Researchers in Canada have created organic light-emitting diodes (OLEDs) on flexible plastic substrates that retain the high efficiency of their non-flexible counterparts. The advance could help OLEDs make the leap into flexible displays.
OLEDs have several advantages over their inorganic counterparts. Unlike normal LEDs, for instance, OLEDs do no not contain toxic heavy metals, such as arsenic, which have been banned in many jurisdictions. Another advantage is that OLEDs are amorphous: they can be made into a variety of different shapes and forms. The most promising are designs on flexible plastic, which can be used to make roll-up computer displays or light-emitting wallpaper.
