Embodiment Construction

[0035] The inventors found that the current manufacturing process of the nano-wire display device usually involves coating the nano-wire solution directly on the substrate to form a conductive layer of the nano-wire. However, due to the characteristics of the material and the process, the conductive layer of the nano-metal wire needs to be protected by coating with an adhesion-promoting layer, so that the conductive layer of the nano-metal wire adheres closely to the substrate. However, only some nano-metal wires can leak out of the adhesion-promoting layer and overlap with the signal connection layer. The overlapping area between the nano-metal wires and the signal connection layer is relatively small. It is necessary to increase the overlapping width of the nano-metal wire conductive layer and the signal connection layer, that is, increase the width of the frame.

[0036] Based on the above studies, an embodiment of the present invention proposes a method for preparing a con...

Abstract

The invention provides an electric-conduction overlapped structure, a preparation method thereof and a display device. After an electric-conduction layer is formed on a substrate, an opening is formedin the electric-conduction layer, nanometer metal wires in the nanometer metal wire electric-conduction layer can be more exposed out of the surface of a viscosity-increasing layer and make contact with a signal connecting layer, and at least part of the signal connecting layer is embedded into the opening in the thickness direction of the signal connecting layer; in this way, the lapping area ofthe signal connecting layer and the nanometer metal wire electric-conduction layer is increased further, impedance is reduced, conductivity is improved, accordingly, response time is shortened further, and even under the condition that the area of a border region is decreased, the conductivity can be guaranteed, and the requirement for designing a narrow border is met.

Description

technical field [0001] The invention relates to the technical field of touch screen preparation, in particular to a conductive laminated structure, a preparation method thereof, and a display device. Background technique [0002] With the rapid development of science and technology, it has gradually become a trend to develop and design technological products considering human factors. The display device (Touch Panel) has gained more and more applications in tourist guide systems, automatic teller machines, portable electronic products, and industrial control systems due to its convenient use. The display device locates the touched position by receiving the touch of a finger or a stylus, and then displays a desired image through the controller reading an instruction of the touched position. [0003] The material of the touch electrode of a traditional display device is usually indium tin oxide (ITO), which has high light transmittance and good electrical conductivity, but th...
