“From liquid crystal display (LCD) panels and touch panels to electronic paper (e-paper), solar cells and more, indium tin oxide (ITO) is extensively used as the material for transparent electrodes. New transparent electrode materials are reaching the level of practical use now, though, and will replace ITO thanks to characteristics including improved bending, lower cost and higher transmittance. Already these new materials are entering use in touch panels, and e-paper will follow suit shortly. In the near future, the trend may spread to applications such as solar cells and LCD panels, too.”
