CES 2013 Live: LG rolls out big-screen OLED, Ultra HD TVs LG's 55-inch OLED HD TV will go on sale in the U.S in March for $12,000, the company announced Monday at the 2013 International Consumer Electronics Show. The LG set is the first big-screen OLED TV and was on display at CES on Monday morning. Even from across a ballroom floor, the set provided crystal clear images while running a demo video. Besides OLED, LG also announced it will expand its line of Ultra HD TV sets with two more sizes: 65-inch and 55-inch sets. They join an 84-inch, $20,000 model that launched in 2012. LG didn't announce pricing or availability of the new Ultra HD models, which display images with four times more detail than the standard high-definition TVs. Salvador Rodriguez Monday is Press Day at the International Consumer Electronics Show, when many of the biggest tech companies host flashy press conferences for thousands of reporters and bloggers. The hoopla kicks off Monday morning with a press conference from LG, followed by events from Sharp, Panasonic, Samsung and other device makers. Expect bigger ultra-high-definition televisions, new organic-LED sets, improved smart TV platforms and surprise celebrity appearances. Later on in the day, a select group of smaller tech companies will showcase their latest gadgets, accessories and apps at the Digital Experience media event at the MGM Grand. Highlights from Sunday's sneak peek day included the "smart electronic" Hapifork, which buzzes in your hands when it determines you're eating too quickly. This apparently fosters both mindful and mindless eating. "Your mind doesn't have to do the work," says inventor Jacquest Lepine. Also, 3M and Lenovo demonstrated their table-top PCs, which allow multiple users. Lenovo's IdeaCentre Horizon Table PC is easy to picture in your living room. 3M went big with an 84-inch multi-touch system aimed at the business market. Meanwhile, Belkin unveiled the Thunderstorm, billed as the first-ever handheld home theater case for the iPad. Stay tuned for more.
