LG Signature 4K OLED W series
The TV is connected to its speaker unit using a proprietary connection. To allow the TV to be so thin, the speakers also act as the input hub for the panel. The speakers - although just a sound-bar - are of the Dolby Atoms standard, and is a fixed part of the TV setup.
The TV will come in 65” and 77” models and will be extremely costly. And they will ship in the next two to three months.
