Sony backed away from OLED TVs by showing off its Crystal LED TV prototype at CES last year, but it looks like the company could be competing with LG and Samsung this time around. Sources tell us that Sony will show off a 4K OLED TV at CES 2013, meaning it could be our first chance to see an Ultra High-Definition OLED display. LG said last year that it plans to launch a 4K OLED set in 2013, but we haven't heard anything since.

Sony was the first company to announce a commercial OLED TV back in 2007, but its XEL-1 set was only 11 inches big; unsurprisingly, it failed to make much of a splash in the consumer space. The company did tell us at last year's CES that it was continuing to work on OLED technology — we'll see if this is the year that it returns to the field.
