Researchers from the University of Southern California has created a large functional array of transistors made using simple solution-processing methods from carbon nanotubes. These have been used to drive a simple 4" OLED display, and the group is now working towards a 'truly integrate' OLED display that is both flexible and transparent.

Carbon Nanotubes is a promising material for making control cibruit for displays - they are efficient, and can be used to make flexible and transparent displays. Now the USC researchers have found an 'easy' way to make large arrays of transistors with good performance.
