Sony and Panasonic said on 25th December that they will end joint development of organic light emitting diode (OLED) television screens.
The two companies will instead focus their efforts on 4K Ultra HD televisions.
Sony and Panasonic had formed the OLED alliance in June last year with the goal of developing mass-production technology by the end of 2013.
Both companies will display 56-inch OLED televisions at this year’s CES electronics show in January. A spokesman said they would continue independent efforts to develop OLED technology.
