What is the Audi A7 Matrix LED system and how does it work?

I've heard about the Matrix LED system in the Audi A7 but I'm not sure how it works. Can anyone explain it to me?

The Audi A7 Matrix LED system is an advanced lighting system that uses multiple LED segments to control the light distribution and reduce glare for other road users. It works by using a camera and sensors on the front of the car to detect oncoming vehicles, then automatically adjusts the light pattern by turning on or off specific LED segments to prevent glare while still illuminating the road.
