First thing is first; CRTs have 'screen burn-ins' while LCDs have 'image persistence'. The two are clearly similar, but by no means the same. Now unless there is relevance in opening up a discussion on CRT 'screen burn-ins', i would like to keep the focus on LCDs and 'image persistence'. So here it goes..
Essentially, there are many different ways of avoiding and or removing 'image persistence' on LCDs, but one approach that i frequently read about on the net is the displaying of a full white image for as long as it takes to remove the persisting image, and the occasional displaying of this full white image to prevent a persisting image from occuring.
Now this theory seems to make sense, as it was recommended by numerous professional sources, but there is one catch that i cant seem to understand; If i were to display such a fullscreen white image on my LCD, then wouldn't the whole screen be imprinted with this white image, which in turn would make blacks appear more gray, as this would be the equivilant of reducing the contrast ratio on the display?
Thats my question.
