LG's G8 ThinQ is a high end smartphone that features a 6.1" 1440x3120 Crystal Sound OLED, a Qualcomm Snapdragon 855 chipset, 6 GB of RAM, 128 GB of storage, a microSD slot and a triple camera setup.
LG also offers a variant called the G8s ThinQ which sports a slightly larger display (but with lower density) - a 6.2" 1080x2240 pOLED. Otherwise the specifications are quite similar.
The idea is that a CSO display vibrates and turns into a diaphragm - to produce high quality sound. LG says that such a speaker improves the clarity compared to regular smartphone speakers. The G8 ThinQ will also use other audio technology, including DST-X 3D Surround Sound emulation, Hi-Fi Quad DAC, Master Quality Authenticated (MQA) and more.
