First seen at the K-Display 2022 event, LG’s OLED.EX TV debuted alongside new transparent displays.
LG debuted its new 97-inch OLED.EX TV during the K-Display 2022 (opens in new tab) event in Seoul, South Korea and it’s taking an unusual approach to audio on OLED displays.
The OLED.EX TV sports LG’s new Film CSO (opens in new tab) (Cinematic Sound OLED) feature that allows the display to vibrate and generate audio without the need for external speakers. Instead, a 5.1 channel sound system is embedded inside the display which the company claims can create “a cinematic level of immersion.” A typical 5.1 system is made up of a center speaker with four others surrounding it and a subwoofer for bass.
Not much is known about Film CSO or how the sound system will be arranged in the OLED.EX TV. It does, however, remind us of Sony’s Acoustic Surface Audio Plus system which can be found on the Sony A80K TV. Ultimately, we don’t know how similar LG’s feature will be as there’s very little information on Film CSO, but we can look at Sony to guess at how it might work.
Sony TVs with Acoustic Surface Audio Plus has four front-facing speakers, two actuators, and tweeters in the back for immersion. It’s the actuators themselves that vibrate the screen delicately to output sound and ensure audio is synched with the visuals.
