We demonstrate an ultra-precise deposition (UPD) technology for fabrication of next-generation displays. UPD allows deposition of highly-concentrated silver inks (up to 85% wt. of solid content) on complex substrates. The printed feature size is from 1 to 10 μm, with the electrical conductivity up to 40% of the bulk value.
