Panasonic vies for bragging rights with its OLED TV

The half-inch thick, 56-inch television based on organic light-emitting diode technology is a mere inch bigger than ones unveiled by Samsung Electronics <005930.KS> and LG Electronics <066570.KS> a year ago in Las Vegas.

Sony Corp <6758.T>, which is cooperating with Panasonic in OLED technology - which allows for thinner screens that consume less power in theory - on Monday unwrapped its own 56-inch ultra high-definition model.
