Problems solved by technology

Since the conductive films obtained by the embossing process are relatively thin, it is easy to make the thickness of the second metal buried layer the same or almost the same as the thickness of the second polymer layer during the embossing process, so that the first metal buried layer and the second metal buried layer An electrical connection occurs between the metal buried layers, which leads to a short circuit between the first metal buried layer and the second metal buried layer, resulting in a low product process yield

Embodiment 1

[0037] Such as figure 1 As shown, this embodiment discloses a double-layer transparent conductive film, including a transparent substrate 1, a first conductive layer 3 disposed on the transparent substrate, and a second conductive layer 6 disposed on the first conductive layer 3, so A transparent insulating support layer 4 is disposed between the first conductive layer 3 and the second conductive layer 6 , and the second conductive layer 6 is disposed on the cured transparent insulating support layer 4 .

[0038] The transparent substrate 1 is provided with a first transparent adhesive layer 2, and the first conductive layer 3 is composed of a conductive material embedded in a plurality of grid grooves on the first transparent adhesive layer 2; the transparent insulating A second transparent adhesive layer 5 is disposed on the support layer 4 , and the second conductive layer 6 is composed of conductive material embedded in a plurality of grid grooves on the second transparent...

Embodiment 2

[0055] Such as figure 2 As shown, this embodiment discloses a double-layer transparent conductive film, including a transparent substrate 1, a first conductive layer 3 disposed on the transparent substrate, and a second conductive layer 6 disposed on the first conductive layer 3, so A transparent insulating support layer 4 is arranged between the first conductive layer 3 and the second conductive layer 6, and the second conductive layer 6 is arranged on the cured transparent insulating support layer 4;

[0056] The only difference from the first embodiment is that the first conductive layer of the second embodiment is formed by conductive material filled in grid grooves opened on the transparent substrate 1 .

[0057] It should be noted that, compared with the first embodiment, the first transparent adhesive layer is removed in the second embodiment, which is equivalent to a thinner thickness of the double-layer transparent conductive film. However, the effect of directly emb...

Description

technical field [0001] The invention relates to the technical field of conductive thin films, in particular to a double-layer transparent conductive film and a preparation method thereof. Background technique [0002] Transparent conductive film is a film with good electrical conductivity and high light transmittance in the visible light band. It has been widely used in flat panel displays, photovoltaic devices, touch panels and electromagnetic shielding, and has a broad market space. Due to the various disadvantages of ITO, metal mesh transparent conductive films are playing an increasingly important role. [0003] A double-layer transparent conductive film is disclosed in CN201210412895.0, which uses patterned embossing technology to emboss a groove structure on the first polymer layer and the second polymer layer, and then fills the metal conductive film in the groove structure. The material forms a first metal buried layer and a second metal buried layer, wherein the se...
