Touch screen, as one of the most expensive components in mobile phone components, is an important reason for the price of mobile phones. Once the mobile phone screen is damaged, users need to bear higher maintenance costs. If there are new materials that can be replaced, the raw material production cost of the touch screen is reduced, and at the same time, it has excellent flexibility to protect people from the pain of broken screens.
The common touch screen raw material on the market is ITO. The material is expensive, and its conductivity and transparency are the main reasons for its application. With economic development and technological progress, the rigidity and brittleness of traditional ITO materials are difficult to meet people's diverse consumer needs.
With the advent of folding screen mobile phones, mobile phone touch screens have gradually shifted to the flexible direction. British researchers have found that mixed electrodes made of graphene and nano-silver wires have the potential to make touch screens. The biggest advantages are low production costs and excellent optical and electrical characteristics to meet the needs of touch screen mobile phones. Graphene is a two-dimensional nanomaterial that is only one atom thick, and has excellent electrical conductivity; the width of nano-silver wires is only one ten thousandth that of hair, and the transparency of the film is good. The combination of graphene and nano-silver wire can form a conductive, transparent and flexible thin film.
Scientists spend a lot of time researching non-fragile touch screen materials, and the advent of new technologies has turned ideas into reality. The reason why graphene and nano-silver wire materials have not entered a large number of commercial stages is that the problem of the activation of nano-materials has not been solved well.
After a long period of development, breakthroughs in new nano-silver wire materials technology have made various products using nano-silver wires as raw materials to appear in the touch display industry, which has become the most closely integrated new material development direction of the touch display industry.
In fact, nano-silver wire technology is still undergoing continuous optimization and development, and its optical and electrical properties far exceed the new basic conductive materials of ITO materials. The low resistance value and high ductility of the nano-silver wire electrode material can enable the current touch display products to get rid of the space constraints of flat-panel display, and develop various touch display products such as curved surfaces and folds to achieve touch display. The omnipresent industry vision.
The research and development and application of graphene and nano-silver wire new materials are the embodiment of scientific and technological development. As the economic level improves, the diversified demands of consumers have led to the emergence of new products. With the continuous breakthrough of new material technology, it will be applied to all aspects of human life in the future.
