Reverse offset printing and specialized inks for organic TFTs

Abstract

We have developed functional inks for reverse offset printing to make high resolution organic thin film transistors (OTFTs). These inks are silver nanoparticle ink, organic dielectric ink, black pigment dispersed ink and organic semiconductor ink. We have also fabricated high resolution OTFT-backplane using these inks and successfully derived polymer network liquid crystal display (PNLCD).
