In recent years, in addition to the "chip" is the "screen", these two components are responsible for the core performance and important viewing experience. In 2019, as the year of the explosion of new technologies, the rapid development of new technologies such as 5G commercialization, flexible display, VR AR, and so on, will make the screen of smart phones bigger and bigger to meet the diverse needs of human-computer interaction.
If the large screen of the smartphone is unchanged, it can be folded like a piece of paper, how convenient it is! Therefore, the new concept of "flexible display" has been proposed. In fact, the flexible display was proposed by scientists a long time ago, and took action, but the technology at the time was not able to achieve significant development.
Compared with traditional rigid screens, flexible screens are light and thin, have good flexibility, low energy consumption, and resistance to rubbing. They meet consumers' diverse deformation needs. Don't look at the coolness of the flexible screen, the internal structure is quite complicated. A small screen with more than 20 million flexible ultra-precision devices, 6 million-level flexible integrated circuits, and nearly a hundred kinds of micro-nano film materials. Devices, people have to lament the development of flexible screens is not easy. Today, flexible screens have become the products of future applications in many fields.
At present, the popular screen material on the market is ITO. Due to its shortcomings such as high square resistance, easy breakage and poor flexibility, it is difficult to meet the application requirements of flexible and large-sized touch screens. The implementation of 5G technology has led to the rapid implementation of human-computer interaction application scenarios, and future applications of flexible display can be expected. People urgently need to find flexible materials to replace traditional ITO materials.
In the area of new materials, there are only a handful of materials that meet the needs of conductive applications. At present, graphene, silver nanowires, carbon nanotubes, metal grids, etc. have good application effects. However, only graphene and nano-silver wires have been put into practical use and have good application effects.
The use of graphene and nano-silver wires, combined with a special transparent flexible conductive film, has strong advantages such as low square resistance, high light transmission, and good flexibility. The most important point is that the graphene and nano-silver wires used have a wide range of raw materials, low cost, and reduce production costs. If a flexible transparent conductive film is applied to a capacitor of a flexible screen, the flexible display of the product is realized as a reflection of scientific and technological progress.
Over time, the production technology of graphene and nano-silver wires has gradually matured, and now many Chinese companies have realized mass production of graphene and nano-silver wires. In the future, new materials such as graphene and nano-silver wires will have more applications in production and life. We look forward to this day!
