We demonstrate a novel ultra-precise deposition (UPD) technology for next-generation displays. UPD allows maskless deposition of highly-concentrated silver and copper inks (even 85% wt. of metal content) and the printed feature size is as small as 1 micrometer with the electrical conductivity up to 45% of bulk value.
