The first 15 inches graphene film was realized by us in China, transferred to PET substrate, and successfully applied to the flexible touch screen. Graphene touchscreen scale application will replace the current market-driven ITO touch screen, and as a key common technology for the next generation of human-computer interaction, leading the trend of intelligent terminals, push trillion leap in the development of electronic information industry.
