Problems solved by technology

[0003] The transparent conductive film is a sensing element in the touch screen that receives input signals such as touch. At present, the indium tin oxide layer (hereinafter referred to as the ITO layer) is a crucial component of the transparent conductive film. Although the manufacturing technology of the touch screen is developing rapidly, However, taking the projected capacitive screen as an example, the basic manufacturing process of the ITO layer has not changed much in recent years. It is always inevitable to need ITO coating and ITO patterning.
[0004] Indium is an expensive metal material, so using ITO as the material of the conduct

Abstract

The invention provides a transparent conducting film, which comprises a substrate, a first conducting layer and a first lead electrode, wherein an inducing area and a lead area which is positioned on the edge of the inducing area are arranged on one surface of the substrate; the first conducting layer comprises grid-shaped first conducting patterns, the first conducting patterns are configured at the inducing area and the lead area and are mutually connected, and the first conducting patterns are formed by conducting wires; the first lead electrode is configured at the lead area, and the first lead electrode is electrically connected with the first conducting layer; the width of the conducting wires of the first conducting patterns which are positioned at the inducing area is smaller than that of the conducting wires of the first conducting patterns which are positioned at the lead area. According to the transparent conducting film provided by the invention, the width of the grid lines at the inducing area, i.e. a visual area is smaller than that of the grid lines at the lead area, i.e. a non-visual area; thus, when the first lead electrode is connected with the grid lines of the non-visual area, the conducting performance is greatly enhanced.
