At CES 2017, in Las Vegas, LG Display and Sony came to present a new technology ‘Sound OLED’ by which the audio system is integrated into the display panel. The sound is projected directly into the front, which increases the immersive effect. Another advantage is that the absence of an external loudspeaker allows to further refine the design of these televisions. At LG Display, this technology which is named Crystal Sound OLED is present in a prototype 65-inch Od Ultra HD screen that can be seen in this video shot by the Engadget site. An acoustic transducer transforms the surface of the screen into a loudspeaker membrane that vibrates and diffuses the sound.
For the demonstration, plastic balls were placed on the screen, installed flat on a table, so that one can see the physical effect produced by the audio vibration. According to the testimonies of the journalists present at the CES, this device would not affect the stability of the image, even when the volume is pushed to the maximum. On the other hand, it is not known whether the device can reproduce a stereo or surround effect.
If LG Display is still in the prototype stage, Sony is very close to releasing this technology which it calls Acoustic Surface. The Japanese firm does not provide technical details, but one can imagine that the process is quite similar to that of its competitor. It equips the new Bravia OLED 4k HDR 77-, 65- and 55-inch XBR-A1E TVs, the pricing and availability of which have yet to be announced.
