The Korean Advanced Institute of Science (KAIST) says they have developed a new flexible display metal wiring technology. The researchers manufactured the metal wiring by inducing photochemical reaction using laser after self-generated 2-3nm silver nanoparticle photocatalytic from metal-atom melted organic matter. They team also developed a laser-guided pattern adhesive transfer - which is used to pattern solid-state materials from a polymer film to the target film (which is vulnerable to heat).
KAIST reports that the technology enabled ultra-fine silver metal wiring (less than 10?) on various material polymer films and the wiring features high conductivity and high reliability. In fact KAIST claims that the new method will enable cheaper manufacturing (about 1% compared to silver nanoparticle ink!) and the manufacturing speed was improved up to 100 times.
