OLED-Display.net have a exclusive Video from VTT which was a two-colour OLED element that is attached to a product package. When the package is unopened, a green tick is displayed. When the package is opened, the fuse is blown and the tick changes into a red cross.

The OLED element developed under the ROLLED project is made from organic materials and is encapsulated in a moisture barrier film. The element is 200–250 micrometers thick, the equivalent to three or four sheets of paper.

The current production cost of an OLED element is tens of cents. Researchers, however, are aiming for some end applications that cost as little as just a few cents.
