Problems solved by technology

[0002] ITO (indium tin oxide) conductive film is an important raw material for making capacitive touch screens. The traditional film structure multi-touch touch screen generally has a GFF structure (Glass-Film-Film, the sensing layer and the driving layer of the touch screen are located in two layers respectively. On the conductive film), GF2 (Glass-Film, the driving layer and the sensing layer of the touch screen are located on the upper and lower sides of the single-layer conductive film) structure, but the GF2 structure manufacturing process is relatively complicated, and the technical threshold is high, so most of the touch terminals on the market The film structure touch screen of the product is generally GFF structure
[0003] However, with the rapid development of consumer electronics, entertainment games, wearable and foldable products, smart homes, education and teaching and other fields, the demand for touch panels or flexible panels of various sizes is becoming more and more urgent, and the above-mentioned traditional ITO conductive film cannot be realized. For 3D curved surface applications, the conductivity cannot meet the requirements of medium and large size touch panels, and ITO is a scarce resource and is not renewable
