LG Electronics will unveil various OLED TVs including the world's largest 77-Inch curved ultra HDTV at the Consumer Electronics Show 2014, which opens in Las Vegas next Tuesday.
OLED panels consume about 30 percent less power than LCD displays and are so flexible that it is possible to make a curved screen.
The electronics giant in a press release said the 77-Inch TV has four times as many pixels as existing high-definition TVs. It is going to release the product commercially in the first half of the year.
Other models include the Gallery OLED TV with a panel mounted on a picture frame, and an environmentally friendly curved OLED TV built with fewer components and recyclable materials.
Meanwhile, Samsung will unveil a new wireless audio/video multiroom system at the CES, a spokesman said. Its M7 and M5 series have wireless speakers that can be connected to TVs, blu-ray home theater systems, or smartphones with a Bluetooth wireless device.
