At the CES 2018, LG Display presented the prototype of a television that can extend and retract its (65", i. e. 1.65m) screen. The 4K OLED display is rolled into a kind of inconspicuous box. According to LG, this new technology opens up several possibilities: when the TV is not in use, there is no black surface in the room. This makes sense, especially since modern televisions are getting bigger and bigger, which is nice to look at when there is a picture on it, but it is even more annoying when there is no picture.
LG displays rollable 65" OLED TVs
According to the LG, other uses could consist of rolling out only a part of the display visibly, e. g. for the permanent display of time, weather data or a news ticker, or to adapt to the ultra-wide 21:9 cinema film format, so to speak natively. The model presented at CES is just a prototype to demonstrate the technology of a large foldable display - as LG's display division does not manufacture any devices itself, TVs equipped with the roll-up display will have to come from other companies. Unfortunately, there is no price for the 4K C65" OLED TV shown on the CES 2018n as well as for a release date.
