It’s for factory workers that assemble laptops. Despite the label, it’s perfectly ok to touch it. There’s a flex PCB behind the label that drives the backlight and converts the eDP signal to pixels. It’s normally protected by the laptop bezel so it’s somewhat fragile. If you bend it, you’ll break traces on the PCB or pop components off.

Maybe I'm remembering old tech, but doesn't that also have thousands of volts in it?
You are! My first laptop ~15 years ago had a super thin (1mm?) fluorescent tube below the panel where the flex PCB would be. It used thousands of volts to start the backlight.

My panel (and anything from the last decade) uses LED backlights so I would not expect anything above 60V.
