Abstract
The invention relates to a transparent conductive thin film, comprising a first hard coating, a first transparent conductive layer and a first metal layer which are sequentially formed on a first surface of a base material, and a second hard coating, a second transparent conductive layer and a second metal layer which are sequentially formed on a second surface of the base material. The non-planarstructures of the surfaces of the first hard coating and / or the second hard coating can enable the surfaces of the first metal layer and / or the second metal layer to form surface embossed structures.The surface embossed structures and the non-planar structures are of the same surface structure. Thus, the surface embossed structures can enable the two adjacent metal layers to form point contact,so as to prevent the metal layers from adhering to each other. When producing the transparent conductive thin film, the non-planar structures just need to be formed on the surfaces of the first hard coating and / or the second hard coating in an embossing manner without performing operations of adding particles and the like. Therefore, the production efficiency of the transparent conductive thin film is effectively improved. In addition, the invention further provides a touch screen and a preparation method thereof.
Description
technical field [0001] The invention relates to the technical field of capacitive touch screens, in particular to a transparent conductive film, a touch screen and a preparation method thereof. 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. At present, compared with crystalline polymer films, amorphous polymer films have the advantages of less birefringence and uniformity, so most transparent conductive films use amorphous polymer films as substrates. [0003] Amorphous polymer films are more fragile than crystalline polymer films, and their surfaces are more susceptible to damage. When the transparent conductive film is rolled in...
