With the diversified development of global smart terminals and the advancement of science and technology, manufacturers must base their technological innovation on meeting the changing needs of consumers. At present, the demand for high-end displays in the market is increasing. Flexible displays have become a hotspot in the international high-tech field. Its strong plasticity allows flexible screens to be used in displays in a variety of scenarios.
Recently, the voice of the mobile phone industry about the new generation of folding screen mobile phones is getting higher and higher. Major global mobile phone manufacturers are accelerating the pace of research and development of folding screen mobile phones to occupy the flexible folding market first. With the popularization of flexible products, the disadvantages of traditional ITO conductive materials are gradually exposed, lacking flexibility and resistance to bending, unable to make flexible panels, restricting the development of flexible displays, and thus leading to the replacement of nanosilver, a new material. line.
Some people may wonder why graphene has good light transmission and low square resistance, so why can't it be a substitute for flexible folding materials? Graphene has not yet achieved large-scale mass production for the time being, and the conductivity of thin film products made of it has not yet reached market requirements. From various aspects, nano-silver wires are expected to replace ITO conductive materials and have outstanding advantages in the field of flexible screen applications.
1. Silver nanometer online and downstream industries have matured
Industry insiders point out that nano-silver wires are used as touch materials instead of ITO and metal grids. From the perspective of commercially available products, the flexible foldable touch products and large-sized touch products produced using nano-silver wire technology have been relatively mature in the degree of cooperation in the upstream and downstream industry chains, and can cope with future product outbreaks in the market.
2. Solving the constraints of silver nanowires
With the increase of the amount of silver wire, the conductive film of silver nanowires has a higher haze of the finished product, which cannot be used as an ITO conductive film to remove the etched matte layer, thus limiting its application in the small size field. Only suitable for large or flexible products. Small-size display products account for 70% of the entire touch-sensitive products, and large-scale displays have competition such as metal grids, resulting in poor market performance.
In response to this problem, related companies have come up with solutions to reduce haze, such as reducing the diameter of silver nanoabsorption, reducing the size effect of nanometers, and many other ways to achieve the goal of reducing haze.
Silver nanowires are the most promising alternative materials for ITO. After solving the constraints, they will give full play to their performance advantages, realize mass production, and become the key material for flexible product manufacturing. Flexible touch screens based on silver nanowires will usher in unprecedented development opportunity.
