Sumitomo Chemical announced it has developed a new PLED inkjet-printing technology that achieves 423 PPI on glass substrates sized 370x470 mm. We don't have more information about Sumitomo's new production process, but apparently it isn't ready for commercialization yet as the company says they will "continue to improve the performance and process of PLED materials".

Panasonic used Sumitomo's PLED materials in their 56" 4K2K printed OLED TV prototype shown at CES 2013. Panasonic and Sumitomo has been collaborating on OLED TVs since 2009. The companies hope that ink-jet printing will enable them to lower the production costs of OLED panels compared to evaporation based production. Panasonic aims to launch their first OLED TVs in 2015. The company is collaborating with Sony, and may setup a production-JV together (although if this happens, it's not clear which production technology will be used).

Sumitomo Chemical is also developing printed OLED lighting panels. Just a few weeks ago the company unveiled new flexible structured ink-jet printed P-OLED lighting panel prototypes. Sumitomo plans to start volume production of such panels by March 2015 (fiscal year 2014) - using both ink-jet and roll-to-roll processes.
