The film size is of great significant for graphene in various electronics related applications such as touch panels, OLED, displays and so on.In this talk, I will give a brief introduction of graphene film manufacturing technology at Chongqing Graphene Technology Co.Ltd., and show how we can get graphene film size up to 1m by 1m for industrial application.After that, I will focused on the processes of how we make a capacitive touch panel and integrate it into a smart phone.
