Embodiment 1

[0040] This embodiment provides a transparent conductive film, which includes a metal oxide layer, a metal layer and a metal oxide layer stacked together.

[0041] In this embodiment, the transparent conductive film is composed of a stacked metal oxide layer, a metal layer and a metal oxide layer, so that the transparent conductive film is transparent and its conductivity is not weaker than that of metal. The transparent conductive film can be used to make signal transmission lines and The electrode can meet the resistivity requirement without affecting the transmittance.

[0042] In a specific embodiment, the transparent conductive film is composed of a first indium gallium zinc oxide layer, a first manganese oxide layer, a metal layer, a second manganese oxide layer and a second indium gallium zinc oxide layer, and the indium gallium zinc oxide Both the manganese oxide layer and the manganese oxide layer are transparent in the visible light region. By using the principle of ...

Embodiment 2

[0046] This embodiment provides a substrate, including a plurality of signal transmission lines formed on the base substrate, the signal transmission lines are made of a transparent conductive film, and the transparent conductive film includes a stacked first metal oxide layer, a metal layer and a second metal oxide layer.

[0047] In this embodiment, the signal transmission line of the substrate is made of a transparent conductive film, which is composed of a stacked metal oxide layer, a metal layer and a metal oxide layer, so that the transparent conductive film is transparent and its conductivity is not weaker than Metal, using the transparent conductive film to make signal transmission lines can meet the resistivity requirements without affecting the transmittance.

[0048] In a specific embodiment, the transparent conductive film is composed of a first indium gallium zinc oxide layer, a first manganese oxide layer, a metal layer, a second manganese oxide layer and a secon...

Embodiment 3

[0052] This embodiment also provides a touch screen, including the substrate as described in Embodiment 2, and the signal transmission line is a touch signal transmission line connected to the touch electrodes of the touch screen.

[0053] In this embodiment, the touch signal transmission line of the touch screen is made of a transparent conductive film, which is composed of a metal oxide layer, a metal layer and a metal oxide layer stacked so that the transparent conductive film is both transparent and conductive The performance is not weaker than that of metal. Using this transparent conductive film to make signal transmission lines can not only meet the requirements of resistivity, but also because of its transparency, it is not necessary to set up a black matrix that blocks touch signal transmission lines in the edge area, so that the touch screen can be realized. without borders.

[0054] Further, the touch electrodes of the touch screen can also be made of a transparent ...

Description

technical field [0001] The invention relates to the field of display technology, in particular to a transparent conductive film, a substrate, a touch screen, a manufacturing method thereof, and a display device. Background technique [0002] With the development of the touch screen industry, based on market demand, touch screens tend to be borderless. [0003] At present, the frame around the touch screen is generally made of metal to make signal transmission lines. The metal wiring has the characteristics of good conductivity, narrow line width, and low resistance, which can meet the needs of narrow frames. However, due to the opacity of metal, it is impossible to use metal wiring to make signal transmission lines to achieve a borderless touch screen; in addition, although transparent conductive films such as ITO have high visible light transmittance, their resistivity is relatively large, so , It is also impossible to use transparent conductive materials such as ITO to ma...
