  • Patent number: 8993896
    Abstract: A lead electrode and a preparation method thereof are provided. The lead electrode includes an inner terminal, a lead, and an outer terminal, which are sequentially connected. The lead includes: an insulating substrate; an adhesive material coated on the insulating substrate, the adhesive material defining a trenched mesh; and a conductive material filled in the trenched mesh, wherein an angle formed by a grid line of the trenched mesh and a demolding direction is from 0° to 90°. Since the angle formed by the grid line and the demolding direction is very small, little adhesive material will be attached to the mold, such that the residues of the adhesive material are prevented.

  • 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.
