LG continues to tease the features in the upcoming G8 ThinQ smartphone-- with the next feature involving the fact the smartphone produced audio through the display through the addition of Cystal Sound OLED (CSO) technology.
Developed in-house by LG, CSO is a technology already used by the company to produce TVs able to produce surround sound despite lacking actual speakers. To do so, CSO embeds a audio system into the OLED panel. The screen acts as the speaker membrane, while exciters dotted around vibrate in order to produce sound.
