Swedish tech site Nordic Hardware got to see the LG Signature W7 OLED at CES 2017. This OLED TV will be launched in 65" and 77" versions and must be mounted to your wall via a magnet-based mount.
The panel itself has a thickness of just 2.67mm, which increases to a total of 3.8mm if you include the mount. The W7 has a maximum brightness of 1000cd/m² and is described as WallPaper OLED.
One of the problems with these thin TVs is what do you to with the cables? LG tried to solve this problem by shipping the device with a Dolby Atmos speakerbar. This bar is designed to be mounted under the TV, it connects to the panel via a flat cable and features all the display inputs.
