Why has my screen turned into a green screen?

[andyandrew2006]

It's like a slowing bright appear kinda thing. I'm confused. What is going on with my green screen? Examples are below.

Could be a faulty screen, you tried safe mode ?

If that persists even after a reboot, then I agree with mustang7757, the screen has failed. Bring it to a repair shop.
