What is a Virtual Cockpit in an Audi and how does it work?

I've heard about the Virtual Cockpit feature in Audis, but I'm not sure what it does or how it works. Can someone explain it to me in simple terms?

The Virtual Cockpit is a digital instrument cluster located behind the steering wheel in Audi vehicles. It displays important information like speed, RPM, and navigation directions in high resolution, customizable screens. It works by using OLED technology to project images onto the display, giving a sleek and modern look to the dashboard.
