LG Display has shown off some interesting ideas as it looks to change the way OLED panels work, from positing bizarre form factors to addressing dimmer brightness levels compared to LED alternatives. Now, the panel maker is exploring a new approach to OLED TV audio.

Today, LG Display announced its creation of a 97-inch OLED EX TV panel that debuts the company's Film Cinematic Sound OLED (CSO), "which allows the display to vibrate and generate the sound directly from the display without separate speakers."
