Hybrid printing of high resolution metal mesh as transparent conductor for touch panel and OLED
Cui Z., Gao Y.
© 2015 SID. A hybrid printing technique has been developed to manufacture high resolution metal mesh as flexible transparent conductors. The metal mesh structures are made by embedding silver nanoparticles inks into trenches which are patterned by high resolution nanoimprinting technology. Compared to other nanosilver type or metal mesh type of transparent conductors, the new technology can make much finer metal mesh (<3μm) with much higher conductivity (≤1Ω/□) while still maintaining high transparency (>88%). The transparent conductor sheets can be roll-to-roll printed, which offers significant cost advantage over ITO electrodes. The new technology has been successfully implemented in high volume manufacturing of touch panel sensors for displays, as well as adapted to making flexible OLED.
