LG Display is known to experiment with different concepts for its OLED panels. The latest one toys around with the idea of using the display to vibrate sound instead of relying on separate speakers. If the technology seems familiar, Sony has similar technology it calls Acoustic Surface. That tech has been around since 2017. But what separates LG's experiment with its 97-inch OLED EX panel is it claims to offer a 5.1 channel sound system embedded into the widescreen.
Ars Technica pointed out that it's unclear how this will work, given that the sound comes from a central point. But it's not to say it couldn't produce decent sound. LG Display has shared information on whether the technology will arrive in upcoming OLED televisions, but we'll keep an eye out for it.
