Problems solved by technology

When the ITO impedance is large, it will be difficult to improve the signal transmission sensitivity of the touch sensing structure

[0004] The sensing electrode of another existing capacitive touch panel is a metal mesh sensing structure composed of a plurality of metal wires. Compared with ITO, the metal mesh sensing structure has lower impedance; however, in such a In the design, it is easy to interrupt the electrical connection of the sensing structure due to the disconnection of the metal wire in the manufacturing process, resulting in an open circuit

And when the double-layer mesh sensing structure is stacked, the mesh sensing structure of the upper layer and the lower layer overlap each other, causing the pattern at the overlapping position to become very obvious, which will cause the so-called "moire" visual defect , so as to affect the visual quality of the user's viewing
