Abstract

The invention provides a transparent conductive film and a capacitive touch screen comprising the same. The transparent conductive film comprises a transparent substrate layer and ITO (indium tin oxide) layers arranged on the surface of the transparent substrate layer, wherein 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 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 unapparent solid lines, lower impedance, lower cost and simpler production process; meanwhile, the ITO layers have good adherence with the transparent substrate layer and a silver or copper conductive printing layer in a follow-up process, so that good performance of the transparent conductive film is guaranteed, and the continuity of processes for production is improved.

Description

technical field [0001] The invention relates to the field of touch screens, in particular to a transparent conductive film and a capacitive touch screen comprising it. Background technique [0002] Adhesion refers to the adhesion of two adjacent layers. The greater the adhesion, the better the adhesion between the layers in the capacitive touch screen ensures the normal operation of the capacitive touch screen and the good performance of the capacitive touch screen. If the performance and adhesion are not good, the performance of the capacitive touch screen will be affected, resulting in the peeling of the ITO layer, poor conductivity, and even failure to work normally. Therefore, the adhesion between the various layers directly affects the performance of the capacitive touch screen, especially It is the adhesion between the ITO layer and its adjacent two layers that has a greater impact on the performance of the capacitive touch screen. [0003] The ITO layer in the capaci...
