The panel features LG Display's latest OLED.EX technology in combination with 'Cinematic Sound OLED' that uses the actual OLED panel as a speaker system.

LG Display produces the OLED panels inside LG Electronics, Sony, Panasonic, Philips, Vizio and other brands' OLED TVs so there is a good chance that this panel will make it into a TV from one of the popular brands in the near future.

LG Electronics will launch the first 97-inch 4K OLED TV later this year but it will not be equipped with the in-panel speaker system. At this time, only Sony OLED TVs use this unique technology and Sony refers to it as 'Acoustic Surface Audio'.

- "The newly-unveiled 97-inch OLED.EX display boasts the company’s special ‘Film CSO (Cinematic Sound OLED)’ technology, which allows the display to vibrate and generate the sound directly from the display without separate speakers. A 5.1 channel sound system is embedded into the widescreen, creating a performance that offers a cinematic level of immersion," LG Display explained.

Behind the panel there are actuators that use different parts of the OLED panel as a sort of speaker membranes for the 5 channels, aided by a separate bass speaker. It is not clear from LG Display's description how the panel's speaker system can virtualize rear channels.
