Capacitance-type touch control sensor and capacitance-type touch control panel

Abstract

The invention discloses a capacitance-type touch control sensor and a capacitance-type touch control panel. The sensor comprises a plurality of first axis tracks, a plurality of second axis tracks, an insulation layer and a plurality of metal wires. Each first axis track includes a plurality of first axis sensing pads and a plurality of first connection lines, and each first connection line is in bridging connection with two correspondingly adjacent first axis sensing pads. Each second axis track comprises a plurality of second axis sensing measurement pads and a plurality of second connection lines, and each second connection line is in bridging connection with two correspondingly adjacent second axis sensing measurement pads. The first connection lines or the second connection lines are metal spray printing lines or the first connection lines and the second connection lines are all metal spray printing lines.

Problems solved by technology

[0003] In the prior art touch panel manufacturing process, the metal wires produced by screen printing or yellow light manufacturing process are easy to be observed by users due to their high visibility and affect the visual effect.

Although this shortcoming can be improved by narrowing the line width, the line width cannot be greatly narrowed due to the limitation of the manufacturing process.

In addition, the film thickness of the metal bridge structure produced by the general thin film yellow light production process is usually about 0.2um-0.3um. When the touch panel is testing the antistatic ability, it is easy to break at the bridge due to the high impedance of the metal wire

In addition, the method of forming the bridging line structure and wiring structure by using steps such as thin film, yellow light, and etching must go through multiple production processes, not only the related equipment is expensive, but also it is easy to cause waste of materials

Furthermore, if a plastic substrate is used as a transparent substrate, since the plastic substrate has poor tolerance to ultraviolet light and acid and alkali solutions, it is easy to damage the material properties during yellow light and etching processes, resulting in poor product quality. Rate
