If you thought Sharp’s 4K TV we’ve shown you last week is impressive, think again. Toshiba today unveiled a 55-inch LCD that boasts the same resolution (3,840×2,160 pixels, 4x full HD) but can also display pictures in 3D – no glasses required. The TV will be shown starting tomorrow during the CEATEC Japan 2011 exhibition near Tokyo.

Needless to say, the REGZA 55X3 [JP] is the first TV of its kind. Unfortunately, the resolution stands at “just” 1,280×720 in 3D mode.

The TV features 5,000:1 contrast ratio, LED backlight, a new processor called “REGZA Engine CEVO Duo”, a face-tracking function to enable high-quality 3D pictures for viewers, REGZA LINK, five digital tuners, 10W×2ch+10W speakers, four HDMI ports, and two USB ports.

Toshiba plans to start selling this beast in Japan in December (price: US$11,730).
