Embodiment Construction

[0026] The inventors found that, in the preparation process of the nano-silver wire touch panel, the nano-silver wire solution is usually directly coated on the substrate to form the nano-silver wire conductive layer. However, the silver nanowire conductive layers are only lapped together by weak intermolecular force. Therefore, the bonding strength between the nanosilver wire conductive layer and the substrate is poor, and it is easy to slip during the bending process, resulting in touch The phenomenon that the resistance of the panel is high and the resistance is unstable. Therefore, the inventor tried to coat an overcoating layer on the conductive layer of the silver nanowires. Usually, the overcoating layer is a transparent insulating adhesive layer, such as an optical adhesive layer. The coated overcoating layer can improve the conductive layer of the silver nanowires. The adhesion between the substrate and the substrate; however, the coating of the cover layer will reduc...

Abstract

The invention discloses a touch panel, a manufacturing method thereof, and a display device. The touch panel includes: a base, the base has a first area and a second area surrounding the first area; a wiring layer, located on the base of the second area; and a conductive layer, located on the base of the first area and directly covering Part of the wiring layer, the exposed wiring layer is used as the wiring lead-out area. The manufacturing method of the touch panel includes: providing a base, the base is divided into a first area and a second area surrounding the first area; forming a wiring layer, the wiring layer is located on the base of the second area; and forming a The conductive layer is located on the base of the first region and directly covers part of the wiring layer, and the exposed wiring layer is used as a wiring lead-out area. The touch panel and the manufacturing method of the touch panel of the present invention can not only improve the touch effect of the touch panel, but also realize the design requirement of a narrow frame, thereby satisfying the market demand for a narrow frame of a display device.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a touch panel, a manufacturing method of the touch panel, and a display device. Background technique [0002] Touch Panels have been used more and more in display technology fields such as tourist guide systems, ATMs, portable electronic products and industrial control systems because of their convenient use. The material of the touch electrodes of the traditional touch panel is usually indium tin oxide (ITO). However, the traditional ITO thin film limits its development to flexibility due to its own brittleness, conductivity and light transmittance. At present, the industry has been working on the development of alternative materials for ITO thin films. Among them, nano-metal wires have excellent mechanical properties, especially nano-silver wires have excellent electrical conductivity of silver. It has excellent light transmittance and flex resistance, so it can ...
