At present, according to media reports, LG has declared three screen patents to WIPO (World Intellectual Property Office) and appeared in the database. They are folding screen mobile phones designed by Z-Fold, folding-in and flipping-out mobile phones. In addition, a curly screen design patent was submitted to CNIPA (China National Intellectual Property Office). Thus, the global mobile phone manufacturers see the huge application prospects of flexible screens, follow the trend of development, catch up with the flexible display "Development Express", and seize the market place first.
In recent years, the concept of "flexible screen" has been in the uproar, but the real machine has not been seen. Some time ago, Samsung announced that it would launch folding screen mobile phones, but also repeatedly delayed the release time, because there are still unsolved problems in flexible technology.
Although there are endless stories about silver nanowires as ideal materials for large, flexible screens on the market, the complete physical screen has not yet been seen. On the market, the most promising flexible substitutes are carbon nanotubes, graphene, silver nanowires and metal grids. Among them, the best industrial application effect is silver nanowires and graphene. The scientific community has been looking for technical means to realize the market application of flexible screen materials.
Researchers combine graphene and nano silver wire to make conductive ink according to the proportion of formula, and use special coating technology to make composite flexible transparent conductive film to meet the diversification needs of flexible screen. Microcrystalline technology is one of the early high-tech companies focusing on new materials such as graphene and nano-silver wire. The flexible transparent conductive film has high conductivity, high transparency, high flexibility, rubbing resistance, etc. Good performance advantages meet the display needs of flexible screens.
With the update iteration of electronic terminal equipment, the future application market of flexible screen is very broad. With the unremitting efforts of scientific researchers, new material technology will be developed, and flexible screen will become the trend of social development.
