The concepts from Samsung just keep on rolling, and this Ultra Slim 52" LCD is part of the fascinating bunch. So what's so great about a 52" LCD TV? Oh, only the almost non-existent thickness of 40 mm! Not only does the Ultra Slim stay true to its anorexic name, it also has a tapered metallic backing, which means from behind it looks even thinner. Although, that isn't the way we like most things to look like from behind, it works well on LCD TVs. Check out the gallery for the proof. [Samsung. Photos by Curtis Walker]
