Scientists from the Faculty of Physics and Applied Computer Science at the University of Lodz (UŁ) have created a display in OLED technology (using self-contained organic light sources) with a graphene electrode. 

Thanks to the flexibility and transparency of graphene, it may be a breakthrough in the development of the so-called flexible electronics, enabling the construction of plastic (freely bendable) monitors, screens and displays. This is the first such device in Poland and one of the few in the world.

A unique solution developed by scientists from Łódź will modify the graphene layer of the electrode with rhenium oxide.

Dr. Paweł Krukowski from the University of Lodz explains, that it was necessary because graphene, although elastic and transparent in 98%, has an inadequate level of the so-called output operation, which allows the LED to flash. Only when a rhenium oxide layer is added to the graphene layer, the output work level turned out to be optimal.

Scientists from Łódź are now working on improving their flexible display, examining its operation in detail.
