Problems solved by technology

When the line width and line space of the fan-out wire are too large, the area of ​​the surrounding area will increase, which does not meet the design requirements of the slim border.
However, if the width of the fan-out wires continues to be reduced and the pitch is too small, the resistance of the fan-out wires will increase, thereby affecting the sensing sensitivity of the touch panel

Abstract

A touch panel and a manufacturing method thereof. The touch panel comprises a substrate, a touch circuit and a plurality of fan-out wires; wherein, the substrate has a touch area and a peripheral area adjacent to the touch area; the touch circuit is arranged at the touch area of the substrate; the fan-out wires are arranged on the peripheral area of the substrate and are electrically connected with the touch circuit; the fan-out wire comprises a first wire, a first dielectric layer and a second wire; the first wire is arranged on the peripheral area of the substrate, the first dielectric layer is arranged on the peripheral area of the substrate for covering the first wire and has at least one contact window arranged over the first wire, the second wire is arranged on the first dielectric layer, the first wire and the second wire in the same fan-out wire are electrically connected with each other through the contact window, and have the substantially same pattern.

Description

technical field [0001] The present invention relates to a touch panel and a manufacturing method thereof, and in particular to an Added-on touch panel and a manufacturing method thereof. Background technique [0002] In recent years, the technology of digital information and wireless mobile communication has developed rapidly. In order to achieve the purpose of portability, lightweight and user-friendly operation, many electronic information products, such as mobile phones (Mobile Phone), handheld computers (Handheld PC), personal digital assistants (Personal Digital Assistance, PDA) or smart Mobile phones (Smart Phone), etc., the input method has changed from traditional keyboard or mouse to using a touch panel (Touch Panel) as an input device. In addition to convenience, it has become a very popular new type of human-machine interface and multimedia interaction method due to its intuitive operation, so it has received considerable attention and a lot of development.
