line operations. Thereby reducing production costs. 201140200 2. The touch panel is simple in structure and thin in thickness: the conductive film is directly formed on the lower surface of the substrate, so that the upper surface of the substrate is directly used as the operation surface, without separately constructing other operation surfaces, and the touch panel thus processed The single-substrate type has a simpler structure, and the single-substrate type has a structure that greatly reduces the thickness of the product compared to the structure of the two-layer glass. 3. Replacing the conventional glass substrate with a plastic substrate can ensure the safety of the processing and use of the touch panel: the plastic substrate processed by the injection compression molding method does not have problems such as colorful, stress and deformation, and is more suitable for doing. The substrate of the touch panel can overcome the fragility of the conventional structural glass and ensure the safety of processing and use of the touch panel. [Embodiment] Referring to FIG. 2, the touch panel manufacturing method 2b mainly includes the following steps: an injection step 21 is a method of forming a transparent plastic substrate by using an injection compression molding method, #一印刷步骤22, The printed layer is directly printed on the lower surface of the substrate, and the printed layer can be formed by using general ink printing to form a frame, a 〇g〇 or other decorative pattern, or a soluble ink, a conductive ink or an optical ink. Performing printing 'to meet the functional requirements; one optical optical film step 23 is to directly mine the optical forged film on the upper surface of the substrate; the conductive conductive film step 24 '疋 on the lower surface of the substrate to record the conductive film; For the specific process of the injection step 21, please refer to FIG. 3, the injection compression mold 30 includes an upper mold 31 and a lower mold 32. A movable platen 31 is disposed on the 201140200 between the upper mold 31 and the lower mold 32. Forming a mold cavity 33, the upper mold 31 plate 310 is driven up and down by the compression mechanism 34, so that the mold cavity has a variable volume characteristic, material 35(4) σ Injecting the mold cavity, the movable platen 310 moves toward the lower mold 32, and the lower surface compresses the material 35 so that the material is uniformly filled in the mold cavity 33. The thus-formed substrate has a uniform structure, which overcomes the colorful, stress and deformation of the ordinary injection-molded sheet. The substrate is made of acrylic, the Qianli has high light transmittance, and the silky Dana and acrylic are combined. It has good surface hardness and gloss, _good, no damage, and is more suitable for use as a substrate for a touch panel. Because the surface printing of glass has very high requirements on surface treatment, temperature, printing pressure and other process conditions. In order to reduce the cost, the touch panel is generally used to frame the logo, logo and other decorations on the outer surface of the glass panel. It is visually relatively rigid and easy to fall off during use. In the printing step 22, the frame, logo and other decorative patterns are directly printed on the lower surface of the substrate as a printed layer, and are seen through the upper surface of the substrate. The printed layer has a three-dimensional and embossed feel, which can increase the visual beauty without the problem of falling off. The conventional touch panel is formed by etching on the conductive film, and the immersion method is required to immerse the panel in the chemical etching solution to make the conductive 臈The part other than the electrode pattern is completely reacted with the etched liquid element to form an electrode pattern. The disadvantage is that the work raft is more complicated, the etchant is acidic or alkaline, and the conductive film is damaged during the immersion process. A large environmental pollution is also generated during the treatment, and the present invention can directly print a lower surface of the substrate in the printing step 22. The layer of soluble ink is used to cover the portion of the conductive film 201140200 after the electrode _, after the conductive film on the mine, the conductive film will cover the soluble ink, after washing, the soluble ink dissolves, and the part other than the conductive film electrode pattern The soluble ink is washed away, thus omitting the process of the conductive film side, avoiding the damage to the conductive film during the soaking process in the acid domain, simplifying the process and the process, and having the effects of being effective, quick, environmentally friendly, time-saving, and water-saving. In addition, the printed layer can also be a conductive ink and an optical ink to meet other functional requirements. In the step of coating the optical mineral film, the optical coating is directly formed on the upper surface of the substrate. The optical surface can improve the transmittance of light, (4) increase the transmittance of the surface of the panel, and can refract harmful light and enhance surface hardness, and Anti-static, anti-glare and anti-peep effects are achieved. In the conductive film step 24, the conductive film is directly formed on the substrate by means of electric ore, splashing or steaming. The following table is mounted on the substrate: 'The substrate is tilted, and the upper surface of the plate can be directly used as the operation surface' without additionally constructing other The operating surface, so that the touch panel becomes a monofilament plate structure, but simplifies the _ surface structure, and greatly reduces the thickness of the touch panel. The sequence of the steps of the above manufacturing method can be adjusted as needed, such as first performing the electro-membrane step 24' and then performing the recording optical ray 23, and the steps of the manufacturing method are sequentially changed and dropped into the present invention. And, as needed, the printing step, the ore optical film step 23, and the key conductive film step 24 may be repeated twice or more respectively. The monthly method of this method is simple. 'The requirements for the process conditions are not high. It can be mass-produced through the assembly line operation, and the production cost of the touch panel is reduced from the large. Referring to the 4th and 5th, the 201140200 touch panel 40 processed by the above steps includes a transparent substrate 41 which is a transparent plastic plate processed by the shooting step 21, and the substrate The lower surface of 41 is a printed layer 42 printed by a printing step, and the printed layer 42 can be a frame, a logo, a decorative image, or a soluble ink, a conductive ink, or an optical ink, as shown in FIG. 4, As shown in FIG. 5, the printed layer 42 is a frame, and at least the layer of the IT conductive film 43 is directly plated on the lower surface of the substrate 41 by the step of plating the conductive film. Please refer to FIG. 6 for the printed layer. 42 is a soluble ink, a conductive ink or an optical ink. At least one layer of the ITO conductive film 43 is plated on the lower surface of the substrate 41 by the conductive film step 24, and covers the printed layer 42. The upper surface of the substrate 41 is subjected to a plating optical coating step. 23 is formed with at least one optical coating 44 as a protective layer.
