Engineers create Transparent Electrodes for Display Screens

SpecialChem / Mar 27, 2008

South Korean engineers say that they had developed a new transparent electrode that could reduce the production costs of display screens used in computers and mobile phones. The new technology is expected to cut production costs by 50 per cent, and has the potential to greatly expand the use of displays and touch screen panels because it can be bent, the team led by Lee Geon-woong at the Korea Electrotechnology Research Institute (KERI) said. The scientist at the state-run laboratory said the new electrodes are created by using a so-called one-component solution that combines such materials such as carbon nanotubes, binders, stabilization compounds and chemicals that help spread the thickness of the film evenly. He said the liquid one-component solution effectively allows manufacturers to move away from the conventional indium tin oxide (ITO) method that requires high pressure and heat to create transparent electrodes. "The liquid can be applied by a roll-to-roll process, in the form of paste and by means of patterning," the expert said. "
