LG releases 'world's largest' ultra-definition TV

South Korea's LG Electronics on Wednesday began sales of what it claims is the world's largest ultra-definition television, with a view to expanding its share of the premium TV market.

The company released an ultra-definition TV with an 84-inch (213-cm) screen to the local market, with a price tag of 25 million won ($22,067).

LG, the world's number two TV manufacturer, said the new model features not only a large screen but also resolution higher than existing high-definition models, which makes viewers feel "the sense of reality and presence".
