LG Display debuted its new 97-inch OLED.EX TV panel 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 screen showcases LG’s new film CSO (opens in new tab) (Cinematic Sound OLED) which means the screen itself will vibrate to generate audio without the need for dedicated 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 more channels left and right, plus a subwoofer for bass.
LG Display makes the OLED TV screens used effectively in all the best OLED TVs, including those made by LG Electronics – but LG Display also sells screens to Sony, Philips and others.
Not much is known about the Film CSO or how the sound system will be arranged on the OLED.EX panel. However, it does remind us of Sony’s Acoustic Surface Audio system, which can be found on the Sony A80K. 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 at the rear 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
LG Display debuted CSO technology on its 97-inch OLED screen, which is the “largest OLED TV panel ever made”. Earlier this year, LG released the 97-inch G2 OLED with the screen, so its existence came as no surprise, but this is the first time the screen has been shown in Korea outside of its use on that TV, and it certainly is the first time we saw the new sound system included in it.
OLED EX technology first debuted in December 2021 with LG claiming it can improve OLED brightness by up to 30%. Using different materials (specifically, deuterium) allows for extra energy efficiency, which means you can get more brightness as well as more accurate colors.
LG Display also points out that its OLED.EX panels use “algorithm-based custom EX technology”. This technology is designed to reduce image degradation on the TV. “Custom algorithms thoroughly study people’s usage habits and viewing patterns from day one, predict the degradation of 33 million organic light-emitting diodes on each screen, and maintain optimal brightness and performance in their initial state,” says the LG Display. Basically, the panel looks at what you watch regularly, to compensate for the deterioration of organic pixels over time.
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.
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.
