However, the manufacturing process temperature of the ITO thin film cannot be too high, so its impedance cannot be reduced to a very low level, so when a large-area ITO thin film is applied to a large-sized sensing device, the large-area ITO The impedance generated by the oxide film will not match its corresponding integrated circuit, and the high surface resistance will reduce the sensing sensitivity of the sensing device
Furthermore, the indium tin oxide film is brittle and prone to cracking when bent, which not only has a bad effect on its conductivity, but is also not suitable for flexible devices with flexibility.
In addition, indium is a rare material with high price, which is not conducive to cost control

Embodiment Construction
[0022] According to an embodiment of the present invention, in the conductive thin film structure, the thickness of the wire passing through the conductive mesh pattern is different from the design of the thickness of the conductive connection part, so that the wire and the conductive connection part have different light transmittance and reflectivity, thereby improving overall visibility. Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The same reference numerals are used in the drawings to designate the same or similar parts. It should be noted that the drawings have been simplified to clearly illustrate the content of the embodiments, and the detailed structures proposed in the embodiments are for illustration purposes only, and are not intended to limit the protection scope of the present invention. Those with ordinary knowledge can modify or change these structures according to the needs of actual implem...

Description
technical field [0001] The invention relates to a conductive film structure, and in particular to a conductive film structure with a conductive mesh pattern. Background technique [0002] In current main touch sensing devices, indium tin oxide (ITO) films are mostly used to make transparent conductive sensing layers. However, the manufacturing process temperature of the ITO thin film cannot be too high, so its impedance cannot be reduced to a very low level, so when a large-area ITO thin film is applied to a large-sized sensing device, the large-area ITO The impedance generated by the oxide film cannot match its corresponding integrated circuit, and the high surface resistance will reduce the sensing sensitivity of the sensing device. Furthermore, the indium tin oxide thin film is brittle and easily cracks when bent, which not only has a bad effect on its conductivity, but is also not suitable for application in flexible devices with flexibility. In addition, indium is a r...
