Printed CNT transistor circuits may lead to cheaper OLED displays


While flexible OLED displays have begun appearing in some cellphones, the technology is still too expensive to be widely used in consumer electronics. In one of the latest attempts to enable low-cost mass-production of OLED displays, researchers have fabricated the first complete thin-film transistor circuits printed with a carbon nanotube solution for use with display electronics. They found that these circuits are not only easy to fabricate, but they also work as excellent current switches when connected to OLEDs. The printed transistor circuits were developed by a team of researchers at the University of California at Los Angeles; Aneeve Nanotechnologies, a startup company at UCLA; and the University of Southern California, Los Angeles. Their work is published in a recent issue of Nano Letters. more
