China TV maker Changhong is reportedly showing a wide range of OLED TVs at CES 2018. One of the TVs employs a similar design to Sony's 2017 A1E with the Acoustic Surface back stand. Interestingly Sony's discarded the design idea in its latest OLED TV, the AF8.

We do not have information about Changhong's other OLED TVs at CES, but it is likely they also had their latest 65" 4K AI-powered Q5A on display.
