At the MWC exhibition hosted by Huawei, the first 5G mobile phone, the Mate X, was announced for the first time. Among them, what attracted the attention of electronic fans was its folding screen. The emergence of folding screen mobile phones has provided an opportunity for the internal structural materials to gradually shift to the direction of flexibility, and at the same time pushed the development of touch screens towards the field of flexibility.
At present, traditional ITO materials can no longer meet the diversified needs of consumers. Therefore, conductive materials such as flexible metal grids, nano silver wires, carbon nanotubes, and graphene have emerged in the electronic component industry. In fact, nano-silver wires and metal grids can be put into industrial applications with good results.
Compared with other flexible materials, nano silver wire has excellent performance. In addition, the nano-silver wire also has excellent electrical conductivity, excellent light transmission, and resistance to flexion, making it better applicable in the field of touch screens.
With the continuous discovery of conductive film materials, coupled with new process innovations, nano-silver conductive films have the advantages of simple production process, low cost, and good stability, and are the first to take the lead in other new conductive film materials. So what is nano silver? Nanosilver is usually synthesized in solution, and the obtained ink is coated to obtain transparent conductive films with different square resistances. The transparent conductive film produced by nano-silver wire is the best solution for the development of flexible touch to a foldable and curved screen.
With the continuous emergence of scientific and technological innovation achievements and rapid technological development, electronic equipment manufacturers must base their technological innovation on accelerating industrial transformation and upgrading to meet the rapidly changing global market demand. According to data from research institutes, global shipments of flexible screens will rise to 792 million yuan in 2020. It can be seen from the data that the application prospect of the flexible screen market is huge.
The nano-silver wire, which is the raw material for the manufacture of flexible screens, is bound to have broad development prospects. At present, many companies have laid out research and development of nano-silver wires, and Microcrystalline Technology is one of them. Graphene-nano-silver wire composite flexible transparent conductive films have been successfully developed. It is currently the most potential material to replace ITO. In the near future, downstream products can be seen on the market.
