Problems solved by technology

[0002] In the prior art, indium tin oxide is generally used to make the touch electrodes of the touch screen. Indium tin oxide has good optical and electrical comprehensive properties, but compared with metal materials, the impedance of indium tin oxide is still high, which leads to touch The electrical effect of the screen needs to be improved
[0003] And because the visible light reflectance of indium tin oxide is relatively high (about 11%), which is greater than the visible light reflectance of the glass substrate (about 4%), after the touch display device is formed by attaching an external touch screen on the display , the reflectivity of the touch display device will be relatively large, and the visual effect will be poor

Embodiment 1

[0045] This embodiment provides a transparent conductive film, which includes a transparent inorganic insulating layer, a metal layer and a transparent metal oxide conductive layer stacked, wherein the refractive index of the transparent inorganic insulating layer is less than 1.5.

[0046] In this embodiment, the transparent conductive film is composed of a stacked transparent inorganic insulating layer, a metal layer and a transparent metal oxide conductive layer. Adopting this structure can make the transparent conductive film have a low reflectivity and the conductivity is not weaker than that of metal. The transparent conductive film is used as the touch electrode of the touch screen, which will not affect the transmittance, but also can reduce the resistivity of the touch electrode, improve the electrical effect of the touch screen, and can also reduce the reflectivity of the touch screen. Further, the visual effect of the display device adopting the touch screen is impro...

Embodiment 2

[0057] This embodiment provides a substrate, including a plurality of signal transmission lines formed on the base substrate, and the signal transmission lines are made of the above-mentioned transparent conductive film.

[0058] In this embodiment, the signal transmission line of the substrate is made of a transparent conductive film. The transparent conductive film is composed of a transparent inorganic insulating layer, a metal layer and a transparent metal oxide conductive layer, so that the transparent conductive film has a low reflectivity and is conductive. The performance is not weaker than that of metal. Using the transparent conductive film to make signal transmission lines can not only meet the requirements of resistivity, but also because of its transparency, it can save the need to set up a black matrix that blocks signal transmission lines.

Embodiment 3

[0060] This embodiment provides a touch screen, and the touch electrodes of the touch screen are made of the above-mentioned transparent conductive film.

[0061] In this embodiment, the transparent conductive film is composed of a stacked transparent inorganic insulating layer, a metal layer and a transparent metal oxide conductive layer, so that the reflectance of the transparent conductive film is low and the conductivity is not weaker than that of metal. The touch electrode of the touch screen will not affect the transmittance, but also can reduce the resistivity of the touch electrode, improve the electrical effect of the touch screen, and can also reduce the reflectivity of the touch screen, thereby improving the use of touch screen. The visual effect of the display device of the screen.

[0062] Furthermore, the touch electrode bridging and / or signal transmission lines of the touch screen can also be made of transparent conductive film, and the use of the transparent co...
