Detailed Description
Referring to fig. 1, a first embodiment of an identification tag for touch panel sensing according to the present invention is shown, wherein the identification tag of the present embodiment can be used for touch panel sensing. The identification tag 100 of the present embodiment includes a substrate 10 and a first identification layer 22.
The substrate 10 has a first surface 11 and a second surface 12, and the first surface 11 is opposite to the second surface 12. In the embodiment, the substrate 10 is made of an electrically insulating material, and may be a substrate made of a transparent material, such as a transparent plastic substrate or a transparent glass substrate, and the transparent plastic may be PET (polyethylene terephthalate), PE (polyethylene), PMMA (polymethyl methacrylate), PI (polyimide), PA (polyamide), PU (polyurethane), acrylic plastic, and the like. The thickness of the substrate 10 may be 10 to 500 micrometers.
Referring to fig. 2A and 2B, the first identification layer 22 is formed on the first surface 11 of the substrate 10. The first identification layer 22 includes a plurality of sensing regions 221 and a plurality of non-sensing regions 222. In the present embodiment, the plurality of sensing regions 221 are formed by a first conductive material.
When the plurality of sensing areas 221 correspond to a touch panel, that is, the identification tag 100 of the present invention is attached to the touch panel of the electronic device for sensing, the plurality of sensing areas 221 correspond to the touch panel and are sensed by the touch panel to generate a sensing value. In the present embodiment, the touch sensing area 22 includes a plurality of sensing areas 221 and a plurality of non-sensing areas 222, the sensing areas 221 are connected to the non-sensing areas 222, the sensing areas 221 are formed by the first conductive material, and the non-sensing areas 222 include a hollow structure formed between the first conductive materials. Therefore, when the capacitive touch panel senses the touch sensing area 22, the sensing area 221 is formed by the first conductive material, and therefore the touch panel senses the change of the capacitance value, and the non-sensing area 222 is a transparent structure, does not have the first conductive material, but the electrically insulated substrate 10 is directly exposed, so the touch panel does not sense the change of the capacitance value. By arranging and configuring the sensing regions 221 in different geometric shapes and different thicknesses of the dielectric layer, the touch panel can detect the sensing quantities formed by different capacitance values, thereby generating the identification function.
The first conductive material of the first identification layer 22 may use an organic, inorganic conductor coating or a combination of the above materials. The inorganic conductor may be a transparent conductive material of metal or metal oxide, such as Indium Tin Oxide (ITO), and the organic conductive layer may be a polymer substance PEDOT (polyethylene dioxythiophene), PEDOT: PSS (poly (ethylenedioxythiophene): poly (styrenesulfonic acid)), carbon nanotubes, or a combination thereof. The first conductive material may be formed on the first surface 11 of the substrate 10 by evaporation, sputtering, Chemical Vapor Deposition (CVD) or Physical Vapor Deposition (PVD), and then etched by a mask with a predetermined pattern to obtain the pattern of the first identification layer 22. In the present embodiment, the light transmittance of the first recognition layer 22 may be 70% to 95%.
In order to allow the touch panel of the electronic device (e.g., the touch panel of the mobile phone) to sense the sensing region 221, the sensing region 221 preferably has an area not smaller than 0.5 cm square, which is equivalent to the area of the touch panel touched by a finger. In addition, in order to increase the amount of induction, the sheet resistance of the first discrimination layer 22 is preferably lower than 1000 ohm/sq. In another embodiment, in order to further increase the sensing amount, the sheet resistance of the first identification layer 22 is preferably lower than 100 ohm/sq.
In addition, the identification tag 100 of the present invention includes a sensing region 221 separated by a non-sensing region 222.

In order to avoid a decrease in the amount of induction, the thickness of the protective layer 50 is preferably less than 500 micrometers (μm). In another embodiment, in order to further increase the sensing amount, the thickness of the protection layer 50 is preferably less than 100 μm.
