In June 2012, Sony and Panasonic announced that the two companies will jointly develop technologies for OLED TV panel mass production. Now the two Japanese companies have announced that they have canceled the joint development. They will continue to develop OLED technologies independently, but will focus on UHD LCDs.

In January 2013 (during last year`s CES event), the two companies unveiled 56" 4K OLED TV prototypes. The Oxide-TFT substrate was produced by AUO. Panasonic used an ink-jet printing process, Sumitomo`s P-OLED materials and a direct-emission architecture. Sony used their own Super Top Emission OLED technology and evaporable OLED materials.

It may also be that the production technologies chosen by the Japanese companies were simply too complicated and costly to develop at this stage. This seems to be good news for Korea`s LG and Samsung as these two companies continue their strong push into OLED TV production.
