A thin film laminated structure and a manufacturing method thereof

Abstract

The invention discloses a thin film laminated structure and a manufacturing method thereof. The manufacturing method comprises the following steps: providing a substrate, and forming a groove in the substrate; forming a tackifying layer on the inner wall of the groove; forming a nano metal wire layer in a groove of the substrate; forming a protective layer on the substrate. In the thin film laminated structure and the manufacturing method thereof, the nano metal wire layer is no longer simply coated on the substrate, but filled in the groove on the substrate, thereby increasing the contact area between the nano metal wire layer and the substrate and improving the adhesion between the nano metal wire layer and the substrate; an adhesion-enhancing layer is arranged between the nano-metal wire layer and the substrate, which further enhances the adhesion between the nano-metal wire layer and the substrate, and reduces the possibility of the nano-metal wire layer moving when the substrate is bent; the protective layer is also formed on the substrate to fix the silver nanowire layer on the substrate, further reducing the possibility of the nanowire layer moving when the substrate is bent, and protecting the nanowire layer from external environmental influences such as corrosion and wear.

Description

technical field [0001] The present invention relates to the technical field of touch screens, in particular to a thin film laminated structure and a manufacturing method of the thin film laminated structure. Background technique [0002] Touch screen (full name in English is Touch Panel), also known as touch screen and touch panel, is a device formed on the display surface of an image display device and using conductors such as human body or capacitive pen to input commands, which can replace the mouse, keyboard, etc. Input devices such as external input devices and mechanical input keys can effectively simplify the structure of electronic products such as computers and mobile phones, and have very broad application prospects. [0003] The touch screen includes a substrate and a touch structure formed on the substrate. The touch position is sensed by the capacitance change of the touch structure. The touch structure includes two pairs of touch electrodes, which are commonly ...

AI Technical Summary

Problems solved by technology

Among them, TX or RX includes several metal wires and transparent electrodes stacked, and the commonly used transparent electrode is ITO (indium tin oxide). With the popularization of flexible display products, the disadvantages of ITO are gradually exposed: due to its large resistance, The problems of high cost and poor damage resistance limit the development of flexible touch screens

[0004] Based on the above factors, in recent years, it has become a trend to replace ITO with nano-metal wires such as nano-silver wires that have outstanding performance in terms of conductivity, light transmittance, and bendability. Problems, such as the poor adhesion of nano-silver wires to the substrate, and the nano-silver wires are prone to movement when the flexible substrate is bent
