Stretchable OLED Display Is Here; No Stretchable iPad Yet
By Chris Brandrick
It seems like flexible electronics are a holy grail of sorts. While futurisitic foldable gadgets may still be quite a ways off, but some new developments out of UCLA might bring them just a little closer to reality.
UCLA researchers have been hard at work, developing pliable OLED displays that could be rolled up, just like an ordinary piece of paper, or stretched out.
A paper originally published in July, titled “Intrinsically Stretchable Polymer Light-Emitting Devices Using Carbon Nanotube-Polymer Composite Electrodes”, sheds light on the project: It details that the engineers have successfully managed to create a metal-free organic light emitting diode (OLED) display that can stretch up to 45% its original size.
Researchers created the unique OLED-based display, which is made up of an area of just 2cm by 1cm, by way of layering a carbon nanotube and polymer electrode on to a stretchable plastic. A report on Technology Review explains the development in depth, detailing that this stretchy display was achieved by tightly layering the electrodes around a light-emitting plastic, which shows light when a current passes through it.
When the technology matures, these stretchable electronics could be used for a variety of means, such as consumer electronics, interior design or medical devices.
