Image credit: Pochiang Chen, et al. ©2011 American Chemical Society (PhysOrg.com) — While flexible OLED displays have begun appearing in some cell phones, 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 (CNT) 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.
