The show-stoppers for both Sony and Panasonic at this year’s CES are 56-inch TVs which combine two of the hottest technologies: OLED and 4K (Ultra HD) resolution. The two companies began collaborating in mid-2012 on the development of the OLED TV technology and are showing their first prototypes at CES 2012. The 56-inch screen sizes happen to one-up the size of the OLED TVs shown by rivals LG and Samsung by 1 inch. Both prototype TVs are produced using a printing-based technology which is said to be easier to mass-produce large 4K screens. Both offer a native resolution of 3840×2160 pixels. The Panasonic TV is a mere 8.9 mm deep and weight just 12.9 kg. Sony did not unveil the specifications of its set. A potential released date or pricing have not yet been revealed.
Also during the Panasonic press conference, the company showed a 20 inch tablet with a 4K screen. The tablet will run on the Windows 8 operating system and come with a stylus. Release date and pricing were not announced.
