Nanotubes hold key to printing large, low-cost displays

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.
