Flexible colour monitors, e-paper may soon be a reality

E-paper, flexible colour monitors, and “heads-up” displays in car windshields may soon be a reality, for engineers have already made the first “active matrix” display using a new class of transparent transistors and circuits.

The researchers say that they used nanowires, about a thousand times thinner than a human hair to develop the display containing organic light emitting diodes (OLEDS) — devices that rival the brightness of conventional pixels in flat-panel television sets, computer monitors, and displays in consumer electronics.

“This is a step toward demonstrating the practical potential of nanowire transistors in displays and for other applications,” said David Janes, a researcher at Purdue University’s Birck Nanotechnology Center.
