LG to Showcase 84-Inch 3D HDTV at 2012 CES

The device will feature four times the pixel density of 1080p HDTVs and can display eight million pixels at a resolution of 3840-by-2160.

LG has some big plans for its television lineup at the 2012 Consumer Electronics Show in Las Vegas. The company has announced that it plans to debut an 84-inch high-definition 3D television set that features four times the pixel density of 1080p HDTVs. Also known as 4K resolution, LG's 84-inch HDTV can display eight million pixels at a resolution of 3840-by-2160.

LG claims its 4K set is the world's largest 3D Ultra Definition (UD) TV. The electronics maker did not announce pricing or availability or whether the 4K HDTV is still in its prototype phase. LG originally debuted an 84-inch 3D UD TV during CES 2011, according to CNET UK.

LG has added a few new goodies to the 2012 version of its 84-inch 4K set including access to LG's catalog of more than 1,200 Smart TV apps and a new remote control that features voice, gesture, point and scroll wheel inputs.

Next-generation HD on tap

Many electronics makers spent 2011 showing off next-generation HDTV prototypes. In July, Samsung demonstrated a 70-inch 3D UD TV with 4000-by-2000 resolution (dubbed 4K-by-2K). Sharp, meanwhile, teamed up with NHK (a Japanese broadcaster) in May to show off an 85-inch prototype Super Hi-Vision display with 7680-by-4320 pixel resolution, 16 times the resolution of 1080p. Plans to begin trial broadcasts of Super Hi-Vision are slated for 2020.

During CES 2011, Toshiba was showing off a prototype 4K glasses-free 3D television set, according to Engadget. Then in September, Toshiba followed up its CES demo by launching a 55-inch 4K HDTV set in Europe with a price tag of more than $10,000.

LG's so-called world's largest 3D UD TV will have some company during CES 2012. The electronics maker had previously announced that it would debut the world's largest OLED HDTV panel (55 inches) in Las Vegas.
