A few weeks ago we reported that Sumitomo Chemical began construction of a PLED material factory (which will be operational in 2012) in a several billion yen investment. These materials are aimed towards large panel (OLED TV) production. Today we have a new report that say that Sumitomo made a breakthrough in its PLED material technology - which will eventually enable production cost to be slashed by up to 50% (compared to SM-OLED based displays).

The annual output of their new Osaka plant will be enough to produce 4-5 million 40" OLED TVs. Sumitomo plans to offer these materials to TV makers in Japan, South Korea, and Taiwan. PLEDs (or Polymer-OLEDs, sometimes called PLED too) are OLED devices made from polymer (large-molecules) materials and are more easily adapted for printing (solution-processable) compared to Small-Molecule OLEDS (SM-OLEDs). Some companies believe that PLEDs are the best way to create large OLED panels using printing methods. You can read more about PLEDs here.
