News from November 11, 2020, Beijing time, why is the nano-silver wire capacitive screen the best choice for large-size touch screens? As screens become larger and more flexible, traditional ITO materials can no longer meet the diversified needs of the market, and their essential problems such as conductivity and light transmittance are not easy to overcome. Therefore, manufacturers have begun to seek alternatives to ITO materials, such as metal grids, Graphene and nano-silver are all touch materials that have emerged in recent years, and they are believed to replace ITO materials in the future.
In theory, the conductivity, light transmittance, ductility and other properties of these materials are superior to ITO, but due to the characteristics of the first two materials and technical limitations, no major breakthrough has been made, such as metal grids. It is copper plating on PET film, and metal grid pattern is formed by wet etching process. It is applied to large-size screens. The line width is usually above 8-10um. It is easy to produce Moire interference ripples and grid patterns, which is not suitable for observation distance. A relatively recent display screen; while graphene is still in the technological concept stage, and the progress of industrialization has not yet made a substantial breakthrough.
After many repeated experiments, it has been proved that the nano silver wire has excellent characteristics such as strong conductivity, high light transmittance, low haze, low resistance value, and bending resistance. It is suitable for flexible, bendable, and large-size touch sensing materials. The best choice, so it is praised by the industry as the best substitute for current ITO materials.
Huake Chuangzhi is one of the earliest teams specializing in the research and development of silver nanowire technology in the world, and it is also the first national high-tech enterprise in China that has successfully applied silver nanowires in the field of large-size capacitive screens and achieved industrialization. In addition to the complete independent intellectual property rights of the nano-silver industry upstream to downstream, the nano-silver wire capacitive screen produced by Huake Chuangzhi has been widely used due to its quality and cost advantages.
From the process point of view, Huake Chuangzhi's nano silver wire capacitive screen uses a nano silver conductive film prepared by a roll-to-roll wet coating precision process. The coating speed is fast and the film uniformity is good. After curing, its When the light transmittance reaches more than 90 percent , the surface resistance can be less than 10Ω/port, and it is presented to the terminal application, the screen effect is better, and the touch response is more sensitive.
The black frame of large screens on the market has a width of 30mm. In terms of design, our company has introduced a single-sided nano-silver wire capacitive touch film. The frame has been successfully made to 10mm to achieve an ultra-narrow frame. When applied to the whole machine, the appearance looks Higher-end and more fashionable.
From the perspective of cost, Huake Chuangzhi's double-sided nano silver transparent conductive layer solution can prepare double-layer circuits on a single-layer film, and use one less layer of PET material and one layer of OCA material, which effectively reduces the cost of touch modules and meets the needs of electronics. The market trend of thin and light products.
High-performance large-size capacitive touch technology can better meet the needs of the market. Huake Chuangzhi is the earliest manufacturer of 65-, 75-, and 86-inch nano silver touch display modules in China, including 65-inch, 75-inch and 86-inch The series of touch modules are shipped in large quantities and have been fully tested by the market, laying a solid foundation for the larger-size product market. With the breakthrough and continuous improvement of Huake Chuangzhi's nano silver capacitive touch technology, the expansion of related projects and the increase in production capacity will inevitably reduce costs. This will bring new changes to the interactive mode of the large-size market, and it is expected to eventually achieve a full replacement. .
