China TV maker Skyworth demonstrated several new OLED technologies at IFA 2017. First up is a 77" 4K OLED TV, which you can see on the video below.

Skyworth also demonstrated a Crsytal-Sound OLED technology - which seems to be similar to LG's technology (that also has the same name, which probably means this is indeed based on LGD's tech).

Finally, Skyworth also demonstrated its wallpaper-thin OLEDs, Metz (owned by Skyworth) latest OLED TVs and also mobile-sized flexible OLEDs produced by the company's subsidiary Guangzhou New Vision.
