I think I can help with this. Basically anything that uses a phosphor or some other type of phosphorescent chemical to generate the image has a chance of image retention.
An LCD screen uses crystals that allow light (from the backlight) to passthrough or be blocked. These crystals can sometimes get aligned and stopping moving when the crystal stays at the same state for a while due to the same image being kept on the screen. This is known as image persistance. The solution to that is simply to send video noise to the display so that the crystals are being cycled for a few hours up to a day. So, this is not a permanent condition.
Plasma uses phosphors to generate the image. These phosphors can retain an image permanently which is image burn-in. Plasma manufacturers have done a number of things over the years to reduce the chance of burn-in including slightly offsetting the image so that if there is a static image it won't continually be the same on each pixel. Reducing the brightness can also help. Once an image is burned-in there is no way to change it on a plasma and plasma warranties do not cover burn-in.
Of course, CRTs were/are the worst and there are still many examples in bowling allies and small airports (for instance) of CRT burn-ins.
DLPs and LCOS-type projectors do not have burn-in issues even though most owner's manuals warn the user about the possibility of burn-ins (I'm told the lawyers suggest that the manufacturers include the warning for all types of TVs). OLED TVs, which generate the light from the organic compound, should not have any issues although I have not tested those types of TVs.Edited by alk3997 - 5/15/13 at 7:50am
