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.

Panasonic also had a nice OLED lighting "tree" made from Panasonic Idemitsu OLED Lighting (PIOL) ELeaf panels. PIOL is a joint-venture between Panasonic Electric Works (PEW) and Idemitsu Kosan that is already shipping OLED panel samples. PEW announced that they developed the world's most efficient OLED devices (128 lm/W) and Panasonic themselves developed the world's most efficient OLED panel at 114 lm/W (for 1 cm2).

In the video above, published by Panasonic you can see the OLED TV panels and also the OLED lighting tree (on the lower left at 2:10).

Thanks Sri for the OLED lighting photo!
