A capacitive touch screen with high-strength explosion-proof performance and a jumper structure

Abstract

The invention provides a capacitive touch screen with high-strength anti-explosion performance and a jumper structure. The screen comprises a glass cover plate, a flexible baseplate, a transparent electric conduction film layer and the jumper structure disposed on the transparent electric conduction film layer, wherein the transparent electric conduction film layer is formed on the flexible baseplate, and two adjacent first direction sensing units are connected by a connecting block; the jumper structure is disposed two adjacent second direction sensing units, and spans the two adjacent first direction sensing units; the jumper structure comprises a first electric conduction film layer, a second electric conduction film layer and a third electric conduction film layer, the middle part of the first electric conduction film layer is attached on an insulating layer, and the first electric conduction film layer is made of Mo-Nb alloy; the first electric conduction film layer is covered by the second electric conduction film layer, and the second electric conduction film layer is made of Al-Nd alloy; and the second electric conduction film layer is covered by the third electric conduction film layer. According to the invention, electric conduction and touch performance of the capacitive touch screen could be effectively improved; short-circuit cases could be avoided; and use experience could be improved.

[0002] The single-layer multi-point capacitive touch screen is the latest design in the capacitive screen industry. This design reduces the use of materials and significantly reduces the thickness of the product, which meets the development needs of electronic products that are light, thin, and functionally diverse; The structure is made through the process of etching the ITO film, printing the insulating layer, and printing the conductive silver paste. It is necessary to open a large opening in the insulating layer at the "node" position to facilitate the penetration of the conductive silver paste of the upper silver paste conductive line and the lower ITO. The conductive layer is connected and conducted. In this way, there is no contact or poor contact between the silver paste and the ITO conductive layer, forming an open circuit; in addition, because the opening of the insulating layer is large, it is easy to cause the conductive silver paste and the ITO conductive layer to be biased due to printing. bit causes a short circuit between the ITO conductive layers
