How does the Matrix LED technology work in the Audi A8?

I've been considering buying an Audi A8, and I keep hearing about its Matrix LED technology. Can someone explain to me how this technology actually works and what its benefits are?

The Matrix LED technology in the Audi A8 uses a matrix of individually controlled LED lights to provide adaptive and precise lighting for the driver. This results in better visibility and improved safety on the road.

Not only does the Matrix LED technology in the Audi A8 provide better lighting, but it also has advanced features such as high-beam assist and dynamic turn signals for an enhanced driving experience.
