The world’s first graphene-based electronic paper for use in both hard and flexible displays for electronic devices has been developed in China.

Electronic paper display company Guangzhou OED Technologies announced it has developed the graphene-based e-paper, which it described as being more pliable and having higher light transmittance than existing types of e-paper.

As a result, graphene-based displays would be brighter but also cheaper, as graphene is based on the abundant element carbon, the firm said. Conventional e-paper is made of the rather costly rare metal indium.
