LG's new 4K TV is thinner than an iPhone

LAS VEGAS — LG's line of high-end televisions has a new king.

The LG W7, just announced at CES, is a 77-inch 4K TV that's thinner than an iPhone. The OLED set will also be available in a 65-inch model, and it's light: the 77-inch version weighs 27 pounds while the 65-inch weighs just 17 pounds. 

The 65-inch set will be available beginning in March and the 77-inch version will be available "in the second half of the year," according to LG. The company hasn't yet announced pricing.
