The 2022 Mercedes EQE electric car comes with either a 12.8-inch AMOLED or (optionally) Mercedes' MBUX Hyperscreen. The Hyperscreen is a 56-inch display, actually made from three different OLED units, embedded in a single glass display. There's a central 17.7-inch panel plus two 12.3-inch panels. The 56-inch glass also includes holes for the air-vents which are integrated into the display.
The MBUX Hyperscreen was first used in the higher-end EQS electric car. The 'lower-end' 12.8-inch AMOLED screen, shown below, is used in the 2021 S-class cars. We speculated that LG Display is supplier to Mercedes (the two companies have been working together since around 2016) and LG Display earlier this week officially confirmed that it is indeed Mercedes' OLED supplier.
