LG Display showed off some interesting ideas to change the way OLED panels work, from introducing strange form factors to tackling dimmer brightness levels compared to LED alternatives. Now, the panel maker is exploring a new approach to OLED TV sound. From the report: LG Display today announced a 97-inch OLED EX TV panel that debuts the company’s Cinematic Sound OLED (CSO), “which allows the display to vibrate and generate sound directly from the display without separate speakers.”

“The 5.1-channel sound system is built into the wide screen, creating a performance that delivers a cinematic level of immersion,” LG Display said. Sony has been using a similar technology called Acoustic Surface in OLED TVs since 2017. These sets also don’t use speakers, instead vibrating actuators behind the display. However, Sony does not compare the Acoustic Surface with 5.1 surround sound. Instead, it encourages users to connect their own equipment to the set and use the TV as the center channel for the surround sound setup. Given that the sound will come from a central point and not from all sides, it’s hard to imagine that the giant panel of the LG Display TV can provide the surround sound of a cinema.
