New Insight into the Electric Field Distribution in OLEDs

We report on an investigation of the electric field distribution inside organic light emitting devices (OLED's) using a combination of experimental study and numerical model simulations. Such an approach provides insight into the mechanisms responsible for the observed qualitative change in the electric field distribution as the applied voltage is increased. We found that the averaged electric field inside the hole transport layer is larger or equal to the average field in the emission layer over the entire current range.
