We've been waiting for large-sized OLED (http://techcrunch.com/tag/oled) TVs at least since Sony rolled out the cool (but too small) XEL-1 (http://techcrunch.com/tag/xel-1/) in 2007. Various bigger (http://techcrunch.com/2011/10/04/ceatec-2011-mitsubishi-showcases-semispherical-display-2-7m-diameter/) OLEDs (http://techcrunch.com/2011/04/12/sonys-outs-two-new-oled-monitors/) and "breakthroughs" (http://techcrunch.com/2011/11/21/sumitomo-chemical-reports-breakthrough-in-large-sized-oled-tv-mass-production/) have made the news in the years after that, and now LG says it's ready to showcase the world's biggest OLED TV at CES 2012 (http://www.cesweb.org/) (which kicks off on January 10).
Sized at 55 inches, the panel has a contrast ratio of 100,000:1 and has been developed by using the Oxide TFT (http://en.wikipedia.org/wiki/Oxide_thin_film_transistor) technology, according to LG. The company has been working on bigger OLED devices for quite a while now, for example a super-thin 31-inch model (which was shown last year (http://techcrunch.com/2010/09/02/exciting-video-lgs-oled-tv-is-the-thinnest-in-the-world/)).
So far, so good, but unfortunately LG says they see the device as a step forward in popularizing the concept of large-sized OLED TVs. In other words, the TV is just a prototype at this point with neither a price tag nor a release date, and we might have to wait years before being able to actually buy one.
