Inexpensive OLED

Using a new double solvent approach, researchers from the RIKEN Center for Intellectual Property Strategies are able to create a better and less expensive OLED screen. Rather than using spin coated films as before, the dual-solvent concept makes electrospray-deposited films smoother than before. “Using this technology these devices could be manufactured as inexpensively as printing newspapers”, says Yutaka Yamagata.

Yamagata also notes that: “The advantage of using electrospray deposition is that we can fabricate both smooth films and nanostructured film using the same technology.” In the future he believes that this advantage “will also be useful in controlling the structure of organic semiconductor junctions for organic solar cells.”
