DuPont OLED Liquid Printing Process Technology Achieves Significant Cost Savings

55" Display OLED Fabrication Cost

30% below incumbent LCD costs and nearly 50% below equivalent evaporated panels

The DuPont liquid printing process technology is scalable to large motherglass size—one of the major drivers of manufacturing cost reduction in the display industry. Scalability may result in lower material consumption. Printers also cost less to purchase, maintain and operate than evaporators, so capital and fixed costs are reduced.

Taking a closer look at material consumption, it is easy to see the distinct advantage of using DuPont technology versus thermal evaporation, which remains a relatively inefficient deposition technique. Specifically, the layers processed with the liquid printing process consume only 1-1.3 grams for coated layers and 0.6-2.0 grams for printed layers, depending on the selected architecture. In sharp contrast, 5-10 grams of OLED material are consumed for each gram of material evaporated onto the area of the substrate when thermal evaporation process is used.
