Claim:
1. A conductive film comprising: a substrate having a first surface and a second surface opposite to the first surface; a first matrix layer adhered to the first surface, wherein the first matrix layer is formed by curing a gel coating, and a first grid groove is formed on a side of the first matrix layer away from the substrate, with the first grid groove being filled with a conductive material to form a first conductive layer; a second continuous matrix layer directly adhered to the side of the first matrix layer away from the substrate, wherein the second continuous matrix layer is formed by curing a gel coating, and a second grid groove is formed on a side of the second continuous matrix layer away from the first matrix layer, with the second grid groove being filled with a conductive material to form a second conductive layer; and a light-shielding layer adhered to an edge of the side of the second continuous matrix layer away from the first matrix layer, wherein a second non-visible region is formed in an area where the second continuous matrix layer is adhered with the light-shielding layer, and a first non-visible region is formed in a projection area of the light-shielding layer on the first matrix layer, with the first grid groove extending to the first non-visible region, and the second grid groove extending to the second non-visible region; wherein a first through-hole is formed in the light-shielding layer, the first through-hole runs through the light-shielding layer and the second continuous matrix layer, and communicates with the first grid groove, and the first through-hole is filled with a conductive material to form a first lead electrode, the first lead is electrically connected to the first conductive layer; and there is a second lead electrode on a surface of the light-shielding layer, and the second lead electrode is electrically connected to the second conductive layer, a second through-hole is formed in the light-shielding layer that runs through the light-shielding layer and communicates with the second grid groove, and the second through-hole is filled with a conductive material that is electrically connected to the conductive material of the second conductive layer, wherein the first grid groove and the second grid groove have a width of 1 to 5 microns, a depth of 2 to 6 microns, and a depth-to-width ratio of greater than 1, the first conductive layer and the second conductive layer have a transmittance of greater than 85%, and the first matrix layer and the second continuous matrix layer are a single layer, respectively.
