Screen Display Tint

[The_Crow]

Greetings,

This morning when I opened my Macbook Air 2012, the display had a faded white tint.
No, it's not a brightness thing. I have it to maximum brightness but when I turned it down the tint went with it.

I tried to ask my stepfather who is in IT though not so savvy with Macs. When I brought the laptop to him, the tint went away but then when I got it back to where I'm sitting it came back. It has so far, remained.

What is this?

Thanx for the response, I apologize for my delay, I was out all Sunday and was a bit out of it yesterday.

In following instructions given to me on Apple support, I shut down then restarted my Macbook. When it restarted, the tint was gone and hasn't yet returned.
