How to print wall-sized displays
August 22, 2013
Adapting conventional printing technology, UC Berkeley researchers have developed a way to rapidly and inexpensively make uniform arrays of high-performing transistors out of carbon nanotubes on flexible plastic sheets, MIT Technology Review reports.
The process could eventually lead to a tool for manufacturing large-area, low-power sensor arrays and displays.
Thin-film transistors made from carbon nanotubes are attractive for these types of applications because they are robust and mechanically flexible, and they can be much more energy efficient than silicon transistors.
They can also be applied as a solution, or “ink,” and can be processed at relatively low temperatures, making them compatible with plastic substrates.
