Embodiment Construction

[0026] The inventors found that, in the preparation process of silver nano wire touch panel, the silver nano wire solution is usually directly coated on the substrate to form the silver nano wire conductive layer. However, the conductive layer of silver nano wires is only lapped together by weak intermolecular forces. Therefore, the bonding strength between the conductive layer of silver nano wires and the substrate is poor, and it is easy to slip during the bending process. The resistance of the panel is high and the resistance is unstable. Therefore, the inventor tries to coat an overcoat on the conductive layer of silver nanowires. Usually, the overcoat is a transparent insulating adhesive layer, such as an optical adhesive layer. The coated overcoat can improve the conductive layer of silver nanowires. Adhesion between the substrate; however, the coated cover layer will reduce the effective contact area between the conductive layer of nano-silver wire and the wiring layer ...

Abstract

The invention discloses a touch panel, a fabrication method of the touch panel, and a display apparatus. The touch panel comprises a substrate having a first region and a second region surrounding thefirst region, a routing layer located on the substrate of the second region, and a conductive layer located on the substrate of the first region and directly covering part of the routing layer, wherein the exposed routing layer serves as a routing lead-out region. The fabrication method of the touch panel comprises the steps of providing the substrate, wherein the substrate is divided into the first region and the second region surrounding the first region; forming the routing layer, wherein the routing layer is located on the substrate of the second region; and forming the conductive layer,wherein the conductive layer is located on the substrate of the first region and directly covers part of the routing layer, and the exposed routing layer serves as the routing lead-out region. According to the touch panel and the fabrication method of the touch panel, the touch effect of the touch panel can be improved and the design demand of a narrow bezel can be met, so that the market demand of the narrow bezel of the display apparatus is met.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a touch panel, a manufacturing method of the touch panel and a display device. Background technique [0002] The touch panel (Touch Panel) has gained more and more applications in display technology fields such as tourist guide systems, automatic teller machines, portable electronic products, and industrial control systems because of its convenient use. The material of the touch electrode of the traditional touch panel is usually indium tin oxide (ITO). However, the development of the flexibility of the traditional ITO film is limited due to its own brittleness, conductivity and light transmittance. At present, the industry has been working on the development of alternative materials for ITO films. Among them, nano-metal wires have excellent mechanical properties, especially nano-silver wires have excellent conductivity of silver, and at the same time due to their nano-s...
