The objective is to develop nanostructured OLEDs by implementing a cathode-organic layer interface that has improved electron injection efficiency and is environmentally stable for ease of manufacturing and long product life. This approach represents a fundamental shift in design of OLED cathode materials and structures. The primary benefit is the expected development of patterned OLED cathodes that are less sensitive to the environment thus reducing the need for vacuum processing and packaging. A secondary benefit of the proposed technology is the potential of scale-up patterning of cathode into photonic structures that can effectively out-couple light that is otherwise unavailable with conventional planar geometry.
