  • Publication number: 20140253827
    Abstract: A conductive film includes a substrate, a first matrix layer, a first conductive layer, a second matrix layer, and a second conductive layer. The substrate includes a first surface and an oppositely arranged second surface. The first matrix layer is attached to the first surface. The first conductive layer is embedded in the first matrix layer. The second matrix layer is attached to a side of the first matrix layer away from the substrate. The second conductive layer is embedded in the second matrix layer. Due to the capacitor formed between the first conductive layer and the second conductive layer, it just needs to attach the conductive film to a glass panel when the conductive film is adopted to manufacture a touch screen, without bonding two pieces of conductive films. Therefore, the touch screen using the conductive film has a smaller thickness. In addition, a method for manufacturing the conductive film and a touch screen including the conductive film are also provided by the present disclosure.

  • Publication number: 20140218637
    Abstract: A conductive film includes a substrate, a first conductive layer, a matrix layer, and a second conductive layer. The substrate includes a first surface and an oppositely arranged second surface. The first conductive layer is embedded in the substrate. The matrix layer is set on the first surface of the substrate. The matrix layer is formed by solidified jelly coating. The second conductive layer embedded in the matrix layer. The second conductive layer is insulated from the first conductive layer. Due to the capacitor formed between the first conductive layer and the second conductive layer, it just needs to attach the conductive film to a glass panel when the conductive film is adopted to manufacture a touch screen, without bonding two pieces of conductive films. In addition, the matrix layer, formed by solidifying the jelly painted on the substrate, is with a much smaller thickness than the substrate. Therefore, the touch screen using the conductive film has a smaller thickness.

  • Publication number: 20140216804
    Abstract: A transparent conductive film includes a substrate defining a mesh-shaped groove, which forms a mesh; and a conductive layer formed by conductive material filled in the mesh. An edge line of the mesh-shaped grooves is a curve or a polyline which increases a contact area between the conductive material and an edge of the mesh-shaped groove. In the transparent conductive film, non-linear edge lines are used, therefore, for the conductive region with the same size, the area of edge of the conductive material in contact with the trench increases, and the friction is increased, which leads to a larger adhesion of the conductive material, and a stable performance of the transparent conductive film is guaranteed.

    Abstract: The present invention discloses a patterned transparent conductive film based on the random grid, wherein the surface of the conductive film can be divided into a conductive region and an insulating region, with the conductive region having the grid made of metal. The grid of the conductive region, composed of the grid line of the conductive region, is a random grid having an irregular shape, and can avoid periodic shielding generated by the opaque metal grid lines and the periodic pixel unit of LCD. The patterned transparent conductive film provided by the present invention is composed of the irregular random grid, and therefore will not generate the Moire stripe. Besides, finally by naked eyes observation, the conductive region and the insulating region have exactly the same or close transmittance, and therefore will not generate the grayscale contrast.
