Aneeve fabricate a fully ink-jet printed CNT circuit that drives OLED displays

Aneeve Nanotechnologies, a startup company at UCLA's on-campus technology incubator, managed to fabricate a new fully ink-jet printed carbon nanotube (CNT) circuit that is used to drive OLED displays. The company says that this is the first practical demonstration of carbon nanotube–based printed circuits for display backplane applications, and it shows significant performance advantages over traditional organic-based printed electronics.

Aneeve says that this shows that CNT is a viable technology to compete with a-Si and metal-oxide semiconductor for low-cost and scalable backplanes.

This new process uses an ink-jet printing method that can be scaled and be used in a roll-to-roll printing process. In order to achieve a viable solution, Aneeve had to develop a new cleaning process and new methods for negotiating nano-based ink solutions. When used in AMOLED applications, these transistors will be fully integrated with the OLED arrays, and the OLED encapsulation will also protect the CNT transistors.
