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 Cinematic Sound OLED (CSO), "which allows the display to vibrate and generate the sound directly from the display without separate speakers.".
Sony has used similar technology called Acoustic Surface in OLED TVs since 2017.
Considering audio will be coming from a central point rather than all around you, it's hard to imagine LG Display's gargantuan TV panel can deliver the surround sound experience of a movie theater.
Audiophile site What Hi-Fi?, for example, called it the "best-sounding TV" it had ever tested, with a "good spread of sound" and directness that worked well with dialogue. FlatpanelsHD reported that voices on the A9G sound like they're coming directly out of characters' mouths and that the overall sound is "significantly better than average TV speakers," though the site still recommended external audio for the best experience.
LG Display announced its OLED EX technology in December, saying it provides up to 30 percent brighter screens than standard OLED displays, thanks to the use of deuterium and the company's "EX Technology algorithm.".
LG Display didn't detail any upcoming TV products with its vibrating OLED EX panel.
