The Korea Institute of Machinery & Materials (KIMM) successfully developed a new technology that can print electronic circuits for flexible displays at the 1µm level.
Lim Young-taek, head of the KIMM, showcased the world's first tech for 1µm electronic printing using roll-printing technology at the World Conference of Science Journalists 2015 at the COEX Convention Center in Seoul on June 10. He predicted that this technology would replace the production process of large displays at the 2 to 3 µm level.
Lim said, “The global printing electronics market will reach US$33.1 billion in 2020,” adding, “I think that we laid the foundations for our advancement with the development of the technology.”
A 1µm line is impossible to see with the naked eye, so it can be used in touch sensors for transparent electrodes. The new technology is also usable in printing smart sensors used in highly-integrated circuit devices and the Internet of Things.
