Cadillac announced that the upcoming 2023 Lyriq EV will sport a wide 33-inch "advanced LED" display, and according to reports online this will actually be an OLED display.
This makes sense, as Cadillac is already using OLEDs in its premium cars. The 2021 Escalade has a 38-inch LGD P-OLED display, that comes standard in all Escalade versions.
The Lyriq display is smaller, but will likely to be quite similar. The Escalade display is built from three different display panels - a 7" display, an 14" one and a 16.9" display. The center 14" is the instrument cluster and it is not-touch enabled (the other two do include touch). We do not yet know the actual design of the Lyriq pOLED.
