LG announced it will reveal a 72" 3DTV at CES 2011:
The company claims it is the world's largest TV with these technical specs. It's the LZ9700, and will probably also be one of LG's most expensive TVs ever.
The TV manufacturer didn't quite detail everything we'd like to know. It didn't say if the TV is going to use active 3D or passive 3D technology
(we'd guess active), or what the price or release date will be.
What it did say, though, was that it will support a whole bunch of TV apps, and it has THX certification. In other words, this is one monster of a TV.
