Default Re: LCD/Screensavers

Burn in is due to uneven aging of the screen. CRT's and plasma displays are all susceptible since they use phosphors to show color, and phosphors do age with use.

LCD's don't have anything that ages so they can't get burn in. The worst that can happen with an LCD is the little microscopic rods that form in each cell when its charged can stay that way if left there for a while, resulting in what looks like burn-in. But, this can be fixed by rapidly turning the cell on and off. See this:

Actually what you were seeing was the dark parts staying kinda dark, the bright parts were more or less normal on the other hand. I've never heard of LCD image persistence being permanent if somebody takes steps to correct it.
