LG’s prototype Ultra HD 4K display begs to be touched
4K displays are all the rage here at CES 2013, but the vast majority of the ones that we have seen have been traditional TV sets. In addition to all of those high-resolution TVs, LG is showing off something different. The company is demoing an 84-inch 4K Ultra HD display prototype with five-point multitouch interaction. If you ever wanted to own an iPad the size of your living room wall, this would be it.
