It's for detecting when your hands move towards the display, and turning on LEDs in response (for instance, many in-seat monitors have a USB socket with a LED ring around it) - I worked on those units many years ago.

Pretty cool, I guess I never picked up on the behavior because I am mostly on my laptop.
