LG is demonstrating a new technology which they call Crystal Sound OLED - which is an OLED panel that contains an embedded sound system. LG says that this technology is only possible with an OLED panel as it does not require backlights.
LG Display demonstrated a 65" Crystal Sound OLED - and the company says that it provides a better immersive viewing experience as the sound comes directly from the characters on the screen and not from an off-center sound speaker. LGD says it will unveil 55" and 65" 4K Crystal Sound OLED TVs in the future.

You clearly don't understand how stereo works....
Actually there is a stereo image as the screen construction allows for enough isolation between the left and right channel speakers so that a stereo image is created.
"sound comes directly from the characters on the screen and not from an off-center sound speaker"
This sounds like marketing blabla, since the space simulated on screen doesn't match the real space. And there is no way for them to isolate the sounds of e.g. an actor on the left side of the screen.
