A 97-inch OLED EX TV panel with the company's Cinematic Sound OLED (CSO) was unveiled by LG Display on Wednesday.
What Is CSO Technology
By vibrating the display using a thin film exciter attached to the panel's back, CSO eliminates the need for extra speakers by generating sounds directly from the OLED, according to the news story by The Verge.
The 5.1 channel system, according to LG Display, will provide a "cinematic level of immersion," with all sound emanating from the TV rather than surround sound speakers positioned behind the viewer.
In other words, LG claims that the 97-inch OLED EX TV panel can produce sounds without using actual speakers.
In case you're unsure whether such technology is possible, Sony has been utilizing a similar technology dubbed Acoustic Surface in OLED TVs since 2017. Also lacking speakers, this TV makes sound by vibrating actuators behind the display.
Sony does not, however, compare Acoustic Surface with 5.1 surround sound. As pointed out by Ars Technica, Sony instead encourages users to "connect their own gear to the set and to use the TV as the center channel for a surround sound setup."
What Is OLED EX and How Does It Works
The 97-inch LG Display panel produces a brighter and more accurate image using the same OLED EX technology as LG's most recent flagship OLED TVs.
But what exactly is an OLED EX technology?
First of all, OLED stands for organic light emitting diode, a technology being used for displays for some years now. Meanwhile, the "EX" part of the OLED EX combines "Evolution" and "eXperience," as noted by Ars Technica.
Due to the use of deuterium and the company's "EX Technology algorithm," LG Display's OLED EX technology, which it first revealed in December, reportedly offers screens that are up to 30% brighter than those found in ordinary OLED displays.
The Verge pointed out that according to LG, the "EX Technology algorithm" predicts the usage of each individual light emitting diode in your TV based on your unique viewing habits, allowing it to precisely control the display's energy input to more correctly represent the details and colors of the video content being played.

OLEX EX, according to LG, will have smaller bezels. According to calculations using a 65-inch OLED panel, the company claims it will be able to reduce bezel thickness from 6mm to 4mm.
In the second quarter of 2022, LG claims it will begin integrating OLED EX technology into all of its OLED panels. It's unclear, though, how much longer it might take for this technology to reach consumers after then, as noted by The Verge.
What Is the Difference Between OLED and OLED EX
If you're wondering what the difference is between OLED and OLED EX, Ars Technica explained that the latter uses deuterium compounds rather than simple hydrogen, which is the distinction between conventional OLED and OLED EX.
Deuterium is extracted from water by the company and turned into compounds that are used in diodes. The diodes should be brighter and more effective after they have stabilized and been combined with LG's machine learning algorithms.
