So what about that Cinematic Sound bit of the LG bendable monitor mentioned earlier? According to the report, this is a 0.6mm film exciter underneath the display. And this turns the whole OLED panel into a speaker. This sounds quite similar to the tech found in the Sony Bravia A1 TVs from back in 2017.
Technically speaking, it sounds pretty impressive. But on the flip side, it sounds like it will cost a pretty penny once it becomes available in the market. And LG is likely to announce those details a while after CES 2021 itself.
