Many companies want to introduce a technology which they can print OLED-Displays , Panasonic, Kateeva, Dupont are developing this kind of technology. Panasonic showcased printed OLED-Television panels at CES-2014 , but the major problem are the organic material. But the major companies explained how material technology is rapidly improving. The efficiency and lifetime of red and green emitting materials with the hole carrier materials (HIL, HTL) based on printing ink type dissolved in solvent rech up to the level of evaporated emitters. You have to learn that the evaporation method in high vacuum chamber has major problems because it is difficult to evaporete either in small pixel or in large panel size. The costs are high because with this process the companies has about 70 percent waste of the material. To print OLED materials they are first transformed into the printer, and then they print out the material with only 10 percent waste of material. This process is very simple the companies can minimize material dissipation and can produce cheaper and larger panels. The companies need to develop highly efficient, durable materials that are printable.
