SEOUL -- LG Electronics has unveiled the world's first rollable smartphone at the CES, the world's biggest consumer electronics and technology expo, leading the competition for the next display form factor in the handset market, following the success of Samsung Electronics' foldable smartphones.
LG released a five-second teaser scene, featuring a smartphone with the display rolling out to expand as the case slides up at the digital show on Monday. The company said the product will be launched later this year.
