Korean-based DAWONSIS suggests a new FMM-based method for large-area OLED deposition

Korea equipment maker DAWONSIS developed a new OLED deposition process that is based on FMM but according to the company can be scalable to large-area deposition. This could theoretically enable efficient evaporation-based OLED TV production.

The so-called Joule Heating Deposition process use a large area material source (as opposed to point-sources or line-sources currently used) using a conductive film that is efficiency heated using voltage induction. According to DAWONSIS this process is scalable and also efficient in terms of material usage (which is about 70%-80%).
