Do LCD screens emit more light if you leave them on for a long time?

Q: I used to keep my laptop's screen on all the time, aka screen saver. Now, I have the screen turn off after awhile. I noticed since I have done this, my LCD screen seems less bright, even on max brightness.

A: I have this too. I think that the pixels in the screen get "relaxed" and it takes a while for them to kick back in, kind of like some fluorescent lighting.
