Mercedes Benz announced that its upcoming 2021 S-Class cars will include up to five touch displays, and one of these will be a 12.8" OLED display with haptic feedback. The OLED display will come standard in all the cars in the series.
Mercedes is likely to be using LG Display's OLEDs, as the two companies have been working together since around 2016.
In 2018 Mercedes started to offer optional OLED taillights in some of its cars. The supplier of these OLEDs is LG Display.
