LG G8 ThinQ smartphone is featuring Crystal Sound OLED (CSO), a technology that utilizes the phone’s OLED display as an audio amplifier.

Developed in-house by LG, CSO repurposes the OLED display as a diaphragm, vibrating the entire surface to produce sound with impressive volume. And because LG’s technology takes advantage of the entire display, CSO also improves clarity, making voices easier to discern and subtle musical notes more noticeable, according to LG.

In speakerphone mode, audio is delivered with bass through the bottom speaker. Full-bodied stereo performance is possible with a 2-channel audio setup utilizing this bottom speaker and the top part of the display. As well as improving the sound, CSO also gives the LG G8 ThinQ a minimalist look.

What’s more, LG’s newest G series phone features:

• DTS:X 3D Surround Sound that emulates a 7.1-channel system with or without earphones
• Hi-Fi Quad DAC that reproduces sound with fidelity and the added ability to up-sample most audio files for increased clarity and depth
• Master Quality Authenticated (MQA) that supports high-quality audio streaming even without an unlimited data plan
• Boombox Speaker that takes advantage of the internal space of the phone as a resonance chamber to amazing bass and more volume

The LG G8 ThinQ smartphone will be on display at the MWC in Barcelona.
