There are three ways in which it can be used: Full View, which is relatively self-explanatory; Line View, which just unrolls a small portion of the screen for displaying things like a clock, the weather, and music control; and Zero View, in which the display is completely retracted. The TV can still play audio while in Zero View via the 100w front-firing Dolby Atmos audio system in its base. And it supports Amazon Alexa, so it could theoretically double as a fancy speaker.
LG has not yet revealed any details on pricing or availability for consumers.
