LG’s G8 phone uses its OLED screen for making phone call audio

Tonight LG has revealed more about its audio setup, which includes a “Crystal Sound OLED.” Similar to LG-developed OLED technology we’ve seen come to market in Sony’s TVs, it vibrates the screen to produce sound, with an effect that the company claims increases volume, with musical notes more discernible and voices clearer.

So the next generation phone screen will be even closer to full screen, maybe we will see more similar design will appear on more phone brands in 2019.
