OSRAM is one of the leaders in OLED lighting (apparently focused on the automotive market), and currently the produce all their OLEDs using an evaporation process. But according to a new job post, the company is starting to research wet-deposition of OLED materials.
OSRAM is looking for a PhD candidate that will work on a pre-development project involving wet-deposition of OLED materials. The challenge is to find the right process and material and process for each layer in the OLED lighting device. OSRAM specifically mentions screen printing, intaglio printing, flexograph and inkjet printing.
As OSRAM themselves say, this is a pre-development project, but it is good to see this important OLED lighting developer starting to look at ways to lower the cost of OLED panels using different deposition processes.
