In 2014, LG announced that it built an 18-inch OLED panel that rolls up just like a newspaper. Now, it's ready to show off its ultra-thin beauty to the public CES. It's just one of many concepts that LG hopes will show off what it can do with OLED these days. Back when it was first announced, LG said the rollable OLED panel was only 3 mm thick and featured a 1,200 by 810 pixel resolution. It's unclear if anything has changed over the years, but we'll report back once we check it out. More so than curved screens, thin rollable displays could make truly futuristic devices possible -- imagine a digital news reader that actually felt like a newspaper.
