Panasonic today unveiled a new 56-inch 4K OLED TV during its CES keynote, just a day after Sony announced its own 4K OLED display — and it's at least as beautiful as Sony's new television. We got a chance to see it on the show floor, and the quality is stunning; it's a sharp display with rich colors and deep blacks, as you might expect for an OLED television at such a high resolution. The company announced the display at its State of the Industry keynote address today, delivered by company president Kazuhiro Tsuga. Much like Sony's 56-inch TV, Panasonic's new 4K set up is still in prototype mode, so it's unclear when we may see it hit the market, though it certainly looked impressive while on stage this morning. The display measures just 0.5 inches in thickness and, interestingly enough, was manufactured using 3D-printing technology. Tsuga didn't reveal any details on price range, but we'll provide more information as it comes in.
