Problems solved by technology

[0004] However, the above capacitive touch screen structure has the following disadvantages: (1) The reflectivity of the ITO layer and the metal bridge is not the same, when this touch screen is exposed to strong light (such as under sunlight), people can see Brighter metal bridges and darker ITO layers affect aesthetics
(2) Since the metal bridge needs to separate the first axis trace from the second axis trace, during the production process, ITO is easy to break and thus lowers the yield; moreover, it is also easy for the user to touch the conductive circuit of ITO during the long-term touch process. Press off, resulting in touch failure

Abstract

The invention discloses a capacitive touch panel and a manufacture method thereof. The touch panel comprises a glass substrate provided with a first face and a second face, a first transparent conductive layer arranged in the middle of the first face of the glass substrate, a second transparent conductive layer arranged in the middle of the second face of the glass substrate, a conductive metal layer arranged on the periphery of the first face of the glass substrate and two insulation layers arranged on the first transparent conductive layer and the second transparent conductively layer. By means of the technical scheme, the first transparent conductive layer and the second transparent conductive layer are respectively arranged on two faces of the glass substrate, and the transparent conductive layers are smooth in surface and not easy to break in press mode. Therefore, the touch panel is long in service life, cannot have strong reflection phenomena under strong light and achieves the effect of attractive appearance.

Description

technical field [0001] The invention relates to a touch panel, in particular to a capacitive touch panel and a manufacturing method thereof. Background technique [0002] With the development of science and technology, touch screens have appeared in many areas of people's lives, such as medical equipment, mobile and handheld devices, industrial process control, and office automation. According to the working principle, touch screens can be divided into resistive touch screens, capacitive touch screens, surface acoustic wave touch screens and infrared touch screens. Among them, the capacitive touch screen has the widest range of applications. [0003] Chinese patent application publication CN101441545 discloses a capacitive touch screen and a manufacturing method thereof. The capacitive touch screen includes a substrate, and also includes an ITO layer, an insulating layer, a circuit layer and a protective layer arranged on the same side of the substrate. The ITO layer consi...
