Researchers Discover A New Way To Improve The Current Injection In OLED Devices
Mar 15, 2018

Researchers from the Max Planck Institute for Polymer Research developed a way to improve the current injection from the positive electrode in the OLED panels. To enhance the hole injection, the researchers covered the positive electrode with an ultrathin layer of an organic semiconductor as a spacer layer between the electrode and the light-emitting organic semiconductor.

The researchers say that they did not actually expect that adding an extra layer and eliminating the physical contact between the electrode and the emitting layer actually improves the electrical contact.
