CES 2019: TV set maker LG makes its sets disappear

In this age of smartphone streaming, big television sets are no longer the centerpiece of many living rooms. Now South Korean electronics company LG is doing its part to make TVs disappear altogether.

LG has unveiled a "rollable" TV — a 65-inch screen that can roll down and disappear into its base with the press of a button. LG and other companies are offering previews ahead of today's official opening of the CES gadget show in Las Vegas.

In the meantime, LG, Samsung and others unveiled "8K" sets, with four times the resolution of today's high-definition sets and twice that of 4K sets such as LG's rollable one. 8K represents the next generation of television viewing, but one that most people won't see for themselves for some time.

So far, 8K has only been deployed for the occasional experimental broadcast, such as during the Olympics. Even 4K shows and movies are just starting to catch on.
