There has been a major breakthrough in the development of transparent mobile phone technology. Stanford University has recently made every effort to develop silicon-based nanowire technology; nanowires are extremely slim, beyond the range detectable by the human eye, not only can they store large amounts of electrical energy, but also generate new generations of high-energy nano batteries, or The formation of a transparent electrode network to realize the transparent design of mobile phone batteries and screen components will help speed up the launch of the new generation of transparent mobile phones.
Yi Cui, a lifelong professor at the Department of Materials Science and Engineering at Stanford University, said that nanowire and carbon nanotube technology will create a new era in lithium battery design. The introduction of nanowires and carbon nanotubes in the silicon architecture can greatly increase energy by ten times. Storage efficiency, which can reduce the size of the battery and extend the use time; even through printing (PrinTIng) and other processes, nanowires can be plated on polydimethylsiloxane (PDMS) film to develop fully transparent liquid crystal Display (LCD), organic light-emitting diode (OLED) screen.
It is reported that Stanford University is actively developing technical cooperation with the industry. It is expected that nanowires will be used in mobile device lithium battery design in the next 1 to 2 years to extend the average endurance of existing devices and reduce battery space; In addition, because the nanowires can achieve a width of less than 50 microns (μm), which is beyond the human readable range (50 to 100 microns), it also helps to make the design of mobile phone batteries and panel components transparent, allowing terminal brand manufacturers to develop More dazzling next-generation smartphones.
Because batteries and screens account for the largest proportion of mobile phone volume, they are the two key links to achieving transparent design. Cui believes that, based on the research progress of Stanford University, the current use of nanowires to manufacture lithium batteries and transparent electrode technology for touch modules are both It is already in place, and due to its compatibility with the semiconductor manufacturing process, it is expected to quickly optimize costs in the future and promote the mass production of related solutions. However, at this stage, the mainstream LCD screen of mobile phones needs time to work towards full transparency. The main reason is that the panel structure is complex and requires a backlight mechanism, which will raise the technology threshold of peripheral components. In contrast, the active light-emitting AMOLED panel is expected to be the first Transparent design.
In addition to being the promoter of transparent mobile phones, nanotechnology can also charge paper, textiles and sponges, and promote more advanced biomedical equipment, subverting the entire technology industry. Cui emphasized that when new materials such as carbon nanotubes and nanowires are introduced into non-conductors such as paper and textiles, they can be transformed into new types of electrical conductors, which can create more diverse scenarios for power storage and utilization. 5 Within 10 years, nanotechnology will enter the field of energy applications. In addition, nanofilter technology also helps to create the next generation of nano-level medical equipment, which can eliminate pathogens in a cheaper and more efficient way, replacing existing ultraviolet (UV) and chemical disinfection systems.
