Touch panel and manufacturing method thereof

Abstract

The invention relates to information input technology, in particular to a touch panel and a manufacturing method thereof. The touch panel comprises a substrate and an electrode layer. The electrode layer is formed on the substrate and comprises a plurality of parallel X-axis traces, a plurality of parallel Y-axis traces, a plurality of bridge structures and a plurality of insulation blocks. The plurality of X-axis traces intersect with the plurality of Y-axis traces, and the plurality of Y-axis traces are partitioned into a plurality of units by the plurality of X-axis trances. The bridge structures are positioned at intersections of the X-axis traces and the Y-axis traces and are used for connecting adjacent two units which are positioned on the two sides of the same X-axis trace and belong to the same Y-axis trace. The bridge structures are formed on the substrate; the insulation blocks are arranged on the bridge structures; the overlapped parts of the X-axis traces and the bridge structures are positioned on the insulation blocks; and the X-axis traces are insulated from the bridge structures through the insulation blocks. A manufacturing material and a process of the bridge structures are the same as the manufacturing material and the process of the X-axis traces and the Y-axis traces.

Description

technical field [0001] The invention relates to an information input technology, in particular to a touch panel for information input and a manufacturing method thereof. Background technique [0002] The emergence of touch technology makes information input methods not limited to traditional keyboard and mouse. In recent years, due to the use of touch input technology, the positions originally used to make traditional keyboards or input keys in electronic devices can be used to make screen display areas, so that electronic devices have wider and larger screens for displaying text, pictures, etc. , video and other information, and then the touch technology has achieved rapid development. At present, touch panels are widely used in people's daily life. Among them, touch panels are typically used in mobile phones, music video players (MP3 / MP4, etc.), personal digital assistants, global positioning systems (GPS), social public In the navigation systems of service agencies and ...

Problems solved by technology

[0012] However, the single-sided single-layer capacitive touch panel 40 includes a metal bridge 42, and the metal bridge 42 needs to be formed between two adjacent units 41X of the X-axis trace 41a through an additional process, and the The processing technology of the metal bridge 42 is different from the processing technology between the X-axis track 41a and the Y-axis track 41b. Therefore, it is necessary to make the metal bridge 42 through professional equipment and materials, which not only increases the process, but also reduces the production efficiency, but also increases the production cost of the capacitive touch panel 40
