Panasonic shows OLED TV and lighting prototypes at IFA 2013
As promised, Panasonic showed 56" 4K (3840x2160) OLED TV panel at the IFA 2013 exhibition. The company had several prototypes on display, and I believe these are the same panels as the ones Panasonic unveiled at CES 2013 in January 2013.
Panasonic panels are made using an "all-printing" method, and Sumitomo Chemical revealed that these prototypes use the company's PLED materials. Panasonic's panel uses a substrate (probably Oxide-TFT) provided by Sony (which are actually made by AU Optronics) - as part of the two companies collaboration. According to the latest reports, they only plan to start OLED production at around 2015.
