LG has announced that the next LG G8 ThinQ will be equipped with a unique new feature that allows the screen to be used as a speaker. This feature is called Crystal OLED or Crystal Sound CSO and uses the display as a movable membrane to vibrate the entire surface. This allows the screen to act as a second channel and work with the dedicated speaker on the bottom of the phone to create a stereo audio effect.

This new technology for smartphones was introduced last year for the first time in the OLED televisions from LG. Sony has this even longer in its televisions and calls it Acoustic Surface technology.

For TVs, functionality works well due to the size of the display surface. It also helps to locate the sound and gives the impression that the dialogue comes directly from the characters on the screen and not from other places in the room. For smartphones, the effectiveness of the technology with a much smaller interface remains.

The G8 ThinQ features meridian-powered audio and the DTS: X 3D surround effect that emulates 7.1 sound through headphones or speakers. The phone will also include a headphone jack with a Quad DAC system and MQA support. Last year’s Boombox Speakerphone feature will also be included, allowing the phone to vibrate the surface it is held on to produce a louder and richer sound.

The LG G8 ThinQ will be officially announced at the MWC 2019 in Barcelona.
