Low-power flexible displays could soon be printed in sizes big enough to cover walls or ceilings. Researchers at the University of California, Berkeley have advanced a process to attach carbon nanotube thin-film transistors on plastic surfaces using low cost printing techniques. The team, led by Ali Javey, professor of electrical engineering and computer science at the university, recently published their findings in Nano Letters.
The transistors are applied like
ink to the plastic substrates using
a gravure printing technique.
Printing nanotubes
isn’t new but Javey claims the
consistent performance his team has demonstrated has
never been achieved before.
Javey and
his team are currently working to
refine the printing process in a
move that will pave the way for printed displays.
