Embodiment Construction

[0026] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0027] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

Abstract

The invention relates to a transparent conductive thin film, which comprises a base material, a transparent conductive layer and a metal composite layer, wherein the metal composite layer comprises ametal conductive layer, and a first metallic oxide layer and a second metallic oxide layer attached to both sides of the metal conductive layer. When the transparent conductive thin film is applied toa touch screen, the metal conductive layer is a portion that forms a lead wire. Since the metallic oxide has higher roughness than that of the metal conductive layer, the second metallic oxide layercan have an effect of improving the adhesion of the metal composite layer. Further, the first metallic oxide layer and the second metallic oxide layer can protect the intermediate metal conductive layer. On the one hand, the water vapor of the inner and outer layers can be isolated to prevent the intermediate metal conductive layer from being oxidized; on the other hand, the metal conductive layercan be mechanically protected from scratches. Therefore, the transparent conductive thin film can effectively avoid the wear of the metal conductive layer, thereby facilitating the improvement of theyield of touch screen products. In addition, the invention further provides the touch screen.

Description

technical field [0001] The invention relates to the technical field of capacitive touch screens, in particular to a transparent conductive film and a touch screen. Background technique [0002] Transparent conductive films are the core components of capacitive touch screens. With the rapid development of smart terminals, the demand for transparent conductive films is also increasing. The transparent conductive film generally includes a base material and a hard coat layer, a conductive layer and a metal layer disposed on both sides of the base material. [0003] When applying transparent conductive films to touch panels, the metal layer is used for etching to form leads. In the process of transparent conductive film processing, the process of large sheet and whole surface processing is generally adopted, so the formed transparent conductive film needs to go through multiple processes such as winding, transportation, storage, and cutting before being applied to the touch scr...
