Abstract

The invention relates to the field of touch screens, in particular to a flexible touch screen. The flexible touch screen comprises a flexible substrate, transparent conductive film and insulation adhesive film are attached to the flexible substrate, graphene / silver nanowire / graphene multi-layer composite thin film is adopted as the transparent conductive film to replace a traditional ITO electrode, and complete flexibility of the touch screen is achieved. Since the rigidity and water-oxygen insulation capacity of a traditional macromolecule substrate adopted by the flexible touch screen are lower than these of glass, the service life of the touch screen is easily shortened; the graphene / silver nanowire / graphene multi-layer composite thin film is adopted as an electrode and has extremely high rigidity and water-oxygen insulation capacity, the touch screen has high electric conductivity, and meanwhile the service life of the touch screen can be effectively prolonged. The prepared flexible touch screen is low in cost, good in performance and long in service life and can be bent randomly, the development of flexible display industries can be pushed, and the development requirements offuture flexibility industries are met.

Description

technical field [0001] The invention relates to the field of touch screens, in particular to a flexible touch screen. Background technique [0002] In the past few years, many electronic products such as mobile phones, tablet computers, wearable watches, etc. have been applied to the touch screen, which greatly facilitates the operation of customers. With the rapid popularization of touch-enabled consumer electronics products, the use of touch screens in the industry has grown significantly. As the application range of touch screens in the current market gradually expands, equipment manufacturers and suppliers realize that today's touch screens have limitations in supporting more demands for touch-enabled products. Chief among these is that existing touch sensors do not have the flexibility to be applied to curved surfaces, nor do they allow engineers to embed functionality across the entire flat surface of a touchscreen. [0003] The main factor limiting the flexibility o...
