Sony has released new Ultra HD TVs sized 49-, 55-, 65- and 70-inch at CES 2014.

　　Panels for the TVs are expeced to come from LG Display and AU Optronics (AUO). Previously, Sony has been reliant on AUO for Ultra HD TV panels but will now look more to LG for production of panels such as 49-inch units.

　　Sony's 49-inch TV is expected to compete against 49-inch units from Korea vendors, according to market observers.
