Conventional_control panel has a multi-layer structure, for example, the resistive touch panel includes a thinned or squid button, a metal conductive film (usually indium tin oxide) plated on the substrate, and a dot interval between the two conductive films DotSpacer, etc., due to the limitations of material selection, plus the lamination of the multilayer film, so that the material towel or the material itself absorbs the blue-violet light in the silk, which leads to the optical properties exhibited by the touch panel structure. The light passing through the touch=board will be yellowish, that is, the value of the L*a*b* color space (Lab C〇l〇rspace) is generally high, which will cause the screen of the display to be affected. The influence causes the distortion of the original display surface to cause inconvenience to the user, and the quality of the product is lowered. In the past, in order to solve this problem, panel manufacturers have to spend a lot of money and time trying to change the optical characteristics of the touch panel from materials and processes, and to search for or not to emit light through the light. However, such a scheme makes the manufacturing cost of the product too high and the material is limited, which is obviously not conducive to market competition. For the sake of the job, the applicant, based on the lack of knowledge in the prior art, passed the test and research of the heart, and the spirit of perseverance, finally conceived that the case "touch panel and silk green" can touch Social justice point, the following is the simple example of this case 5 201005369 To explain.

In the present invention, the optical mineral film is used to set the age of the L*a*b* color space_space, so that the brain of the brain touch panel is not excessively large (10), and the color of the touch panel appears. Yellow phenomenon. Therefore, the optical coating needs to control its reflectance. That is to say, the optical surface and the adjacent fine refractive index are produced to produce a high and low refractive index difference to suppress the reflection of the relatively short wavelength blue light in the visible light to achieve the effect of controlling the b value. Please refer to the first embodiment, which is a first embodiment of the touch panel provided by the present invention. The touch panel 1 includes an upper conductive layer U, a lower conductive layer 12, a spacer layer 13, an optical coating film 14, and an upper substrate 16. Lower substrate π. Generally, the upper conductive layer u and the lower conductive layer 12 are respectively formed on the first upper substrate 16 and the lower substrate 17 of a suitable thickness with an appropriate thickness, and the gap between the upper conductive layer and the lower conductive layer 12 is generally referred to as a dot spacer. The layers 13 are spaced apart to avoid a short circuit and no malfunction when there is no touch. However, before the upper conductive layer U and the lower conductive layer are formed on the upper substrate 16 and the lower substrate 17, an optical coating 14 may be formed on the lower substrate 17 to make the refractive index of the 5th optical forged film 14 lower than the lower conductive layer 12. The refractive index is between 9 and 201005369 between the refractive index of the substrate 17. It is known to those skilled in the art of radiation that the reflectivity is a function of wavelength, thickness of the M layer and refractive index. 'If the thickness and refractive index are determined values, then the reflectivity is only a function of the wavelength, so the optical imaging system of the present invention The minimum reflectance wavelength, the minimum reflectance wavelength of the optical coating 14 is controlled at a relatively new wavelength of light, that is, a range of 38 〇 to 5 〇〇 nm, so that the blue reflection can be suppressed by the optical coating 14 The yellow light generated by the upper conductive layer 1 , the lower layer 13 , the upper substrate 16 , and the lower substrate is formed by the conventional conductive material, and the b value of the overall touch panel is adjusted. Approaching 〇. In addition, in addition to the spacer layer 13, the optical coating μ can be present in any layer of the control panel towel, and only the high-low refractive index difference of the control layer can reduce the blue reflection. According to the above-mentioned concept of the touch panel, the manufacturing method is to provide the substrate 17 'the lower substrate 17 such as glass, polycarbonate, polymethyl methacrylate (PMMA) or polyester plastic ( P〇ly Do not lyleneTe which hthalate, PET), polyethylene, polyolefin (p〇ly〇lefin) • and other transparent materials are composed of appropriate thickness. Then, the optical coating film 14 is formed on the lower substrate 17 in a conventional manner. The optical coating 14 must be a transparent, non-conductive material, and is mainly composed of an organic compound, an inorganic compound, or a group of the former two. The organic compound may be an epoxy resin (Epoxy Resin), a polyamidide, an acrylic, a polycarbonate (p〇lycarb〇nate), a polyester plastic or the like. The inorganic compounds are cerium oxide (Nd203), oxidized (Zr〇2), indium oxide (ΙηΛ), titanium oxide (Ti〇, Ti〇2, Ti2〇3, Ti3〇5), alumina (ΑΙΛ), oxidation. Metal oxides such as magnesium (Mg〇), yttrium oxide (Hf〇2), oxidized sharp (Can do), yttrium oxide (Ta2〇5), zinc oxide (Zn〇) or magnesium fluoride 201005369 (MgF2), I YbF3, LaF3, 败yF3, NdF3, ErF3, fluorinated (KF), fluorinated pin (SrF3), fluorinated A metal fluoride material such as strontium (S111F3), sodium fluoride (NaF), barium fluoride (BaF2), or cesium fluoride (CeF3) or a borosilicate-based material. These materials are formed into optical coatings 14 by appropriate selection or mixing in an appropriate ratio. On the optical coating 14, a conductive layer 12 of a suitable thickness is formed by a method such as steaming, sputtering, electrominening, chemical vapor deposition (CVD), wet coating or the like. The lower conductive layer 12 is made of, for example, a material of Indium Tin Oxide (ITO). A spacer layer 13 is formed on the lower conductive layer 12, and a conductive layer 11 of the same material as the lower conductive layer 12 and a substrate 16 of the same material as the lower substrate 17 are formed on the upper portion of the touch panel made of a suitable thickness. Engaging with the spacer layer 13 completes the touch panel 1 proposed in the present application. It should be particularly emphasized that although the touch panel j in the above embodiment is a resistive touch panel, the invention is not limited to the resistive touch panel, and includes a capacitive type and the like as long as it has L*a*. The touch panel of the b* color space with the positive b characteristic of the color space belongs to the applicable range of the invention of the present invention. Through the technical content disclosed above, the reflection of blue light can be suppressed by the reflectance of the optical coating to achieve the purpose of controlling the b value of the L*a*b* color space, so as to produce a touch panel that does not produce a yellowish color. Not only can reduce material costs, but also meet market demand. This case is a rare and rare invention that is cherished, but it is only the preferred embodiment of the present invention, and the scope of the invention is not limited thereto. That is to say, the equivalent changes and modifications made by the applicant in accordance with the scope of the patent application of the present invention should still fall within the scope covered by the patent of the present invention. I would like to ask you to review the Mingjian, and pray for the best.
