A couple of weeks ago we reported about new organic-TFT developed by University of Florida researchers, and now we've got some more info. The new transistor design is carbon nanotube based and it can efficiently drive the high-currents OLEDs need, at lower voltages than other designs.

The researchers not only designed a new transistor, but they combined it with emitting materials into a single design, called an OLET (we first reported about OLETs back in May 2010). The new design is called a CN-VOLET (Carbon Nanotube Vertical OLET). They say that this new design is more than eight-times more efficient than other competing devices. It also exhibits longer lifetime and should be easy to manufacture.
