Abstract

The invention provides a transparent conductive film and a capacitive touch screen comprising the same. The transparent conductive film comprises a fingerprint affinity layer, a transparent substrate layer and ITO (indium tin oxide) layers, wherein the transparent substrate layer is arranged on the surface of the fingerprint affinity layer; the ITO layers comprise a first amorphous ITO layer, a crystalline ITO layer and a second amorphous ITO layer; the first amorphous ITO layer is arranged on the surface, far from the fingerprint affinity layer, of the transparent substrate layer; the crystalline ITO layer is arranged on the surface, far from the transparent substrate layer, of the first amorphous ITO layer; the second amorphous ITO layer is arranged on the surface, far from the first amorphous ITO layer, of the crystalline ITO layer. The transparent conductive film has the characteristics of better adherence, better anti-pollution performance and slip resistance, lower impedance, unapparent solid lines, lower cost and simple production process.

Description

technical field [0001] The present invention relates to the field of touch screens, in particular, to a transparent conductive film and a capacitive touch screen including the same. Background technique [0002] Adhesion refers to the adhesion of two adjacent layers. The larger the adhesion, the better the adhesion. The better adhesion between each layer in the capacitive touch screen ensures the normal operation of the capacitive touch screen and ensures that the capacitive touch screen has good adhesion. If the performance and adhesion are not good, the performance of the capacitive touch screen will be affected, resulting in the peeling off of the ITO layer, poor conductivity, and even failure to work properly. Therefore, the adhesion between the layers directly affects the performance of the capacitive touch screen. In particular, the adhesion between the ITO layer and its two adjacent layers has a greater impact on the performance of the capacitive touch screen. [000...
