France based Genes'Ink launched a new silver-based solvent conductive ink for digital and screen printing. One of the major application they are targeting is the printing of efficient and transparent electrodes on flexible substrates for OLED displays. In fact Genes'Ink says that this ink will work on most substrates and is ready to use. It is compatible with most print heads.
Genes'Ink technology is based on research done at the universities of Marseilles and Grenoble. They claim that their technology offers superior conductivity at a competitive price.
In addition to this new ink, Genes'Ink already developed ZnO inks for printing OLED ETL layers. They told me that they already have customers that use their ZnO ink to produce ETL. The company explains that ZnO is suitable as an ETL because its LUMO level (about 4.4 eV) can improve the work function of the ITO.
