Electronics giant LG is preparing to introduce the world's largest OLED TV as well as the world's largest 3D LED TV during the upcoming annual show. The LG OLED TV will feature a display measuring at 55 inches, which will have a thickness of merely five millimeters. This next-generation TV is expected to be available in 2013.

The South Korean electronics giant’s second next-generation TV will be the 3D LED TV which will come equipped with a 72-inch screen.

It may be noted here that no manufacturer has ever introduced OLED TV and 3D LED TV with such large screens.

Samsung is reportedly also preparing to unveil a nearly market-ready OLED TV at the CES. The LG's Korean rival will make its CES announcements on January 9.

Both LG and Samsung have already shown prototype OLED TVs at the previous CES shows, but neither of them had ever announced any marketing plans.

Other tech giants like Microsoft and Sony will also reveal their next-generation products at the show, which starts January 10.
