Inkjet-printed, silver ring coating to replace ITO

The Touch Screen industry has been searching for a replacement to ITO (Indium Tin Oxide) over the last few years due to limitations in flexibility, screen size, as well as patterning cost and complexity. Based on the coffee-stain effect, ClearJet uses inkjet to print ring patterns made of silver nanoparticles. This introduces a novel approach to ITO replacement. ClearJet's solution includes deposition and patterning in one step, via proven industrial inkjet technology. The resulting substrate meets or exceeds industry conductivity and transparency standards, enabling flexible and large touch screen applications, with a unique, low-cost solution. © 2013 Society for Information Display.
