Samsung Techwin and researchers from the Seoul National University co-developed touch screen smartphone with a promising new material ‘graphene’ layer. They developed smartphones based on technology for mass production of graphene, paving the way for the commercial production of graphene, analysts said.
Samsung Techwin’s Research & Development (R&D) Center and the chemistrydepartment professor Hong Byung-hee and his researchers from Seoul National University noted Monday that they succeeded in applying touch screen made out of large-scale graphene film to Samsung’s smartphone ‘Galaxy.’ The research outcome was announced in the international academic journal in the nano field ‘ACS Nano.’
The latest research demonstrated the possibility of mass producing mobile phonesusing graphene, opening the way for graphene to be utilized in diverse areas including bendable displays and semiconductors.
The researchers adopted ‘Rapid Thermal CVD’ technology to produce graphene film. This technology saves time for mass production of graphene from 300 to 40 minutes, allowing for production of quality graphene with the size of 400×300㎟ at low temperatures.
The researchers created graphene film capitalizing on the RT CVD technology and then applied it to touch screen of Galaxy smartphones.
In the paper, the researchers explained, “our study confirmed that large-scale graphene film could be applied for smartphone production.”
