LG debuted its new 97-inch OLED.EX TV during K-Display 2022 (opens in new tab) event in Seoul, South Korea, and is taking an unusual approach to audio on OLED screens.
O OLED.EX TV showcases new LG Film CSO (opens in new tab) (Cinematic Sound OLED) which allows the screen to vibrate and generate audio without the need for external speakers. Instead, a 5.1-channel sound system is built into the screen, which the company claims can create “a cinematic level of immersion”. A typical 5.1 system consists of a center speaker with four speakers around it and a subwoofer for bass.
Not much is known about Film CSO or how the sound system will be arranged on the OLED.EX TV. However, it does 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 to Sony to guess how this might work.
Sony TVs with Surface Audio Plus Acoustic It has four front speakers, two actuators and tweeters on the back for immersion. It is the actuators themselves that gently vibrate the screen to emit sound and ensure that the audio is synchronized with the visual. Audio Plus can even be enhanced with an amplifier so that the display acts as the main speaker.
We contacted LG and asked for more information about Film CSO. Specifically, we want to know how the sound system doesn’t interfere with the screen, assuming there are no actuators. This story will be updated if we get a response.
better and brighter
In addition to the audio system, the OLED.EX must have impressive visual fidelity.
LG claims that its 97-inch screen is the “largest OLED TV panel ever made”, which is not true. Earlier this year, it launched the 97-inch G2 OLED, so the company has already reached that milestone. Perhaps it is more accurate to say that LG debuted the biggest OLED TV with OLED.EX technology. There are other TVs with this feature, albeit smaller, 48-inch and 77-inch, being developed by Philips.
OLED EX technology first debuted in December 2021 with LG claiming it can improve OLED brightness by 30%. This is due to a substance called deuterium (aka heavy hydrogen), which is an isotope of hydrogen that packs an extra neutron. Without delving into the scientific details, this unique atomic structure allows for brighter displays.
LG also claims that its TV can produce true-to-life color and finer detail thanks to “algorithm-based custom EX technology.” We reached out to LG again to find out what that term means. We’ll update this story if we get a response.
The price is also unknown, but for reference, we can look at the 97 inch LG G2 screen. It costs about $27,000.
Also at the K-DIsplay 2022 event, LG showcased more of its transparent OLED displays, which were first seen in December 2021. (opens in new tab).
We’ve seen how they would look in a store environment, but we got a preview of how transparent screens can work in an office. LG has unveiled a new model, the Transparent OLED Solution for Conference Room; also known by its more succinct name, the E-Crystal.
O e-crystal (opens in new tab) It is a glass wall equipped with OLED panels that can be used as a monitor to display graphics. It is designed to free up space in conference rooms that can normally be occupied by multiple monitors. Release dates and pricing for all of LG’s transparent OLED displays are unknown. We will be looking forward to more news.
For those interested in display technology that is not transparent but flexible, Samsung just held its Unpacked 2022 event, where the tech giant unveiled the new Galaxy Fold 3 and Watch 5 Pro. We recommend checking out our recap for a quick summary.
