Graphene in mobile displays


    Most touch screens on the market today use ITO for their transparent electrodes. ITO, however, is quite problematic as its rare, expensive, brittle and unsuitable for flexible displays so replacements are constantly being searched for.Graphene is one of the most promising materials in the run for ITO replacements, and China even has touchscreens on the market that contain graphene electrodes.

    Compared to silver-based solutions, graphene holds optical properties that make it especially desirable for such applications. Chinese company Powerbooster developed graphene-based flexible touch panels for mobile devices. The company says that graphene is cheaper and stronger than ITO and it plans to invest $150 million in the next three years in order to bring their solutions to the market.

    China’s Chongqing Morsh Technology is building a production line in Chongqing that will be used to produce 15″ single-layer graphene films. They hope to start production soon and they’ve already signed an agreement with Guangdong Zhengyang, an OGS maker to produce 10 million graphene based transparent conducting films (TCFs) in a year for the next five years. These films will be used to produce touch panels for mobile devices.
