Please continue to refer to the fifth®, which is the third variation of the composite layer with the control panel of the present invention. In order to reduce the overall flight rate of the touch panel 5G, it is preferable to perform anti-reflection treatment on the composite layer 23 in a stepwise manner; the touch panel % in the fifth figure mainly includes a lower conductive layer Μ , the upper conductive layer 52, the glass, the IT layer Μ 2, and the anti-reflective layer ^; the glass in the composite layer 23 and the enamel layer is coated with an intermediate layer (Cai (4) an anti-reflective layer 55, thereby effectively reducing the touch _5〇's overall reflectivity to avoid obstructive light when used in brighter places. 'In this embodiment, the composite layer is composed of glass exhaust, ιτ〇 attack and anti-reflective layer 55; Further, a low birefringence plastic substrate, such as germanium, optical polycarbonate, safety glass or tempered glass, can be used as the material of the lower conductive layer to the first substrate, and the overall reflection of the touch panel can be effectively reduced. It is worth noting that the composite layer of the present invention can be applied to the side of the touch wheel human device by optical glue or the like after the touch input device is completed. Example 'composite layer 23 can be touched After the device is manufactured, it is attached to the side of the touch input device 21 by optical glue 22 or the like according to actual needs. Accordingly, the present invention further proposes a touch panel manufacturing method. As disclosed in the sixth figure, step 601 is included: first, the touch input device is fabricated; step: placing the composite layer sS: on the side of the female input device, the thickness of the composite layer of the towel is less than 3 mm; It is noted that the steps may be implemented after the touch input device is completed. The completed 201106046 includes the completed touch input device that has been fully functional, has been used, or is further advanced. Already _ the original birth record, and shipped copper to other remote occasions. It should be noted that the subject matter of the present invention has the knowledge of the first to third variants of the foregoing, and the above-described first to third variant embodiments can be easily combined to derive more variant embodiments, which are the only ones of the present invention. The preferred embodiments are not intended to limit the scope of the invention. That is to say, the changes made by the patent system in accordance with this issue and (4) should still fall within the scope covered by the patent of the invention. I would like to ask your review committee to give a clear explanation and pray for it. It is the prayer.
