The LG G8 Comes with a Vibrating OLED Screen for a Speaker
​February 18, 2019
 
LG announced that the new G8 ThinQ smartphone would come with the OLED screen that acts as a speaker. The speaker uses CSO technology that emits sound from the whole screen, so customers can hear the sound by placing ear anywhere during a call, and not specifically on a receiver. When in speakerphone mode, the sound is heard from the microphone at the bottom of the device and 2-channel stereo sound is available. The LG G8 uses the same “Crystal Sound OLED” branding as some OLED TVs, where shows the entire display vibrates to function as a speaker. It will be the first flagship G-series phone that is not using an LCD. The G8will come with a front-facing 3D camera and will have a time-of-flight sensor, and there might be an optional second screen accessory. The G8 still has a bottom-facing speaker for louder use cases like speakerphone calls, and LG says this can be paired with the top part of the screen for 2-channel stereo sound. Elsewhere, the signature quad DAC from LG’s recent flagship phones returns — which means there’ll be a headphone jack — as does the “Boombox Speaker” functionality that produces surprisingly bassy sound when the phone is placed on a table.
