Light-Emitting Paper Could Replace OLEDs

Light-Emitting Paper Could Replace OLEDs
May-02-15
Researchers have created a light-emitting display made out of paper—opening the door a new form of display lighting that is cheaper than LEDs or OLEDs.

Created by a team from the Umeå University in Sweden, the paper is made up of a series of layers sprayed onto a sheet of paper: an adhesive, four conductive layers able to transform energy into light, and a “capping” layer to keep the layers in place. When an 11 volt current was applied to the paper, it glowed as brightly as a standard computer display.

The team believes the paper could function as an affordable—and safer— alternative to LEDs and OLEDs, and could also be used to replace some of the displays and pricing tags in stores.
