OLED technology is spiked?
According to foreign media reports, scientists have combined silver and graphene to develop a screen material that is more friendly to the environment and more flexible. Compared with current mobile phone screens, the cost is greatly reduced. At the same time, this new method will use less energy, more sensitive equipment in production, and will not be damaged in the air environment, and the indium tin oxide currently used to make smart phones is very fragile and expensive.
Indium in indium tin oxide is a rare metal, which is not only expensive but also has a destructive effect on the environment in terms of ecology. The current best alternative is silver. Although silver will not cause damage to the ecology, prices are still not low. Scientists from the University of Sussex in England combined silver nanowires with graphene to form a binary carbon material. This hybrid material has the same performance as the former, and the cost is also reduced a lot.
Graphene Although silver nanowires have been used in touch screen technology, no one has ever tried to use it with graphene before. This is a new way of material combination. We let the graphene particles float on the water surface, then collect it with special tools and place it on top of the silver nanowires so that we can form any pattern we like.
This groundbreaking technology is inherently malleable. In this way, the combination of silver nanowires and graphene is very simple, and it can be achieved by simply using a spray and a patterned roller. Researchers said that this technology may cause the power consumption of mobile phone screens to be a thing of the past. Dalton thinks that adding graphite ** to the silver nanowire grid can increase the electrical conductivity by about 10,000 times.
Silver nanowires According to Matthew Large, a researcher at the University of Sussex, “This means that only a small part of silver can achieve the same effect, and even the effect may be better. This also makes the equipment that uses this kind of screen more sensitive. The power consumption is even lower.Although silver is also a rare metal, with this technology, only a small amount of silver is needed, while graphite** is produced from natural graphite. Natural graphite reserves in nature are abundant, so the cost is also high. It will drop sharply.†Large also said that at present, even if repeated bending, its conductivity will not change, which means that this screen can be used as a flexible screen, while its price is relatively low.
Comments: Although this screen's excellent performance can not be underestimated, but at present, this screen is still only in the laboratory, everything still stays in the concept, in order to really challenge the OLED I am afraid there is a long way To go.
