Create a flexible OLED

The flexible displays are being developed at breakneck speed. Researchers at the University of California, Los Angeles, UCLA, have gone a step further and created an organic diode light emission, which is also a flexible OLED, which would roll up screens to swell and shrink, so that opens a world of possibilities to create, for example, a robotic skin.

If the LED lights have changed the world of light and lighting due to its high efficiency, OLED , electroluminescent organic materials manufactured, have revolutionized the world of the screens. Many researchers are working on the many possibilities that this system . A large number of devices already incorporate this technology , but the capacity to create new display systems are virtually endless.
Now, in the UCLA have been turned back over to the nut of the development of new capabilities. So far they had gotten this type of device to bend, creating flexible displays, but they never stretch. Thanks to the new teacher development Qibing Pei and his team of American college itself that can stretch and shrink the screens with OLED technology.

A flexible and elastic sandwich
To achieve this new quality into devices until stiff, the researchers used a liquid polymer that becomes an elastic solid when exposed to certain types of light. Thus, irrigated by the network of carbon nanotubes adhere to it getting to be elastic. Later, joining two layers of carbon nanotube electrode such that emit light when current runs through them, like a sandwich, the flexible sheet is constructed. This device can stretch up to reach 45 percent in size without losing its ability to luminescence.
With this type of innovation is not difficult to think that future robotic skins are built to function as touch screens , or devices that are suited to new features that require more flexibility.
